Abstract
Background: Extraction of a migrated esophageal stent may be extremely diff icult with a substantial risk of complications including esophageal perfora tion and hemorrhage. Methods: Retrospectively 242 patients were evaluated who underwent implanta tion of self-expanding metal stents (SEMS) and 13 (5.4%) were identified wi th distal stent migration. In all cases of stent dislocation into the stoma ch, extraction of the stent was not attempted and a new stent was inserted. Results: Twelve patients had dysphagia. One patient underwent surgery becau se of stent impaction in the colon, 3 had unrecognized passage of the stent per rectum, and 9 had evidence of the stent into the stomach. Further seve re complications were not observed in any patient and all stents remained i nto the stomach. Conclusion: Complications arising from migrated esophageal stents are uncom mon. Further studies are warranted to determine which patients with migrate d SEMS warrant stent retrieval.
