A fully covered metal bariatric stent is utilized for the treatment of fistulas in gastric sleeve surgeries. It is available in three sizes: 18, 21, and 24 centimeters, and comes in two models: standard and chemotactic. This unique stent design effectively prevents stent migration by featuring a diameter of 28 millimeters at its center and 32 millimeters at both ends. It is coated with silicone along its length, which serves the dual purpose of preventing tissue ingrowth into the stent and providing coverage for any fistulas or damage, promoting optimal healing.
