Transumbilical laparoscopy for pneumoperitoneum establishment: a comprehensive multicentre evaluation affirming safety, feasibility, and a range of clinical benefits. Front Surg 2024; 11:1390038. [PMID: 38712337 PMCID: PMC11070471 DOI: 10.3389/fsurg.2024.1390038] [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] [Received: 02/22/2024] [Accepted: 04/08/2024] [Indexed: 05/08/2024] Open
Abstract
Introduction Transumbilical laparoscopy (TUL) has emerged as a promising technique for establishing pneumoperitoneum in laparoscopic cholecystectomy, offering potential safety, feasibility, and clinical benefits. This retrospective multicentre study aims to evaluate the efficacy and outcomes of TUL in the management of gallbladder diseases. Methods A retrospective analysis was conducted on a cohort of 2,543 patients who underwent TUL between 2011 and 2021 across various medical institutions in Italy. Data collection included demographic, clinical, intraoperative, and postoperative parameters. Standardized protocols were followed for preoperative and postoperative management. The TUL technique involved precise anatomical incision and trocar placement. Results The study demonstrated favorable outcomes associated with TUL, including a low conversion rate to open surgery (0.55%), minimal intraoperative complications (0.16%), and short hospital stays (average 2.4 days). The incidence of incisional hernias was notably low (0.4%). Comparison with existing literature revealed consistent findings and provided unique insights into the advantages of TUL. Discussion Despite limitations, such as the absence of a control group and the retrospective nature of the study, the findings contribute valuable insights to the literature. They inform surgical decision-making and advance patient care in laparoscopic cholecystectomy for gallbladder diseases. Conclusion Transumbilical laparoscopy shows promise as a safe and feasible technique for establishing pneumoperitoneum in laparoscopic cholecystectomy. The study's findings support its clinical benefits, including low conversion rates, minimal complications, and short hospital stays. Further research, including prospective studies with control groups, is warranted to validate these results and optimize patient outcomes.

Advancing laparoscopy in resource-limited settings. BMC Surg 2024; 24:98. [PMID: 38532330 DOI: 10.1186/s12893-024-02387-2] [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: 11/22/2023] [Accepted: 03/12/2024] [Indexed: 03/28/2024] Open
Abstract
BACKGROUND Although laparoscopic surgery has made remarkable progress and become the standard approach for various surgical procedures worldwide over the past 30 years, its establishment in low-resource settings, particularly in public hospitals, has been challenging. The lack of equipment and trained expertise has hindered its widespread adoption in these settings. Cholecystectomy is one of the most commonly performed procedures using laparoscopy world wide AIM: The aim of the study is to determine whether laparoscopic cholecystectomy is feasible in a resource challenged setting METHODS: The research focused on individuals who underwent laparoscopic or open cholecystectomies at Yekatit 12 Hospital in Addis Ababa, Ethiopia, over a one-year period. Comprehensive data collection was conducted prospectively, encompassing both intraoperative and postoperative parameters. Follow-up was carried out via phone calls. The surgical procedures employed innovative techniques, including the reuse of sterilized single-use equipment and the utilization of local resources. The evaluation involved a comparison of demographic information, intraoperative details (such as critical view determination and operative duration), and postoperative complications, including assessments of pain and wound infections RESULTS: From August 2021 to September 2022, 119 patients were assessed. Among these patients, 65 (54.6%) underwent open cholecystectomies, while the remaining 54 (45.4%) underwent laparoscopic cholecystectomies. The average duration of the laparoscopic cholecystectomies was 90.7 min, which is 17.7 min behind the open. Patients in the laparoscopy group had significantly shorter hospital stays than the open group, and 94% were discharged by post operative day 2. The conversion rate from laparoscopic to open surgery was determined to be 3.3% CONCLUSION: To sum up, the safe execution of laparoscopic cholecystectomies is feasible in public hospitals and settings with limited resources, given adequate training and resource distribution. The study findings showcased superior outcomes, including reduced hospitalization duration and fewer complications, while maintaining comparable levels of operative duration and patient satisfaction in both groups.

Abstract
Background/Objective This study aims to develop an objective marker that predicts the risk of conversion from laparoscopy to open surgery using gallbladder wall thickness and inflammatory index values. Materials and Methods A total of 2,920 cholecystectomy patients were screened, including those whose operations were converted to open and those who underwent laparoscopy. A total of 700 cholecystectomy patients who met the study criteria were included in the study. The same team of surgeons performed all operations. The conversion probability from laparoscopic to open cholecystectomy was calculated using the ratio obtained by evaluating inflammatory markers and gallbladder wall thickness (K). The preoperative complete blood count and abdominal ultrasound data of the patients were obtained from our university patient registry system. Results Age, neutrophil count, gallbladder wall thickness, neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), KxNLR, and KxPLR values were all significantly higher in the conversion from laparoscopy to open surgery group compared with the laparoscopic cholecystectomy group. According to the ROC analysis performed on the gallbladder wall thickness values according to the probability of conversion to open surgery, the cutoff value was determined as >3 mm. Gallbladder wall thickness >KxPLR >KxNLR was defined as the diagnostic value order according to the area under the curve. Conclusions The results of this study showed that gallbladder wall thickness effectively determines the probability of conversion from laparoscopy to open cholecystectomy and multiplying the gallbladder wall thickness (mm) by NLR increased the sensitivity.

Risk Factors and Prevalence Associated With Conversion of Laparoscopic Cholecystectomy to Open Cholecystectomy: A Tertiary Care Hospital Experience in Western Mexico. Cureus 2023; 15:e45720. [PMID: 37868578 PMCID: PMC10590211 DOI: 10.7759/cureus.45720] [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: 09/20/2023] [Indexed: 10/24/2023] Open
Abstract
Introduction Laparoscopic cholecystectomy (LC) is a common procedure used for the treatment of different pathologies caused by gallstones in the gallbladder, and one of the most common indications is acute cholecystitis. The definitive treatment for acute cholecystitis is surgery, and LC is the gold standard. Nevertheless, transoperative complications (like intraoperative bleeding, anatomical abnormalities of the gallbladder, etc.) of LC and some other preoperative factors (like dilatation of bile duct, increased gallbladder wall thickness, etc.) can cause or be a risk factor for conversion to open cholecystectomy (OC). The objective of this study was to determine the risk factors and prevalence associated with the conversion from LC to OC in patients with gallbladder pathology and the indication for LC. Materials and methods This was a prospective cohort study. We included patients of both sexes over 18 years of age with gallbladder disease. To determine the risk factors associated with conversion, we performed a bivariate analysis and then a multivariate analysis. Results The rate of conversion to OC was 4.54%. The preoperative factors associated with conversion, in the bivariate analysis, were common bile duct dilatation (p=0.008), emergency surgery (p=0.014), and smoking (p=0.001); the associated intraoperative variables were: laparoscopic surgery duration (p <0.0001), Calot triangle edema (p=0.033), incapacity to hold the gallbladder with atraumatic laparoscopic tweezers (p=0.036), and choledocholithiasis (p=0.042). Laparoscopic Surgery duration was the only factor with a significant association in the multivariate analysis (p=0.0036); we performed a receiver operating characteristic (ROC) curve analysis and found a cut-off point of 120 minutes for the duration of laparoscopic surgery with a sensitivity and a specificity of 67 and 88%, respectively. Conclusion The prevalence of conversion from LC to OC is similar to that reported in the international literature. The risk factors associated with conversion to OC, in this study, should be confirmed in future clinical studies, in this same population, with a larger sample size.

