Optimal Timings of Laparoscopic Cholecystectomy After ERCP in Patients With Gallstones Along With CBD Stones

This randomized controlled trial aims to compare the mean operative time and outcomes of early versus delayed laparoscopic cholecystectomy after ERCP in patients with cholelithiasis and choledocholithiasis. Patients will be randomized into two groups: early cholecystectomy (within 72 hours of ERCP) and delayed cholecystectomy (≥1 month after ERCP). Outcomes include operative time, intra-operative blood loss, hospital stay, and conversion to open cholecystectomy

Prophylactic PS Placement to Prevent Pancreatitis After Endoscopic Transpapillary GPC for Cholelithiasis With Concomitant Choledocholithiasis

In this multicenter, randomized trial, patients with cholelithiasis with concomitant choledocholithiasis based on inclusion and exclusion criteria will be randomly assigned to receive rectal indomethacin alone or the combination of indomethacin plus a prophylactic pancreatic stent after endoscopic transpapillary gallbladder-preserving cholecystolithotomy.Clinical data and patient-reported outcomes are regularly collected at baseline and during follow-up periods. The study aims to analyze the impact of pancreatic duct stent implantation on the incidence of post-ERCP pancreatitis in gallstone patients treated with ERCP-GPC by comparing the efficacy differences between the experimental and control groups. Additionally, the study investigate the effects of pancreatic duct stent placement post-ERCP on other postoperative complications, conduct a comparative analysis of the economic benefits of placing versus not placing pancreatic duct stents after ERCP, and develop effective clinical strategies for preventing pancreatitis after gallbladder-preserving stone extraction in gallstone patients.

Treatment Outcomes and Complications of Three Therapeutic Approaches for Concomitant Choledocholithiasis and Cholecystolithiasis

Recruit patients with cholelithiasis with concomitant choledocholithiasis into the cohort, and assign them to undergo endoscopic transpapillary gallbladder-preserving cholecystolithotomy or ERCP plus laparoscopic cholecystectomy or conservative treatment based on patient preference. Collect clinical data and patient-reported outcomes regularly at baseline and during follow-up in the cohort. Assess the clinical safety of ERCP-GPC and LC by evaluating the clinical success rate of treatment as well as the incidence of short-term and long-term postoperative complications; investigate the efficacy differences among endoscopic transpapillary gallbladder-preserving cholecystolithotomy or ERCP plus laparoscopic cholecystectomy or conservative treatment in managing cholelithiasis with concomitant choledocholithiasis.
