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.

Comparison of Endoscopy First and Laparoscopic Cholecystectomy First Strategies for Patients With Gallstone Disease and Intermediate Risk of Choledocholithiasis: Protocol for a Clinical Randomized Controlled Trial. JMIR Res Protoc 2021; 10:e18837. [PMID: 33538700 PMCID: PMC7892280 DOI: 10.2196/18837] [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: 03/22/2020] [Revised: 08/04/2020] [Accepted: 11/10/2020] [Indexed: 12/22/2022] Open
Abstract
Background The optimal approach for patients with gallbladder stones and intermediate risk of choledocholithiasis remains undetermined. The use of endoscopic retrograde cholangiopancreatography for diagnosis should be minimized as it carries considerable risk of postprocedural complications, and nowadays, less invasive and safer techniques are available. Objective This study compares the two management strategies of endoscopic ultrasound before laparoscopic cholecystectomy and intraoperative cholangiography for patients with symptomatic cholecystolithiasis and intermediate risk of choledocholithiasis. Methods This is a randomized, active-controlled, single-center clinical trial enrolling adult patients undergoing laparoscopic cholecystectomy for symptomatic gallbladder stones with intermediate risk of choledocholithiasis. The risk of choledocholithiasis is calculated using an original prognostic score (the Vilnius University Hospital Index). This index in a retrospective evaluation showed better prognostic performance than the score proposed by the American Society for Gastrointestinal Endoscopy in 2010. A total of 106 participants will be included and randomized into two groups. Evaluation of bile ducts using endoscopic ultrasound and endoscopic retrograde cholangiography on demand will be performed before laparoscopic cholecystectomy for one arm (“endoscopy first”). Intraoperative cholangiography during laparoscopic cholecystectomy and postoperative endoscopic retrograde cholangiopancreatography on demand will be performed in another arm (“cholecystectomy first”). Postoperative follow-up is 6 months. The primary endpoint is the length of hospital stay. The secondary endpoints are accuracy of the different management strategies, adverse events of the interventions, duct clearance and technical success of the interventions (intraoperative cholangiography, endoscopic ultrasound, and endoscopic retrograde cholangiography), and cost of treatment. Results The trial protocol was approved by the Vilnius Regional Biomedical Research Ethics Committee in December 2017. Enrollment of patients was started in January 2018. As of June 2020, 66 patients have been enrolled. Conclusions This trial is planned to determine the superior strategy for patients with intermediate risk of common bile duct stones and to define a simple and safe algorithm for managing choledocholithiasis. Trial Registration ClinicalTrials.gov NCT03658863; https://clinicaltrials.gov/ct2/show/NCT03658863. International Registered Report Identifier (IRRID) DERR1-10.2196/18837

Optimising the outcomes of index admission laparoscopic cholecystectomy and bile duct exploration for biliary emergencies: a service model. Surg Endosc 2020; 35:4192-4199. [PMID: 32860135 PMCID: PMC8263394 DOI: 10.1007/s00464-020-07900-1] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2020] [Accepted: 08/17/2020] [Indexed: 01/12/2023]
Abstract
Aims The rate of acute laparoscopic cholecystectomy remains low due to operational constraints. The purpose of this study is to evaluate a service model of index admission cholecystectomy with referral protocols, refined logistics and targeted job planning. Methods A prospectively maintained dataset was evaluated to determine the processes of care and outcomes of patients undergoing emergency biliary surgery. The lead author has maintained a 28 years prospective database capturing standard demographic data, intraoperative details including the difficulty of cholecystectomy as well as postoperative outcome parameters and follow up data. Results Over five thousand (5555) consecutive laparoscopic cholecystectomies were performed. Only patients undergoing emergency procedures (2399,43.2% of entire group) were analysed for this study. The median age was 52 years with 70% being female. The majority were admitted with biliary pain (34%), obstructive jaundice (26%) and acute cholecystitis (16%). 63% were referred by other surgeons. 80% underwent surgery within 5 days (40% within 24 h). Cholecystectomies were performed on scheduled lists (44%) or dedicated emergency lists (29%). Two thirds had suspected bile duct stones and 38.1% underwent bile duct exploration. The median operating time was 75 min, median hospital stay 7 days, conversion rate 0.8%, morbidity 8.9% and mortality rate 0.2%. Conclusion Index admission cholecystectomy for biliary emergencies can have low rates of morbidity and mortality. Timely referral and flexible theatre lists facilitate the service, optimising clinical results, number of biliary episodes, hospital stay and presentation to resolution intervals. Cost benefits and reduced interval readmissions need to be weighed against the length of hospital stay per episode.

