Asymptomatic<unk> s seldom worsen over time, and need no treatment. Symptomatic<unk> s may be treated with esophageal dilatation, using bougie or balloon dilators. These have been found to be equally effective. Bougie dilatation involves passage of long dilating tubes of increasing size down the esophagus to stretch the area of narrowing, either over a guidewire passed into the stomach by endoscopy (the Savary-Gillard system) or using mercury-weighted dilators (the Maloney system). This is usually done with intravenous sedation to reduce discomfort. Dilatation can produce some temporary irritation. A short course of proton pump inhibitor therapy may decrease aggravation by stomach acid reflux into the esophagus. The duration of the benefit of dilation varies, but may be from months to years. Dilation may be repeated if narrowing recurs.
