Laparoscopic exploration of the common bile duct to relieve choledocholithiasis in children

Abstract

The optimal method of managing paediatric choledocholithiasis is controversial. Endoscopic retrograde cholangiopancreatography (ERCP) and sphincterotomy are effective in adults; however, the long-term outcome in the paediatric population is unknown. We report our experience with laparoscopic common bile duct (CBD) exploration to relieve choledocholithiasis in children and propose a management algorithm. A retrospective chart review of 124 children, who underwent cholecystectomy over 5 years was conducted. Data collected included age at onset, duration of symptoms, length of stay, method of relieving choledocholithiasis and postoperative outcome. Mean age was 12.5 years (range 10-14 years). 102 cholecystectomies were performed laparoscopically. Following intraoperative cholangiogram (IOC), choledocholithiasis was identified in eight patients. In three cases, the CBD was flushed with normal saline via a 5F ureteral catheter successfully relieving the obstruction. In three cases, a Dormia basket was used to break down the stone. Two cases required postoperative ERCP and sphincterotomy to successfully extract the stones. All children were symptom-free at follow-up with no complications reported to date. Laparoscopic CBD exploration with Dormia basket or saline flushes to relieve choledocholithiasis is a safe and effective alternative in children. If unsuccessful, ERCP and sphincterotomy can be performed in centres with adequate resources and expertise.
