Abstract

Background Percutaneous drainage is a first-line treatment for bilomas developed post-cholecystectomy in the setting of bile leak from the cystic duct stump. Percutaneous drainage is usually followed by surgical or endoscopic treatment to address the leak. Aims This study aimed to evaluate outcome of selective coil embolization of the cystic duct stump via the percutaneously placed drainage catheters in patients with post-cholecystectomy bile leak. Methods Seven patients with persistent bile leak after laparoscopic cholecystectomy who underwent percutaneous catheter placement for biloma/abscess formation in the region of the gallbladder fossa were followed. These patients underwent selective trans-catheter cystic duct stump coil embolization from Feb 2013 to Feb 2019. Procedural management, complications, and success rates were analyzed. Results All patients underwent placement of a percutaneous catheter for drainage of biloma formation in the gallbladder fossa post-cholecystectomy. Selective coil embolization of the cystic duct was performed through the existing percutaneous tract on average 3.5 weeks after percutaneous catheter placement, resulting in resolution of the biloma. All bile leaks were immediately closed. None of the patients showed recurrent bile leak or further clinical symptoms. Coil migration to the common bile duct was diagnosed in a single case, after 2.5 years, with no bile leak reported. Conclusions Selective trans-catheter coil embolization of the cystic stump is a feasible and safe procedure, which successfully seals leaking cystic duct stumps and can circumvent the need for repeat surgical or endoscopic intervention in selected patient populations.
