Abstract
The aim of this study is to analyze the risk factors associated with the development of adenomatous and malignant polyps in the gallbladder. Adenomatous polyps of the gallbladder are considered precancerous and have a high likelihood of progressing into malignancy. Preoperatively, distinguishing between benign gallbladder polyps, adenomatous polyps, and malignant polyps is challenging. Therefore, the objective is to develop a neural network model that utilizes these risk factors to accurately predict the nature of polyps. This predictive model can be employed to differentiate the nature of polyps before surgery, enhancing diagnostic accuracy. A retrospective study was done on patients who had cholecystectomy surgeries at the Department of Hepatobiliary Surgery of the Second People's Hospital of Shenzhen between January 2017 and December 2022. The patients' clinical characteristics, lab results, and ultrasonographic indices were examined. Using risk variables for the growth of adenomatous and malignant polyps in the gallbladder, a neural network model for predicting the kind of polyps will be created. A normalized confusion matrix, PR, and ROC curve were used to evaluate the performance of the model. In this comprehensive study, we meticulously analyzed a total of 287 cases of benign gallbladder polyps, 15 cases of adenomatous polyps, and 27 cases of malignant polyps. The data analysis revealed several significant findings. Specifically, hepatitis B core antibody (95% CI -0.237 to 0.061, p < 0.001), number of polyps (95% CI -0.214 to -0.052, p = 0.001), polyp size (95% CI 0.038 to 0.051, p < 0.001), wall thickness (95% CI 0.042 to 0.081, p < 0.001), and gallbladder size (95% CI 0.185 to 0.367, p < 0.001) emerged as independent predictors for gallbladder adenomatous polyps and malignant polyps. Based on these significant findings, we developed a predictive classification model for gallbladder polyps, represented as follows, Predictive classification model for GBPs = -0.149 * core antibody - 0.033 * number of polyps + 0.045 * polyp size + 0.061 * wall thickness + 0.276 * gallbladder size - 4.313. To assess the predictive efficiency of the model, we employed precision-recall (PR) and receiver operating characteristic (ROC) curves. The area under the curve (AUC) for the prediction model was 0.945 and 0.930, respectively, indicating excellent predictive capability. We determined that a polyp size of 10 mm served as the optimal cutoff value for diagnosing gallbladder adenoma, with a sensitivity of 81.5% and specificity of 60.0%. For the diagnosis of gallbladder cancer, the sensitivity and specificity were 81.5% and 92.5%, respectively. These findings highlight the potential of our predictive model and provide valuable insights into accurate diagnosis and risk assessment for gallbladder polyps. We identified several risk factors associated with the development of adenomatous and malignant polyps in the gallbladder, including hepatitis B core antibodies, polyp number, polyp size, wall thickness, and gallbladder size. To address the need for accurate prediction, we introduced a novel neural network learning algorithm. This algorithm utilizes the aforementioned risk factors to predict the nature of gallbladder polyps. By accurately identifying the nature of these polyps, our model can assist patients in making informed decisions regarding their treatment and management strategies. This innovative approach aims to improve patient outcomes and enhance the overall effectiveness of care.

Opioid Prescribing Variation After Laparoscopic Cholecystectomy in the US Military Health System. J Surg Res 2024; 297:149-158. [PMID: 37604706 DOI: 10.1016/j.jss.2023.06.056] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/07/2023] [Revised: 06/26/2023] [Accepted: 06/28/2023] [Indexed: 08/23/2023]
Abstract
INTRODUCTION After laparoscopic cholecystectomy (LC), there is a wide variation in opioid prescription miligram morphine equivalent dose (MED) and refills across US medical institutions. Given wide variation and opioid prescription guidelines, it is essential to conduct thorough health services research across medical, surgical, and patient-level factors that can be implemented to improve system-wide prescribing practices. Therefore, this study describes discharge MED variation and opioid refill probability after emergent and nonemergent LC. MATERIALS AND METHODS This retrospective cohort study included medical record data of adult patients (N = 20,025) undergoing LC from January 2016 to June 2021 in the US Military Health System. Data visualizations and bivariate analyses examined prescription patterns across hospitals and evaluated the relationship between patient-level, care-level, and system-level factors and each outcome: discharge MED and opioid refill probability. Two generalized additive mixed models evaluated the relationship between predictors and each outcome. RESULTS There was a significant variation in opioid and nonopioid pain medication prescribing practices across hospitals. While several factors were associated with discharge MED and opioid refill probability, the strongest effects were related to time period (before versus after a June 2018 Defense Health Agency policy release) and receipt of an opioid/nonopioid combination medication. Despite decreases in MED, the MED remained almost twice the recommended dose per prior research. CONCLUSIONS Variation by hospital suggests the need for system-level changes that target genuine practice change and opioid stewardship. Inclusion of patient-reported outcomes, electronic health record decision support tools, and academic detailing programs may support system-level improvements.

Simultaneous cholecystectomy for asymptomatic gallstones during elective colorectal cancer surgery. J Gastrointest Surg 2024; 28:656-661. [PMID: 38704202 DOI: 10.1016/j.gassur.2024.02.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/31/2024] [Accepted: 02/03/2024] [Indexed: 05/06/2024]
Abstract
BACKGROUND Asymptomatic gallstones are commonly detected using preoperative imaging in patients with colorectal cancer (CRC), but its management remains a topic of debate. METHODS Clinicopathologic characteristics of patients who had asymptomatic gallstones presenting during the colorectal procedure were retrospectively reviewed. Medical records, including postoperative morbidity, mortality, and long-term gallstone-related diseases, were assessed. RESULTS Of 134 patients with CRC having asymptomatic gallstones, 89 underwent elective colorectal surgery only (observation group), and 45 underwent elective colorectal surgery with simultaneous cholecystectomy (cholecystectomy group). After propensity score matching (PSM), the complications were similar in the 2 groups. During the follow-up period, biliary complications were noted in 11 patients (12.4%) in the observation group within 2 years after the initial CRC surgery, but no case was found in the cholecystectomy group. After PSM, the incidence of long-term biliary complications remained significantly higher in the observation group than in the cholecystectomy group (26.5% vs 0.0%; P < .01). Multivariable logistic regression analysis identified female gender, old age (≥65 years old), and small multiple gallstones as independent risk factors for the development of long-term gallstone-related diseases in patients from the observation group. CONCLUSION Simultaneous prophylactic cholecystectomy during prepared, elective CRC surgery did not increase postoperative morbidity or mortality but decreased the risk of subsequent gallstone-related complications. Hence, simultaneous cholecystectomy might be a preferred therapeutic option for patients with CRC having asymptomatic gallstones in cases of elective surgery, especially for older patients (≥65 years old), female patients, and those with small multiple calculi.

Abstract
Introduction: Laparoscopic cholecystectomy (LC) during index hospitalization for gallstone pancreatitis is standard in adult populations. The objective of this study was to evaluate trends in use of LC and endoscopic retrograde cholangiopancreatography (ERCP) for children with gallstone pancreatitis. Materials and Methods: This retrospective cohort study used the Kids' Inpatient Database, spanning 2000-2019, to identify patients aged 18 years or younger with a principal diagnosis of gallstone pancreatitis. The Mann-Kendall trend test was used to assess trends over time. Results: Gallstone pancreatitis occurred in 5028 patients. The rate of LC during index hospitalization ranged from 55.4% to 63.8% (P = .76). Trends demonstrate that LC occurred on average hospital day 4.6 in 2000 and decreased to 3.4 in 2019 (P < .01). Among those undergoing LC, average length of stay (LOS) decreased from 6.8 days in 2000 to 5.1 days in 2019 (P < .01). The rate of ERCP alone decreased from 24.8% in 2000 to 14.0% in 2019 (P = .23). For those undergoing ERCP, average hospital day of ERCP decreased from 3.3 in 2000 to 2.3 in 2019 (P = .07). The rate of undergoing both an ERCP and LC decreased from 19.0% in 2000 to 8.5% in 2019 (P = .13). For patients who underwent either LC or ERCP, average LOS decreased from 7.0 days in 2000 to 5.1 days in 2019 (P < .01). For patients who did not undergo a procedure, average LOS decreased from 5.7 days in 2000 to 4.0 days in 2019 (P = .13). Conclusion: The proportion of LC performed during index hospitalizations for children with gallstone pancreatitis has been stable for two decades. However, trends indicate that interventions are occurring earlier, and LOS is becoming shorter.

Efficacy and outcome of indocyanine green-based intraoperative cholangiography using near-infrared fluorescence imaging: A prospective study. J Minim Access Surg 2024; 20:89-95. [PMID: 38240384 PMCID: PMC10898639 DOI: 10.4103/jmas.jmas_228_22] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2022] [Revised: 07/03/2023] [Accepted: 07/15/2023] [Indexed: 01/24/2024] Open
Abstract
INTRODUCTION The most dreaded complication during laparoscopic cholecystectomy still remains to be injury to the common bile duct. The primary cause for bile duct injury during LC is misinterpretation of the biliary anatomy. Intra-operative cholangiography was introduced as a means of reducing the chances of biliary injury, done using Fluoroscopic imaging or Near-infrared fluorescence imaging method. NIRF is one of the most popular imaging methods in biomedical sciences. Indocyanine Green is sterile and water soluble which completely binds to albumin and is excreted in bile. PATIENTS AND METHODS This prospective study was conducted among 70 patients between July 2020 and December 2021. Subjects were administered 5mg of ICG dye pre-operatively and procedure performed using Karl Storz HD image S1 system with a D-light P light source for NIRF imaging. RESULTS The average duration of surgery was 58.10 minutes. After calot's dissection, the CBD was visualized in 88.71 % patients, with a mean time to visualization at 26.33 minutes. The cystic duct was visualized in 87.3% cases with a mean time of visualization of 32.10 minutes. The hepatic duct was visualized in 28.57% and the hepatic duct-CBD confluence was visualized in 34.28% patients. CONCLUSION Near infrared imaging based intra-operative cholangiography, using Indocyanine Green dye, during Lap. Cholecystectomy is an easy, useful and inexpensive method of visualizing the biliary ductal anatomy.

