摘要： A method of an intestinal protective ostomy with the use of a degradable intestinal diversion device and an intubation includes steps of: preparing the degradable intestinal complete diversion device; after cutting off the terminal ileum intestine, measuring the diameter of the intestine, and then selecting a degradable intestinal diversion device of appropriate specifications according to the diameter of the intestine; when diverting, placing the device in the intestinal cavity, and fixing the ileum on the device with a thread at the convex ring; inserting the stoma drainage tube in the proximal ileum where the device is placed against the direction of intestinal peristalsis; and disintegrating and discharging the device with the contents of the intestine. The invention used with a drainage tube realizes complete intestinal diversion without secondary operations of stoma reintroduction.

摘要： A degradable intestinal complete diversion device, made of biocompatible degradable materials, includes a circular tube constituting the bridge for the intestinal incisions on both sides to crawl towards each other and anastomosed; the end of the circular tube is connected with a gradually expanding flared opening, and a convex ring for binding the broken end of the intestine is arranged on the circular tube near each flared opening, and the hollow inner cavity of the circular tube is provided with a barrier film for blocking the hollow inner cavity. The invention used with a drainage tube realizes complete intestinal diversion without secondary operations of stoma reintroduction.