Laparoscopic Ultrasonography Versus Magnetic Resonance Cholangiopancreatography in Laparoscopic Surgery for Symptomatic Cholelithiasis and Suspected Common Bile Duct Stones. J Gastrointest Surg 2019; 23:1143-1147. [PMID: 30187333 DOI: 10.1007/s11605-018-3949-9] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/04/2018] [Accepted: 08/23/2018] [Indexed: 01/31/2023]
Abstract
BACKGROUND There continues to be controversy regarding the optimal screening modality in patients with symptomatic cholelithiasis and suspected common bile duct (CBD) stones. The aim of this study was to assess the diagnostic accuracy of laparoscopic ultrasonography (LUS) compared to magnetic resonance cholangiopancreatography (MRCP). METHODS Both LUS and MRCP were performed to evaluate the CBD stones and biliary anatomy in 200 patients undergoing laparoscopic surgery. Pre-, intra-, and postoperative data were collected prospectively and reviewed retrospectively. RESULTS Coexisting CBD stones were identified in 64 of 200 (32%) patients by surgical exploration or postoperative ERCP. For the detection of CBD stones, LUS yielded a positive predictive value of 100%, a negative predictive value of 99.3%, a sensitivity of 98.4%, and a specificity of 100%. Preoperative MRCP had a positive predictive value of 87.9%, a negative predictive value of 95.5%, a sensitivity of 90.6%, and a specificity of 94.1%. The non-random concordance between MRCP and LUS was considered to be excellent with a kappa coefficient of 0.92 (p < 0.01). CONCLUSIONS LUS can reduce the need for MRCP examination and can become the primary imaging method for the evaluation of CBD stones in laparoscopic surgery.

Utilisation of an operative difficulty grading scale for laparoscopic cholecystectomy. Surg Endosc 2019; 33:110-121. [PMID: 29956029 PMCID: PMC6336748 DOI: 10.1007/s00464-018-6281-2] [Citation(s) in RCA: 62] [Impact Index Per Article: 12.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/14/2017] [Accepted: 06/18/2018] [Indexed: 02/08/2023]
Abstract
BACKGROUND A reliable system for grading operative difficulty of laparoscopic cholecystectomy would standardise description of findings and reporting of outcomes. The aim of this study was to validate a difficulty grading system (Nassar scale), testing its applicability and consistency in two large prospective datasets. METHODS Patient and disease-related variables and 30-day outcomes were identified in two prospective cholecystectomy databases: the multi-centre prospective cohort of 8820 patients from the recent CholeS Study and the single-surgeon series containing 4089 patients. Operative data and patient outcomes were correlated with Nassar operative difficultly scale, using Kendall's tau for dichotomous variables, or Jonckheere-Terpstra tests for continuous variables. A ROC curve analysis was performed, to quantify the predictive accuracy of the scale for each outcome, with continuous outcomes dichotomised, prior to analysis. RESULTS A higher operative difficulty grade was consistently associated with worse outcomes for the patients in both the reference and CholeS cohorts. The median length of stay increased from 0 to 4 days, and the 30-day complication rate from 7.6 to 24.4% as the difficulty grade increased from 1 to 4/5 (both p < 0.001). In the CholeS cohort, a higher difficulty grade was found to be most strongly associated with conversion to open and 30-day mortality (AUROC = 0.903, 0.822, respectively). On multivariable analysis, the Nassar operative difficultly scale was found to be a significant independent predictor of operative duration, conversion to open surgery, 30-day complications and 30-day reintervention (all p < 0.001). CONCLUSION We have shown that an operative difficulty scale can standardise the description of operative findings by multiple grades of surgeons to facilitate audit, training assessment and research. It provides a tool for reporting operative findings, disease severity and technical difficulty and can be utilised in future research to reliably compare outcomes according to case mix and intra-operative difficulty.

