Purpose: To demonstrate the feasibility of cystic duct embolization and chemical gallbladder ablation as an alternative to cholecystectomy in high-risk patients with calculous cholecystitis who were not candidates for surgery.
Materials and methods: This prospective study included 10 patients with acute cholecystitis (7 males and 3 females) aged 70-91 years (average age, 81.6 years) between 2013 and 2019. A cholecystostomy catheter was inserted during the acute phase, followed by cystic duct coil embolization performed via the existing drainage tube tract. Once asymptomatic, 3% aethoxysklerol was injected into the gallbladder, and the drain was removed upon sonographic confirmation that the gallbladder remained contracted. Each phase of the procedure was performed with an interval of 2-3 weeks. Clinical, cholangiographic, and sonographic data were collected before and after drain removal at 1-month follow-up.
Results: Cystic duct embolization was technically successful in all patients, with no immediate post-procedure complications. Gallbladder ablation performed in 10 patients was technically successful in all of them (median follow-up, 11 months). One patient required repeat ablation at 14 months, and the prolonged biliary excretions of 1 other patient ceased only at 8 months.
Conclusions: Cystic duct embolization with gallbladder ablation is a feasible procedure for patients in whom cholecystectomy is contraindicated.
