内镜下气囊扩张术治疗贲门失弛缓症的中远期疗效

目的：观察内镜下气囊扩张术治疗贲门失弛缓症的中远期疗效，探索贲门失弛缓症的非手术治疗方法。方法：对内镜／钡餐检查诊断为贲门失弛缓症的68例患者，用直径3．0cm,3.5cm气囊行内镜下气囊扩张治疗，疗效判断按Stooler分级法，吞咽困难减轻1级为有效，减轻2级或无醒阻为显效，以首次扩张治疗后6月－1年为中期疗效，1年以上为远期疗效，计算该疗法的中远期有效率，结果：中期疗效达100％，远期疗效为98．4％，少数复发病例再次扩张治疗后吞咽困难症状缓减，无食道大出血，穿孔等重并发症发生，结论：内镜下气囊扩张术治疗贲门失弛缓症具有良好的中远期疗效，值得推广应用。

Medium-long-term Curative Effect of Endoscopic Balloon-dilating Therapy for Achalasia

Objective:To observe the medium-long-term curative effect of endoscopic balloon-dilating therapy for achalasia.To explore a kind of non-surgical method for achalasia.Methods:68 cases with achalasia diagnosed by endoscopy/x-ray were treated with endoscopic balloon-dilating therapy,balloons of 3.0cm and 3.5cm in diameters were used,curative effect was evaluated according to Stooler method: dysphagia relieve one scale was considered good,dysphagia relieve two scales or no-dysphagia was considered excelled 6 months to 1 year after first dilation was medium-term effect,more than 1 year was long-term effect,medium-long-term effective rate was calculated.Results:Medium-term effective rate was 100%,long-term effective rate was 98.4%,a few cases with recurrent dysphagia were retreated with dilation and dysphagia was relieved.No serious complications such as massive hemorrhage and perforation of esophagus occurred.Conclusions:Endoscopic balloon-dilating therapy for achalasia had good medium-long-term curative effect and deserved for further application.