Are outcomes for emergency index-admission laparoscopic cholecystectomy performed by hepatopancreatobiliary surgeons better compared to non-hepatopancreatobiliary surgeons? A 10-year audit using 1:1 propensity score matching. Hepatobiliary Pancreat Dis Int 2023:S1499-3872(23)00121-2. [PMID: 37586993 DOI: 10.1016/j.hbpd.2023.08.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/18/2023] [Accepted: 08/02/2023] [Indexed: 08/18/2023]
Abstract
BACKGROUND Emergency index-admission cholecystectomy (EIC) is recommended for acute cholecystitis in most cases. General surgeons have less exposure in managing "difficult" cholecystectomies. This study aimed to compare the outcomes of EIC between hepatopancreatobiliary (HPB) versus non-HPB surgeons. METHODS This is a 10-year retrospective audit on patients who underwent EIC from December 2011 to March 2022. Patients who underwent open cholecystectomy, had previous cholecystitis, previous endoscopic retrograde cholangiopancreatography or cholecystostomy were excluded. A 1:1 propensity score matching (PSM) was performed to adjust for confounding variables (e.g. age ≥ 75 years, history of abdominal surgery, presence of dense adhesions). RESULTS There were 1409 patients (684 HPB cases, 725 non-HPB cases) in the unmatched cohort. Majority (52.3%) of them were males with a mean age of 59.2 ± 14.9 years. Among 472 (33.5%) patients with EIC performed ≥ 72 hours after presentation, 40.1% had dense adhesion. The incidence of any morbidity, open conversion, subtotal cholecystectomy and bile duct injury were 12.4%, 5.0%, 14.6% and 0.1%, respectively. There was one mortality within 30 days from EIC. PSM resulted in 1166 patients (583 per group). Operative time was shorter when EIC was performed by HPB surgeons (115.5 min vs. 133.4 min, P < 0.001). The mean length of hospital stay was comparable. EIC performed by HPB surgeons was independently associated with lower open conversion [odds ratio (OR)= 0.24, 95% confidence interval (CI): 0.12-0.49, P < 0.001], lower fundus-first cholecystectomy (OR= 0.58, 95% CI: 0.35-0.95, P= 0.032), but higher subtotal cholecystectomy (OR= 4.19, 95% CI: 2.24-7.84, P < 0.001). Any morbidity, bile duct injury and mortality were comparable between the two groups. CONCLUSION EIC performed by HPB surgeons were associated with shorter operative time and reduced risk of open conversion. However, the incidence of subtotal cholecystectomy was higher.

A Study of the Degree of Gall Bladder Wall Thickness and Its Impact on Patients Undergoing Laparoscopic Cholecystectomy. Cureus 2023; 15:e38990. [PMID: 37323346 PMCID: PMC10261991 DOI: 10.7759/cureus.38990] [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: 05/14/2023] [Indexed: 06/17/2023] Open
Abstract
Background The gold standard management for symptomatic gallstone disease is elective laparoscopic cholecystectomy, which has replaced open cholecystectomy. The wall thickness of the gallbladder is an indicator of cholecystitis in patients who have presented with symptoms of gallstone disease. The aim of this study was to evaluate preoperative gall bladder wall thickness by ultrasonography and assess its impact on the outcome of laparoscopic cholecystectomy, including conversion rate, complications, operative time, and postoperative hospital stay. Method This prospective study was conducted on 350 patients with symptomatic gallstone disease, those who had undergone laparoscopic cholecystectomy in Dr. Sampurnanand Medical College, Jodhpur, and attached hospitals from July 2019 to November 2021. On the basis of ultrasonography findings of gallbladder wall thickness, patients were divided into four groups: normal thickness - up to 2 mm, mild thickness - 3-4mm, moderate thickness - 5-6mm, and severe wall thickness - more than 6mm). Up to 2 millimeters thickness was considered as normal. Results The incidence of conversion rate, as well as intra or postoperative complications, were higher in moderate and severe wall thickness groups. The maximum incidence of complication rate is seen in moderately thickened group (33.33%). In severely thickened group, complication was seen in 100% of patients. Operative time, as well as postoperative hospital stay, were more in higher thickness groups. There was a statistically significant correlation between gallbladder wall thickness and conversion rate, complications operative time, and postoperative length of stay. Conclusion Increased gallbladder wall thickness causes increased intra as well as postoperative complications, more conversion to open procedure rate, increased operative time, and enhanced postoperative hospital stay. Among the total study population, 29.71% of patients had increased gallbladder wall thickness. In our study, a positive correlation was seen among gallbladder wall thickness, complication rate, conversion rate, intraoperative time, and postoperative hospital stay.

Current status of laparoscopic surgery usage in Türkiye: A middle-income country. Turk J Surg 2022; 38:353-361. [PMID: 36875273 PMCID: PMC9979558 DOI: 10.47717/turkjsurg.2022.5713] [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: 03/13/2022] [Accepted: 08/31/2022] [Indexed: 01/12/2023]
Abstract
Objectives This study aimed to determine the usage status of laparoscopic procedures in general surgical practice in Türkiye, which is a sample of middle-income countries. Material and Methods The questionnaire was sent to general surgeons, gastrointestinal surgeons, and surgical oncologists who have completed their residency training and are actively working in university, public or private hospitals. Demographic data, laparoscopy training and the period of education, the rate of laparoscopy use, the type and volume of laparoscopic surgical procedures, their views on the advantages and disadvantages of laparoscopic surgery, and the reasons for preferring laparoscopy were determined with a 30-item questionnaire. Results Two hundred and forty-four questionnaires from 55 different cities of Türkiye were evaluated. The responders were mainly males, younger surgeons (F/M= 11.1/88.9 % and 30-39 y/o), and graduated from the university hospital residence program (56.6%). Laparoscopic training was frequently taken during residency (77.5%) in the younger age group, while the elderly participants mostly received additional training after specialization (91.7%). Laparoscopic surgery was mostly not available in public hospitals for advanced procedures (p <0.0001) but was available for cholecystectomy and appendectomy operations (p= NS). However, participants working in university hospitals mostly stated that the laparoscopic approach was the first choice for advanced procedures. Conclusion The results of this study showed that the surgeons working in MICs spent strong effort to use laparoscopy in daily practice, especially in university and high-volume hospitals. However, inappropriate education, cost of laparoscopic equipment, healthcare policies, and some cultural and social barriers might have negatively impacted the widespread use of laparoscopic surgery and its usage in daily practice in MICs such as Türkiye.

Abstract
BACKGROUND The conversion to open surgery (COS) during the Laparoscopic Cholecystectomy (LC) is reported to occur at a rate of 10-15%. Some preoperative risk factors (RF) have been postulated; however, few studies have evaluated these factors and the intraoperative complexity with the COS rate. The aim of the study was to evaluate the preoperative RF and intraoperative complexity using the Parkland grading scale (PGS) with the COS rate in LC. METHODS A retrospective study was done evaluating the demographic and surgical variables from the patients and LC videos from 8 different hospitals of Mexico City from December 2018 to January 2020. The evaluation of the PGS was done by 2 surgeons (one MI and one HPB surgeon); the PGS was also categorized as Non-Complex LC (nCLC, PGS1-2) and Complex LC (CLC, PGS 3-5). Logistic regression was used to evaluate the association of this factors with the COS rate. RESULTS 430 LC were analyzed; 358 (78.61%) were women, 261 (60.7%) were elective and 169(39.3%) urgent LC, the mean age was 44.06 (SD ± 13.16) years. 21 (4.8%) LC were COS; the mean age of this group was 55 (SD ± 12.95), 3 (0.7%) were nCLC and 18 (4.19%) CLC, mean PGS of 3.76 (SD ± 1.09), the mean time to COS was 48.67 (SD ± 41.9), the estimated blood loss (EBL) was 258 (SD ± 260.22) and 6 (1.4%) intraoperative BDI were recognized on this group. Univariate analysis showed a significant association with the COS with male sex, older age, age > 45 years, presence of comorbidities, a higher PGS, a CLC, higher EBL and possible BDI; multivariate analysis produced a model using male sex, age, presence of comorbidities and a CLC with a 0.809 area under the ROC curve. CONCLUSION The recognition of the associated RF and a CLC can guide the surgeon to establish preoperative and bailout strategies during the procedure, recognizing a higher risk of COS and its higher morbidity.

