Abstract: Jejunal interposition is an alternative reconstructive method for patients with a history of gastrectomy or underwent simultaneously esophagogastrectomy.This operation generally refers to an operation in which a segment of jejunum with a pedicled blood vessel is lifted into the thoracic cavity or neck,the proximal end is anastomosed with the proximal esophagus,while the distal end maintains the continuity of the jejunum.Used in cases where the esophagus cannot be replaced by the stomach or colon.The jejunal conduit has several advantages including rich blood supply and less chance of contamination after the intestinal cavity is opened.We reviewed the literatures on the use of the jejunal interposition,and discussed the surgical methods,shortterm and longterm outcomes,as well as the quality of life.In the future,prospective investigations about jejunal interposition are required to determine the best way for digestive tract reconstruction.

Key words: jejunal interposition, conduit, esophageal cancer
