However, in elderly patients and\u002For those with significant comorbidities, surgery is often not feasible, leaving this population at high risk of biliary event recurrence (approximately 25-31% per year without treatment).\n\nEUS-guided gallbladder drainage (EUS-GBD) using a lumen-apposing metal stent (LAMS) is an established endoscopic technique currently recommended for acute cholecystitis in patients unfit for surgery. It creates an internal fistula between the gallbladder and the adjacent digestive tract, allowing direct endoscopic access for stone clearance (cholecystoscopy). This approach could theoretically prevent biliary event recurrence similarly to cholecystectomy.\n\nThe DRECON study (DRainaige, Endoscopic ultrasound, CONservative) is a multicenter, randomized, comparative clinical trial evaluating whether EUS-GBD with LAMS reduces biliary recurrence at 1 year compared to conservative managment (CM) in patients unfit for surgery after a biliary event without acute cholecystitis who are candidates for elective cholecystectomy.\n\nPrimary hypothesis: EUS-GBD will reduce the risk of biliary event recurrence (biliary colic, acute pancreatitis, cholangitis, choledocholithiasis, or cholecystitis) at 1 year of follow-up compared to conservative management in patients unfit for surgery with gallbladder lithiasis.\n\nEstimated sample: 110 patients (55 per arm).