Abstract
OBJECTIVE The aim of this study was to examine real-life patterns of care and patient outcomes associated with robot-assisted cholecystectomy (RAC) in New York State (NYS). BACKGROUND Although robotic assistance may offer some technological advantages, RACs are associated with higher procedural costs and longer operating times compared to traditional laparoscopic cholecystectomies (LCs). Evidence on long-term patient outcomes after RAC from large population-based datasets remains limited and inconsistent. METHODS Using NYS inpatient and ambulatory surgery data from the Statewide Planning and Research Cooperative System (2009-2017), we conducted bivariate and multivariate analyses to examine patterns of utilization, complications, and secondary procedures following cholecystectomies. RESULTS Among 299,306 minimally invasive cholecystectomies performed in NYS between 2009 and 2017, one thousand one hundred eighteen (0.4%) were robot-assisted. Compared to those undergoing LC, RAC patients were older, travelled further for surgery, and were more likely to have public insurance and preoperative comorbidities. RAC versus LC patients were more significantly likely to have conversions to open procedure (4.9% vs 2.8%), bile duct injuries (1.3% vs 0.4%), and major reconstructive interventions (0.6% vs 0.1%), longer median length of stay (3 vs 1 day), readmissions (7.3% vs 4.4%), and higher 12-month post-index surgery hospital charges (P < 0.01 for all estimates). Other postoperative complications decreased over time for LC but remained unchanged for RAC patients. CONCLUSIONS Patients receiving RAC in NYS experienced higher rates of complications compared to LC patients. Addressing patient-, surgeon-, and system-level factors associated with intra/postoperative complications and applying recently promulgated safe cholecystectomy strategies coupled with advanced imaging modalities like fluorescence cholangiography to RAC may improve patient outcomes.

Abstract
Background: The contracted gallbladder may predispose to a higher rate of biliary or vasculobiliary injury (VBI). It is usually associated with unclear anatomy due to chronic inflammation and fibrosis in the hepatoduodenal ligament region. Laparoscopic ultrasound (LUS) can very effectively delineate anatomical conditions during cholecystectomy. Our study aimed to compare the visual and ultrasonographic navigation around the shrunken gallbladder. Materials and Methods: The study group consisted of 612 patients qualified for laparoscopic cholecystectomy. The shrunken gallbladder was diagnosed intraoperatively in 13 patients (2.1%). In 6 patients, the only intraoperative navigation method was a visual evaluation of anatomical conditions, and in 7 patients, the method was LUS. Results: The operating time and the length of hospital stay after surgery were significantly lower, the number of conversions was insignificantly lower, and the number of successful visualization of anatomical conditions was significantly higher in the LUS group. We did not observe any bile duct and VBI in patients with the shrunken gallbladder. Conclusions: The combination of the fundus-first and subtotal cholecystectomy with LUS navigation might be an effective proposal when coming across the shrunken gallbladder.

Abstract
Acute severe colitis is the major indication for surgery in inflammatory bowel diseases (IBD), and in particular, in ulcerative colitis (UC). A laparoscopic approach for abdominal colectomy is recommended, due to better perioperative and long-term outcomes. However, costs, time-spending, and outcomes are still a topic of improvement. We designed a standardized 10-steps, sequential approach to laparoscopic colectomy, based on the philosophy of the “critical view of safety”, with the aim to improve perioperative outcomes (operative duration, estimated blood loss, complications, readmissions, reoperations, and length of postoperative stay). We performed a retrospective cohort study using data from a prospectively maintained clinical database. We included all the consecutive, unselected patients undergoing laparoscopic subtotal colectomy (SCo) for IBD between 2008 and 2019 in a tertiary IBD Italian Centre. Starting from 2015, we regularly adopted the novel Sequential Approach for a Critical-View Colectomy (SACCo) technique. We included 59 (40.6%) patients treated with different laparoscopic approaches, and 86 patients (59.4%) operated on by the SACCo procedure. The mean operating time was significantly shorter for the SACCo group (144 vs. 224 min; p < 0.0001). The SACCo technique presented a trend to fewer major complications (6.8% vs. 8.3%), less readmissions (2.3% vs. 13.5%; p = 0.01), and shorter postoperative hospital stay (7.2 vs. 8.8 days; p = 0.003). Laparoscopic SACCo-technique is a safe and reproducible surgical approach for acute severe colitis and may improve the outcomes of this demanding procedure.

Abstract
BACKGROUND Outcome studies have failed to show significant improvement related to formal fellowship training in different surgical specialties. We aimed to look whether laparoscopic fellowship-trained (FT) surgeons had better outcomes. METHODS This is an IRB approved retrospective review from a single institution (inner city hospital) on adults undergoing appendectomy from 2008 to 2017. Demographics and 30-day complications were analyzed with univariate and multivariate logistic regression analyses. RESULTS Total of 558 appendectomies were reviewed. 151 (27.36%) appendectomies were performed by FT surgeons (MIS/CRS), 401 (72.64%) performed by GS. No difference in age, ASA, BMI, race, gender, insurance status, smoking, diabetes mellitus (DM), or hypertension was found. Also, similar rates of non-iatrogenic perforated appendicitis were seen (16.37% GS vs 20% FT, p = 0.318). For major complications, no difference was found between GS and FT (p = 0.63). However, appendectomies performed by GS showed higher rates of post-op ileus (3.99% vs 0.66%, p = 0.04), higher conversion to open (7.55% vs 2.67%, p = 0.039), higher rates of choosing an open approach (17.46% vs 0.66%, p = < 0.001), and longer length of stay (LOS) (median 1.9 vs 1.8 days p = 0.048). Of the 16 patients with ileus from the GS group three were open, two converted to open, and eleven laparoscopic with mean OR time of 70 min and LOS of 13.3 days. The only laparoscopic case from the FT group with ileus had a mean operative time of 56 min and LOS of 15 days. On multivariate regression analysis, only DM was found as risk factor for major complications (OR 3.01, 95% CI 1.307-6.92, p = 0.01), while laparoscopic approach was seen as protective factor against major complications (OR 0.53, 95% CI 0.29-0.97, p = 0.04). CONCLUSION Laparoscopic fellowship training had a positive outcome on post-op ileus and LOS after appendectomy. This seems to be related to the higher prevalence of choosing laparoscopic technique and lower rate of conversion to open.

Indocyanine green does not decrease the need for bail-out operation in an acute care surgery population. Surgery 2020; 169:227-231. [PMID: 32718803 DOI: 10.1016/j.surg.2020.05.045] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2020] [Revised: 04/02/2020] [Accepted: 05/27/2020] [Indexed: 12/30/2022]
Abstract
BACKGROUND The use of indocyanine green during laparoscopic cholecystectomy has been postulated to help to define anatomy. Studies have not specifically evaluated patients with acute cholecystitis. We sought to assess whether use of indocyanine green can decrease the rate of bail-out operation (subtotal cholecystectomy or conversion to an open operation) in an acute care surgery population where acute cholecystitis is more frequent. METHODS Using a retrospective cohort design, we examined all inpatient cholecystectomies performed by the acute care surgery service under urgent or semiurgent (biliary colic as the presentation in the emergency room) conditions at a single institution from 7/1/18 to 6/30/19 during which indocyanine green was available for use at the surgeon's discretion. RESULTS A total of 198 patients were included in the analysis. Demographic variables were similar in groups receiving indocyanine green versus not. Pathology confirmed acute cholecystitis was present in 96 of 198 (48.5%) patients; of those, 55 (57.2%) received indocyanine green. Indocyanine green did not change the rate of bail-out operation between patients who received indocyanine green and those who did not (6.7% vs 4.3%, P = .468). No significant differences in complications were observed. Bail-out operation was more likely in cases of acute cholecystitis (9.4%) versus nonacute cholecystitis (2.0%) (odds ratio = 5.172, P = .039). In patients with acute cholecystitis, indocyanine green did not change the rate of bail-out operation (indocyanine green: 12.7% vs no indocyanine green: 4.9%, P = .293). CONCLUSION This is the first series looking at the use of indocyanine green specifically in an acute care surgery population. Indocyanine green did not decrease operative time or need for a bail-out operation in acute cholecystitis. Further study is needed to determine whether indocyanine green use is justified in this population.