Abstract
BACKGROUND We aimed to compare laparoscopic cholecystectomy (LC) and simultaneous laparoscopic transcystic common bile duct exploration (LTCBDE) using an ultrathin choledochoscope with LC followed by endoscopic retrograde cholangiopancreatography (ERC) and endoscopic sphincterotomy (ES) when indicated. METHODS We retrospectively reviewed the records of patients seen between 2004 and 2014 and treated with LC+LTCBDE or LC for gallstones and suspected choledocholithiasis. Postoperative complications and surgical outcomes were compared using t-test, Mann-Whitney U test, or chi-square test. RESULTS 115 patients underwent successful LC+LTCBDE and 112 LC; follow-up data was available for 103 and 106 patients, respectively. Seventeen patients (16.5%) in the LC+LTCBDE group and 10 (28.6%) in the LC+ERC+ES group developed complications (P = 0.114). The LC+LTCBDE group had a significantly higher rate of satisfactory biliary function outcomes than the LC+ERC+ES group (98.1% vs. 85.7%, respectively) (P = 0.017). CONCLUSIONS Single-step LC+LTCBDE using an ultrathin choledochoscope may provide better outcomes in patients with gallstones and suspected choledocholithiasis.

Abstract
BACKGROUND The debate regarding the merits of routine use of intraoperative cholangiography (IOC) during laparoscopic cholecystectomy (LC) continues to rage. We aim to analyze the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) database to identify patterns of utilization of cholangiography during LC as well as its impact on patient outcomes. STUDY DESIGN This is a retrospective cohort study of patients undergoing LC with or without IOC in the 2012 and 2013 ACS NSQIP database. Only patients without any preoperative biochemical evidence of the CBD stone were included in the analysis. Comparison between two groups and data analysis focused on the following primary outcomes: 30-day mortality, readmission, return to operating room and NSQIP collected morbidity. RESULTS Twenty-one percentage of patients undergoing LC without any biochemical abnormality are undergoing IOC. There were no statistically significant differences in thirty-day outcomes between two patient populations with regard to mortality, morbidity, cardiac, central nervous system, wound, deep vein thrombosis, sepsis, respiratory and urinary tract complications. Patients undergoing LC plus IOC were found to have statistically significant reduction in the rate of readmission related to the first operation (adjusted odds ratio 0.80, 95 % CI 0.70-0.92; P value = 0.002). Readmissions related to biliary complications including retained CBD following cholecystectomy were 1.61 times more likely in patients who underwent LC without cholangiography. CONCLUSION The use of IOC at the time of LC appears to be associated with a statistically significant decrease in re-admission rates, especially readmissions related to biliary complications.

Clinical significance of bile reflux into the pancreatic duct without pancreaticobiliary maljunction assessed by intraoperative cholangiography. Asian J Endosc Surg 2015; 8:296-302. [PMID: 25756368 DOI: 10.1111/ases.12181] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/04/2014] [Revised: 01/22/2015] [Accepted: 01/25/2015] [Indexed: 12/26/2022]
Abstract
INTRODUCTION Bile reflux into the pancreatic duct (BRPD) is sometimes demonstrated during intraoperative cholangiography (IOC) even in patients without pancreaticobiliary maljunction. However, the clinical significance of this finding in laparoscopic and open cholecystectomy is unclear. METHODS Among 484 patients who underwent cholecystectomy (372 laparoscopic, 112 open), patients whose pancreatic duct was depicted in IOC were selected. The value of pancreatic amylase (p-amylase) of the gallbladder bile, histological changes, and the immunohistochemical expression of proliferating cell nuclear antigen (PCNA) in the gallbladder mucosa were analyzed in patients with BRPD. The data were then compared to those in patients without BRPD whose gallbladder bile p-amylase was measured (control group, n = 20). RESULTS The success rate of IOC was 93.6%. The rate of BRPD in laparoscopic and open cholecystectomy was 5.2% and 5.7%, respectively. The value of gallbladder bile p-amylase in patients with BRPD was significantly higher than in the control group (790.5 vs 14.0 IU/L, P = 0.034). The value of the PCNA labeling index in patients with BRPD was significantly higher than that of the control group (15.4% vs 4.1%, P = 0.0026). Among the 24 patients with BRPD, pathological changes in the gallbladder mucosa were detected in five (two hyperplasia, three metaplasia), but there was no correlation between the presence of pathological change and PCNA labeling index or gallbladder bile p-amylase. CONCLUSIONS IOC could detect BRPD both in laparoscopic and open cholecystectomy at a similar rate. Patients with BRPD had high levels of gallbladder bile p-amylase and PCNA labeling index, findings similar to those in patients with pancreaticobiliary maljunction.