Referral practices are associated with a delay in treatment of symptomatic cholelithiasis and cholecystitis. Am J Surg 2024; 227:96-99. [PMID: 37806893 DOI: 10.1016/j.amjsurg.2023.09.041] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2023] [Revised: 09/27/2023] [Accepted: 09/28/2023] [Indexed: 10/10/2023]
Abstract
BACKGROUND The project was performed to determine if referrals to non-surgical providers after an initial presentation of symptomatic cholelithiasis are associated with a delay in surgical management. METHODS A single institution chart review of all adult patients who underwent a cholecystectomy from 2015 to 2019 was completed. Quantitative data was analyzed using independent t-tests. RESULTS Of 574 reviewed, 482 patients met criteria. Following initial presentation, 295 (61.2%) received a referral to surgery and 187 (38.8%) received follow up with a non-surgical provider. Those in the latter group had a significantly longer time from initial symptom presentation to surgical evaluation (65.7 days vs. 10.3 days, p < 0.001) and cholecystectomy (102.0 days vs 39.1 days, p < 0.001) when compared to the surgery referral group. CONCLUSIONS This study demonstrated that cholecystectomy was significantly delayed for patients who had been referred to non-surgical providers after initial presentation, prolonging symptoms and increasing use of healthcare resources.

Effect of retrieval bags in preventing surgical site wound infection during elective laparoscopic cholecystectomy in liver cancer patients: A meta-analysis. Int Wound J 2023; 20:4031-4039. [PMID: 37424304 PMCID: PMC10681484 DOI: 10.1111/iwj.14292] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/04/2023] [Revised: 06/16/2023] [Accepted: 06/17/2023] [Indexed: 07/11/2023] Open
Abstract
A meta-analysis research was implemented to appraise the effect of retrieval bags (RBs) in preventing surgical site wound infection (SSWI) in elective laparoscopic cholecystectomy (ELC) in liver cancer (LC) patients. Inclusive literature research until April 2023 was done, and 1273 interconnected researches were reviewed. From a total of 11 researches that were chosen, 2559 ELC procedures in LC patients were at the starting point of the researches: 1273 of them were utilising RBs and 1286 were controls. Odds ratio (OR) and 95% confidence intervals (CIs) were utilised to appraise the consequence of RBs in preventing SSWI in ELC in LC patients by the dichotomous approach and a fixed or random model. RBs had significantly lower SSWI (OR, 0.54; 95% CI, 0.38-0.76, p < 0.001) compared with controls in ELC in LC patients. However, no significant difference was found between RBs and controls in ELC in LC patients in bile spillage (OR, 0.51; 95% CI, 0.21-1.24, p = 0.14), fascial extension (OR, 0.54; 95% CI, 0.07-4.11, p = 0.55), postoperative collection (OR, 0.66; 95% CI, 0.24-1.76, p = 0.40) and port site hernia (OR, 0.72; 95% CI, 0.25-2.06, p = 0.54). RBs had significantly lower SSWI, and no significant difference was found in bile spillage, fascial extension, postoperative collection and port site hernia compared with controls in ELC in LC patients. However, caution needs to be taken when interacting with its values because there was a low sample size in some of the chosen researches and a low number of researches were found for some of the comparisons in the meta-analysis.

The impact of interval cholecystectomy timing after percutaneous transhepatic cholecystostomy on post-operative adverse outcomes. Surg Endosc 2023; 37:9132-9138. [PMID: 37814166 DOI: 10.1007/s00464-023-10451-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2023] [Accepted: 09/06/2023] [Indexed: 10/11/2023]
Abstract
OBJECTIVE This study aims to explore how timing of interval of cholecystectomy (IC) after percutaneous transhepatic cholecystostomy tube (PTC) placement impacts post-operative outcomes. METHODS A retrospective database analysis of New York State SPARCs database of IC between 2005 and 2015. The timing for IC ranged between > 1 week and < 2 years. Patients undergoing this procedure were further divided into quartiles using 4-time intervals; 1-5 weeks (Q1), 5-8 weeks (Q2), 8-12 weeks(Q3), and > 12 weeks(Q4). The study's primary outcome was hospital length of stay (LOS). Secondary outcomes included discharge status, 30-day readmission, 30-day ED visit, and 90-day reoperation, surgery type, complication, and bile duct injury. Multivariable regression models were used to compare patients across the four-time intervals after adjusting for confounding factors. RESULTS A total of 1038 patients with a history of PTC followed by IC between > 1 week and < 2 years were included in the final analysis. The median time to IC was 7.7 weeks. Q2 and Q3 both had a significantly higher median LOS of 3 days versus Q1 and Q4 at median of 5 days (p < 0.0001). Patients from racial and ethnic minorities (e.g., African Americans and Hispanics) were more likely to get their IC after 12 weeks (p < 0.05). Further, Black patients had a significantly higher median LOS than White, non-Hispanic patients (8 days vs 4 days, p < 0.0001) and were more likely to have open procedure. Multivariable regression analysis identified shorter LOS during Q2 (Ratio, 0.76, 95%, 0.67-0.87, p < 0.0001), and Q3 (Ratio 0.75, 95% CI, 065-0.86, p < 0.0001) compared to those who got their IC in Q4. Similar findings exist when comparing Q2 and Q3 to those receiving treatment during Q1. CONCLUSION A time interval of 5-12 weeks between PTC and IC was associated with a decreased LOS. This study also suggests the persistence of racial disparities among these patients.

Management of acute cholecystitis in patients on anti-thrombotic therapy: A single center experience. Surg Open Sci 2023; 16:94-97. [PMID: 37808421 PMCID: PMC10551647 DOI: 10.1016/j.sopen.2023.09.022] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2023] [Accepted: 09/28/2023] [Indexed: 10/10/2023] Open
Abstract
Background Acute cholecystitis in patients on anti-thrombotic therapy (ATT) presents a clinical dilemma at the intersection between conflicting guidelines, specifically between timing of early operative management (OM) versus time-to-reversal of certain ATT agents. With growing recognition that nonoperative management (NOM) is associated with considerable morbidity, and evidence in the literature that early OM in patients on ATT is safe, we reviewed our own practice to examine how we addressed these conflicting guidelines. Materials and methods We performed a retrospective review of patients with acute cholecystitis between December 2017 and March 2022. Patients were classified as ATT or non-ATT; ATT patients were subdivided into anticoagulation (AC) and antiplatelet (AP) groups. Rates of OM were compared. Results 502 patients with acute cholecystitis were identified, 464 non-ATT and 38 ATT. 30 ATT patients were on AC, 7 on AP, and 1 on both. Non-ATT patients were significantly more likely to receive OM at index presentation compared to those on ATT: 89.9 % vs 63.2 % (p < 0.05). Subgroup analysis of the ATT group showed AP patients were significantly less likely to receive OM compared to those on AC, 12.5 % vs 77 % (p < 0.05). Conclusions At our institution, patients on ATT were significantly less likely to undergo OM for acute cholecystitis compared with non-ATT patients. Those on AC received OM significantly more than patients on AP. Further study is needed to better define the management of this growing population so that acute cholecystitis guidelines might address this issue in the future.

Abstract
Background Percutaneous cholecystostomy (PC) can be used as bridging or definitive therapy in some cases of acute cholecystitis. We aimed to compare hospital stay and survival of patients that underwent PC insertion because of acute calculus cholecystitis (ACC) compared to those who did not. Methods This is a retrospective study in which patients with gangrenous cholecystitis and perforation were excluded. Regression models were used to evaluate the influence of PC on mortality and hospital stay. Results Six hundred and eighty-three patients were admitted because of ACC, and 50 patients were referred to PC. Indication for PC insertion were high disease severity index (DSI, 8 pts) and failure of conservative treatment with total disease duration >7 days (42 pts). Those who underwent PC were older (76.0 ± 12.4 vs. 60.8 ± 19.2, P < 0.001); PC was associated with longer hospital stay (12.8 vs. 6.5 days) and higher one-year mortality (20% vs. 4.9%, P < 0.001). Among patients with non-severe disease severity index (DSI), PC was associated with longer length of hospital stay and higher one-year mortality compared to patients treated conservatively (9.9 ± 0.6 vs. 6.0 ± 0.2 days, and 16.7% vs. 4.0%, respectively, P < 0.001 for both). For patients with severe DSI, PC was associated with similar length of hospital stay and one-year mortality compared to similar patients treated conservatively (16.1 ± 8.1 vs. 18.4 ± 4.0 days, and 37.5% vs. 22.6%, respectively, P = 0.802 and P = 0.389, respectively). Conclusions In patients with mild-moderate DSI unresponsive to conservative treatment, PC may be associated with deteriorated prognosis compared to conservative treatment. The decision to insert PC in patients unresponsive to conservative therapy even with disease duration >7 days must be re-evaluated.

Abstract
Background The reasons for the recurrence of common bile duct stones (CBDS) in elderly patients after choledocholithotomy are still unclear. This study aims to establish a prediction model for CBDS recurrence by identifying risk factors. Methods We conducted a retrospective analysis of 1804 elderly patients aged 65 years and above who were diagnosed to have CBDS and were admitted to Nanjing First Hospital between January 1, 2010, and January 1, 2021. According to inclusion and exclusion criteria, 706 patients were selected for the final analysis. The patients were assigned to two groups according to the presence or absence of CBDS recurrence, and their clinical data were then statistically analyzed. Subsequently, a prediction model and nomogram were developed, evaluating effectiveness using the concordance index (C-index). Results Of the 706 elderly patients, 62 patients experienced CBDS recurrence after surgery, resulting in a recurrence rate of 8.8%. The multivariate Cox analysis showed that prior history of cholecystectomy (hazard ratio [HR] = 1.931, 95% confidence interval [CI]: 1.051-3.547, p = 0.034), white blood cell (WBC) count ≥11.0 × 109/L (HR = 2.923, 95% CI: 1.723-4.957, p < 0.001), preoperative total bilirubin (TBIL) level ≥ 36.5 mmol/L (HR = 2.172, 95% CI: 1.296-3.639, p = 0.003), number of stones ≥2 (HR = 2.093, 95% CI: 1.592-5.294, p = 0.001), maximum stone diameter ≥ 0.85 cm (HR = 1.940, 95% CI: 1.090-3.452, p = 0.024), and T-tube drainage (HR = 2.718, 95% CI: 1.230-6.010, p = 0.013) were independent risk factors of CBDS recurrence in elderly patients after choledocholithotomy. A postoperative CBDS recurrence prediction model was constructed with a C-index value of 0.758 (95% CI: 0.698-0.818) and internal validation value of 0.758 (95% CI: 0.641-0.875). Conclusion A history of cholecystectomy, WBC count ≥11.0 × 109/L, preoperative TBIL level ≥ 36.5 mmol/L, number of stones ≥2, maximum stone diameter ≥ 0.85 cm, and T-tube drainage are the independent risk factors of CBDS recurrence after choledocholithotomy in elderly patients. Our developed prediction model for CBDS recurrence has good predictive ability and can help predict the prognosis of patients with CBDS.

