目的 :观察球囊扩张治疗贲门失弛缓症的疗效及复发率 ,探讨贲门失弛缓症球囊扩张治疗后复发的预测因素。方法 :应用球囊扩张治疗并随访半年以上 ,比较复发组与非复发组在性别、年龄、病程、食管最大径、球囊扩张直径、球囊扩张类型及扩张时间等方面的差异 ,并进行多因素Logistic回归分析。结果 :球囊扩张治疗贲门失弛缓症有效率为 10 0 % ,复发率为 2 3.3% ,复发组与非复发组在年龄及病程两方面存在差异 ,病程的回归系数为 - 1.35 8(P <0 .0 5 )。结论 :球囊扩张术是治疗贲门失弛缓症有效的方法 ,但存在一定的复发率 ,病程是贲门失弛缓症球囊扩张治疗后复发的唯一预测因素。 OBJECTIVE: To observe the efficacy and recurrence rate of balloon dilatation in the treatment of achalasia and to explore the predictors of the recurrence of achalasia after balloon dilation. Methods: The patients were treated with balloon dilation and followed up for more than six months. The differences in sex, age, duration of disease, maximum esophageal diameter, diameter of balloon dilatation, type of balloon dilatation and dilation time were compared between the two groups Logistic regression analysis. Results: The effective rate of balloon dilation in the treatment of achalasia was 100% and the recurrence rate was 3.3%. There was a significant difference in the age and course between the recurrent and non-recurrent groups, with a regression coefficient of -1.358 (P < 0 .0 5). CONCLUSION: Balloon dilatation is an effective method for the treatment of achalasia, but there is a certain relapse rate. The course of disease is the only predictor of the recurrence of achalasia after balloon dilation.