Abstract
BACKGROUND The choice of surgical technique to extract stones from the common bile duct (CBD) depends on local experience, anatomical characteristics and also on the size, location and number of stones. Most authors consider choledochotomy an alternative to failed transcystic exploration, although some use it exclusively. Although the CBD is traditionally closed with T-tube drainage after choledochotomy, its use is associated with 11.3-27.5 % morbidity. This study examined the efficacy of laparoscopic CBD exploration (LCBDE) with primary closure for the treatment of CBD stones using intraoperative cholangiography (IOC). METHODS Retrospective study of 160 patients who underwent LCBDE with primary closure after choledochotomy between January 2001 and December 2012. RESULTS The diagnosis of choledocholithiasis was definitively made in all cases by IOC. The overall complication rate was 15 % and the biliary complication rate was 7.5 %. Bile leakage was reported in 11 patients (6.8 %). In over half the cases (63.6 %), no further action was required and the leak closed spontaneously. Six patients were reoperated (3.75 %), two for bile peritonitis and four for haemoperitoneum. The success rate for stone clearance was 96.2 %. The mortality rate and CBD stricture rate were 0 %. CONCLUSION Primary closure after choledochotomy to clear stones from the CBD is a safe technique that confers excellent results and allows one-stage treatment.

Abstract
BACKGROUND When common bile duct (CBD) stones are detected during laparoscopic cholecystectomy, the insertion of baskets via the cystic duct (CD) can be difficult and may occasionally cause complications. We introduced a new technique 'basket in catheter' (BIC) for transcystic CBD exploration. METHODS Although cannulating the CD using a cholangiography catheter is successful in most cases, it may occasionally be difficult. Cystic duct anatomy may prevent the usually stiffer sharper tip of the basket, from entering the CBD, resulting in failure, perforation or a false passage. In the majority of our cases, the cholangiography catheter (CC) is not withdrawn from the duct should the intraoperative cholangiography show CBD stones. The tip of a basket is inserted into the CC and advanced to a predetermined distance, allowing the tip of the basket to exit the end of the CC into the CBD. The basket is then opened, advanced to feel the lower end and manipulated to trap the stone. The common hepatic duct is compressed gently to prevent stones from slipping upwards. The catheter and basket are pulled back together to extract the stone. RESULTS We have used this technique in 274 cases since 2010. The rate of transcystic versus choledochotomy stone extraction has increased, saving unnecessary choledochotomies. The percentage of transcystic exploration increased from 55 % for the period 2005-2009 to 70 % for the period 2010-2014. There were no conversions to open surgery and no retained stones. The morbidity rate was 4.0 % with no mortality. CONCLUSIONS We demonstrate a technique to facilitate the insertion of extraction baskets into the common bile duct using the cholangiography catheter as a guide. The 'basket-in-catheter' (BIC) technique for transcystic CBD exploration is easier and safer than inserting the basket alone.

Abstract
BACKGROUND Laparoscopic CBD exploration (LCBDE) is an accepted treatment modality for single stage management of CBD stones in fit patients. A transcholedochal approach is preferred in patients with a dilated CBD and large impacted stones in whom ductal clearance remains problematic. There are very few studies comparing intraoperative cholangiography (IOC) with choledochoscopy to determine ductal clearance in patients undergoing transcholedochal LCBDE. This series represents the first of those comparing the two from Asia. METHODS Between April 2009 and October 2012, 150 consecutive patients with CBD stones were enrolled in a prospective randomized study to undergo transcholedochal LCBDE on an intent-to-treat basis. Patients with CBD diameter of less than 9 mm on preoperative imaging were excluded from the study. Out of the 132 eligible patients, 65 patients underwent IOC (Group A), and 67 patients underwent intraoperative choledochoscopy (Group B) to determine CBD clearance. RESULTS There were no differences between the two groups in the demographic profile and the preoperative biochemical findings. There was no conversion to open procedures, and complete stone clearance was achieved in all the 132 cases. The mean CBD diameter and the mean number of CBD stones removed were comparable between the two groups. Mean operating time was 170 min in Group A and 140 min in Group B (p < 0.001). There was no difference in complications between the two groups. Nine patients in Group A (13.8%) showed non-passage of contrast into the duodenum on IOC which resolved after administration of i.v. glucagon, suggesting a transient spasm of sphincter of Oddi. Two patients (3%) showed a false-positive result on IOC which had to be resolved with choledochoscopy. CONCLUSIONS The present study showed that intraoperative choledochoscopy is better than IOC for determining ductal clearance after transcholedochal LCBDE and is less cumbersome and less time-consuming.

