内镜下气囊扩张治疗贲门失弛缓症的疗效观察

Clinical analysis of pneumatic dilation with achalasia

目的探讨内镜下气囊扩张治疗贲门失弛缓症的疗效及安全性。方法观察48例经内镜下气囊扩张治疗的贲门失弛缓症患者的临床资料,术后定期随访,观察临床症状缓解与复发情况。结果 48例患者一次性扩张成功47例,1例扩张无效转上级医院,扩张成功率为97.9%。无穿孔、大出血等严重并发症。术后随访2周～5年,16例复发,经第二次扩张均获痊愈,总有效率为97.9%。结论内镜下气囊扩张治疗贲门失弛缓症疗效佳,优点多,并发症少。

Objective To explore the efficacy and safety of endoscopic pneumatic dilation （PD） therapy for achalasia cardia （AC）. Methods A total of 48 AC sufferers were treated with PD therapy, who were later visited at regular intervals to ob- serve the situation of either the remission or the recurrence of the AC clinical symptoms. Results Of all 48 cases, the one- time PD treatments for 47 suffers were successful and thus the efficacy rate was 97.9%. Also, there was no severe compli- cations such as the perforation, the massive hemorrhage, etc. Through the following observation from 2 weeks to 5 years, it was found that 16 of the 48 patients suffered a relapse and recovered after the second-time treatment. Therefore, the gen- eral efficacy rate was 97.9%. Conclusion The endoscopic pneumatic dilation（PD） therapy is an effective, safe and economi- cal treatment for AC.