Abstract
BACKGROUND Laparoscopic cholecystectomy represents the gold standard technique for the treatment of lithiasic gallbladder disease. Although it has many advantages, laparoscopic cholecystectomy is not risk-free and in special situations there is a need for conversion into an open procedure, in order to minimize postoperative complications and to complete the procedure safely. The aim of this study was to identify factors that can predict the conversion to open cholecystectomy. METHODS We analyzed 1323 patients undergoing laparoscopic cholecystectomy over the last five years at St. Orsola University Hospital-Bologna and Umberto I University Hospital-Rome. Among these, 116 patients (8.7%) were converted into laparotomic cholecystectomy. Clinical, demographic, surgical and pathological data from these patients were included in a prospective database. A univariate analysis was performed followed by a multivariate logistic regression. RESULTS On univariate analysis, the factors significantly correlated with conversion to open were the ASA score higher than 3 and the comorbidity, specifically cardiovascular disease, diabetes and chronic renal failure (P<0.001). Patients with a higher mean age had a higher risk of conversion to open (61.9±17.1 vs. 54.1±15.2, P<0.001). Previous abdominal surgery and previous episodes of cholecystitis and/or pancreatitis were not statistically significant factors for conversion. There were four deaths in the group of converted patients and two in the laparoscopic group (P<0.001). Operative morbility was higher in the conversion group (22% versus 8%, P<0.001). Multivariate analysis showed that the factors significantly correlated to conversion were: age <65 years old (P=0.031 OR: 1.6), ASA score 3-4 (P=0.013, OR:1.8), history of ERCP (P=0.16 OR:1.7), emergency procedure (P=0.011, OR:1.7); CRP higher than 0,5 (P<0.001, OR:3.3), acute cholecystitis (P<0.001, OR:1.4). Further multivariate analysis of morbidity, postoperative mortality and home discharge showed that conversion had a significant influence on overall post-operative complications (P=0.011, OR:2.01), while mortality (P=0.143) and discharge at home were less statistically influenced. CONCLUSIONS Our results show that most of the independent risk factors for conversion cannot be modified by delaying surgery. Many factors reported in the literature did not significantly impact conversion rates in our results.

Abstract
Background: As minimally invasive pediatric surgery becomes standard approach to many surgical solutions, access has become an important point for improvement. Laparoscopic cholecystectomy (LC) is the gold standard for many conditions affecting the gallbladder; however, open cholecystectomy (OC) is offered as the initial approach in a surprisingly high percentage of cases. Materials and Methods: The Kids' Inpatient Database (1997-2012) was searched for International Classification of Disease, 9th revision, Clinical Modification procedure code (51.2x). LC and OC performed in patients <20 years old were identified. Propensity score-matched analyses using 39 variables were performed to isolate the effects of race, income group, location, gender, payer status, and hospital size on the percentage of LCs and OCs offered. Cases were weighted to provide national estimates. Results: A total of 78,578 cases were identified, comprising LC (88.1%) and OC (11.9%). Girls were 1.6 (CI: 1.4, 1.7) times more likely to undergo LC versus boys. Large facilities were 1.4 (1.3, 1.7) times more likely to perform LCs than small facilities. Children in lower income quartiles were 1.2 (1.1, 1.3) times more likely to undergo LC compared with those in higher income quartiles. Rates of LC were not affected by race, hospital location, or payer status. Conclusions: Risk-adjusted analysis of a large population-based data set demonstrated evidence that confirms, but also refutes, traditional disparities to minimally invasive surgery access. Despite laparoscopic gold standard, OC remains the initial approach in a surprisingly high percentage of pediatric cases independent of demographics or socioeconomic status. Additional research is required to identify factors affecting the distribution of LC and OC within the pediatric population.

Abstract
Introduction Gallstones are the major cause of global morbidity. Laparoscopic approach has well-established advantages as compared to the conventional open procedure. It promises better recovery, lower morbidity, and lower postoperative pain, shortens the duration of hospital stay, and has a lower mortality rate. The aim of this study is to assess the frequency of complications in laparoscopic cholecystectomies indicated for symptomatic gallstones and also evaluate the rate of conversion. Methods In this retrospective analysis, all records of laparoscopic cholecystectomy, in patients of age ≥18 years, for symptomatic gallstones, from January 2015 till December 2018 in one of the largest public tertiary care hospitals in Pakistan were included. Results The rate of complications associated with laparoscopic cholecystectomy was 6.8%. Older age, obesity, and multiple pre-operative risk factors were associated with complications. The most common intra-operative complication was hemorrhage (1.3%) and most common postoperative complication was surgical site infection (2.7%). Our conversion rate was 3.6%. Both intra-operative and postoperative complications were more common in procedures which were converted to open. Conclusion The rate of complication and conversion to open in laparoscopic cholecystectomy is not very high. Older age, obesity, and multi-morbidity was associated with complications. Complicated procedures were more commonly needed to be converted to open.

Abstract
PURPOSE Over the last 3 decades, laparoscopic procedures have emerged as the standard treatment for many elective and emergency surgical conditions. Despite the increased use of laparoscopic surgery, the role of laparoscopic repair for perforated peptic ulcer remains controversial among general surgeons. The aim of this study was to compare the outcomes of laparoscopic versus open repair for perforated peptic ulcer. METHODS A systemic literature review was conducted using Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines. A search was conducted using MEDLINE, EMBASE, PubMed and Cochrane Database of all randomised controlled trials (RCT) that compared laparoscopic (LR) with open repair (OR) for perforated peptic ulcer (PPU). Data was extracted using a standardised form and subsequently analysed. RESULTS The meta-analysis using data from 7 RCT showed that LR for PPU has decreased overall post-operative morbidity (LR = 8.9% vs. OR = 17.0%) (OR = 0.54, 95% CI 0.37 to 0.79, p < 0.01), wound infections, (LR = 2.2% vs. OR = 6.3%) (OR = 0.3, 95% CI 0.16 to 0.5, p < 0.01) and shorter duration of hospital stay (6.6 days vs. 8.2 days, p = 0.01). There were no significant differences in length of operation, leakage rate, incidence of intra-abdominal abscess, post-operative sepsis, respiratory complications, re-operation rate or mortality. There was no publication bias and the quality of the studies ranged from poor to good. CONCLUSION These results demonstrate that laparoscopic repair for perforated peptic ulcer has a reduced morbidity and total hospital stay compared with open approach. There are no significant differences in mortality, post-operative sepsis, abscess and re-operation rates. LR should be the preferred treatment option for patients with perforated peptic ulcer disease.

Abstract
BACKGROUND Laparoscopic ileo-pouch-anal anastomosis (IPAA) has been reported as having low morbidity and several advantages. AIMS To evaluate safety, efficacy and long-term results of laparoscopic IPAA, performed in elective or emergency settings, in consecutive unselected IBD patients. METHODS All the patients received totally laparoscopic 2-stage (proctocolectomy and IPAA - stoma closure) or 3-stage (colectomy - proctectomy and IPAA - stoma closure) procedure according to their presentation. RESULTS From July 2007 to July 2016, 160 patients entered the study. 50.6% underwent a 3-stage procedure and 49.4% a 2-stage procedure. Mortality and morbidity were 0.6% and 24.6%. Conversion rate was 3.75%. 8.7% septic complications were associated with steroids and Infliximab treatment (p = 0.0001). 3-stage patients were younger (p = 0.0001), with shorter disease duration (p = 0.0001), minor ASA scores of 2 and 3 (p = 0.0007), lower inflammatory index and better nutritional status (p = 0.003 and 0.0001), fewer Clavien-Dindo's grade II complications (p = .0001), reduced rates of readmission and reoperation at 90 days (p = 0.03), and shorter hospitalization (p = .0001), but with similar pouch and IPAA leakage, compared to 2-stage patients. 8 years pouch failure and definitive ileostomy were 5.1% and 3.7%. CONCLUSION A totally laparoscopic approach is safe and feasible, with very low mortality and morbidity rates and very low conversion rate, even in multi-stage procedures and high-risk patients.

Abstract
BACKGROUND Small bowel obstruction (SBO) due to adhesions is a common acute surgical presentation. Laparoscopic adhesiolysis is being performed more frequently. However, the clear benefits of laparoscopic adhesiolysis (LA) compared with traditional open adhesiolysis (OA) remain uncertain. The aim of this study was to compare the outcomes of LA versus OA for SBO due to adhesions. METHODS A systemic literature review was conducted using PRISMA guidelines. A search was conducted using MEDLINE, EMBASE, PubMed and Cochrane Databases of all randomised controlled trials (RCT) and case-controlled studies (CCS) that compared LA with OA for SBO. Data were extracted using a standardised form and subsequently analysed. RESULTS There were no RCT. Data from 18 CCS on 38,927 patients (LA = 5,729 and OA = 33,389) were analysed. A meta-analysis showed that LA for SBO has decreased overall mortality (LA = 1.6% vs. OA = 4.9%, p < 0.001) and morbidity (LA = 11.2% vs. OA = 30.9%, p < 0.001). Similarly, the incidences of specific complications are significantly lower in the LA group. There are significantly lower reoperation rate (LA = 4.5% vs. OA = 6.5%, p = 0.017), shorter average operating time (LA = 89 min vs. OA = 104 min, p < 0.001) and a shorter length of stay (LOS) (LA = 6.7 days vs. OA = 11.6 days, p < 0.001) in the LA group. In the CCS, there is likely to be a selection bias favouring less complex adhesions in the LA group that may contribute to the better outcomes in this group. CONCLUSIONS Although there is a probable selection bias, these results suggest that LA for SBO in selected patients has a reduced mortality, morbidity, reoperation rate, average operating time and LOS compared with OA. LA should be considered in appropriately selected patients with acute SBO due to adhesions.