Abstract
BACKGROUND Routine performance of intraoperative cholangiography (IOC) during cholecystectomy is controversial. The aim of this study was to evaluate the role of IOC during cholecystectomy in addition to preoperative magnetic resonance cholangiopancreatography (MRCP) in our institution over a 12-year period. METHODS A total of 425 consecutive patients who underwent IOC during cholecystectomy were included in this study. MRCP was performed preoperatively for bile duct evaluation in all patients. When common bile duct (CBD) stones were detected, they were removed endoscopically before the operation. We estimated the results of IOC in terms of the success rate, the detection rate of anatomic abnormality of the biliary system, and the incidence of residual CBD stones. RESULTS MRCP preoperatively identified 6 (1.4 %) patients with abnormal biliary systems and 56 with CBD stones, which were endoscopically removed. The success rate of IOC was 93.8 % (399/425). Abnormalities of the biliary system were detected in 12 patients (12/399, 3.0 %) and CBD stones in 8 (8/399, 2.0 %). Of the eight patients with stones, seven had been examined by endoscopy preoperatively and found to have CBD stones. The detection rate of bile duct stones in patients with preoperative endoscopic removal of CBD stones (7/56, 12.5 %) was significantly higher than those with CBD stones first detected during IOC (1/365, 0.3 %) (p < 0.01). Moreover, no residual CBD stones were detected in patients who were operated on within fewer than 12 days from endoscopic treatment to the operation. CONCLUSIONS IOC is indicated even after preoperative sphincterotomy for CBD stones. In our study, it resulted in a 12.5 % incidence of persistent stones after sphincterotomy. IOC plays an additional role in detecting CBD stones and in revealing abnormalities of the biliary tree in patients whose biliary tree was preoperatively evaluated by MRCP.

Intrahepatic choledochoscopy during trans-cystic common bile duct exploration; technique, feasibility and value. Surg Endosc 2012; 26:3190-4.

Abstract
BACKGROUND Transcystic laparoscopic common bile duct exploration (TC-LCBDE) is advantageous for exploring the bile duct. Choledochoscopy, however, may be quite challenging to perform transcystically because the cystic duct is usually narrow, duct anatomy may be unfavorable, and not all stones are amenable to transcystic extraction. Convention suggests that it is technically very difficult to visualize the intrahepatic bile ducts with transcystic choledochoscopy, due to the angle of insertion of the cystic into the common bile duct (CBD). However, we have performed intrahepatic choledochoscopy successfully, moving the choledochoscope from the CBD into the common hepatic duct by using what we have termed a "wiper blade maneuver". The purpose of this study was to confirm how often this was possible. METHODS A search of a prospectively collected database of patients undergoing routine intraoperative cholangiography (IOC) and laparoscopic CBD exploration under the care of a single consultant surgeon was performed. RESULTS A total of 592 LCBDEs were performed between September 1992 and January 2011; 325 were transcystic explorations. Of these, 72.5 % were female and 56 % were admitted acutely. Exploration and duct clearance was performed by blind Dormia basket trawling in 63 %. The choledochoscope was utilized in 120 cases (37 %). The 3-mm choledochoscope was used in 66 (55 %) and the 5-mm scope in 54 (45 %). Intrahepatic choledochoscopy was performed in 49 patients (40.8 %). Length of surgery was 40-350 min (median 90 min; standard deviation 49 min). CONCLUSIONS It is technically challenging to perform intrahepatic choledochoscopy with a 3-mm choledochoscope due to its narrow gauge. The more rigid 5-mm scope is thus preferred, but is limited in TCE because its effective use depends on the presence of a dilated cystic duct. Despite the technical limitations of both caliber scopes, we have demonstrated that intrahepatic choledochoscopy during TCE is possible, with each, in 40 % of cases.

