Surgeon-Performed Percutaneous Endoscopic Biliary Lithectomy: Description of a Novel Technique and Initial Results

Percutaneous endoscopic biliary lithectomy (PEBL) can be performed through preexisting drain tracts, offering ductal clearance and definitive management for patients with complicated gallstone disease unable to undergo conventional therapy. The technique has not been widely adopted by general surgeons. Herein, we describe our technique with surgeon-performed PEBL and present initial results. A single institutional retrospective review of the electronic medical record was performed for patients who underwent percutaneous choledochoscopy between February 2019 and November 2020. All operations were performed by 1 of 2 board-certified general surgeons with fellowship training in surgical endoscopy. Preoperative, operative, and postoperative variables were analyzed using descriptive statistics. Thirteen patients underwent PEBL. Seventeen total procedures were performed; 4 patients underwent repeat intervention. The diagnoses leading to PEBL were: cholelithiasis (8), choledocholithiasis (4), and recurrent pancreatitis (1). Complete ductal clearance was achieved in 9 patients (69.2%) during the initial procedure. The remaining 4 patients (30.8%) underwent repeat PEBL, at which point complete ductal clearance was then achieved. The percutaneous drain was removed at the time of final procedure in 5 patients (38.5%) or within 5 weeks in the remaining 8 (61.5%). No intraoperative complications occurred, and no pancreatic or biliary postoperative complications or recurrences were noted with a mean follow-up of 279 ± 240 days. Surgeon-performed PEBL is a safe and effective method of achieving biliary ductal clearance. The technique is readily achieved following basic endoscopic and fluoroscopic principles and should be understood by all physicians managing gallstone disease.
