作者自1981年起的10年间用气囊扩张治疗了54例近期诊断的贲门失弛缓症患者,并在治疗前后4周及以后每隔2年或症状复发时随访。随访包括:按体重减轻及吞咽困难、胸骨后疼痛、返流的频率进行评分分级;用低顺应性毛细管灌注法测定下食管括约肌(LES)静息压及LES的舒缩功能;放射学检查食管体部最大内径及食管-胃连接处最小内径;用闪烁扫描检查了13例患者食管排空率。在透视下将Browne-McHardy扩张器气囊置于食管-胃连接处,囊内充气后压力达6～
The authors treated 54 recently diagnosed patients with achalas by balloon dilatation over the 10 years from 1981 and were followed up every 2 years, 4 weeks and beyond, or when the symptoms recurred. Follow-up included: grading by weight loss and dysphagia, post-sternal pain, frequency of regurgitation; resting compliance of lower esophageal sphincter (LES) and systolic and diastolic function of lower esophageal sphincter (LES) by low compliance capillary perfusion; The maximum internal diameter of the body and the minimum internal diameter of the esophageal-gastric junction. The esophageal emptying rate of 13 patients was examined by scintigraphy. Under the perspective of the Browne-McHardy dilator balloon placed in the esophagus - stomach junction, after inflation within the capsule pressure of 6 ~