Laparoscopic transcystic bile duct exploration: the treatment of first choice for common bile duct stones. Surg Endosc 2010; 24:1552-6. [PMID: 20044767 DOI: 10.1007/s00464-009-0809-4] [Citation(s) in RCA: 51] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2009] [Accepted: 11/13/2009] [Indexed: 01/22/2023]
Abstract
BACKGROUND This study was designed to explore the role of transcystic bile duct exploration (TCE) as a first line of treatment for patients with suspected or incidental common bile duct (CBD) stones. METHODS A prospective, case-control study of clinically comparable groups of patients who underwent laparoscopic cholecystectomy (LC) alone (n = 1,854) and combined LC/TCE for CBD stones (n = 253) under the care of one surgeon was performed. Other than ultrasonography, no routine preoperative imaging was used; however, we performed routine intraoperative cholangiography on all patients. RESULTS There was no difference in age (49 +/- 15 vs. 57 +/- 19, p = 0.7), sex (79% vs. 82% females, p = 0.6), and ASA grade (1.9 +/- 1 vs. 1.8 +/- 1, p = 0.7). A larger proportion of the TCE group presented as an emergency (TCE 45% vs. LC alone 27%, p = 0.03) and more often presented with acute biliary pain compared with LC alone (27% vs. 13%, p = 0.02). Although a majority of the patients in the TCE group had clinical or biochemical risk factors for CBD stones (86%), only 27% had suspected stones on preoperative ultrasound. The incidence of jaundice (6% vs. 20%, p = 0.01) was lower in the LC alone group compared with TCE patients. Previous abdominal surgery was noted in 34% patients who underwent LC alone and 30% in LC/TCE (p = 0.06). Significantly there was no difference in open conversion between the two groups (LC alone 0.5% vs. LC/TCE 0.6%, p = 0.07). Comparison of selected outcome parameters for LC versus TCE showed a postoperative hospital stay of 2 (1-14) vs. 2 (1-17) days (p = 0.07), presentation to resolution 1 (1-11) vs. 1 (1-11) weeks (p = 0.07), and morbidity 1.07% vs. 1.2% (p = 0.07). CONCLUSIONS The study advocates single-session laparoscopic cholecystectomy with transcystic CBD exploration as a feasible first choice treatment and the logical next step in the management of patients with CBD stones.

Various techniques for the surgical treatment of common bile duct stones: a meta review. Gastroenterol Res Pract 2009; 2009:840208. [PMID: 19672460 PMCID: PMC2722154 DOI: 10.1155/2009/840208] [Citation(s) in RCA: 51] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/23/2009] [Accepted: 05/25/2009] [Indexed: 02/08/2023] Open
Abstract
Common bile duct stones (CBDSs) may occur in up to 3%–14.7% of all patients for whom cholecystectomy is preformed. Patients presenting with CBDS have symptoms including: biliary colic, jaundice, cholangitis, pancreatitis or may be asymptomatic. It is important to distinguish between primary and secondary stones, because the treatment approach varies. Stones found before, during, and after cholecystectomy had also differing treatments. Different methods have been used for the treatment of CBDS but the suitable therapy depends on conditions such as patient' satisfaction, number and size of stones, and the surgeons experience in laparoscopy. Endoscopic retrograde cholangiopancreatography with or without endoscopic biliary sphincterotomy, laparoscopic CBD exploration (transcystic or transcholedochal), or laparotomy with CBD exploration (by T-tube, C-tube insertion, or primary closure) are the most commonly used methods managing CBDS. We will review the pathophysiology of CBDS, diagnosis, and different techniques of treatment with especial focus on the various surgical modalities.

Is laparoscopic fiberoptic choledochoscopy for common bile duct stones a fine option or a mandatory step? Surg Endosc 2009; 24:547-53. [PMID: 19585071 DOI: 10.1007/s00464-009-0599-8] [Citation(s) in RCA: 11] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2009] [Revised: 05/27/2009] [Accepted: 06/12/2009] [Indexed: 01/18/2023]
Abstract
BACKGROUND Because choledochoscopy often is a challenging maneuver, it would be advantageous to define the real utility of its use. This study aimed to compare blind exploration of the common bile duct (CBD) with choledochoscopy-assisted CBD stone removal in terms of patient outcome and complication rate. METHODS Two groups of patients were prospectively evaluated in a 4-year period. The study participants were 36 men and 27 women randomized to group A (n = 32) for a blind basket procedure or group B (n = 31) for a choledochoscopy-assisted procedure as the first step of laparoscopic CBD stone removal. Patients with preoperatively suspected CBD stones (n = 51) and those with unsuspected stones (n = 12) were included. The two groups did not differ significantly in terms of anagraphics, American Society of Anesthesiology (ASA) score, or previous surgery. All the procedures were performed by surgeons skilled in this surgical field. Choledochoscopy, when used, was always performed with the instrument connected to a camera monitor that had a wide vision, whether in a single-monitor, in a picture-in-picture manner, or with the use of an additional monitor. RESULTS From March 2004 to April 2008, 63 patients undergoing CBD exploration for stone removal were enrolled in the study. Five of these patients had undergone previous endoscopic retrograde cholangiopancreatography (ERCP)/endoscopic sphincterotomy (ES). The mean operative time was 107 min for group A and 122 min for group B. The mean hospital stay was 3 days for group A and 3.6 days for group B. Clearance of CBD stones was achieved laparoscopically in 62 cases. One patient required open combined transduodenal papilloplasty and transcholedochotomy. In seven cases, blind basket exploration was unable to remove the stones according to the cholangiogram, so choledochoscopy was required. Six patients underwent a transversal coledocothomy for stone removal. A Kehr T-tube was placed in four of these patients. In four group A cases, the papilla was inadvertently passed during the procedure. In six group A cases, including the four aforementioned cases, a high level of amylases was found on postoperative day 1. At this writing, no late complications or stone recurrences have been observed in either group. CONCLUSIONS The laparoscopic basket blind technique and choledochoscopy are safe and effective for CBD stone removal. However, the latter seems to be better in terms of a higher stone removal rate and fewer minor complications despite its longer operation time. In the authors' opinion, it may be preferable to reserve ERCP for very high-risk patients, taking into account that in addition to the related complications, it results in an approximate 10% rate of recurrent or persistent stones.

