Dilation therapy of benign esophageal stenoses.
Benign esophageal obstruction is virtually always responsive to dilation therapy. Dilation therapy should, therefore, be the initial approach. The introduction of the Savary-type dilating equipment and of balloon dilation systems are, or will become, standard practice. These systems will increasingly be preferred over the Eder-Puestow metal olives and the mercury-filled bougies in the near future, although the latter 2 will retain some distinct indications. All currently available dilating devices have advantages and shortcomings. The overall symptomatic and objective success rate of dilation therapy is acceptable. Perforation remains the major complication. Nonsurgical therapy of perforation is possible provided perforation site has occurred. Future controlled comparative studies are perforation site has occurred. Future controlled comparative studies are required to determine the usefulness and efficacy of the various dilation systems.
