title: Imaging of complications of laparoscopic cholecystectomy.
abstract: Laparoscopic cholecystectomy has gained widespread acceptance for treatment of cholelithiasis. Because radiologists have a primary role in recognizing and treating complications of this surgical technique, we reviewed the clinical records and imaging studies of 29 patients with complications after laparoscopic cholecystectomy. Complications included bile duct injuries (15 cases), retained common bile duct stones (seven cases), cystic duct stump leak (four cases), bowel perforation (two cases), abdominal abscess (two cases), intraperitoneal gallstones (2), and failure to diagnose malignant bile duct obstruction (one case). Twenty-two patients required reoperation, and one patient with bowel perforation died. Eleven of 15 bile duct injuries were imaged prior to hepaticojejunostomy. Nine of 11 were proximal bile duct injuries within 2 cm of the junction of the right and left bile ducts. Endoscopic retrograde cholangiography (ERC) identified the distal extent of injuries, but transhepatic cholangiography (THC) was necessary to fully evaluate the proximal extent of the bile duct abnormalities. ERC was used for diagnosis and treatment of the seven patients with choledocholithiasis. Abdominal films showed intraperitoneal in one patient with bowel perforation, intraperitoneal stones in a second patient, and intraabdominal abscess in one of two patients in whom abdominal films were performed. Computed tomography (CT), done in three patients with bowel perforation or abscess, showed the one duodenal perforation, and the two abscesses. CT also showed bilomas, intraperitoneal gallstones, and unsuspected malignancy. Imaging studies detected and defined complications after laparoscopic cholecystectomy in all cases.
