Endoscopic retrograde cholangiopancreatography (ERCP) of surgically altered gastrointestinal anatomy (SAA) remains technically challenging. ERCP perforation rates in SAA are 2–5% 1 . Endoscopists should familiarize themselves with troubleshooting techniques to effectively manage these complications.

A 69-year-old male with a history of distal gastrectomy followed by Roux-en-Y reconstruction presented 2 months postoperatively with acute pancreatitis owing to common bile duct stones (CBDs). Pancreatitis resolved conservatively, and elective management of the residual CBDs was planned.

ERCP was performed using a single-balloon enteroscope (SIF-H290S; Olympus, Tokyo, Japan). Multiple CBDs were visualized and extracted using cholangiography and an endoscopic mechanical lithotripsy device, respectively ( Fig. 1 ).

However, while attempting to extract residual stones using a balloon catheter, inappropriate endoscopic manipulation caused extensive mucosal lacerations and perforations. The mucosal laceration and subsequent perforation were attributed to excessive traction and rotational manipulation of the endoscope during balloon catheter-assisted stone extraction. Although such maneuvers are commonly performed during endoscopic removal of CBDs with a side-viewing duodenoscope, they are not necessarily required in procedures involving SAA.

Owing to the fragile and ischemic nature of the injured mucosa, initial closure attempts using clips were inadequate. A traction clip technique using silicone bands (SureClip Traction Band; Micro-Tech, China) was employed because of the high risk of complete closure failure and/or delayed perforation expansion 2 . Traction was initially established between two healthy mucosal sites away from the perforation using traction clips to create a stable base. Additional clips were sequentially placed, enabling robust closure of the defect without exacerbating tissue injury ( Fig. 2 , Fig. 3 , Fig. 4 , Video 1 ). Complete suturing was safely performed. Clinical management with conservative therapy resulted in a successful recovery without further complications.

Previous studies have described various endoscopic techniques using traction clips for gastrointestinal defect closure, particularly after endoscopic submucosal dissections 2 3 . The traction clip technique reduces tension at the closure site, facilitates healthy tissue approximation, and enhances repair durability. This method may reduce the risk of delayed perforation, particularly in thin-walled structures, including the small intestine. Our experience suggests that this technique is particularly beneficial for managing ERCP-related small-bowel perforations in patients with SAA.
