Useful Predictors of Bile Duct Stones in Patients Undergoing Laparoscopic Cholecystectomy
Annals of Surgery, 1994
The authors determined the most useful predictors of common bile duct (CBD) stones as diagnosed by endoscopic retrograde cholangiopancreatography (ERCP) in patients who underwent laparoscopic cholecystectomy (LC). Methods Prospective and retrospective collection of historical, biochemical and ultrasonographic data was used. Receiver operating characteristics curve analysis was used to determine optimal biochemical cutoff values. Multivariate analysis using logistic regression with generation of the best model identifying independent predictors of CBD stones also was employed. Prospective validation of the model was performed on an independent group of patients. Results Endoscopic retrograde cholangiopancreatographies were performed before LC in 106 patients, and after LC in 33. Only four of ten clinical variables evaluated independently predicted the presence of CBD stones. The optimal model predicted a 94% probability of CBD stones in a patient older than 55 years of age who presented with an elevated bilirubin (over 30 ,umol/L) and positive ultrasound findings (a dilated CBD, and a CBD stone seen on ultrasound). This model was validated prospectively in a subsequent series of 49 patients in which the probability of CBD stone was only 8% when all four predictors were absent. Conclusions The identified independent clinical predictors of a CBD stone helps select a population of symptomatic gallstone bearers who benefit most from cholangiographic assessment. Laparoscopic cholecystectomy (LC) has become the now treated this way.2 However, 3% to 33% ofall patients new therapeutic gold standard' in uncomplicated symp-with symptomatic gallstones may bear associated comtomatic cholelithiasis, and at least 80% of all patients are mon bile duct (CBD) stones.3-7 The optimal approach to

Background/Aims: Several studies recommend prompt laparoscopic cholecystectomy (LC) following endoscopic retrograde cholangiopancreatography (ERCP) for choledocholithiasis. However, histopathological alterations in the gallbladder during this time interval and the role played by ERCP in causing these changes have not been sufficiently elucidated. To compare early period LCs with delayed LCs following common bile duct stone extraction via ERCP with regard to operation time, hospitalization period, conversion to open cholecystectomy rate, morbidity, mortality, and histopathological alterations in the gallbladder wall. Materials and Methods: A total of 85 patients were retrospectively divided into three groups: early period LC group (48-72 h; n=30), moderate period LC group (72 h-6 weeks; n=25), and delayed period LC group (6-8 weeks; n=30). Results: The operation time was significantly shorter, and the total number of complication rates and hospital readmission was significantly less frequent in the early period LC group (p<0.05). Ultrasound showed a significantly thicker gallbladder wall (>3 mm) in the moderate and late period LC groups than in the early period LC group (p<0.001). Culture growth was significantly higher, and fibrosis/collagen deposition in the gallbladder wall with injury to the mucosal epithelium was significantly more frequently detected by histopathological examination in the moderate and late period LC groups than in the early period LC group (p<0.05). Conclusion: Early period LC following stone extraction by ERCP is associated with shorter operation time, fewer fibrotic changes in the gallbladder, and lower risk for the development of complications. Therefore, LC can be performed safely in the early period after ERCP.

