gastroenterostomy /gas′trō·en′təros″təmē/ [Gk, gaster + enteron, intestine, stoma, mouth] , surgical formation of an artificial opening between the stomach and the small intestine, usually at the jejunum. The operation is performed with a gastrectomy to route food from the remainder of the stomach into the small intestine or alone to treat a perforating ulcer of the duodenum. A GI series is done before surgery, and a nasogastric tube is inserted. The jejunum is pulled up and anastomosed with the stomach. A new opening is then made for food to pass from the stomach directly into the jejunum. Pancreatic juices and bile are still secreted into the duodenum and pass through its distal end to the jejunum. After surgery complications and care are the same as for gastrectomy. Compare gastrectomy.
