Abstract
BACKGROUND AND AIMS: Fully covered self-expandable metal stents (FCSEMSs) are a common therapeutic treatment for benign and malignant esophageal disorders. Stent migration is a common adverse event of FSCEMSs. We describe clips with anchor prongs (CAPs) as a novel technique to reduce FCSEMS migration. METHODS: We retrospectively analyzed 27 patients with FCSEMSs affixed with CAPs and 28 patients without FCSEMS affixation for stent migration as the primary endpoint and used previously published data to determine the relative risk reduction (RRR). RESULTS: Migration was observed in 14.8% of cases (RRR, 43%). CAP affixation was associated with a decreased odds of migration (odds ratio, .19; P = .02). The only adverse event reported in those with (n = 4) or without (n = 14) CAP fixation was postprocedural pain. CONCLUSIONS: CAPs may reduce stent migration, providing a novel option for the endoscopist seeking a means of securely attaching esophageal FCSEMSs.