For patients with predicted low risk for choledocholithiasis undergoing laparoscopic cholecystectomy, selective intraoperative cholangiography and postoperative endoscopic retrograde cholangiopancreatography is an effective strategy to limit unnecessary procedures. Surg Endosc 2008; 23:1933-7. [PMID: 19116743 DOI: 10.1007/s00464-008-0250-0] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2008] [Accepted: 10/17/2008] [Indexed: 12/20/2022]
Abstract
BACKGROUND There is debate about whether intraoperative cholangiography (IOC) should be performed routinely or selectively during laparoscopic cholecystectomy (LC) in patients with suspected choledocholithiasis. The timing of endoscopic retrograde cholangiopancreatography (ERCP) in these patients also is an issue. We reviewed the experience in our center, where a management algorithm limiting ERCP in relation to LC was adopted. METHODS We retrospectively reviewed every LC performed by one surgeon during 6 years and the related ERCPs. RESULTS A total of 264 LCs were performed. In 30 patients, stones were cleared or excluded by preoperative ERCP. In the remaining 234 LCs, 31 of 34 IOCs were successfully performed. Two of 31 IOCs were positive for bile duct stones; stone removal was successful in each patient at subsequent ERCP. Only 10 of 201 patients who did not have IOC required postsurgical ERCP within 10 weeks of LC, 3 of whom had common bile duct stones at ERCP. CONCLUSIONS For patients who underwent LC, we performed selective IOC with postoperative ERCP for positive studies. Review of our experience using this algorithm showed it to be a powerful tool in limiting unnecessary ERCPs. Our data suggest that routine preoperative ERCP cannot be justified. Selective IOC during LC misses relatively few cases of biliary stones; these can be managed quickly by experienced endoscopists.

Management of preoperatively suspected choledocholithiasis: a decision analysis. J Gastrointest Surg 2008; 12:1973-80. [PMID: 18683008 DOI: 10.1007/s11605-008-0624-6] [Citation(s) in RCA: 56] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/19/2008] [Accepted: 07/15/2008] [Indexed: 01/31/2023]
Abstract
BACKGROUND The management of symptomatic or incidentally discovered common bile duct (CBD) stones is still controversial. Of patients undergoing elective cholecystectomy for symptomatic cholelithiasis, 5-15% will also harbor CBD stones, and those with symptoms suggestive of choledocholithiasis will have an even higher incidence. Options for treatment include preoperative endoscopic retrograde cholangiopancreatography (ERCP) with sphincterotomy (ERCP/ES) followed by laparoscopic cholecystectomy, laparoscopic cholecystectomy with intraoperative cholangiogram (LC/IOC), followed by either laparoscopic common bile duct exploration (LCBDE) or placement of a common bile duct double-lumen catheter with postoperative management. The purpose of this analysis was to determine the optimal management of such patients. METHODS A decision analysis was performed to analyze the management of patients with suspected common bile duct stones. The basic choice was between preoperative ERCP/ES followed by LC, LC/IOC followed by LCBDE, or common duct double-lumen catheter (Fitzgibbons tube) placement with either expectant management or postoperative ERCP/ES. Data on morbidity and mortality was obtained from the literature. Sensitivity analysis was done varying the incidence of positive CBD stones on IOC with associated morbidity and mortality. RESULTS One-stage management of symptomatic CBD stones with LC/LCBDE is associated with less morbidity and mortality (7% and 0.19%) than two-stage management utilizing preoperative ERCP/ES (13.5% and 0.5%). Sensitivity analysis shows that there is an increase in morbidity and mortality for LC/LCBDE as the incidence of positive IOC increases but are still less than two-stage management even with a 100% positive IOC (9.4%, 0.5%). If a double-lumen catheter is to be used for positive IOC, the morbidity would be higher than two-stage management only if the positive IOC incidence is more than 65% but still with no mortality. CONCLUSION LCBDE has lower morbidity and mortality rates compared to preoperative ERCP/ES in the management of patients with suspected CBD stones even if the chance of CBD stones reaches 100%. Using a common duct double-lumen catheter may be considered if LCBDE is not feasible and the chance of CBD stone is less than 65%.

