Complications of colonic interposition.
The roentgenographic and surgical experience with 44 patients treated with colon interpositions was examined. Forty-two of these patients had carcinoma of the esophagus. Staged therapy consisted of mediastinal irradiation, colonic interposition, and total esophagectomy. The more common complications related to luminal patency and conduit integrity. A total of 29.5% developed anastomotic narrowing due to postoperative edema. Anastomotic leaks arose only at the proximal anastomosis and had an incidence rate of 31.8%. Thirty-four percent had fistulous tracts originating in the reconstructed upper gastrointestinal tract. In eighty percent of the patients with leaks or fistulae, their defects healed spontaneously or with simple drainage. Strictures were encountered in 59.1%, and there were 5 instances of colonic graft ischemia. The mortality directly related to surgery was 6.8%. Ischemia, particularly at the cervical anastomosis, is probably the most common cause of complications. Radiographic evaluation is recommended using a single contrast barium examination unless gross extravasation is expected.