Abstract
About 20% of adults worldwide have gallstones which are solid conglomerates in the biliary tree made of cholesterol monohydrate crystals, mucin, calcium bilirubinate, and protein aggregates. About 20% of gallstone patients will definitively develop gallstone disease, a condition which consists of gallstone-related symptoms and/or complications requiring medical therapy, endoscopic procedures, and/or cholecystectomy. Gallstones represent one of the most prevalent digestive disorders in Western countries and patients with gallstone disease are one of the largest categories admitted to European hospitals. About 80% of gallstones in Western countries are made of cholesterol due to disturbed cholesterol homeostasis which involves the liver, the gallbladder and the intestine on a genetic background. The incidence of cholesterol gallstones is dramatically increasing in parallel with the global epidemic of insulin resistance, type 2 diabetes, expansion of visceral adiposity, obesity, and metabolic syndrome. In this context, gallstones can be largely considered a metabolic dysfunction-associated gallstone disease, a condition prone to specific and systemic preventive measures. In this review we discuss the key pathogenic and clinical aspects of gallstones, as the main clinical consequences of metabolic dysfunction-associated disease.

[PMID: 37899892 PMCID: PMC10600618 DOI: 10.7759/cureus.47634] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 10/24/2023] [Indexed: 10/31/2023] Open
Abstract
Background Up to 15% of patients with cholelithiasis have choledocholithiasis, with almost 10% not detected pre-operatively. Our study aims to quantify the prevalence of incidental choledocholithiasis during routine intra-operative cholangiogram (IOC), identify the best management pathway, and identify reliable pre-operative factors to predict choledocholithiasis. Methods We conducted a single-centre, retrospective cohort study at St John of God Midland Hospital in Western Australia, Perth, on 880 consecutive patients who underwent cholecystectomies performed by 15 surgeons between January 2, 2020, and December 30, 2021. Results The overall choledocholithiasis rates were 10.6% (93), with 4.0% (35) diagnosed pre-operatively and 6.6% (58) diagnosed during IOC. In all, 50% of incidental choledocholithiasis during IOC were managed with hyoscine butylbromide, with a 55.2% success rate; 22.4% of patients received octreotide, with a 61.5% success rate; and 8.6% of patients underwent trans-cystic bile duct exploration (TCBE) and 8.6% underwent postoperative endoscopic retrograde cholangiopancreatography (ERCP), both with 100% success rates. Choledocholithiasis most commonly presents with gallstone pancreatitis, with a median aspartate aminotransferase (AST) level 7.2 times and alanine transaminase (ALT) level 7.8 times higher than those of patients without choledocholithiasis. Magnetic resonance cholangiopancreatography (MRCP) was the most sensitive in identifying choledocholithiasis with a 66.7% pickup rate. The median common bile duct (CBD) diameter on ultrasound was 8 mm, computerised tomography scans were 11 mm, and MRCP was 9 mm. Conclusion One in 10 cholecystectomies will be complicated with choledocholithiasis, and over half will be incidentally diagnosed during routine IOC. We propose IOC in all cases and hyoscine butylbromide, octreotide, and saline flushes as first-line treatment; if unsuccessful, TCBE is performed. Gallstone pancreatitis, markedly elevated AST/ALT, and imaging showing CBD ≥8 mm may serve as early predictors of choledocholithiasis.

Clinical Predictive Score for Cholecystectomy Wound Infection: WEBAC Score. J Gastrointest Surg 2023; 27:1876-1882. [PMID: 37340105 DOI: 10.1007/s11605-023-05750-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/08/2023] [Accepted: 06/03/2023] [Indexed: 06/22/2023]
Abstract
BACKGROUND Most common surgical complications in cholecystectomy are surgical site infections (SSIs). SSIs have many factors, including patient, surgical, and disease factors. This study aims to find the factors which relate to SSIs 30 days after cholecystectomy and contribute to the scoring system to predict SSIs. METHODS AND MATERIAL The data of patients who underwent cholecystectomy from January 2015 to December 2019 were retrospectively collected from a prospectively collected infectious control registry. The SSI was defined following the CDC criteria and assessed before discharge and at a 1-month follow-up. Variables that were independently predictive of the increased SSIs were included in the risk score. RESULTS The patients who underwent cholecystectomy were 949, which were divided into 28 patients who had SSIs and 921 who had no SSIs. The rate of SSIs was 3%. The factors related to SSI in cholecystectomy were age ≥ 60 years (p = 0.045), history of smoking (p = 0.004), retrieval bag use (p = 0.005), preoperative ERCP (p = 0.02), and wound class III and IV (p = 0.007). Risk assessment was using five variables (WEBAC): (1) wound classifications, (2) preoperative ERCP, (3) retrieval plastic bag use, (4) aged ≥ 60 years, and (5) history of smoking (cigarette). If patients were aged ≥ 60 years and had a history of smoking, no plastic bag use, preoperative ERCP, or wound class III or IV, these parameters would all be scored 1 each. The WEBAC score revealed the probability of SSIs in cholecystectomy wounds. CONCLUSION The WEBAC score represents a convenient and simple tool to predict the probability of SSI in the patients who underwent cholecystectomy and might increase the surgeons' awareness of postoperative SSI.

A proposed difficulty grading system for laparoscopic bile duct exploration: benefits to clinical practice, training and research. Surg Endosc 2023; 37:7012-7023. [PMID: 37349591 PMCID: PMC10462500 DOI: 10.1007/s00464-023-10169-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2023] [Accepted: 05/28/2023] [Indexed: 06/24/2023]
Abstract
BACKGROUND A gap remains between the mounting evidence for single session management of bile duct stones and the adoption of this approach. Laparoscopic bile duct exploration (LBDE) is limited by the scarcity of training opportunities and adequate equipment and by the perception that the technique requires a high skill-set. The aim of this study was to create a new classification of difficulty based on operative characteristics and to stratify postoperative outcomes of easy vs. difficult LBDE irrespective of the surgeon's experience. METHODS A cohort of 1335 LBDEs was classified according to the location, number and size of ductal stones, the retrieval technique, utilisation of choledochoscopy and specific biliary pathologies encountered. A combination of features indicated easy (Grades I and II A & B) or difficult (Grades III A and B, IV and V) transcystic or transcholedochal explorations. RESULTS 78.3% of patients with acute cholecystitis or pancreatitis, 37% with jaundice and 46% with cholangitis had easy explorations. Difficult explorations were more likely to present as emergencies, with obstructive jaundice, previous sphincterotomy and dilated bile ducts on ultrasound scans. 77.7% of easy explorations were transcystic and 62.3% of difficult explorations transductal. Choledochoscopy was utilised in 23.4% of easy vs. 98% of difficult explorations. The use of biliary drains, open conversions, median operative time, biliary-related complications, hospital stay, readmissions, and retained stones increased with the difficulty grade. Grades I and II patients had 2 or more hospital episodes in 26.5% vs. 41.2% for grades III to V. There were 2 deaths in difficulty Grade V and one in Grade IIB. CONCLUSION Difficulty grading of LBDE is useful in predicting outcomes and facilitating comparison between studies. It ensures fair structuring and assessment of training and progress of the learning curve. LBDEs were easy in 72% with 77% completed transcystically. This may encourage more units to adopt this approach.

A mixed-methods study to define Textbook Outcome for the treatment of patients with uncomplicated symptomatic gallstone disease with hospital variation analyses in Dutch trial data. HPB (Oxford) 2023; 25:1000-1010. [PMID: 37301634 DOI: 10.1016/j.hpb.2023.05.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/28/2023] [Revised: 05/03/2023] [Accepted: 05/07/2023] [Indexed: 06/12/2023]
Abstract
BACKGROUND International consensus on the ideal outcome for treatment of uncomplicated symptomatic gallstone disease is absent. This mixed-method study defined a Textbook Outcome (TO) for this large group of patients. METHODS First, expert meetings were organised with stakeholders to design the survey and identify possible outcomes. To reach consensus, results from expert meetings were converted in a survey for clinicians and for patients. During the final expert meeting, clinicians and patients discussed survey outcomes and a definitive TO was formulated. Subsequently, TO-rate and hospital variation were analysed in Dutch hospital data from patients with uncomplicated gallstone disease. RESULTS First expert meetings returned 32 outcomes. Outcomes were distributed in a survey among 830 clinicians from 81 countries and 645 Dutch patients. Consensus-based TO was defined as no more biliary colic, no biliary and surgical complications, and the absence or reduction of abdominal pain. Analysis of individual patient data showed that TO was achieved in 64.2% (1002/1561). Adjusted-TO rates showed modest variation between hospitals (56.6-74.9%). CONCLUSION TO for treatment of uncomplicated gallstone disease was defined as no more biliary colic, no biliary and surgical complications, and absence or reduction of abdominal pain.TO may optimise consistent outcome reporting in care and guidelines for treating uncomplicated gallstone disease.

Abstract
Backgrounds/Aims Laparoscopic cholecystectomy within one week of acute cholecystitis is considered safe and advantageous. Surgery beyond first week is reserved for non-resolving attack or complications. To compare clinical outcomes of patients undergoing laparoscopic cholecystectomy in the first week and between two to six weeks of an attack of acute cholecystitis. Methods In an analysis of a prospectively maintained database, all patients who underwent laparoscopic cholecystectomy for acute cholecystitis were divided into two groups: group A, operated within one week; and group B, operated between two to six weeks of an attack. Main variables studied were mean operative time, conversion to open cholecystectomy, morbidity profile, and duration of hospital stay. Results A total of 116 patients (74 in group A and 42 in group B) were included. Mean interval between onset of symptoms & surgery was five days (range, 1-7 days) in group A and 12 days (range, 8-20 days) in group B. Operative time and incidence of subtotal cholecystectomy were higher in group B (statistically not significant). Mean postoperative stay was 2 days in group A and 3 days in group B. Laparoscopy was converted to open cholecystectomy in two patients in each group. There was no incidence of biliary injury. One patient in group B died during the postoperative period due to continued sepsis and multiorgan failure. Conclusions In tertiary care setting, with adequate surgical expertise, laparoscopic cholecystectomy can be safely performed in patients with acute cholecystitis irrespective of the time of presentation.

