BACKGROUND: The frequency and causes of gastrointestinal complications following esophagectomy for malignancy are unknown. PATIENTS AND METHODS: We reviewed 295 esophagectomies performed for malignancy between January 1980 and September 1994 in order to determine the frequency and causes of early and late gastrointestinal complications. RESULTS: Compared to transhiatal and left thoracoabdominal esophagectomies, esophagectomies carried out through a light posterolateral thoracotomy with cervical esophagogastric anastomosis had a higher incidence of delayed gastric emptying (11%), pneumonia (26%), and hospital death (9%), The same operation had a higher incidence of gastroesophageal reflux (20%) and dysphagia requiring esophageal dilatation (53%), We found no independent effect of gastric drainage procedures, feeding jejunostomy, preoperative radiotherapy, pathology, or age on these outcomes, Women had no operative mortality, but a higher incidence of gastroesophageal reflux and diarrhea following esophagectomy. CONCLUSIONS: Surgical techniques aimed at improving gastric emptying following esophagectomy for cancer should improve operative morbidity and mortality.
