Direct peroral cholangioscopic retrieval of an inward migrated plastic stent lodged in the cystic duct and liver hilum.

Endoscopic sphincterotomy and stone extraction are widely performed as a primary intervention for patients with common bile duct (CBD) stones, with or without cholangiosepsis, with a high success rate and a relatively low complication rate [1]. When CBD stone removal is not successful, a plastic stent can be placed as a salvage therapy to achieve drainage, especially in the septic patient. [Extracted from the article]