Patients with Clinically Suspected Gallstone Disease: A More Selective Ultrasound May Improve Treatment Related Outcomes. J Clin Med 2023; 12:4162. [PMID: 37373855 DOI: 10.3390/jcm12124162] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2023] [Revised: 06/14/2023] [Accepted: 06/15/2023] [Indexed: 06/29/2023] Open
Abstract
This study aimed to quantify the confirmation of gallstones on ultrasound (US) in patients with suspicion of gallstone disease. To aid general practitioners (GPs) in diagnostic workup, a model to predict gallstones was developed. A prospective cohort study was conducted in two Dutch general hospitals. Patients (≥18 years) were eligible for inclusion when referred by GPs for US with suspicion of gallstones. The primary outcome was the confirmation of gallstones on US. A multivariable regression model was developed to predict the presence of gallstones. In total, 177 patients were referred with a clinical suspicion of gallstones. Gallstones were found in 64 of 177 patients (36.2%). Patients with gallstones reported higher pain scores (VAS 8.0 vs. 6.0, p < 0.001), less frequent pain (21.9% vs. 54.9%, p < 0.001), and more often met criteria for biliary colic (62.5% vs. 44.2%, p = 0.023). Predictors for the presence of gallstones were a higher pain score, frequency of pain less than weekly, biliary colic, and an absence of heartburn. The model showed good discrimination between patients with and without gallstones (C-statistic 0.73, range: 0.68-0.76). Clinical diagnosis of symptomatic gallstone disease is challenging. The model developed in this study may aid in the selection of patients for referral and improve treatment related outcomes.

Abstract
Background Laparoscopic cholecystectomy (LC) has increasingly been accepted as the procedure of choice for the treatment of acute cholecystitis (AC). However, the timing of this procedure in the management of AC remains controversial. Hence this study was conducted to assess the feasibility of early laparoscopic cholecystectomy in acute cholecystitis. Materials and methods Patients who presented with symptoms of acute cholecystitis such as pain and tenderness in the right upper quadrant, systemic signs of inflammation, and positive ultrasound findings according to Tokyo guidelines were included for evaluation. Group 1 includes patients presented within 24 hours of the onset of symptoms whereas those presented between 25 and 72 hours of the onset of symptoms belonged to Group 2. All patients were taken up for early LC after assessment. Intraoperative and postoperative complications were analysed. Results Out of 120 patients, 37 belonged to Group 1 (30.83%) and 83 belonged to Group 2 (69.17%). There was a significant difference between the study groups in terms of certain demographic, laboratory findings and duration of surgery. None of the patients in Group 1 developed postoperative complications, whereas one patient in Group 2 had a bile leak on postoperative Day 2. Group 2 had a higher conversion rate to open procedure (p = 0.059). The mean duration of hospital stay for patients in Groups 1 and 2 were 3 and 3.3 days, respectively. Conclusion Laparoscopic cholecystectomy is safe and feasible with minimal conversion rates in patients presenting with early symptoms of AC. With the availability of good visualisation, optics, instruments and energy sources, good outcomes can be achieved.

Awake laparoscopic cholecystectomy: A case report and review of literature. World J Clin Cases 2023; 11:3002-3009. [PMID: 37215416 PMCID: PMC10198068 DOI: 10.12998/wjcc.v11.i13.3002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/14/2022] [Revised: 10/21/2022] [Accepted: 11/10/2022] [Indexed: 04/25/2023] Open
Abstract
BACKGROUND Laparoscopic cholecystectomy (LC) is one of the most widely practiced surgical procedures in abdominal surgery. Patients undergo LC during general anaesthesia; however, in recent years, several studies have suggested the ability to perform LC in patients who are awake. We report a case of awake LC and a literature review.
CASE SUMMARY A 69-year-old patient with severe pulmonary disease affected by cholelithiasis was scheduled for LC under regional anaesthesia. We first performed peridural anaesthesia at the T8-T9 level and then spinal anaesthesia at the T12-L1 level. The procedure was managed in total comfort for both the patient and the surgeon. The intra-abdominal pressure was 8 mmHg. The patient remained stable throughout the procedure, and the postoperative course was uneventful.
CONCLUSION Evidence has warranted the safe use of spinal and epidural anaesthesia, with minimal side effects easily managed with medications. Regional anaesthesia in selected patients may provide some advantages over general anaesthesia, such as no airway manipulation, maintenance of spontaneous breathing, effective postoperative analgesia, less nausea and vomiting, and early recovery. However, this technique for LC is not widely used in Europe; this is the first case reported in Italy in the literature. Regional anaesthesia is feasible and safe in performing some types of laparoscopic procedures. Further studies should be carried out to introduce this type of anaesthesia in routine clinical practice.

Abstract
Introduction Laparoscopic cholecystectomy is a minimal access procedure in which the gallbladder is removed by laparoscopic techniques. Effective training for laparoscopic surgery should focus on not only understanding the anatomy and procedural steps but also acquiring the specific gestures and techniques of this type of surgery that may differ from those used in traditional open surgery. The aim of our study was to analyze whether the laparoscopic cholecystectomy performed by surgeons in training is a safe procedure. Material and methods This is a retrospective review of 433 patients who were divided into two groups: laparoscopic cholecystectomies performed by trainees and those performed by senior surgeons. Results Around 66% of surgeries were performed by resident surgeons. There was no demographic difference between residents and senior surgeons. Operative time was significantly longer in the residents' group compared to senior surgeons' group (96 minutes vs 61 minutes; p<0.001). The overall intra- and post-operative complication rates were 3.1% and 2.5%, respectively, with no significant difference between the two groups (p=0.368 and p=0.223). Conversion to open laparotomy was required in 8% of cases in each group (p=0.538). The mean length of hospital stay after surgery was significantly longer in patients operated by residents (p<0.001). We did not notice any case of mortality in both groups.

Abstract
Background and Objective: Choledocholithiasis is a frequent pathology, unfortunately when its endoscopic management fails, there is no consensus of how it should be addressed. The aim of this study was to evaluate the safety, feasibility, and long-term outcomes of laparoscopic common bile duct exploration (LCBDE) using electrosurgery (coagulation) for choledochotomy followed by primary closure after endoscopic treatment failure. Materials and Methods: A retrospective cohort study of patients who underwent LCBDE from 2013 to 2018 was conducted in Bogotá, Colombia. Clinical demographics, operative outcomes, recurrence rate of common bile duct stones, and long-term bile duct complications were analyzed. A descriptive analysis was performed. Results: A total of 168 patients were analyzed. Most of the patients were males (53.37%) with a median age of 73 years with no comorbidities (65%). Stone clearance was successful in 167 patients (99.4%). Nonlethal complications were noted in 3 patients during the surgery or in the immediate postoperative (1.79%) and managed with T-tube or endoscopically. No cases of mortality surgery related were observed. There were no signs of any type of biliary injury or stricture observed in any of the patients during the 24-month follow-up period. Conclusions: LCBDE with diathermy and primary closure is a safe and effective treatment option for choledocholithiasis for failed endoscopic retrograde cholangiopancreatography in terms of long-term outcome as well as short-term outcome.

Abstract
This analysis aims to evaluate the comparative outcomes of gallbladder extraction with a bag versus direct extraction in laparoscopic cholecystectomy (LC). A systematic online search was conducted using the following databases: PubMed, Scopus, Cochrane database, The Virtual Health Library, Clinical trials.gov, and Science Direct. Comparative studies comparing bag versus direct extraction of the gallbladder in LC were included. Outcomes were surgical site infection (SSI), the extension of fascial defect to extract the gallbladder, intra-abdominal collection, bile spillage, and port-site hernia. Revman 5.4 (Cochrane, London, United Kingdom) was used for the data analysis. The results show eight studies were eligible to be included in this review with a total number of 1805 patients divided between endo-bag (n=835) and direct extraction (n=970). Four of the included studies were randomized controlled trials (RCTs) while the rest were observational studies. The rate of SSI and bile spillage were significantly higher in the direct extraction group: odds ratio (OR)=2.50, p=0.006 and OR=2.83, p=0.01, respectively. Comparable results were observed regarding intra-abdominal collection between the two groups(OR=0.01, p=0.51). However, the extension of a fascial defect was higher in the endo-bag group (OR=0.22, p=0.00001), and no difference was observed regarding the port-site hernia rate (OR-0.70, p=0.55). In conclusion, extraction of the gallbladder with an endo-bag provides a lower rate of SSI and bile spillage with similar results regarding post-operative intra-abdominal collection. Although with the endo-bag, the fascial defect will more likely need to be increased to extract the gallbladder. However, the port-site hernia rate remains similar between the two groups.

Abstract
OBJECTIVE This study aims to examine the indications, techniques, and outcomes of choledochoscopy during laparoscopic bile duct exploration and evaluate the results of the wiper blade maneuver (WBM) for transcystic intrahepatic choledochoscopy. SUMMARY OF BACKGROUND DATA Choledochoscopy has traditionally been integral to bile duct explorations. However, laparoscopic era studies have reported wide variations in choledochoscopy availability and use, particularly with the increasing role of transcystic exploration. METHODS The indications, techniques, and operative and postoperative data on choledochoscopy collected prospectively during transcystic and choledo- chotomy explorations were analyzed. The success rates of the WBM were evaluated for the 3 mm and 5 mm choledochoscopes. RESULTS Of 935 choledochoscopies, 4 were performed during laparoscopic cholecystectomies and 931 during 1320 bile duct explorations (70.5%); 486 transcystic choledochoscopies (52%) and 445 through choledochotomies (48%). Transcystic choledochoscopy was utilized more often than blind exploration (55.7%% vs 44.3%) in patients with emergency admissions, jaundice, dilated bile ducts on preoperative imaging, wide cystic ducts, and large, numerous or impacted bile duct stones. Intrahepatic choledochoscopy was successful in 70% using the 3 mm scope and 81% with the 5 mm scope. Choledochoscopy was necessary in all 124 explorations for impacted stones. Twenty retained stones (2.1%) were encountered but no choledochoscopy related complications. CONCLUSIONS Choledochoscopy should always be performed during a chol- edochotomy, particularly with multiple and intrahepatic stones, reducing the incidence of retained stones. Transcystic choledochoscopy was utilized in over 50% of explorations, increasing their rate of success. When attempted, the transcystic WBM achieves intrahepatic access in 70%-80%. It should be part of the training curriculum.