Background: Recent data have suggested that upfront cholecystectomy should be performed even in the presence of moderately abnormal liver function tests (LFTs). As a consequence, more common bile duct (CBD) stones are discovered on intra-operative cholangiogram. We assessed the presentation and management of such patients to refine their management plan. Methods: Adult patients (>16 years) with an acute gallstone-related disease who had undergone same-stay cholecystectomy from January 2013 to January 2015 were retrospectively assessed. We excluded patients with pre-operative endoscopic CBD exploration. Results: Among the 612 patients with same-stay cholecystectomy, 399 patients were included in the study, and 213 were excluded because of a pre-operative CBD exploration. Fifty patients (12.5%) presented an image of CBD stone on the intra-operative cholangiogram. Such patients were younger (47 vs. 55 years, P = .01) and less likely to present with fever (1 vs. 11.7%, P = .04) or signs of cholecystitis on ultrasound (66 vs. 83.7%, P = .003). Admission LFTs were higher in patients with an image of a stone. Among the 50 patients with an image on cholangiogram, a stone was confirmed in 26 (52%). Most patients (n = 32) underwent post-operative assessment with endoscopic ultrasound (EUS). LFTs did not predict the presence of a confirmed stone. However, the absence of contrast passage into the duodenum was negatively associated with a confirmed stone (P = .08), and a filling defect was positively associated with one (P = .11). Most confirmed stones were successfully extracted by endoscopic retrograde cholangiopancreatogram (ERCP) (25/26, 96%), except in one patient who needed a per-cutaneous approach because of duodenal diverticuli. Conclusions: Same-stay cholecystectomy can (and should) be performed even in the presence of moderately abnormal liver function tests. The cholangiogram suspicion of a CBD stone is confirmed in only half of the patients (more often in the presence of a filling defect, and less often with the absence of contrast passage). All stones can be safely treated after surgery (most by ERCP).
7251 Natural history of asymptomatic bile duct stones at time of cholecystectomy
Gastrointestinal Endoscopy, 2000
Objectives: There is little data on the natural history of asymptomatic bile duct stones and hence there is uncertainty on the management of asymptomatic bile duct stones discovered incidentally at the time of laparoscopic cholecystectomy. We retrospectively reviewed a group of patients who had previously underwent laparoscopic cholecystectomy, but who did not have a pre-operative suspicion of intra-ductal stones, to determine if any biliary complications had subsequently developed.A group of patients who had no pre-operative suspicion of intra-ductal stones, but routinely underwent intraoperative cholangiogram (IOC) at time of cholecystectomy, served as the control group. Methods: A telephone questionnaire was completed by each patient's family practitioner in 59 of 79 (75%) patients who underwent laparoscopic cholecystectomy. In the remaining 20 patients additional information was obtained from hospital records and from the central services agency (CSA). These patients had no pre-operative suspicion of bile duct stones and therefore did not undergo an IOC or ERCP. The control group (73 patients) had no pre-operative suspicion of bile duct stones but had a routine IOC performed to define the biliary anatomy. Results: 59 patients were followed up for an average of 57 months (range 30 -78 months) after laparoscopic cholecystectomy. None of these patients developed pancreatitis, jaundice, deranged liver function tests (LFT's), or required ERCP or other biliary intervention. In the additional 20 patients where no information was available from the family practitioner, 11 patients had follow up appointments with no documentation of biliary complications or abnormal LFT's. 19 of 20 patients were traceable through the CSA and were all alive. Only 1 patient was untraceable and therefore unknown if biliary complications had developed. In the control group, 4 of 73 (6%) patients had intraductal stones detected and extracted. Thus the prevalence of asymptomatic bile duct stones during the time of cholecystectomy in our population was 6%. Conclusions: Asymptomatic bile duct stones discovered at the time of cholecystectomy do not appear to cause any biliary complications over a 5-year follow up. Incidental bile duct stones found in patients undergoing laparoscopic cholecystectomy may not need to be removed.

No procedure has yet been identified as the standard for the detection and management of choledocholithiasis in patients undergoing laparoscopic cholecystectomy. A prospective study involved 1305 patients undergoing elective laparoscopic cholecystectomy. Intravenous cholangiography was performed on all patients except those with jaundice or cholangitis, acute pancreatitis, or allergy to contrast material. Patients underwent endoscopic retrograde cholangiography (ERC) and endoscopic sphincterotomy when there was a strong suspicion of choledocholithiasis, positive or inconclusive findings on intravenous cholangiography or allergy to contrast material with signs of possible choledocholithiasis. Intraoperative cholangiography was performed when patients did not undergo ERC or intravenous cholangiography and whenever the surgeon was in doubt about biliary anatomy or biliary clearance. Two hundred thirty-one patients (17.7%) were referred for preoperative ERC; 14 of them were referred for open surgery because of failure of ERC or sphincterotomy. Only 54 patients underwent intraoperative cholangiography. Bile duct stones, detected in 186 cases (14.2%) (68 of which were asymptomatic), were removed before surgery in 162 cases (87.1%) and during surgery in 20 (10.7%). Self-limited pancreatitis occurred in 3.6% of the patients after sphincterotomy. Laparoscopic cholecystectomy was performed in 98.7% of the cases. The conversion rate was 8% if sphincterotomy had been performed previously, and 3% after standard laparoscopic cholecystectomy (p < 0.001). The morbidity rate was 5% and the mortality rate 0.08%. During the follow-up period 4 patients had retained stones that were treated endoscopically. Preoperative ERC followed by laparoscopy is the best approach to treatment of patients with cholecystolithiasis and suspected choledocholithiasis.
Prediction of Common Bile Duct Stones by Noninvasive Tests
Annals of Surgery, 1999
To define accurate and useful predictors of common bile duct stones (CBDS). Summary Background Data The ability to predict CBDS with noninvasive tests can avoid unnecessary, costly, or risky procedures. Methods All patients referred for examination for CBDS by endoscopic ultrasonography (EUS) from 1993-1996 were prospectively entered in a database. In a first sample selected randomly from the whole population, predictors of CBDS were determined by univariate analysis and logistic regression. Predictors were subsequently tested in that sample and in the rest of the population. A separate analysis was done for patients planned for cholecystectomy. Results Eight hundred and eighty patients (328 men, 552 women), aged 57.8 ± 17 years (range 16-94), were included. The prevalence of CBDS was 18.8%. Age, serum levels of bilirubin, aspartate aminotransferase, alanine aminotransferase, gamma-glutamyl transferase (GGT), and alkaline phosphatase, and the existence of jaundice and fever, a dilated bile duct, and a pathologic gallbladder were found to be associated with CBDS. Logistic regression was undertaken separately for patients younger than 70 years (predictors: GGT >7xnormal; pathologic gallbladder; dilated bile duct) and older than 70 years (predictors: GGT >7xnormal; fever > 380C; dilated bile duct). Odds ratios were 3 to 6.7. The model was satisfactorily applicable to the second sample; age <70 years: x2 = 3.3 (NS); age >70 years: x2 = 3.8 (NS). In patients younger than age 70 and planned for cholecystectomy, the combination of the level of GGT and dilated bile duct predicted CBDS accurately. Conclusions A simple screening of patients at risk for CBDS can be achieved with three predictive criteria adapted for the patient's age. Gallstone disease is a very common condition involving roughly 15% of the population in Europe and Northern America.1 In 10% to 15% of cases, cholelithiasis is complicated by the presence of common bile duct stones. Although there is no consensus on this point, many investigators believe that ductal stones should always be removed because of the high risk of complications such as cholangitis or acute pancreatitis.24 The circumstances in which common duct stones are revealed can be schematized as follows:

