Radionuclide transit (RT) assessment of esophageal clearance was carried out in 40 patients after Heller's myotomy for achalasia and in 13 normal subjects as controls. The results showed that RT was significantly delayed irrespective to the length of postoperative period. This explained the cause of swallowing disorders in most patients after surgery. Our observation suggested that Heller's myotomy should be done as early as possible for the purpose of preventing esophageal dilation although esophageal peristalsis can not be restored by this procedure.
对40例贲门失弛缓症患者行赫勒肌切开术后进行放射性核素通过（RT）评估食管清除情况，并以13名正常受试者作为对照。结果显示，无论术后时间长短，RT均显著延迟。这解释了大多数患者术后吞咽障碍的原因。我们的观察表明，尽管该手术无法恢复食管蠕动，但为预防食管扩张，应尽早进行赫勒肌切开术。
