Esophagoduodenostomy is a surgical procedure that involves the creation of a direct connection between the esophagus and the duodenum, which is the first part of the small intestine. This procedure is typically performed to bypass a portion of the stomach or to restore gastrointestinal continuity after the removal of the stomach, often due to conditions such as cancer or severe ulcers. By connecting these two structures, the surgery allows for the passage of food directly from the esophagus to the duodenum. It may help in managing symptoms and improving nutrition in patients with certain gastrointestinal disorders.
