Interposition of the Colon


General Considerations

    • Both the stomach and colon can be used as a substitute for the esophagus
    • The indication for the procedure is usually malignancy of the esophagus; benign conditions include esophageal atresia and strictures from caustic esophagitis
    • The stomach is more frequently used than the colon today
    • When the colon is used, it is aligned so that peristalsis proceeds in the normal caudal direction
    • The left colon is usually used because of its vascular supply
    • Complications include ischemia, anastomotic leak and strictures

    The colon, outlined by swallowed barium, is seen interposed between the proximal esophagus and the stomach.
