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.
良性食管梗阻几乎总是对扩张治疗有反应。因此，扩张治疗应作为初始治疗方法。Savary型扩张设备和球囊扩张系统的引入已经或即将成为标准治疗方法。在不久的将来，与埃德尔-普斯托金属橄榄头探条和充汞探条相比，这些系统将越来越受到青睐，尽管后两者仍有一些独特的适应证。目前所有可用的扩张设备都有优缺点。扩张治疗的总体症状缓解率和客观成功率是可以接受的。穿孔仍然是主要并发症。只要穿孔部位已经确定，穿孔的非手术治疗是可行的。未来需要进行对照比较研究，以确定各种扩张系统的有效性和疗效。
