Event Description

This file is being created to cover a complaint reference in the study: ¿fully-covered esophageal stent migration rates in benign and malignant disease: a multicenter retrospective study¿.The rate of clinically relevant migration as defined by stent migration followed by reintervention via endoscopy for stent replacement is unknown.The goal of this study is to gain insight into the total migration rate and clinically relevant migration rate of different types of fcsems placed within benign and malignant strictures with specific attention paid to stent manufacturer, diameter, and length.Multicenter retrospective analysis of endoscopic data from patients with fcsems placed within benign or malignant strictures.A total of 369 patients were included, 161 of whom had benign strictures and 208 of whom had malignant strictures.Replacement of a stent is indicated based on the degree of migration as well as clinical symptoms (i.E.Recurrence of dysphagia, pain, etc) and thereby an inability for the stent to perform its intended function, which we define as clinically relevant migration.The evolution stent (cook medical) which accounted for 55 (15%) of the stents placed.This file is being opened to address: "a total of 208 fscems were placed for malignant strictures (35 of the 208 devices were cook evolution devices).Of the 208 fully-covered self-expanding metal stents (fcsems), a total of 30 (14 %) were noted to have a late complication that required stent replacement.Two stent¿s which were placed for malignant strictures were replaced due to other non-defined complications.As the study does not detail which manufacturer's stents resulted in the other non-defined complications, this complaint has been logged as there is a possibility the stent's were cook evolution device's.