Abstract
BACKGROUND With medical advancement, common bile duct stones were treated by endoscopic retrograde cholangiopancreatography (ERCP), considered the standard treatment. However, ERCP might induce complications including pancreatitis and cholecystitis that could affect a subsequent laparoscopic cholecystectomy (LC), leading to conversion to open cholecystectomy perioperative complications. It is not yet known whether or not the time interval between ERCP and LC plays a role in increasing conversion rate and complications. Bides, in the traditional sense, after ERCP, for avoiding edema performing LC was several weeks later. Even no one study could definite whether early laparoscopic cholecystectomy after ERCP affected the prognosis or not clearly. OBJECTIVE Comparing some different surgical timings of LC after ERCP. METHOD Searching databases consist of all kinds of searching tools, such as Medline, Cochrane Library, Embase, PubMed, etc. All the included studies should meet the demands of this meta-analysis. In all interest outcomes below, we took full advantage of RevMan5 and WinBUGS to assess; the main measure was odds ratio (OR) with 95% confidence. Moreover, considering the inconsistency of the specific time points in different studies, we set a subgroup to analyze the timing of LC after ERCP. For this part, Bayesian network meta-analysis was done with WinBUGS. RESULT In the pool of conversion rate, the result suggested that the early LC group was equal compared with late LC (OR = 0.68, I2 = 0%, P = .23). Besides, regarding morbidity, there was no significant difference between the 2 groups (OR = 0.74, I2 = 0%, P = .26). However, early LC, especially for laparoscopic-endoscopic rendezvous that belonged to performing LC within 24 hours could reduce the post-ERCP pancreatitis (OR = 0.16, I2 = 29%, P = .0003). Considering early LC included a wide time and was not precise enough, we set a subgroup by Bayesian network, and the result suggested that performing LC during 24 to 72 hours was the lowest conversion rate (rank 1: 0%). CONCLUSION In the present study, LC within 24 to 72 hours conferred advantages in terms of the conversion rate, with no recurrence of acute cholecystitis episodes.

Abstract
Choledocholithiasis is more common in acute cholecystitis than in elective situations. Preoperative diagnosis of choledocholithiasis is essential to facilitate adequate planning of CBD (common bile duct) stone removal, preferably performed as a single-stage procedure. The purpose of this study was to test the feasibility of routine preoperative magnetic resonance cholangiopancreatography (MRCP) in acute cholecystitis followed by consequent cholecystectomy. A total of 180 consecutive patients operated for acute cholecystitis between January 2019 and December 2019 were prospectively enrolled. Preoperative routine MRCP was performed for bile duct evaluation when feasible. The control cohort consisted of 180 consecutive patients undergoing emergency laparoscopic cholecystectomy before the study period. Intraoperative cholangiography was used routinely in both groups when technically achievable. We examined the proportion of patients recruited in preoperative MRCP, possible time delay to MRCP and surgery, and the incidence of CBD stones compared to the control cohort. Routine MRCP in acute cholecystitis was achieved in 114/180 (63%) patients compared to 42/180 (23.3%) patients of the control group. The triage time from emergency to MRCP and the operating theatre was similar in both cohorts. The percentage of patients diagnosed with choledocholithiasis in the study group was notably higher (almost 18% vs 11%), p < 0.05. After a median follow-up time of 2.5 years in the study group and almost 4 years in the control group, recurrent choledocholithiasis was not detected in either group. Routine MRCP in patients with acute cholecystitis can be implemented with a fair execution rate in a population-based setting with minor effects on hospital stay and delays but higher detection of choledocholithiasis. We observed no additional benefit compared to the selective use of MRCP. However, routine preoperative MRCP allows an advantage when considering the appropriate exploration method if choledocholithiasis is detected.

Evidence-based surgery for laparoscopic cholecystectomy. Surg Open Sci 2022; 10:116-134.

Abstract
Background Laparoscopic cholecystectomy is frequently performed for acute cholecystitis and symptomatic cholelithiasis. Considerable variation in the execution of key steps of the operation remains. We conducted a systematic review of evidence regarding best practices for critical intraoperative steps for laparoscopic cholecystectomy. Methods We identified 5 main intraoperative decision points in laparoscopic cholecystectomy: (1) number and position of laparoscopic ports; (2) identification of cystic artery and duct; (3) division of cystic artery and duct; (4) indications for subtotal cholecystectomy; and (5) retrieval of the gallbladder. PubMed, EMBASE, and Web of Science were queried for relevant studies. Randomized controlled trials and systematic reviews were included for analysis, and evidence quality was assessed using the Grading of Recommendations, Assessment, Development, and Evaluation framework. Results Fifty-two articles were included. Although all port configurations were comparable from a safety standpoint, fewer ports sometimes resulted in improved cosmesis or decreased pain but longer operative times. The critical view of safety should be obtained for identification of the cystic duct and artery but may be obtained through fundus-first dissection and augmented with cholangiography or ultrasound. Insufficient evidence exists to compare harmonic-shear, clipless ligation against clip ligation of the cystic duct and artery. Stump closure during subtotal cholecystectomy may reduce rates of bile leak and reoperation. Use of retrieval bag for gallbladder extraction results in minimal benefit. Most studies were underpowered to detect differences in incidence of rare complications. Conclusion Key operative steps of laparoscopic cholecystectomy should be informed by both compiled data and surgeon preference/patient considerations.

Value of prediction model in distinguishing gallbladder adenoma from cholesterol polyp. J Gastroenterol Hepatol 2022; 37:1893-1900. [PMID: 35750491 DOI: 10.1111/jgh.15928] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/29/2022] [Revised: 05/25/2022] [Accepted: 06/18/2022] [Indexed: 12/09/2022]
Abstract
BACKGROUND AND AIM Gallbladder adenomatous polyp is a pre-cancerous neoplasm, and it is difficult to classify from cholesterol polyps before cholecystectomy. The study aimed to clarify the risk characteristics of gallbladder adenomas and establish a prediction model to differentiate gallbladder adenomas from cholesterol polyp lesions. METHODS From May 2019 to December 2021, the patients underwent cholecystectomy in the Shanghai Eastern Hepatobiliary Surgery Hospital were retrospectively reviewed. According to the permanent pathology test, the patients were divided into adenomas and cholesterol polyps groups. All the included cases received ultrasound equipment examinations before cholecystectomy and their clinical information were completely recorded. Then the patients' baseline characteristics and ultrasound imaging variables were analyzed by logistic regression. Finally, a predictive model for gallbladder adenomas will be established and assessed based on the independent risk factors. RESULTS A total of 423 cases including 296 cholesterol polyps and 127 gallbladder adenomas were analyzed in detail. Multivariate logistic regression analysis revealed that solitary polyp lesion (OR = 2.954, 95% CI 1.759-4.960, P < 0.001), the maximal diameter of lesions (OR = 1.244, 95% CI 1.169-1.324, P < 0.001), and irregular shape of polyp lesions (OR = 5.549, 95% CI 1.979-15.560, P = 0.001) were the independent predictive factors of gallbladder adenomas. According to the results, regression equation of logit(P) = -3.828 + 1.083*number of gallbladder polyps lesions (GPLs) + 0.218*diameter of GPLs + 1.714*shape of GPLs was established. Area under the curve (AUC) was 0.828 (95% CI 0.782-0.874, P < 0.001). When logit P > 0.204, the sensitivity of estimating adenoma was 79.5%, the specificity of recognizing adenoma was 70.6%, and the whole correct ratio was 73.3%. While the AUC of diameter (10 mm) being a predictive factor in this study was only 0.790 (95% CI 0.741-0.839, P < 0.001). And the sensitivity and specificity of 10 mm as the optimal diagnostic cutoff value to diagnose adenomas were 74.8% and 65.9%, respectively. CONCLUSIONS The risk factors of solitary polyp lesion, larger diameter, and irregular morphology feature of polyp lesions were significantly related to gallbladder adenomas. And the predictive model established in the study can effectively identify adenomas from cholesterol polyps and help patients to select the optimal treatment protocol.

Laparoscopic surgery for gallstones or common bile duct stones: A stably safe and feasible surgical strategy for patients with a history of upper abdominal surgery. Front Surg 2022; 9:991684. [PMID: 36248372 PMCID: PMC9562259 DOI: 10.3389/fsurg.2022.991684] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2022] [Accepted: 09/08/2022] [Indexed: 12/03/2022] Open
Abstract
Backgrounds/Aims A history of upper abdominal surgery has been identified as a relative contraindication for laparoscopy. This study aimed to compare the clinical efficacy and safety of laparoscopic cholecystectomy (LC) and laparoscopic common bile duct exploration (LCBDE) in patients with and without previous upper abdominal surgery. Methods In total, 131 patients with previous upper abdominal surgery and 64 without upper abdominal surgery underwent LC or LCBDE between September 2017 and September 2021 at the Shengjing Hospital of China Medical University. Patients with previous upper abdominal surgery were divided into four groups: group A included patients with previous right upper abdominal surgery who underwent LC (n = 17), group B included patients with previous other upper abdominal surgery who underwent LC (n = 66), group C included patients with previous right upper abdominal surgery who underwent LCBDE (n = 30), and group D included patients with previous other upper abdominal surgery who underwent LCBDE (n = 18). Patient demographics and perioperative outcomes were retrospectively analyzed. Results The preoperative liver function indexes showed no significant difference between the observation and control groups. For patients who underwent LC, groups A and B had more abdominal adhesions than the control group. One case was converted to open surgery in each of groups A and B. There was no statistical difference in operation time, estimated blood loss, postoperative hospital stay, and drainage volume. For patients who underwent LCBDE, groups C and D had more estimated blood loss than the control group (group C, 41.33 ± 50.84 vs. 18.97 ± 13.12 ml, p = 0.026; group D, 66.11 ± 87.46 vs. 18.97 ± 13.12 ml, p = 0.036). Compared with the control group, group C exhibited longer operative time (173.87 ± 60.91 vs. 138.38 ± 57.38 min, p = 0.025), higher drainage volume (296.83 ± 282.97 vs. 150.83 ± 127.04 ml, p = 0.015), and longer postoperative hospital stay (7.97 ± 3.68 vs. 6.17 ± 1.63 days, p = 0.021). There was no mortality in all groups. Conclusions LC or LCBDE is a safe and feasible procedure for experienced laparoscopic surgeons to perform on patients with previous upper abdominal surgery.

