A case of a 79-year-old man, status post laparoscopic cholecystectomy with a drainage catheter placed at the gallbladder fossa is presented. The case was complicated postoperatively by abdominal pain and bilious discharge from the drainage catheter. Endoscopic retrograde cholangio-pancreatography demonstrated leakage through the cystic duct stump into the gallbladder fossa. Placement of a covered metal stent endoscopically failed to seal the leak. We performed percutaneous embolization of the cystic duct stump using a combination of coils and gelatin sponge through the drainage catheter in the gallbladder fossa. To our knowledge, this technique has not been previously described in the literature.
