Transcystic Laparoscopic Common Bile Duct Exploration for Pediatric Patients with Choledocholithiasis

What This Study Found

A multi-center US retrospective study from 2018 to 2022 compared two approaches to suspected common bile duct stones in children: transcystic laparoscopic common bile duct exploration versus ERCP as the initial intervention 0:09 0:09. Among 252 pediatric patients, 156 underwent the transcystic laparoscopic approach and 96 had ERCP first 0:28 0:28 0:38. The laparoscopic group had significantly fewer complications and shorter hospital stays 0:38 0:38.

Why This Matters for Your Practice

The traditional adult paradigm—ERCP first for choledocholithiasis—may not serve pediatric patients best. This study suggests that when a child needs cholecystectomy for gallstone disease and imaging raises concern for common bile duct stones, proceeding directly to laparoscopic exploration through the cystic duct offers better outcomes than pre-operative ERCP 0:38 0:38. The transcystic approach addresses both the gallbladder and the duct stones in one operation, avoiding the procedural risks and recovery time of a separate endoscopic intervention.

What Remains Uncertain

The study does not specify which complications drove the difference between groups, nor does it detail stone characteristics, duct anatomy, or technical success rates that would help predict when the transcystic approach is feasible. The retrospective design means selection bias likely influenced which patients went to each pathway—surgeons may have reserved ERCP for cases they judged unsuitable for laparoscopic exploration.

Implications for Referral and Management

For primary care and emergency physicians managing a child with right upper quadrant pain and imaging suggesting both cholelithiasis and choledocholithiasis, this evidence supports direct surgical referral rather than assuming ERCP must come first. For pediatric surgeons, the data argue for attempting transcystic exploration as the initial approach when the anatomy appears favorable 0:52. The ERCP-first strategy remains appropriate when laparoscopic expertise is unavailable or when the clinical picture suggests ERCP offers diagnostic or therapeutic advantages the surgeon cannot provide, but it should not be reflexive.
