A pneumatic dilator for the treatment of achalasia of the esophagus is described. An inflatable polyurethane balloon assembly is attached to a small-caliber forward-viewing fiber-optic gastroscope. The balloon is introduced and dilatation carried out under endoscopic visual control. The described method greatly increases the safety and accuracy of the dilatation procedure, even in patients with an extreme degree of megaesophagus. 39 patients have been successfully treated with the dilator with no complications.
本文描述了一种用于治疗食管贲门失弛缓症的气动扩张器。一个可充气的聚氨酯球囊组件连接到一个小口径前视纤维光学胃镜上。球囊被插入并在内镜视觉控制下进行扩张。所描述的方法极大地提高了扩张手术的安全性和准确性，即使对于患有极度巨食管症的患者也是如此。39名患者已成功使用该扩张器进行治疗，无并发症发生。
