| pubmed-article:1483660 | pubmed:abstractText | Dilation with mercury filled bougies is the oldest and simplest technique available for treatment of benign esophageal strictures. In the majority of patients, mercury-filled dilators are effective and quite safe. Dilation is successful in 80-90%, and the rate of complication is less then 0.2%. Maloney dilators have superseded Hurst dilators because their tapered, flexible tip allows better guidance of the dilators into the lumen of the stricture. Several cautions are in order when using Maloney dilators. Dilation of difficult strictures should be observed by fluoroscopy to prevent misdirection of the dilator and esophageal perforation. Where possible, Maloney dilators should not be used to treat narrow, elongated, or angulated strictures. Dilation need not be rushed. Treatments may be repeated over months to years, both to achieve symptomatic relief initially and to maintain that state. Finally, patients susceptible to endocarditis require antibiotic prohylaxis prior to treatment. | lld:pubmed |
