Pneumatic dilation of the lower esophageal sphincter was accomplished by endoscopic visualization and positioning of a modified polyurethane dilator (90 F diameter) without fluoroscopy in 17 consecutive patients with advanced symptomatic achalasia. All patients were monitored for completeness of dilation by pre- and postdilation radionuclide scintiscan. Despite advanced megaesophagus, prior dilatations, or complicating disease, all patients showed prompt relief of symptoms.
在17例晚期症状性贲门失弛缓症患者中，在无荧光透视的情况下，通过内镜可视化和定位改良的聚氨酯扩张器（直径90F）完成了食管下括约肌的气囊扩张。通过扩张前后的放射性核素闪烁扫描监测所有患者的扩张完整性。尽管存在晚期巨食管、既往扩张或并发疾病，但所有患者的症状均迅速缓解。