Abstract
BACKGROUND Laparoscopic cholecystectomy (LC) is the standard surgical treatment for benign gallbladder disease. Nevertheless, conversion to open cholecystectomy (OC) is needed in some cases. The aim of this study is to calculate our institutional conversion rate and to identify the variables that are implicated in increasing the risk of conversion (LC-OC). MATERIALS AND METHODS We carried out a retrospective study of all cases of LC performed at the American University of Beirut Medical Center between 2000 and 2015. Each (LC-OC) case was randomly matched to a laparoscopically completed case by the same consultant within the same year of practice, as the LC-OC case, in a 1:5 ratio. Forty-eight parameters were compared between the two study groups. RESULTS Forty-eight out of 4668 LC were converted to OC over the 15-year study period; the conversion rate in our study was 1.03%. The variables that were found to be most predictive of conversion were male gender, advanced age, prior history of laparotomy, especially in the setting of prior gunshot wound, a history of restrictive or constrictive lung disease and anemia (Hb < 9 g/dl). The most common intraoperative reasons for conversion were perceived difficult anatomy or obscured view secondary to severe adhesions or significant inflammation. Patients who were in the LC-OC arm had a longer length of hospital stay. CONCLUSION Advance age, male gender, significant comorbidities and history of prior laparotomies have a high risk of conversion. Patients with these risk factors should be counseled for the possibility of conversion to open surgery preoperatively. Further research is needed to determine whether these high risks patients should be operated on by surgeons with more extensive experience in minimal invasive surgery.

Bile duct injuries (BDI) in the advanced laparoscopic cholecystectomy era. Surg Endosc 2018; 33:724-730.

Abstract
BACKGROUND Laparoscopic cholecystectomy is the most commonly performed laparoscopic procedure. It is superior in nearly every regard compared to open cholecystectomies. The one significant aspect where the laparoscopic approach is inferior regards the association with bile duct injuries (BDI). The BDI rate with laparoscopic cholecystectomy is approximately 0.5%; nearly triple the rate compared to the open approach. We propose that 0.5% BDI rate with the laparoscopic approach is no longer accurate. METHODS The National Surgical Quality Improvement Program (NSQIP) registry was retrospectively reviewed. All laparoscopic cholecystectomies performed between 2012 and 2016 were extracted. A total of 217,774 cases meeting inclusion criteria were analyzed. The primary data points were the overall BDI incidence rate and time of diagnosis. BDI were identified by ICD-9 and ICD-10 codes. Secondary data points were variables associated with BDI. RESULTS The BDI rate was 0.19%. 77% of cases were diagnosed after the index surgical admission. Intra-operative cholangiography (IOC) use was associated with a higher BDI rate and higher identification rate of a BDI intraoperatively (P value < 0.0001). Resident teaching cases were protective with a RR score of 0.56 (P value < 0.0001). The presence of cholecystitis increased the risk of a BDI with a RR score of 1.20 (P value < 0.0001). There was a low conversion rate of 0.04% however converted cases had a nearly hundredfold increase in BDI at 15% (P value < 0.0001). CONCLUSIONS The performance of laparoscopic cholecystectomies in North America is no longer associated with higher BDI rates compared to open. IOC use still is not protective against BDI, and cholecystitis continues to be a risk factor for BDI. When a cholecystectomy requires conversion from a laparoscopic to an open approach the BDI increases a hundredfold; which may raise the concern if this approach is still a safe bailout method for a difficult laparoscopic dissection.

Abstract
Background and Objectives: Open conversion (OC) occurs in 5 to 10% of laparoscopic cholecystectomies (LCs) and results in suboptimal outcomes. Herein, we report our experience with OC in cholecystectomy performed with the minimally invasive (MIS) approach. Methods: Data from 960 minimally invasive cholecystectomies performed in the University of Illinois at Chicago (UIC) Division of General, Minimally Invasive, and Robotic Surgery were retrospectively compiled. Patient demographics and outcomes were analyzed for the major indicators that may predispose to OC. Results: Male gender and intraoperative diagnosis of acute or gangrenous cholecystitis were identified as statistically significant individual predictors for OC. Conversion incidence was significantly lower in every paired demographic combination when compared with the laparoscopic data. Conclusions: Our retrospective study identified some specific factors associated with significantly higher risk of OC in both laparoscopic and robotic cholecystectomy. The impact of these risk factors seems to be lesser in the robotic than in the laparoscopic approach. Further investigation is necessary to validate these findings.

Abstract
BACKGROUND One-anastomosis gastric bypass (OAGB) is a promising laparoscopic procedure with various benefits including shorter operating times and less operative complications. That said, it is yet to gain widespread acceptance. Here, we describe our first-year experience with OAGB in our department, in particular the safety and efficacy of this procedure. METHODS This study is a retrospective analysis of all patients who underwent OAGB between March 2015 and March 2016 by our bariatric surgery unit. Patient demographics, comorbidities, operative and postoperative data were collected and analyzed as well as outcomes during the first year. RESULTS Four hundred and seven patients underwent OAGB (254 females, average age 41.8 ± 12.05, BMI = 41.7 ± 5.77 kg/m2). Ninety-eight patients (24%) had prior bariatric surgery. Ninety-four patients (23%) had diabetes, 93 patients (22.8%) had hypertension, 123 (28.8%) had hyperlipidemia, and 35 patients (8.6%) suffered from obstructive sleep apnea. Eight patients (1.96%) had early minor complications (Clavien-Dindo 1-3a), and 10 patients (2.45%) suffered early major complications (Clavien-Dindo ≥3b). The average length of hospital stay was 2.2 ± 0.84 days (range 2-10 days). Twenty patients (4.8%) were readmitted, and 10 patients underwent reoperation. Patients who had had previous bariatric surgery had higher rates of complications, a prolonged hospital admission, higher rates of readmission, and early reoperations. The average excess weight loss (%EWL) 1 year following surgery was 88.9 ± 27.3 and 72.8 ± 43.5% in patients that underwent primary and revision OAGB, respectively. CONCLUSIONS OAGB is both safe and effective as a primary as well as a revision bariatric surgery.

Abstract
Background and Objectives: Many risk factors have been identified in minimally invasive cholecystectomies that lead to higher complications and conversion rates. No study that we encountered looked at nonvisualization of the gallbladder (GB) during surgery as a risk factor. We hypothesized that nonvisualization was associated with an increased risk of complications and could be an early intraoperative identifier of a higher risk procedure. Recognizing this could allow surgeons to be aware of potential risks and to be more likely to convert to open for the safety of the patient. Methods: We looked at minimally invasive cholecystectomies performed at our institution from January 2015 through April 2016 and had the performing resident fill out a survey after the surgery. Outcomes were conversion rates, intraoperative complications, and blood loss and were analyzed via Pearson χ2 test or Mann-Whitney U test. Results: The primary outcome showed a conversion rate of 37% in nonvisualized GBs versus 0% in visualized (P = .001). Secondary outcomes showed significant differences in GB perforations (74% vs 13%, P = .001), omental vessel bleeding (16% vs. 0%, P = .005), and EBL (46 mL vs 29 mL, P = .001). Conclusions: Intraoperative nonvisualization of the GB after adequate positioning caused significantly increased risk of intraoperative complications and conversion. This knowledge could be useful during intraoperative assessment, to decide whether a case should be continued as a minimally invasive procedure or converted early to help reduce risk to the patient. Further randomized controlled studies should be performed to further demonstrate the value of this assessment.

Risk factors for difficulty of laparoscopic cholecystectomy in grade II acute cholecystitis according to the Tokyo guidelines 2013. BMC Surg 2017; 17:114.

