A novel multisegmented esophageal fully covered self-expandable metal stent (FCSEMS) was designed to reduce stent migration, which is seen in up to 30% of patients. The goal of this study was to evaluate the safety and efficacy of the multisegmented FCSEMS. This multicenter prospective study aimed to include 30 patients undergoing palliative stent placement. Efficacy, defined as technically successful stent placement and dysphagia scores, and safety, defined as the number of adverse events (AEs) and serious AEs (SAEs), were measured. The study was prematurely terminated due to safety concerns after including 23 patients (mean ± standard deviation age, 72 ± 10 years; 78% male). Stent placement was technically successful in 21 patients (91%), and dysphagia scores had improved in all patients with successful stent placement. SAEs were reported in 16 (70%) patients. Stent-related mortality occurred in 3 patients (13%). The multisegmented FCSEMS successfully treated malignant dysphagia. The study was prematurely terminated, however, because stent placement was associated with a relatively high SAE rate. (Clinical trial registration number: NCT04415463.)
