The results of balloon dilatation of upper digestive tract stricture in 111 patients were evaluated. Eighty-eight patients had esophageal strictures and 23 had gastric or pyloric strictures. Thirty-six patients had strictures associated with previous operations. Twenty-two percent of the patients with esophageal strictures had malignancies. Overall, 92% were successfully dilated, with a complication rate of 3%. Follow-up information was available in 95% of patients. Eighty-seven percent of living patients experienced symptomatic improvement, which lasted for a median period of 12 mo. Forty percent required a further procedure during the period of follow-up. We found no difference between esophageal strictures and gastric or pyloric strictures in success rate, complications, or need for further dilatation, although patients with esophageal strictures were more apt to have symptomatic improvement. Postoperative strictures responded as well as nonoperative strictures. Previously dilated strictures in patients with esophageal reflux were managed as successfully as strictures never before dilated. We found balloon dilatation of upper digestive tract stricture to be a safe, effective technique.