Abstract
Background The Tokyo Guidelines 2013 classifies acute cholecystitis (AC) into three grades and recommends appropriate therapy for each grade. For grade II AC, either early laparoscopic cholecystectomy (LC) or percutaneous transhepatic gallbladder drainage (PTGBD) should be performed. This study aimed to identify the risk factors for difficulty of LC for treating grade II AC. Methods Totally, 122 patients who underwent LC for grade II AC were enrolled and divided into difficult LC (DLC) and nondifficult LC (NDLC) groups. The DLC group included patients who experienced one of the following conditions: conversion from LC to open cholecystectomy, operating time ≥ 180 min, or blood loss ≥300 ml. Preoperative characteristics and postoperative outcomes were analyzed. Results In univariate analysis, risk factors included male sex, interval between symptom onset and admission, interval between symptom onset and LC, and anticoagulant therapy. The incidence of postoperative complications was higher in the DLC group than in the NDLC group (23.5% vs. 4.6%, p = 0.0016). According to receiver operating characteristic curves, the optimal cutoff value was calculated, and multivariate analysis showed that male sex [odds ratio (OR), 5.76; 95% confidence interval (CI), 1.979–19.51; p = 0.0009) and interval between symptom onset and LC of over 96 h (OR, 6.32; 95% CI, 2.126–20.15; p = 0.0009) were independent risk factors for difficulty of LC. Conclusions In patients with grade II AC, LC was technically difficult when performed over 96 h after symptom onset. Moreover, male sex was a risk factor. Therefore, PTGBD should be considered in these patients.

Abstract
OBJECTIVE To identify preoperative factors associated with surgical time and conversion of the laparoscopic cholecystectomy (LC) to open surgery in subjects with acute cholecystitis (AC). METHOD We developed a cross-sectional study that included 99 subjects older than 17 years with definitive diagnosis of AC who had undergone to LC. Preoperative variables such as clinical data, laboratory markers and ultrasound findings as wall thickness, the size of the major calculus and the presence of: perivesicular fluid, multiple cholelithiasis, biliary mud or microlithiasis were registered. We consider indirect measures of technical difficulties of LC the total surgical time and the need for conversion to open surgery. We used the square chi and Mann-Whitney U test to stablish the correlation between preoperative variables and the technical difficulties of LC. We build ROC curves of the variables with significant statistical association (p ≤0.05 and 95% confidence interval [95%CI]) to determine the cut-off points of better sensitivity and specificity to predict conversion of LC to open surgery. RESULTS A gallbladder wall thickness ≥6mm detected by ultrasound has a sensitivity of 87.5% and a specificity of 62.6% with OR 11.71 (95%CI: 1.38-99; p = 0.008) for predict conversion to open surgery. There was no relationship between surgical time and the preoperative evaluated variables. CONCLUSION The gallbladder wall thickness detected by the ultrasound is associated with the need of conversion of LC to open surgery in subjects with AC, furthermore this finding could warn the surgeon on the complexity with a particular patient.

Abstract
BACKGROUND The aim of this study was to compare the outcomes of single-site robotic cholecystectomy with multi-port laparoscopic cholecystectomy within a high-volume tertiary health care center. METHODS A retrospective analysis of prospectively maintained data was conducted on patients undergoing single-site robotic cholecystectomy or multi-port laparoscopic cholecystectomy between October 2011 and July 2014. A single surgeon performed all the surgeries included in the study. RESULTS A total of 678 cholecystectomies were performed. Of these, 415 (61%) were single-site robotic cholecystectomies and 263 (39%) were multi-port laparoscopic cholecystectomies. Laparoscopic patients had a greater mean BMI (30.5 vs. 29.0 kg/m2; p = 0.008), were more likely to have undergone prior abdominal surgery (83.3 vs. 41.4%; p < 0.001) and had a higher incidence of preexisting comorbidities (76.1 vs. 67.2%; p = 0.014) as compared to the robotic group. There was no statistical difference in the total operative time, rate of conversion to open procedure and mean length of follow-up between the two groups. The mean length of hospital stay was shorter for patients within the robotic group (1.9 vs. 2.4 days; p = 0.012). Single-site robotic cholecystectomy was associated with a higher rate of wound infection (3.9 vs. 1.1%; p = 0.037) and incisional hernia (6.5 vs. 1.9%; p = 0.006). CONCLUSION Multi-port laparoscopic cholecystectomy should remain the gold standard therapy for gallbladder disease. Single-site robotic cholecystectomy is an effective alternative procedure for uncomplicated benign gallbladder disease in properly selected patients. This must be carefully balanced against a high rate of surgical site infection and incisional hernia, and patients should be informed of these risks.

Abstract
Laparoscopic cholecystectomy is usually a low-risk procedure associated with a short stay and a low rate of conversion to open surgery. Complications are sometimes associated with anomalous vascular or biliary anatomy. Outlined below are the variations in vascular and biliary anatomy which may result in complications either due to involvement in the inflammatory process or inadvertent division during dissection.

Abstract
Background and Objectives: Factors that contribute to difficult laparoscopic cholecystectomy (LC) in acute cholecystitis (AC) that would affect the performance of early surgery remain unclear. The purpose of this study was to identify such risk factors. Methods: One hundred fifty-four patients who underwent LC for AC were retrospectively analyzed. The patients were categorized into early surgery and delayed surgery. Factors predicting difficult LC were analyzed for each group. The operation time, bleeding, and cases of difficult laparoscopic surgery (CDLS)/conversion rate were analyzed as an index of difficulty. Analyses of patients in the early group were especially focused on 3 consecutive histopathological phases: edematous cholecystitis (E), necrotizing cholecystitis (N), suppurative/subacute cholecystitis (S). Results: In the early group, the CDLS/conversion rate was highest in necrotizing cholecystitis. Its rate was significantly higher than that of the other 2 histopathological types (N 27.9% vs E and S 7.4%; P = .037). In the delayed-surgery group, a higher white blood cell (WBC) count and older age showed significant correlations with the CDLS/conversion rate (P = .034 and P = .004). Conclusion: In early surgery, histopathologic necrotizing cholecystitis is a risk factor for difficult LC in AC. A higher WBC count and older age are risk factors for delayed surgery.

Abstract
BACKGROUND Minimally invasive distal pancreatectomy (MISDP) has been shown to be safe relative to open distal pancreatectomy (ODP). However, MISDP has been slow to adopt for pancreatic adenocarcinoma (PDAC). This study sought to compare outcomes following MISDP vs. ODP for PDAC. METHODS Data were prospectively collected from 2011 to 2014 for DP by the American College of Surgeons-National Surgical Quality Improvement Program. Patients without PDAC on surgical pathology were excluded. Impact of minimally invasive approach on morbidity and mortality was analyzed using two-way statistical analyses. RESULTS Of 6198 patients undergoing DP, 501 (7.5%) had a pathologic diagnosis of PDAC. MISDP was undertaken in 166 (33.1%) patients, ODP was performed in 335 (66.9%). MISDP and ODP were not different in preoperative comorbidities or pathologic stage. Overall morbidity (MISDP 31%, ODP 42%; p = 0.024), transfusion (MISDP 6%, ODP 23%; p = 0.0001), pneumonia (MISDP 1%, ODP 7%; p = 0.004), surgical site infections (MISDP 8%, OPD 17%; p = 0.013), sepsis (MISDP 2%, ODP 8%; p = 0.007), and length of stay (MISDP 5.0 days, ODP 7.0 days; p = 0.009) were lower in the MIS group. Mortality (MISDP 0%, ODP 1%; p = 0.307), pancreatic fistula (MISDP 12%, ODP 19%; p = 0.073), and delayed gastric emptying (MISDP 3%, ODP 7%; p = 0.140) were similar. CONCLUSIONS This analysis of a large multi-institution North American experience of DP for treatment of pancreatic adenocarcinoma suggests that short-term postoperative outcomes are improved with MISDP.

Abstract
BACKGROUND Although rare, injury to the common bile duct (CBD) during laparoscopic cholecystectomy (LC) can be reduced by better intraoperative visualization of the cystic duct (CD) and CBD. The aim of this study was to establish the efficacy of early visualization of the CD and the added value of CBD identification, using near-infrared (NIR) light and the fluorescent agent indocyanine green (ICG), in patients at increased risk of bile duct injury. MATERIALS AND METHODS Patients diagnosed with complicated cholecystitis and scheduled for LC were included. The CBD and CD were visualized with NIR light before and during dissection of the liver hilus and at critical view of safety (CVS). RESULTS Of the 20 patients originally included, 2 were later excluded due to conversion. In 6 of 18 patients, the CD was visualized early during dissection and prior to imaging with conventional white light. The CBD was additionally visualized with ICG-NIR in 7 of 18 patients. In 1 patient, conversion was prevented due to detection of the CD and CBD with ICG-NIR. CONCLUSIONS Early visualization of the CD or additional identification of the CBD using ICG-NIR in patients with complicated cholecystolithiasis can be helpful in preventing CBD injury. Future studies should attempt to establish the optimal dosage and time frame for ICG administration and bile duct visualization with respect to different gallbladder pathologies.

