Abstract
|
|
|
|
Placement of a self-expanding metal stent (SEMS) is effective for palliation of a malignant biliary obstruction. However, metal stents can cause various complications, including stent migration. Distally migrated metal stents can be removed successfully in most cases, particularly covered SEMS. Despite conventional methods, stent trimming using argon plasma coagulation may be helpful in difficult cases. However, no serious complications related to the trimming or remnant stent removal method have been reported due to the limited number of cases. In particular, proximal migration of a remnant fragmented metal stent after stent trimming followed by balloon sweeping has not been reported. We report an unusual case of proximal migration of a remnant metal stent during balloon sweeping following stent trimming by argon plasma coagulation, which was successfully removed with rotation technique using a basket and revised endoscopically.
