Methods
ESOPHAGEAL PERFORATION
For this multicenter retrospective cohort study, we included all adult patients primarily treated with EVT for esophageal perforations, between January 2018 and October 2021, at five European tertiary referral centers. Presence of a perforation was based on computed tomography (CT) scan and/or contrast swallowing examination and/or an endoscopic finding of a defect in the esophageal wall.Demographic and clinical data were retrospectively retrieved from electronic patient files.The study was assessed by the local medical ethics committees, who waived the need for formal ethical review.