Abstract
BACKGROUND Although there is a large body of published data demonstrating improved outcomes for complex operations when performed by high-volume surgeons at high-volume hospitals, the literature is mixed regarding whether this same relationship applies in less complex and more common surgeries such as laparoscopic cholecystectomy. METHODS This study utilized the New York State Department of Health Statewide Planning and Research Cooperative System database to identify patients undergoing laparoscopic cholecystectomy for acute and chronic biliary pathology. Rates of perioperative outcomes were compared among 4 distinct categories of surgeons based on surgeon annual and cumulative volume: low cumulative/low annual, low cumulative/high annual, high cumulative/low annual, and high cumulative/high annual. RESULTS A total of 150,938 patients undergoing operation by 3,306 surgeons at 250 hospitals across New York state were included for analysis from 2000-2014. There was no difference in adjusted 30-day in-hospital mortality, major events, procedural complications, bile duct injury, or reintervention rates between the 4 groups of surgeons. However, patients undergoing operation by high cumulative/high annual volume surgeons were less likely to experience 30-day readmission, prolonged duration of stay, and high charges when compared with low cumulative/low annual volume surgeons. CONCLUSION In New York state, increased surgeon annual and cumulative volume predicts lower rates of 30-day readmission, prolonged duration of stay, and high charges in laparoscopic cholecystectomy, but has no effect on in-hospital mortality, major events, bile duct injury, procedural complications, or reintervention. There is no evidence to support regionalization of this procedure as operative outcomes are comparable even in less experienced hands.

Abstract
INTRODUCTION Although laparoscopic cholecystectomy is currently the standard treatment for benign gallbladder pathologies, some cases still require conversion to open cholecystectomy. Since open cholecystectomy has a significantly higher morbidity rate and a lengthier stay in the hospital compared with laparoscopic surgery, predicting this conversion would grant a great advantage in the management of cholecystitis. Therefore, in this study, we aimed to develop a predictive statistical model. MATERIALS AND METHODS Between August 2006 and January 2011, 1335 laparoscopic cholecystectomies were initiated at the General Surgery Department of Hacettepe University. One hundred four of these cases were started as laparoscopic surgeries, but converted to open cholecystectomies. In our study, we randomly chose 104 laparoscopically completed cases and compared them with the 104 converted cases. We used 31 parameters, including demographics, ultrasonographic findings, and laboratory values, to compare groups. These parameters were later included in a logistic regression analysis to create a statistical model that predicts conversion to open cholecystectomy. RESULTS Among the 1335 laparoscopically started cases, 104 (7.7%) were converted to open surgery. In our study, we found age, gender, ultrasonographic findings of acute cholecystitis, history of choledocolithiasis, history of abdominal surgery, and alkaline phosphatase (ALP) levels to be significant risk factors. By using a receiver operating characteristic curve, we found that the risk significantly increases after 55 years of age and an ALP over 80 IU/L. DISCUSSION Using four parameters-age, gender, history of abdominal surgery, and ALP-in our statistical model, we were able to predict the conversion from laparoscopic to open cholecystectomy with 70% sensitivity and 79% specificity.

Laparoscopic partial cholecystectomy: A safe and effective alternative surgical technique in "difficult cholecystectomies". ULUSAL CERRAHI DERGISI 2016; 32:185-90. [PMID: 27528821 DOI: 10.5152/ucd.2015.3086] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/21/2015] [Accepted: 02/16/2015] [Indexed: 12/22/2022]
Abstract
OBJECTIVE Laparoscopic cholecystectomy has become the "gold standard" for benign gallbladder diseases due to its advantages. In the presence of inflammation or fibrosis, the risk of bleeding and bile duct injury is increased during dissection. Laparoscopic partial cholecystectomy (LPC) is a feasible and safe method to prevent bile duct injuries and decrease the conversion (to open cholecystectomy) rates in difficult cholecystectomies where anatomical structures could not be demonstrated clearly. MATERIAL AND METHODS The feasibility, efficiency, and safety of LPC were investigated. The data of 80 patients with cholelithiasis who underwent LPC (n=40) and conversion cholecystectomy (CC) (n=40) were retrospectively examined. Demographic characteristics, ASA scores, operating time, drain usage, requirement for intensive care, postoperative length of hospital stay, surgical site infection, antibiotic requirement and complication rates were compared. RESULTS The median ASA value was 1 in the CC group and 2 in the LPC group. Mean operation time was 123 minutes in the CC group, and 87.50 minutes in the LPC group. Surgical drains were used in 16 CC patients and 4 LPC patients. There was no significant difference between groups in postoperative length of intensive care unit stay (p=0.241). When surgical site infections were compared, the difference was at the limit of statistical significance (p=0.055). Early complication rates were not different (p=0.608) but none of the patients in the LPC group suffered from late complications. CONCLUSION LPC is an efficient and safe way to decrease the conversion rate. LPC seems to be an alternative procedure to CC with advantages of shorter operating time, lower rates of surgical site infection, shorter postoperative hospitalization and fewer complications in high-risk patients.

Abstract
Objectives: There is limited data regarding the outcomes of patients who undergo conversion to open surgery during a laparoscopic operation in colorectal resection. We sought to identify the outcomes of such patients. Methods: The NIS (National Inpatient Sample) database was used to identify patients who had conversion from laparoscopic to open colorectal surgery during the 2009 to 2012 period. Multivariate regression analysis was performed to identify risk-adjusted outcomes of conversion to open surgery. Results: We sampled 776 007 patients who underwent colorectal resection. 337 732 (43.5%) of the patients had laparoscopic resection. Of these, 48 265 procedures (14.3%) were converted to open surgery. The mortality of converted patients was increased, when compared with successfully completed laparoscopic operations, but was still lower than that of open procedures (0.6% vs. 1.4% vs. 3.9%, respectively; adjusted odds ratio [AOR], 1.61 and 0.58, respectively; P < .01). The most common laparoscopic colorectal procedure was right colectomy (41.2%). The lowest rate of conversion is seen with right colectomy while proctectomy had the highest rate of conversion (31.2% vs. 12.9%, AOR, 2.81, P < .01). Postsurgical complications including intra-abdominal abscess (AOR, 2.64), prolonged ileus (AOR, 1.50), and wound infection (AOR, 2.38) were higher in procedures requiring conversion (P < .01). Conclusions: Conversion of laparoscopic to open colorectal resection occurs in 14.3% of cases. Compared with patients who had laparoscopic operations, patients who had conversion to open surgery had a higher mortality, higher overall morbidity, longer length of hospitalization, and increased hospital charges. The lowest conversion rate was in right colectomy and the highest was in proctectomy procedures. Wound infection in converted procedures is higher than in laparoscopic and open procedures.

Abstract
Background and Objectives: Laparoscopic splenectomy (LS) has been shown to offer superior outcomes when compared to open splenectomy (OS). Despite the potential advantages associated with the minimally invasive technique, laparoscopy appears to be underused. We sought to evaluate the nationwide trends in LS. Methods: The Nationwide Inpatient Sample (NIS) database was queried for both OS and LS procedures performed from 2005 through 2010. Partial splenectomies and those performed for traumatic injury, vascular anomaly, or as part of a pancreatectomy were excluded. The included cases were examined for age of the patient and comorbid conditions. We then evaluated the postoperative complications, overall morbidity, mortality, and length of hospital stay. Results: A total of 37,006 splenectomies were identified. Of those, OS accounted for 30,108 (81.4%) cases, LS for 4,938 (13.3%), and conversion to open surgery (CS) for 1,960 (5.3%). The overall rate of morbidity was significantly less in the LS group than in the OS group (7.4% vs 10.4%; P < .0001). The LS group had less mortality (1.3% vs 2.5%, P < .05) and a shorter length of stay (5.6 ± 8 days vs 7.5 ± 9 days). Conclusions: Despite the benefits conferred by LS, it appears to be underused in the United States. There has been an improvement in the rate of splenectomies completed laparoscopically when compared to NIS data from the past (8.8% vs 13%; P < .05). The conversion rate is appreciably higher for LS than for other laparoscopic procedures, suggesting that splenectomies require advanced laparoscopic skills and that consideration should be given to referring patients in need of the procedure to appropriately experienced surgeons.

