Suture-loop anchoring at the distal end of a pancreatic stent: a novel approach to prevent proximal migration

Proximal migration of pancreatic stents, though rare (0.2%) ¹ , remains a serious complication of endoscopic retrograde cholangiopancreatography (ERCP) that requires complex retrieval methods including endoscopic grasping, pancreatoscopy, or surgery ² . Recent advances include endoscopic ultrasound (EUS)-guided retrieval ³ , yet these approaches demand expertise and resources.

We propose an innovative preventive strategy. An absorbable suture is threaded through the terminal side hole, and the length of the suture after knotting is kept at approximately 3 cm ( Fig. 1 a ). The video documents a 78-year-old jaundiced patient in whom a trainee inadvertently deployed a 5-Fr stent deeply into the pancreatic duct ( Fig. 1 b ). The supervising physician grasped the externalized suture with rat tooth forceps ( Fig. 1 c , Video 1 ), successfully repositioning the stent ( Fig. 1 d ) and enabling subsequent biliary stenting. This suture-loop technique provides a simple yet reliable solution for preventing pancreatic stent migration. The technique is particularly suitable for trainees and is recommended for widespread clinical adoption.
