RESUMO
Introduction: Dynamic changes in liver function tests have been proposed to correctly reclassify the risk of choledocholithiasis; however, information is scarce and insufficient to recommend its use. Methods: Retrospective cohort of patients undergoing endoscopic retrograde cholangiopancreatography (ERCP) due to moderate and high risk of choledocholithiasis according to the 2019 American Society of Gastrointestinal Endoscopy (ASGE) guidelines. We evaluated whether significant changes in liver function tests (bilirubin, transaminases, or alkaline phosphatase), defined as an increase or a reduction ⩾30 or ⩾50% between two measurements taken with a difference of 24-72 h can correctly reclassify the risk of choledocholithiasis beyond the ASGE guidelines. The net reclassification index (NRI) was calculated for patients with and without choledocholithiasis. Results: Among 1175 patients who underwent ERCP, 170 patients were included in the analysis (59.4% women, median 59.5 years). Among patients without a diagnosis of choledocholithiasis, the number of patients correctly reclassified by transaminases was slightly higher than those incorrectly reclassified (NRI = 0.24 for aspartate amino transaminase and 0.20 for alanine amino transaminase). However, among patients with a diagnosis of choledocholithiasis, it led to incorrect reclassification in a greater number of cases (NRI = -0.21 and -0.14, respectively). The benefits of reclassification were minimal for bilirubin and alkaline phosphatase, or for value changes >50%. A subgroup analysis showed similar findings in patients without a history of cholecystectomy and in those with normal bile duct. Conclusion: Dynamic changes in liver function tests do not improve choledocholithiasis risk classification beyond the 2019 ASGE criteria. New criteria should continue to be sought to optimize risk stratification.
RESUMO
BACKGROUND: Choledocholithiasis is a common complication of cholelithiasis, occurring in up to 18% of patients. Multiple treatments are often performed during the course of the management of choledocholithiasis, sometimes without success. Our study was performed identify the factors predictive of the success of treatment with retrograde endoscopic cholangiopancreatography (ERCP). METHODS: This was a retrospective, case-control study that used data from a biliary disease database at Hospital de Clínicas de Porto Alegre (HCPA). Demographic, clinical, radiological and procedure-related variables were compared between patients with successful biliary clearance after one ERCP procedure (Group 1) and those with unsuccessful biliary clearance after one ERCP procedure (Group 2). RESULTS: Three hundred twenty patients were included in Group 1, while 254 were included in Group 2. Multivariate analysis showed that older age, previous biliary exploration, elevated serum total bilirubin, choledocholithiasis above the level of the confluence of the hepatic ducts, stones retained in the cystic duct or Mirizzi syndrome, dilatation of the bile duct diagnosed during ERCP, and the need for suprapapillary opening were independently associated with the failure of the first ERCP to achieve bile duct clearance. The performance of imaging at the same institution prior to the procedure and the retention of stones in the duodenal papilla were associated with the success of endoscopic treatment. CONCLUSIONS: The variables identified in this study, when considered in conjunction with the results of previously published studies, can be used to guide the choice of therapeutic methods for patients with choledocholithiasis in the future, given the significant difference in outcomes between the two groups. In the future, a prospective study should be performed to determine whether the same factors are predictive of the success of other methods of treatment (surgical or percutaneous).

Surgical clip migration into the common bile duct (CBD) is a rare complication after laparoscopic cholecystectomy (LC). Few cases of surgical clip migration have been reported in the literature, and most of them have been successfully treated with endoscopic retrograde cholangiopancreatography (ERCP). We present a 71-year-old woman with 48 h of abdominal pain, jaundice and fever 6 years after laparoscopic cholecystectomy. She was diagnosed with common bile duct obstruction from surgical clip migration. After failure of ERCP, the patient was successfully treated with an innovative approach by laparoscopic transcystic extraction using endoscopic hose-type biopsy forceps. The presented technique was feasible and safe in expert hands, representing a valuable alternative to avoid the need of a choledochotomy in patients with unsuccessful ERCP.
RESUMO
Background: Despite the effectiveness of laparoscopic common bile duct (CBD) surgery, no case series details the use and advantages of laparoscopic CBD exploration (LCBDE) without use of intraoperative cholangiography (IOC) in endoscopic retrograde cholangiopancreatography (ERCP) failure. Therefore, we present a case series regarding our success with LCBDE in managing CBD stones (CBDSs) using laparoscopic technique without IOC. Materials and Methods: We performed a descriptive retrospective observational study. Patients with CBDSs, alone or along with gallbladder stones, were treated through LCBDE with primary CBD closure after failed ERCP. Results: All patients underwent LCBDE with choledocotomy and primary duct closure. Patients with gallbladder stones underwent laparoscopic cholecystectomy (78%). All procedures were successful, and no conversions occurred. Surgery duration averaged 106 minutes. Intraoperative bleeding averaged 15 cc, and no mortalities occurred. No patients required additional surgery or intensive care unit admission. Hospitalization duration averaged 5 days. Conclusions: Therefore, a laparoscopic approach with primary CBD closure after failed ERCP for complex CBDSs is safe and effective.
