Multimodal Endoscopic Management of Fistula after Sleeve Gastrectomy Involving a Novel Esophageal Stent

The Luso-Cor esophageal stent is a specifically designed covered metallic stent with a 5-mm uncovered ring near the proximal edge, which reduces the risk of migration. Two articulating zones in the middle portion allow better adaptation to altered anatomy after LSG and a distal flare reduces retrograde reflux of fluid. This stent overcomes strictures in the gastric tube, concomitantly present in nearly 50% of patients with fistulas after LSG. The novel Luso-Cor esophageal stent provided a bridge to clinical stability with a significant reduction in the size of the fistula orifice which was closed with complementary therapeutic endoscopic procedures.
