Laparoscopic cholecystectomy: imaging of complications and normal postoperative CT appearance.

Six patients underwent imaging studies to evaluate complications related to laparoscopic cholecystectomy. In addition, computed tomography (CT) of the abdomen and pelvis was performed on six patients 3-5 days after uncomplicated laparoscopic cholecystectomy in order to further clarify the normal postoperative CT appearance in these patients. Complications included ureteral laceration with periureteric hematoma and ureteroperitoneal fistula, hepatic artery pseudoaneurysm, hepatic laceration, retained common bile duct stone, bile leak, and biloma of the abdominal wall. At 3-5 days following uncomplicated laparoscopic cholecystectomy, typical CT findings include fluid density in the gallbladder fossa, a very small amount of pelvic fluid, and small densities within the subcutaneous fat at the expected sites of trocar insertion.