Abstract
INTRODUCTION Past education literature has shown benefits for random practice schedules (termed contextual interference) for skills retention and transfer to novel tasks. The purpose of fundamentals of laparoscopic surgery (FLS) training is to develop skills in simulation and transfer to new in vivo intraoperative experiences. The study objective was to assess whether individuals trained over a fixed number of trials in the FLS tasks would outperform untrained controls on an unpracticed previously validated bile duct cannulation task and scoring system and to determine whether random training schedules conferred any relative advantage. METHODS 44 trainees with no laparoscopic experience were recruited to participate. 35 were randomized to practice the FLS tasks using either a blocked or random training schedule. Nine were randomized to no additional training (controls). Participant performance was measured throughout training to monitor skills acquisition and were then tested on an unpracticed bile duct cannulation simulation task 4 to 6 weeks later. Outcomes included previously validated FLS scores and hand-motion analyses. RESULTS All 44 participants completed the study. Trained individuals in both groups showed significant improvements in all FLS tasks after training. There were no differences between groups in performance on the cannulation task median scores (Blocked: 89.8 [IQR:37.6]; Random: 83.2 [32.3]; Control: 83.6 [19.1]; p = 0.955), number of hand motions (Blocked: 42.5 [IQR:130.3]; Random: 75.3 [111.3]; Control: 63.0 [71.8]; p = 0.912), or distance traveled by participants hands (Blocked: 2.0 m [IQR:5.8]; Random: 3.8 [8.9]; Control: 2.6 [2.5]; p = 0.816). Cannulation task performance had no correlation with total FLS performance, R2 linear = 0.014, p = 0.445. CONCLUSIONS Skills acquired from conventional FLS tasks did not effectively transfer to a laparoscopic bile duct cannulation task. Neither blocked nor random practice schedules conferred a relative advantage. These findings provide evidence that cannulation is a distinct skill from what is taught and assessed in FLS.

Cholecystectomy after endoscopic sphincterotomy in elderly: A dilemma. JOURNAL OF SURGERY AND MEDICINE 2022.

Abstract
Background/Aim: Although cholecystectomy is recommended by many guidelines after endoscopic retrograde cholangiopancreatography (ERCP) for gallstones, the necessity of cholecystectomy in geriatric patients is a matter of debate. Here we compare the outcomes of new biliary events in cholecystectomized and non-cholecystectomized patients of geriatric age after ERCP for suspected choledocholithiasis.
Methods: Non-cholecystectomized patients who underwent ERCP for choledocholithiasis from 2015 to 2017 were included in this retrospective cohort study. Patients with other biliary pathologies, incomplete clearance of common bile duct stones, and those who could not be reached at follow-up were excluded from the study. Biliary events (cholecystitis, cholangitis, pancreatitis, re-ERCP) were evaluated by considering age groups in patients with and without cholecystectomy in their follow-up after sphincterotomy.
Results: A total of 284 patients were followed for an average of 69.77 (0.2) months. The cumulative incidence of biliary events in cholecystectomized patients was lower (16% vs. 21.5%; P < 0.001), and cholecystectomized patients had a longer time to the occurrence of events (mean 74.49 [0.27] months vs. 73.50 [0.33] months; P = 0.03). There was no significant difference in the frequency of biliary events between elderly patients with and without cholecystectomy (P = 0.81), and the cumulative incidence of biliary events in the in situ group was significantly lower than that in the geriatric group (17.5% vs 32.6%; P = 0.03)
Conclusion: Although cholecystectomy significantly reduces subsequent biliary complications in young patients, it does not provide a statistically significant benefit in geriatric patients. We believe that there may be no need for routine prophylactic cholecystectomy after endoscopic sphincterotomy in geriatric patients.

Selective intraoperative cholangiography should be considered over routine intraoperative cholangiography during cholecystectomy: a systematic review and meta-analysis. Surg Endosc 2022; 36:7126-7139. [PMID: 35794500 PMCID: PMC9485186 DOI: 10.1007/s00464-022-09267-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2021] [Accepted: 04/09/2022] [Indexed: 11/29/2022]
Abstract
Background Decades of debate surround the use of intraoperative cholangiography (IOC) during cholecystectomy. To the present day, the role of IOC is controversial as regards decreasing the rate of bile duct injury (BDI). We aimed to review and analyse the available literature on the benefits of IOC during cholecystectomy. Methods A systematic literature search was performed until 19 October 2020 in five databases using the following search keys: cholangiogra* and cholecystectomy. The primary outcomes were BDI and retained stone rate. To investigate the differences between the groups (routine IOC vs selective IOC and IOC vs no IOC), we calculated weighted mean differences (WMD) for continuous outcomes and relative risks (RR) for dichotomous outcomes, with 95% confidence intervals (CI). Results Of the 19,863 articles, 38 were selected and 32 were included in the quantitative synthesis. Routine IOC showed no superiority compared to selective IOC in decreasing BDI (RR = 0.91, 95% CI 0.66; 1.24). Comparing IOC and no IOC, no statistically significant differences were found in the case of BDI, retained stone rate, readmission rate, and length of hospital stay. We found an increased risk of conversion rate to open surgery in the no IOC group (RR = 0.64, CI 0.51; 0.78). The operation time was significantly longer in the IOC group compared to the no IOC group (WMD = 11.25 min, 95% CI 6.57; 15.93). Conclusion Our findings suggest that IOC may not be indicated in every case, however, the evidence is very uncertain. Further good quality research is required to address this question.

Abstract
Background The purpose of this retrospective study aimed to assess the accuracy of detection of remnant common bile duct (CBD) stones by injecting saline through endoscopic nasobiliary drainage (ENBD) tubes under transabdominal ultrasound (US) guidance. Method Stone extraction and ENBD are regularly achieved through endoscopic retrograde cholangiopancreatography (ERCP) in patients with CBD stones. At 1–3 days thereafter, routine US studies were performed and repeated, using ENBD tubal saline injections (20–100 mL). Results A total of 302 patients underwent standard ERCP stone extractions in conjunction with occlusion cholangiograms, routine US testing, and ENBD-based saline-injection US exams. By occlusion cholangiogram, remnant stones were suspected in 31 (10.3%) patients in total of 302, and 26 (83.8%) were verified as true positives (sensitivity, 50.9%; specificity, 98.0%). Routine US studies proved suspicious in 13 (4.3%) patients in total of 302, and 12 (92.3%) were verified as true positives (sensitivity, 23.5%; specificity, 99.6%). Using ENBD-based saline-injection US, suspected stones were identified in 50 (16.6%) patients in total of 302, and 46 (92%) were verified as true positives (sensitivity, 90.1%; specificity, 98.4%). The sensitivity of ENBD-based saline-injection US significantly surpassed that of occlusion cholangiogram (p < 0.001) and routine US (p < 0.001). Conclusion Detection of remnant CBD stones via ENBD-based saline-injection US is a valid, inexpensive, and repeatable means of patient screening that is non-invasive, radiation-free, and dynamically informative. This may help improve the accuracy of detecting remnant CBD stones after ERCP. Supplementary Information The online version contains supplementary material available at 10.1186/s12876-022-02394-8.

Abstract
IMPORTANCE Gallbladder disease affects approximately 20 million people in the US. Acute cholecystitis is diagnosed in approximately 200 000 people in the US each year. OBSERVATIONS Gallstone-associated cystic duct obstruction is responsible for 90% to 95% of the cases of acute cholecystitis. Approximately 5% to 10% of patients with acute cholecystitis have acalculous cholecystitis, defined as acute inflammation of the gallbladder without gallstones, typically in the setting of severe critical illness. The typical presentation of acute cholecystitis consists of acute right upper quadrant pain, fever, and nausea that may be associated with eating and physical examination findings of right upper quadrant tenderness. Ultrasonography of the right upper quadrant has a sensitivity of approximately 81% and a specificity of approximately 83% for the diagnosis of acute cholecystitis. When an ultrasound result does not provide a definitive diagnosis, hepatobiliary scintigraphy (a nuclear medicine study that includes the intravenous injection of a radiotracer excreted in the bile) is the gold standard diagnostic test. Following diagnosis, early (performed within 1-3 days) vs late (performed after 3 days) laparoscopic cholecystectomy is associated with improved patient outcomes, including fewer composite postoperative complications (11.8% for early vs 34.4% for late), a shorter length of hospital stay (5.4 days vs 10.0 days), and lower hospital costs. During pregnancy, early laparoscopic cholecystectomy, compared with delayed operative management, is associated with a lower risk of maternal-fetal complications (1.6% for early vs 18.4% for delayed) and is recommended during all trimesters. In people older than 65 years of age, laparoscopic cholecystectomy is associated with lower mortality at 2-year follow-up (15.2%) compared with nonoperative management (29.3%). A percutaneous cholecystostomy tube, in which a drainage catheter is placed in the gallbladder lumen under image guidance, is an effective therapy for patients with an exceptionally high perioperative risk. However, percutaneous cholecystostomy tube placement in a randomized trial was associated with higher rates of postprocedural complications (65%) compared with laparoscopic cholecystectomy (12%). For patients with acalculous acute cholecystitis, percutaneous cholecystostomy tube should be reserved for patients who are severely ill at the time of diagnosis; all others should undergo a laparoscopic cholecystectomy. CONCLUSIONS AND RELEVANCE Acute cholecystitis, typically due to gallstone obstruction of the cystic duct, affects approximately 200 000 people in the US annually. In most patient populations, laparoscopic cholecystectomy, performed within 3 days of diagnosis, is the first-line therapy for acute cholecystitis.

Abstract
Gallstones affect 20% of the Western population and will grow in clinical significance as obesity and metabolic diseases become more prevalent. Gallbladder removal (cholecystectomy) is a common treatment for diseases caused by gallstones, with 1.2 million surgeries in the US each year, each costing USD 10,000. Gallbladder disease has a significant impact on the logistics and economics of healthcare. We discuss the two most common presentations of gallbladder disease (biliary colic and cholecystitis) and their pathophysiology, risk factors, signs and symptoms. We discuss the factors that affect clinical care, including diagnosis, treatment outcomes, surgical risk factors, quality of life and cost-efficacy. We highlight the importance of standardised guidelines and objective scoring systems in improving quality, consistency and compatibility across healthcare providers and in improving patient outcomes, collaborative opportunities and the cost-effectiveness of treatment. Guidelines and scoring only exist in select areas of the care pathway. Opportunities exist elsewhere in the care pathway.

