Percutaneous Cholangioscopic Laser Successfully Removes Migrated Biliary Suture Causing Stones

Percutaneous cholangioscopic laser lithotripsy safely removed an intraductal suture acting as a nidus for recurrent intrahepatic cholelithiasis. The minimally invasive approach avoided surgical revision. This was a single case report.

• Design: Single case report describing a technique for removing a migrated surgical suture nidus.
• Key Finding: Successful endoscopic laser fragmentation and extraction of the stone-suture complex via a percutaneous transhepatic tract.
• Limitation: N of 1 case; generalizability and long-term stone recurrence rates are unknown.
