Esophageal reconstruction for benign disease: early morbidity, mortality, and functional results

Background. Esophagectomy for benign disease is performed infrequently. We reviewed the Mayo Clinic’s experience with patients who required esophageal reconstruction for benign esophageal disease. Methods. From March 1956 to October 1997, all patients who required resection and reconstruction for a benign condition of the esophagus were reviewed. Results. There were 255 patients (141 male, 114 female). Median age was 55 years (range, 2 to 100). The original diagnosis was an esophageal stricture in 108 patients (42%), primary motility disorder in 84 (33%), perforation in 36 (14%), hiatal hernia in 18 (7%), and other in 9 (4.0%). Reconstruction was with stomach in 168 patients (66%), colon in 70 (27%), and small bowel in 17 (7%). The anastomosis was intrathoracic in 144 patients (57%) and cervical in 111 (43%). There were 13 postoperative deaths (mortality 5%); 142 patients (56%) had at least one complication. Median hospitalization was 14 days (range, 6–95 days). Follow-up was complete in 226 patients (88.6%) for a median of 52 months (range, 1 month to 29 years). A total of 175 patients (77.4%) were improved. Functional results were classified as excellent in 72 patients (31.8%), good in 23 (10.2%), fair in 80 (35.4%), and poor in 51 (22.6%). Conclusions. Esophageal reconstruction for benign disease resulted in functional improvement in a majority of patients. It can be done with low mortality and acceptable morbidity. Early morbidity is adversely affected by the diagnosis of perforation and the route through which the conduit is placed. Late functional outcome is adversely affected by the diagnosis of paraesophageal hernia and a cervical anastomosis.