Background: Approximately 10% of patients with symptomatic gallstones may have associated common bile duct stones (CBDS). However, the predictive value of noninvasive tests as well as the preoperative diagnosis and management of CBDS have not been well defined. The aim of this study was to define an accurate and simple model for the prediction and management of CBDS. Methods: A prospective database containing 986 cholecystectomies performed from 1994 through 1999 was evaluated. Univariate analysis using the Pearson chi-square test was performed to determine the factors significantly related to the presence of CBDS. Then logistic regression analysis was performed for multivariate analysis to discover independent predictors. Results: Of the 986 patients in this study, 48 (5%) had CBDS. Of the 48 patients with choledocholithiasis, 22 (46%) were men and 26 (54%) were women. The mean age was 55.3 years (range, 16-87 years). As a result of multivariate analysis, abdominal ultrasonographic findings suggestive of CBDS (common bile duct diameter exceeding 8 mm or visible stones), total bilirubin, and gamma glutamyl transpeptidase levels above normal were the independent predictors of CBDS in patients age 70 or younger. On the other hand, an elevated bilirubin level was found to be the single independent factor related to CBDS in the elderly. Conclusions: For patients with gallstones, suggestive ultrasonographic findings in those younger than 71 years and elevated direct or total bilirubin level in those older than 70 years are the most valuable and practical predictors of CBDS, and thus are the proper indications for preoperative endoscopic retrograde cholangiography.

Introduction: Intraoperative cholangiography (IOC) during laparoscopic cholecystectomy (LC) is valuable in the detection of biliary abnormalities. In this study, we aimed to investigate the diagnostic accuracy of IOC during LC for the detection of anatomic variations of the biliary system, as well as the visualization ability of IOC on determining the normal anatomy of the biliary tree. Materials and methods: This cross-sectional study was conducted on patients who were presented to the surgery outpatient clinic and were scheduled for elective LC for symptomatic cholelithiasis. Patients underwent intraoperative laparoscopic ultrasound (LUS) before the dissection of Calot's triangle and IOC video fluoroscopy examination of the extrahepatic biliary tree. Results: Our study enrolled 53 patients. No intraoperative complications occurred in all enrolled patients. LUS was successful in all 53 (100%) cases, while IOC was successful in 50 (94.3%) cases. IOC had accuracy rate of 100% (50 patients) in defining biliary ducts at the porta hepatis compared to 84.91% (45 patients) for LUS with a failure rate of 15.09% (p = 0.60). Concerning stones detection, LUS accuracy indexes were as follows: sensitivity = 80%; specificity = 95.83%; positive predictive value (PPV) = 66.67%; negative predictive value (NPV) = 97.87% 99; and diagnostic odds ratio (DOR) = 92. IOC accuracy indexes were as follows: sensitivity = 80%; specificity = 93.33%; PPV = 57.14%; NPV = 90%; and DOR = 56. Conclusion: The results of the current study encourage using IOC as an effective, accurate, feasible, and safe technique to visualize the biliary tree while performing LC.