Abstract
Introduction: We investigate the safety and efficacy of single-site robotic cholecystectomy compared to laparoscopic cholecystectomy at an inner-city academic medical center. Materials and Methods: Retrospective analysis comparing single-site robotic to laparoscopic cholecystectomies from August 1, 2013, to January 31, 2015, was conducted. Age, gender, race, body mass index (BMI), total operative time (docking and console time for robotic cases), length of stay, comorbidities, and conversion to open procedures were examined. The χ2 and Student's t test were used for categorical and continuous data, respectively. A P ≤ 0.05 was considered statistically significant. Results: From August 2013 to January 2015, 70 single-site robotic cholecystectomies and 70 laparoscopic cholecystectomies were performed. Patients were older (mean age, 40.3 years vs 47.6 years; P = .0084), had a higher mean BMI (29.5 vs 32.4 kg/m2; P = .011), and had a higher assigned ASA (American Society of Anesthesiologists) classification (P = .024) in the laparoscopic than in the single-site group. Hypertension was more common in the laparoscopic group (P = .0078). Average docking time was 11.5 (SD 5.7) minutes, and the average console time was 52.8 (SD 22.5) minutes in the single-site group. Total operating time for the laparoscopic and single-site groups was not significantly different (111.5 minutes vs 106.0 minutes; P = .38). There were more conversions to open procedures in the laparoscopic compared to the single-site group (11 vs 1; P = .007). There were no biliary tree injuries and no deaths in either group. Conclusion: Single-site robotic cholecystectomy is safe to perform in an inner-city academic hospital setting. Surgical resident involvement does not adversely affect outcomes.

Abstract
BACKGROUND The push for public reporting of outcomes necessitates relevant benchmarks for disease states across different settings. This study establishes benchmarks for choledocholithiasis management in a safety net hospital setting. METHODS We reviewed all patients admitted to our acute care surgery service with biochemical evidence of choledocholithiasis who underwent same-admission cholecystectomy (CCY) between July 2012 and December 2013. RESULTS During this 18-month period, 915 patients were admitted with biochemical evidence of choledocholithiasis. Descriptive statistics for the cohort are provided, which include a 51% rate of obesity and 95% rate of pathologic cholecystitis. Conversion rates of 4% and complication rates of 6% were found. The majority had a CCY without biliary imaging (n = 630, 68.9%). CONCLUSIONS Relevant benchmarks are characterized, and results of a practice pattern of omitting pre- or intraoperative biliary tree imaging are described. These findings serve as a first benchmark of choledocholithiasis management for urban safety net hospitals.

Abstract
BACKGROUND Bile duct injury (BDI) after laparoscopic cholecystectomy (LC) has significant cost impact and is a significant source of morbidity and mortality. We undertook a population-based assessment of the national experience with BDI between 2001 and 2011 and compared this to our report for the prior decade. METHODS Using the nationwide inpatient sample (NIS) for 2001-2011, we identified patients who underwent LC or partial cholecystectomy, with and without biliary reconstruction. Data were analyzed using methods that accounted for the hierarchical, stratified random sampling of the NIS. Both univariate modeling and multivariate modeling were performed. RESULTS LCs increased from 71.1 % in 2001 to 79.0 % in 2011 (p < 0.0001). Annual mortality decreased from 0.56 to 0.38 % (p = 0.002). In 2001, 0.11 % of LCs were associated with biliary reconstruction versus 0.09 % in 2011 (p = 0.15) with rates ranging from 0.08 to 0.12 %. The need for reconstruction was associated with an average in-hospital mortality rate of 4.4 %. Mortality rates from LC remained consistent across the study period (average mortality, 0.10 %, p = 0.57). Under multivariate analysis, admission to rural or urban non-teaching centers was associated with a decreased rate of injury; the majority of major BDIs were admitted from clinic or outpatient settings. These results are consistent with results from the prior decade. Neither emergent admission nor race was associated with increased odds of BDI, and this differs from our prior analysis. CONCLUSION LC continued to increase in utilization between 2001 and 2011. Although rates of BDI have decreased, the need for reconstruction continues to be associated with a significant mortality. In addition, mortality related to biliary reconstruction is also higher than previously published series and may reflect the complexity of managing biliary injury as well as the higher likelihood of these patients having comorbid conditions.

Abstract
BACKGROUND Although a laparoscopic cholecystectomy (LC) is the gold standard treatment for symptomatic cholelithiasis, its safety and efficacy in the morbidly/super obese patients is unknown. The aim of this study was to investigate the safety and efficacy of an elective LC in the morbid/super obese patients. METHODS A retrospective review of the hospital electronic database and medical records was conducted searching for all elective LC from 2010 to 2013. The data collected included patient demographics and body mass index (BMI), length of hospital stay (LOS), duration of surgery (DOS), intra- and post-operative complications, bile duct injuries, performance of an intra-operative cholangiogram, the incidence of open conversion and the seniority of the operator. RESULTS A total of 799 patients (76% female) with a mean age of 46 years and BMI of 31 were included in this study. There were significant differences in the median DOS between the three BMI groups; BMI < 26 [64 min; interquartile range (IQR) 54-83]; BMI 26-40 (72 min, IQR 58-91) and BMI > 40 (82 min, IQR 63-104), P < 0.001. There were no statistically significant differences in the LOS, peri-operative complication rates, open conversions or bile duct injuries among the BMI groups. CONCLUSIONS This study showed that LC can be performed safely in the morbid/super obese patients.

Abstract
Abstract
Background
The number of surgeons entering fellowship training before independent practice is increasing. This may have a negative impact on surgeons in training. The impact of fellowship training on patient outcomes is not yet known. This review aimed to investigate the impact of fellowship training in surgery on patient outcomes.
Methods
A systematic review of the literature was conducted to identify studies exploring the structural and surgeon-specific characteristics of fellowship training on patient outcomes. Data from these studies were extracted, synthesized and reported qualitatively, or quantitatively through meta-analysis.
Results
Twenty-three studies were included. The mortality rate for patients in centres with an affiliated fellowship programme was lower than that for centres without (odds ratio 0·86, 95 per cent c.i. 0·84 to 0·88), as was the rate of complications (odds ratio 0·90, 0·78 to 1·02). Surgeons without fellowship training converted more laparoscopic operations to open surgery than those with fellowship training (risk ratio (RR) 1·04, 95 per cent c.i. 1·03 to 1·05). Comparison of outcomes for senior surgeons versus current fellows showed no differences in rates of mortality (RR 1·00, 1·00 to 1·01), complications (RR 1·03, 0·98 to 1·08) or conversion to open surgery (RR 1·01, 1·00 to 1·01).
Conclusion
Fellowship training appears to have a positive impact on patient outcomes.

Abstract
BACKGROUND AND OBJECTIVES Robotic-assisted cholecystectomy (RAC) was introduced several years ago. With its more extensive use by surgeons, more information is needed regarding clinical and economic outcomes. METHODS The Nationwide Inpatient Sample from the Health Cost Utilization Project was analyzed using HCUPnet, National Inpatient Sample (NIS) datasets and SAS 9.2 for the years 2010-2011. Queries were made for RAC and laparoscopic cholecystectomy (LC) procedures with a primary diagnosis of gallbladder disease. Overall charges, costs, number of chronic conditions, comorbidities, and length of stay were calculated. RESULTS RAC was $7518, +54 % (p < 0.05), and $4044, +29 % (p < 0.05), more costly compared to LC in 2010 and 2011, respectively. Total costs for RAC decreased by 14.6 % (p = 0.27) between 2010 and 2011, even though RAC was still costlier than LC in 2011. There was no significant difference in the LOS between RAC and LC in either years. Patients undergoing RAC had an increased number of chronic conditions compared to patients undergoing LC in both 2010 and 2011. CONCLUSION LOS of RAC is similar to LC. Cost of RAC remains higher compared to LC although there was reduction in cost of RAC in 2011 versus 2010.
