Abstract:
Redundancy of the interposed colon used as an esophageal substitute is a common finding in the long-term follow-up of these patients. When symptoms caused by food retention in the colonic loop occur, surgical correction is necessary to improve quality of life and to prevent aspiration. We report a technique to straighten the redundant colon that consists of a side-to-side colocolic anastomosis using a linear stapler. This obviates the need for a redo cologastric anastomosis. Compared with resection of the loop, the operation is quick, safe, and easy to perform, and it may decrease the risk of injury to the marginal vessels of the colon graft.