Optimising laparoscopic cholangiography time using a simple cannulation technique. Surg Endosc 2008; 23:513-7. [PMID: 18392894 DOI: 10.1007/s00464-008-9853-8] [Citation(s) in RCA: 9] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/18/2007] [Revised: 12/29/2007] [Accepted: 01/18/2008] [Indexed: 10/22/2022]
Abstract
BACKGROUND Opponents of the routine use of intraoperative cholangiography (IOC) express concern over its technical difficulty and the length of time it takes. AIM To evaluate the impact of our cystic duct cannulation (CDC) technique, as implemented by one consultant and his trainees, on the IOC time. METHODS IOC is done routinely in all the laparoscopic cholecystectomies (LCs) undertaken in our unit. We carried out a prospective audit over a period of 18 months, recording the IOC time in consecutive patients undergoing laparoscopic cholangiography (LC) with and without laparoscopic common bile duct exploration (LCBDE). The total IOC time was considered to consist of two components: cystic duct cannulation (CDC) time and fluoroscopy time. The IOC time was further analysed according to the difficulty of cannulation and the operator experience. Special consideration was given to the LCBDE cases. We also describe the detailed steps of our CDC technique. RESULTS Over a period of 18 months 243 patients underwent LC. IOC was completed in 240 patients (98.8% success rate). Of those, 194 were females (81%). The mean age was 50 years (range 18-85 years). The mean total IOC time was 6 min, with a CDC time of 2 min, and fluoroscopy time of 4 min. On further analysis, CDC was considered easy in 86% of cases with a mean CDC time of 1.5 min and total IOC time of 4.3 min. When cannulation was difficult (14% of cases) a cholangiography clamp had to be used to prevent leakage of contrast. In difficult cases, the CDC and IOC mean times were 5 and 8.5 min, respectively. As would be expected, trainees spent more time performing cannulation and completing the IOC than the specialist surgeon (3.8 versus 1.8 min, and 7.2 versus 5.6 min, respectively). These differences were statistically but not clinically significant. Similarly, the IOC time was also significantly increased in LCBDE (13 min). This was mainly due to an increase in fluoroscopy time (10 min) rather than CDC time (3 min). CONCLUSION The IOC time could be optimised by using a simple and learnable cannulation technique to less than 5 min in most LCs. Surgeons should not, therefore, refrain from using this important investigation on selective or routine basis, subject to their policy for dealing with patients with suspected bile duct stones.

Abstract
AIM: To evaluate the feasibility and safety of performing laparoscopic cholecystectomy (LC) in non-teaching rural hospitals of a developing country without intra-operative cholangiography (IOC). To evaluate the possibility of reduction of costs and hospital stay for patients undergoing LC.
METHODS: A prospective analysis of patients with symptomatic benign diseases of gall bladder undergoing LC in three non-teaching rural hospitals of Kashmir Valley from Jan 2001 to Jan 2007. The cohort represented a sample of patients requiring LC, aged 13 to 78 (mean 47.2) years. Main outcome parameters included mortality, complications, re-operation, conversion to open procedure without resorting to IOC, reduction in costs borne by the hospital, and the duration of hospital stay.
RESULTS: Twelve hundred and sixty-seven patients (976 females/291 males) underwent laparoscopic cholecystectomy. Twenty-three cases were converted to open procedures; 12 patients developed port site infection, nobody died because of the procedure. One patient had common bile duct (CBD) injury, 4 patients had biliary leak, and 4 patients had subcutaneous emphysema. One cholecystohepatic duct was detected and managed intraoperatively, 1 patient had retained CBD stones, while 1 patient had retained cystic duct stones. Incidental gallbladder malignancy was detected in 2 cases. No long-term complications were detected up to now.
CONCLUSION: LC can be performed safely even in non-teaching rural hospitals of a developing country provided proper equipment is available and the surgeons and other team members are well trained in the procedure. It is stressed that IOC is not essential to prevent biliary tract injuries and missed CBD stones. The costs to the patient and the hospital can be minimized by using reusable instruments, intracorporeal sutures, and condoms instead of titanium clips and endobags.
