Severe esophageal strictures: indications for balloon catheter dilatation

Bougienage of esophageal strictures is a traditional method of therapy for patients who present with a stricture sufficiently large to permit passage of a mercury-weighted rubber bougie. However, when the residual lumen is smaller than 12 mm diameter, bougie dilatation acquires a prohibitively high risk of esophageal perforation. Twenty patients who had severe esophageal strictures have undergone surgical repair or Eder-Puestow dilatation assisted by guidewire. Fluoroscopic balloon catheter dilatation obviated surgery and allowed subsequent standard bougienage both in hospital and at home performed by the patient. We discuss indications, technique, results, and complications.
