Task: Answer Verification
Input (English): Question: Is intraoperative cholangiography essential to avoid duct injuries during laparoscopic cholecystectomy?
Answer: We think that the use of IOC to avoid bile duct injuries is not essential, and that the key to avoiding such injuries is meticulous demonstration of anatomic detail at operation. We have been satisfied with selective use of endoscopic cholangiography and sphincterotomy for the management of choledocholithiasis.
Output (English): no
