Comparison of laparoscopic common bile duct exploration and endoscopic retrograde cholangiopancreatography combined with laparoscopic cholecystectomy for patients with gallbladder and common bile duct stones a meta-analysis of randomized controlled trials

OBJECTIVE: This study aimed to compare the efficacy and safety of laparoscopic common bile duct exploration (LCBDE) and endoscopic retrograde cholangiopancreatography (ERCP) combined with laparoscopic cholecystectomy (LC) to determine which one provides a better outcome for patients with gallbladder and common bile duct stones. MATERIALS AND METHODS: An electronic literature search was undertaken using Embase, Medline, PubMed, and Cochrane Library databases up to April 2022. For quality assessment of included studies, randomized controlled trials (RCTs) were assessed by utilizing the Jadad scale. The primary outcome includes surgical success rate, retained stone rate, stone clearance rate, major morbidity, and mortality. The second outcome includes conversion to open surgery rate, postoperative pancreatitis, bile leakage, cholangitis, hemorrhage, pneumonia, and surgical-site infection. RESULTS: 14 randomized controlled trials with 2,181 patients were included. No significant difference was seen between the two groups in terms of surgical success, stone clearance, retained stones, operation time, and total morbidity. LC-LCBDE had higher rate of bile leakage [relative risk (RR): 4.52; 95% confidence interval (CI): 2.19-9.31] and lower rate of postoperative pancreatitis (RR: 0.25; 95% CI: 0.13-0.46), cholangitis (RR: 0.17; 95% CI: 0.05-0.67), and hemorrhage (RR: 0.18; 95% CI: 0.07-0.42). CONCLUSIONS: Both LC+LCBDE and LC+ERCP are safe, effective, and minimal-invasive treatments for concomitant gallbladder and CBD stones. LC-LCBDE was associated with comparable effects compared with LC+ERCP in terms of surgical success rate, stone clearance rate, retained stones rate, operation time, and total morbidity. At the same time, LC-LCBDE had a higher rate of bile leakage and a lower rate of postoperative pancreatitis, cholangitis, and hemorrhage. [ABSTRACT FROM AUTHOR]
