Long-segment colon interposition for acquired esophageal disease

Background. Long-segment colon interposition has been used for esophageal r eplacement for acquired esophageal disease. The indications for use, morbid ity, and functional results of these conduits have been debated. Methods. We reviewed the medical records, office visits, and operative repo rts of patients undergoing long colon interposition for acquired esophageal disease at our institution from 1956 to 1997. Results. Long colon interposition was performed in 52 patients for caustic injury (n = 20), gastroesophageal disease (n = 16), previous irradiation (n = 8), primary motility disorders (n = 4), and acquired absence of the esop hagus (n = 4). From 1976 to 1997, acquired diseases accounted for 62% of lo ng colon interposition. The left colon was used in 46 patients and the righ t colon in 6. The in-hospital mortality rate was 4%. Early complications in cluded graft ischemia in 5 patients, anastomotic leak in 3, and small bowel obstruction in 1. Late complications included anastomotic stenosis requiri ng dilation in 26 patients, with 2 requiring surgical revision, and bile re flux requiring surgical diversion in 1 patient. Swallowing function was exc ellent in 24% of patients, good in 66%, and poor in 10%. Conclusions. Long colon interposition can be performed safely, with accepta ble long-term functional results in patients with acquired esophageal disea se. (C) 1999 by The Society of Thoracic Surgeons.
