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.
