LAPAROSCOPIC EXPLORATION OF THE COMMON BILE-DUCT - LESSONS LEARNED FROM 129 CONSECUTIVE CASES

Since the introduction of laparoscopic cholecystectomy there has been widespread debate about the best way to manage common bile duct (CBD) calculi. Between August 1991 and July 1994, 129 patients underwent laparoscopic exploration of the CBD. Fifteen patients of median age 52 years were managed by glucagon-induced relaxation of the sphincter of Oddi and saline flushing of the bile duct through a cholangiogram catheter. This had a success rate of 73 per cent and took a median of 90 min including cholecystectomy. The technique has now been replaced by Dormia basket exploration of the CBD. Transcystic common duct exploration using a Dormia basket was used in 79 patients of median age 47 years. Duct clearance was achieved in 96 per cent of cases with a median operating time of 55 min. Thirty-five patients of median age 52 years were managed by choledochotomy and T tube placement, with a 91 per cent duct clearance rate and a median operating time of 120 min. Overall duct clearance was achieved in 92 per cent of patients with an operative morbidity rate of 5.4 per cent. Duct clearance using either a Dormia basket or choledochotomy and T tube placement was obtained in 95 per cent of patients. Laparoscopic exploration of the CBD is an important alternative in the management of common duct calculi.