Abstract
BACKGROUND Obtaining a clear Critical View of Safety helps prevent bile duct injuries during laparoscopic cholecystectomy, which can be improved with a structured Safe Critical View of Safety curriculum. We aimed to determine whether the improvement in obtaining Critical View of Safety postcurriculum is retained long-term. METHODS A safe Critical View of Safety curriculum was previously implemented for all surgeons who perform laparoscopic cholecystectomy at a regional health system. Recordings of laparoscopic cholecystectomy cases were collected 1 year after completion of the curriculum, deidentified and randomly ordered, and then graded by 2 blinded expert surgeons using a 6-point Critical View of Safety assessment tool. RESULTS A total of 12 surgeons with average experience of 17.9 ± 6.3 years in practice participated in the study. The majority (83%) had performed >700 laparoscopic cholecystectomies, and 4 surgeons (33%) reported 2 or more bile duct injuries in their career. Controlling for gallbladder pathology, Critical View of Safety scores improved from 1.7 ± 0.4 to 4.0 ± 0.4 (P < .001) immediately after completion of the curriculum. However, there was a small decrease in Critical View of Safety score after 1 year (3.2 ± 0.3 from 4.0 ± 0.4, P = .055), while still significantly higher compared to precurriculum (3.2 ± 0.3 vs 1.7 ± 0.4, P < .001). Acute care surgeons had lower Critical View of Safety retention scores compared to general surgeons (1.8 ± 0.5 vs 3.3 ± 0.4, P = .01) and minimally invasive surgeons (1.8 ± 0.5 vs 3.8 ± 0.5, P < .01). CONCLUSION A structured curriculum helped improve practicing surgeons' attainment of obtaining the Critical View of Safety during laparoscopic cholecystectomy. However, this improvement decreased after 1 year, suggesting some decay in knowledge retention over time. Therefore, continued educational interventions on Critical View of Safety and safe laparoscopic cholecystectomy may be needed to enhance long-term retention.

[PMID: 34724579 PMCID: PMC9160116 DOI: 10.1007/s00464-021-08838-8] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/10/2021] [Accepted: 10/21/2021] [Indexed: 12/07/2022]
Abstract
Background T-tube drainage after laparoscopic common bile duct exploration (LCBDE) has been demonstrated to be safe and effective for patients with acute cholangitis caused by common bile duct stones (CBDSs). The outcomes after LCBDE with primary closure in patients with CBDS-related acute cholangitis are unknown. The present study aimed to evaluate the efficacy and safety of LCBDE with primary closure for the management of acute cholangitis caused by CBDSs. Methods Between June 2015 and June 2020, 368 consecutive patients with choledocholithiasis combined with cholecystolithiasis, who underwent laparoscopic cholecystectomy (LC) + LCBDE in our department, were retrospectively reviewed. A total of 193 patients with CBDS-related acute cholangitis underwent LC + LCBDE with primary closure of the CBD (PC group) and 62 patients underwent LC + LCBDE followed by T-tube placement (T-tube group). A total of 113 patients who did not have cholangitis were excluded. The clinical data were compared and analyzed. Results There was no mortality in either group. No significant differences were noted in morbidity, bile leakage rate, retained CBD stones, or readmission rate within 30 days between the two groups. Compared with the T-tube group, the PC group avoided T-tube-related complications and had a shorter operative time (121.12 min vs. 143.37 min) and length of postoperative hospital stay (6.59 days vs. 8.81 days). Moreover, the hospital expenses in the PC group were significantly lower than those in the T-tube group ($4844.47 vs. $5717.22). No biliary stricture occurred during a median follow-up of 18 months in any patient. No significant difference between the two groups was observed in the rate of stone recurrence. Conclusions LCBDE with primary closure is a safe and effective treatment for cholangitis caused by CBDSs. LCBDE with primary closure is not inferior to T-tube drainage for the management of CBDS-related acute cholangitis in suitable patients.

Evaluation of factors predicting loss of benefit provided by laparoscopic distal pancreatectomy compared to open approach. Updates Surg 2021; 74:213-221. [PMID: 34687429 DOI: 10.1007/s13304-021-01194-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2021] [Accepted: 10/12/2021] [Indexed: 10/20/2022]
Abstract
Several studies showed safety and feasibility of laparoscopic distal pancreatectomy (LDP) as compared to open distal pancreatectomy (ODP). Patients who underwent LDP or ODP (2015-2019) were included. A 1:1 propensity score matching (PSM) was used to reduce the effect of treatment selection bias. Aim of this study was to identify those factors influencing the loss of benefit (defined as a significantly better outcome compared to ODP) after LDP. Overall, 387 patients underwent DP (n = 250 LDP, n = 137 ODP). After PSM, 274 patients (n = 137 LDP, n = 137 ODP) were selected. LDP was associated with reduced intraoperative blood loss (median: 200 mL vs. 250 mL, p < 0.001), decreased wound infection rate (1% vs. 9%, p = 0.044) and shorter time to functional recovery (TFR) (median: 4 days vs. 5 days, p = 0.002). Consequently, TFR > 5 days and blood loss > 250 mL were defined as loss of benefit after LDP. In the LDP group, age > 70 years [Odds Ratio (OR) 2.744, p = 0.022] and duration of surgery > 208 min (OR 2.957, p = 0.019) were predictors of TFR > 5 days and intraoperative blood loss > 250 mL, respectively. No differences in terms of TFR were found between ODP and LDP groups in patients > 70 years (p = 0.102). Intraoperative blood loss was significantly higher in the ODP group, also when the analysis was limited to surgical procedures with operative time > 208 min (p = 0.003). In conclusion, LDP seems comparable to ODP in terms of TFR in patients aged > 70 years. This finding could be helpful in the choice of the best surgical approach in elderly patients undergoing potentially challenging DPs.

Abstract
Importance There is currently no consensus on the indication for cholecystectomy in patients with uncomplicated gallstone disease. Objective To report on the development and validation of a multivariable prediction model to better select patients for surgery. Design, Setting, and Participants This study evaluates data from 2 multicenter prospective trials (the previously published Scrutinizing (In)efficient Use of Cholecystectomy: A Randomized Trial Concerning Variation in Practice [SECURE] and the Standardized Work-up for Symptomatic Cholecystolithiasis [Success] trial) collected from the outpatient clinics of 25 Dutch hospitals between April 2014 and June 2019 and including 1561 patients with symptomatic uncomplicated cholelithiasis, defined as gallstone disease without signs of complicated cholelithiasis (ie, biliary pancreatitis, cholangitis, common bile duct stones or cholecystitis). Data were analyzed from January 2020 to June 2020. Exposures Patient characteristics, comorbidity, surgical outcomes, pain, and symptoms measured at baseline and at 6 months' follow-up. Main Outcomes and Measures A multivariable regression model to predict a pain-free state or a clinically relevant reduction in pain after surgery. Model performance was evaluated using calibration and discrimination. Results A total of 1561 patients were included (494 patients in 7 hospitals in the development cohort and 1067 patients in 24 hospitals in the validation cohort; 6 hospitals included patients in both cohorts). In the development cohort, 395 patients (80.0%) underwent cholecystectomy. After surgery, 225 patients (57.0%) reported that they were pain free and 295 (74.7%) reported a clinically relevant reduction in pain. A multivariable prediction model showed that increased age, no history of abdominal surgery, increased visual analog scale pain score at baseline, pain radiation to the back, pain reduction with simple analgesics, nausea, and no heartburn were independent predictors of clinically relevant pain reduction after cholecystectomy. After internal validation, good discrimination was found (C statistic, 0.80; 95% CI, 0.74-0.84) between patients with and without clinically relevant pain reduction. The model had very good overall calibration and minimal underestimation of the probability. External validation indicated a good discrimination between patients with and without clinically relevant pain reduction (C statistic, 0.74; 95% CI, 0.70-0.78) and fair calibration with some overestimation of probability by the model. Conclusions and Relevance The model validated in this study may help predict the probability of pain reduction after cholecystectomy and thus aid surgeons in deciding whether patients with uncomplicated cholelithiasis will benefit from cholecystectomy.

Laparoscopic cholecystectomy for left-sided gallbladder. Langenbecks Arch Surg 2021; 407:207-212. [PMID: 34240246 DOI: 10.1007/s00423-021-02263-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/16/2020] [Accepted: 06/30/2021] [Indexed: 12/07/2022]
Abstract
PURPOSE Left-sided gallbladder (LSGB) is a rare congenital anomaly in the gallbladder, which is defined as a gallbladder located on the left side of the falciform ligament without situs inversus. We retrospectively analyzed 13 patients diagnosed with LSGB in a single center to confirm the safety of laparoscopic cholecystectomy (LC) and reviewed the anatomical implications in those patients. METHODS Of the 4910 patients who underwent LC for the treatment of gallbladder disease between August 2007 and December 2019, 13 (0.26%) were diagnosed as having LSGB. We retrospectively analyzed these 13 patients for general characteristics, perioperative outcomes, and other variations through the perioperative imaging workups. RESULTS All patients underwent LC for gallbladder disease. In all cases, the gallbladder was located on the left side of the falciform ligament. The operation was successfully performed with standard four-trocar technique, confirming "critical view of safety (CVS)" as usual without two cases (15.4%). In one case, which had an intraoperative complication and needed choledochojejunostomy because of common bile duct injury, there was an associated variation with early common bile duct bifurcation. The other patient underwent an open conversion technique because of severe fibrosis in the Calot's triangle. Furthermore, on postoperative computed tomography, abnormal intrahepatic portal venous branching was found in all cases. CONCLUSIONS Although LSGB is usually encountered by chance during surgery, it can be successfully managed through LC with CVS. However, surgeons who find LSGB have to make efforts to be aware of the high risk of bile duct injury and possibility of associated anomalies.

MRI evaluation of bile duct injuries and other post-cholecystectomy complications. Abdom Radiol (NY) 2021; 46:3086-3104. [PMID: 33576868 DOI: 10.1007/s00261-020-02947-z] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2020] [Revised: 12/23/2020] [Accepted: 12/31/2020] [Indexed: 12/14/2022]
Abstract
Laparoscopic cholecystectomy is one of the most common procedures performed each year and can be associated with various post-operative complications. Imaging is integral to diagnosis and management of patients with suspected cholecystectomy complications, and a thorough understanding of normal and abnormal biliary anatomy, risk factors for biliary injury, and the spectrum of adverse events is crucial for interpretation of imaging studies. Magnetic resonance cholangiography (MRC) enhanced with hepatobiliary contrast agent is useful in delineating biliary anatomy and pathology following cholecystectomy. In this article, we provide a protocol for contrast-enhanced MR imaging of the biliary tree. We also review the classification and imaging manifestations of post-cholecystectomy bile duct injuries in addition to other complications such as bilomas, retained/dropped gallstones, and vascular injuries.

Scoring system for gallbladder polyps based on the cross-sectional area and patient characteristics. Asian J Surg 2021; 45:332-338. [PMID: 34147329 DOI: 10.1016/j.asjsur.2021.05.048] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2021] [Revised: 05/14/2021] [Accepted: 05/31/2021] [Indexed: 11/02/2022] Open
Abstract
BACKGROUND Current management guidelines for gallbladder polyps (GBPs) focus on a diameter more than 1 cm as an indication for cholecystectomy. Since most GBPs are not malignant, unnecessary cholecystectomies can lead to unnecessary complications and costs. We developed a score to identify true polyps focusing on their cross-sectional area (CSA). METHODS We retrospectively analyzed the demographic, clinical, laboratory, and sonographic characteristics of 522 patients with GBPs who had undergone cholecystectomy at our hospital between January 2010 and July 2020 (reference group). We used univariate analysis to compare these parameters between 88 true polyps and 434 pseudopolyps and multivariate logistic regression analysis to identify parameters to include in our scoring model. Receiver operating characteristics and area under the curve were used to identify cut-off values. The model was tested on a validation group of 98 patients. RESULTS In the multivariate analysis, a CSA >123 mm2, positive blood flow signal, age >55.5 years, alanine aminotransferase (ALT) levels > 50 U/L, and an ALT/aspartate aminotransferase ratio > 0.77 were significantly associated with true polyps (odds ratio 6.528, 2.377, 2.617, 2.445, and -0.372, respectively). A prediction model based on cut-off values was used to distinguish a low-risk and high-risk GBP group; true polyps accounted for 6.54% and 58.72%, respectively (p < 0.001). In the low-risk and high-risk validation groups, true polyps comprised 12.35% and 82.35%, respectively (p < 0.001). CONCLUSIONS Our scoring system shows high accuracy and specificity in identifying true polyps and helps determine the need for surgical resection.

2020 WSES guidelines for the detection and management of bile duct injury during cholecystectomy. World J Emerg Surg 2021; 16:30. [PMID: 34112197 PMCID: PMC8190978 DOI: 10.1186/s13017-021-00369-w] [Citation(s) in RCA: 49] [Impact Index Per Article: 16.3] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2021] [Accepted: 05/18/2021] [Indexed: 12/16/2022] Open
Abstract
Bile duct injury (BDI) is a dangerous complication of cholecystectomy, with significant postoperative sequelae for the patient in terms of morbidity, mortality, and long-term quality of life. BDIs have an estimated incidence of 0.4-1.5%, but considering the number of cholecystectomies performed worldwide, mostly by laparoscopy, surgeons must be prepared to manage this surgical challenge. Most BDIs are recognized either during the procedure or in the immediate postoperative period. However, some BDIs may be discovered later during the postoperative period, and this may translate to delayed or inappropriate treatments. Providing a specific diagnosis and a precise description of the BDI will expedite the decision-making process and increase the chance of treatment success. Subsequently, the choice and timing of the appropriate reconstructive strategy have a critical role in long-term prognosis. Currently, a wide spectrum of multidisciplinary interventions with different degrees of invasiveness is indicated for BDI management. These World Society of Emergency Surgery (WSES) guidelines have been produced following an exhaustive review of the current literature and an international expert panel discussion with the aim of providing evidence-based recommendations to facilitate and standardize the detection and management of BDIs during cholecystectomy. In particular, the 2020 WSES guidelines cover the following key aspects: (1) strategies to minimize the risk of BDI during cholecystectomy; (2) BDI rates in general surgery units and review of surgical practice; (3) how to classify, stage, and report BDI once detected; (4) how to manage an intraoperatively detected BDI; (5) indications for antibiotic treatment; (6) indications for clinical, biochemical, and imaging investigations for suspected BDI; and (7) how to manage a postoperatively detected BDI.

Umbilical port versus epigastric port for gallbladder extraction in laparoscopic cholecystectomy: A systematic review and meta-analysis of randomized controlled trials with trial sequential analysis. Surgeon 2021; 20:e26-e35. [PMID: 33888427 DOI: 10.1016/j.surge.2021.02.009] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2020] [Revised: 12/04/2020] [Accepted: 02/15/2021] [Indexed: 01/11/2023]
Abstract
BACKGROUND After laparoscopic cholecystectomy, gallbladder can be extracted either from epigastric/subxiphoid port or umbilical port. We conducted systematic review of randomized controlled trials comparing the two. METHODS PRISMA-compliant systematic review and meta-analysis was conducted with pre-specified study protocol registered on PROSPERO (CRD42019128662). Multiple databases were searched from inception till 14 September 2019 using search terms "gallbladder", "specimen", "extraction', "extract", "cholecystectomy", "epigastric port", "subxiphoid port" "umbilical port". Outcomes assessed were postoperative pain (visual analog scale at 24 h postoperatively), port-site hernia, port-site infection, operative time and gallbladder retrieval time. Data were analyzed using random-effects models with risk ratios (RR) for dichotomous variables and mean difference (MD) for continuous variables. RESULTS Of 280 articles retrieved, 9 RCT's with 1036 participants were included. Quality of included studies was judged to be "moderate" to "low". There was no difference in postoperative pain at 24 h (p = 0.76), total operative time (p = 0.11), gallbladder retrieval time (p = 0.72) or surgical site infection (p = 0.93). Umbilical port retrieval was associated with significantly higher risk of port-site herniae (RR 2.68, 95%CI:1.06-6.80, p = 0.04). After sensitivity analysis, operative time was significantly shorter with epigastric retrieval (p = 0.0007). Trial sequential analysis showed that current studies were successful in achieving optimum information size for primary outcome. CONCLUSIONS There was no difference in postoperative pain and infections between umbilical and epigastric port retrieval. Umbilical port retrieval was associated with significantly higher risk of developing port-site hernia and could also be associated with longer operative time. Epigastric port may be favorable for gallbladder retrieval in multiport laparoscopic cholecystectomy.

One-stage fluoroscopy-guided laparoscopic transcystic papillary balloon dilation and laparoscopic cholecystectomy in patients with cholecystocholedocholithiasis who previously had undergone gastrectomy for gastric cancer. Asian J Endosc Surg 2021; 14:193-199. [PMID: 32790037 PMCID: PMC8048915 DOI: 10.1111/ases.12845] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/08/2020] [Revised: 06/30/2020] [Accepted: 07/01/2020] [Indexed: 12/23/2022]
Abstract
BACKGROUND Patients with a history of gastrectomy have a higher incidence of cholecystocholedocholithiasis (CCL) and related morbidities than the general population. However, the management of common bile duct (CBD) stones with endoscopic retrograde cholangiopancreatography is challenging in patients after Roux-en-Y or Billroth II reconstruction because of the altered gastrointestinal anatomy. The aim of the current study was to evaluate the safety and efficacy of one-stage laparoscopic transcystic papillary balloon dilation and laparoscopic cholecystectomy (LTPBD+LC) in patients with previous gastrectomy for gastric cancer. METHODS This retrospective cohort study included five patients with CCL who had previously undergone gastrectomy. All five underwent LTPBD+LC between May 2015 and February 2020 at our institution. The primary end-point was complete clearance of the CBD stones. RESULTS Of the 311 patients who had undergone gastrectomy for gastric cancer from December 2009 to December 2018 at our institution, six (1.9%) were later diagnosed with CCL. Five of the six patients did not need emergency biliary drainage and underwent conservative therapy and subsequent elective LTPBD+LC. LTPBD+LC was successfully performed in all cases. None of the patients required conversion to open surgery. The rate of complete clearance of the CBD stones was 100%. The mean operative time of the entire procedure was 126 minutes (range, 102-144 minutes), and the mean blood loss was 12.4 mL (range, 1-50 mL). There were no major perioperative complications, and the mean length of postoperative hospital stay was 4.2 days (range, 3-7 days). CONCLUSION One-stage LTPBD+LC may be a feasible procedure for patients with CCL who have previously undergone gastrectomy for gastric cancer.

Healthcare Disparities in the Management of Acute Cholecystitis: Impact of Race, Gender, and Socioeconomic Factors on Cholecystectomy vs Percutaneous Cholecystostomy. J Gastrointest Surg 2021; 25:880-886. [PMID: 33629232 DOI: 10.1007/s11605-021-04959-6] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/23/2020] [Accepted: 02/08/2021] [Indexed: 01/31/2023]
Abstract
BACKGROUND While percutaneous cholecystostomy (PC) is a recommended treatment strategy in lieu of cholecystectomy (CCY) for acute cholecystitis among patients who may not be considered good surgical candidates, reports on disparities in treatment utilization remain limited. The aim of this study was to investigate the role of demographic, clinical, and socioeconomic factors in treatment of acute cholecystitis. METHODS Patients with a diagnosis of acute cholecystitis who underwent CCY versus PC were reviewed from the U.S. Nationwide Inpatient Sample (NIS) database between 2008-2014. Measured variables including age, race/ethnicity, Charlson comorbidity index (CCI), hospital type/region, insurance payer, household income, length of stay (LOS), hospital cost, and mortality were compared using chi-square and ANOVA. Multivariable logistic regression was performed to identify specific predictors of cholecystitis treatment. RESULTS A total of 1,492,877 patients (CCY:n=1,435,255 versus PC:n=57,622) were analyzed. The majority of patients that received PC were at urban teaching hospitals (65.2%). LOS was significantly longer with higher associated costs for PC [(11.1±11.0 versus 4.5±5.3 days; P<0.001) and ($99577±138850 versus $48399±58330; P<0.001)]. Mortality was also increased for patients that received PC compared to CCY (8.8% versus 0.6%; P<0.001). Multivariable regression demonstrated multiple socioeconomic and healthcare-related factors influencing the utilization of PC including male gender, Black or Asian race/ethnicity, Medicare payer status, urban hospital location, and household income (all P<0.001). CONCLUSION Although patients receiving PC had higher CCI scores, multiple socioeconomic and healthcare related factors appeared to also influence this treatment decision. Additional studies to investigate these disparities are indicated to improve outcomes for all individuals with this condition.
