To evaluate the efficacy and safety of Heller myotomy (HM) for recurrent achlasia, performed after different methods of first-line treatment.
We searched for studies published in PubMed from 1966 to March 2008 on treatment of recurrent achalasia with HM after failure with different methods of first-line treatment. The efficacy of HM was assessed by a pooled estimate of response rate with individual studies weighted proportionally to sample size.
Sixteen studies were eligible and included in the review. The results showed that HM has a better remission rate for recurrent achalasia after failure of HM [weighted mean (SD)] of 86.9% (21.8%) compared with 81.6% (23.8%) for pneumatic dilatation (PD). One study evaluated the efficacy of HM after failure of PD combined with botulinum toxin injection (83%). The most common complications were perforation and gastroesophageal reflux.
HM has the best efficacy in patients with recurrent achlasia who were treated with HM as first-line treatment. Future studies should focus on how to increase the success rate and decrease the complications of HM.
评估在采用不同一线治疗方法后进行的 heller 肌切开术(HM)治疗复发性贲门失弛缓症的疗效和安全性。
我们检索了 1966 年至 2008 年 3 月发表在 PubMed 上的关于在不同一线治疗方法失败后用 HM 治疗复发性贲门失弛缓症的研究。通过对各研究的缓解率进行汇总估计来评估 HM 的疗效,各研究按样本量加权。
16 项研究符合纳入综述的条件。结果显示,与气囊扩张术(PD)的 81.6%(标准差 23.8%)相比,HM 治疗失败后的复发性贲门失弛缓症缓解率[加权均值(标准差)]更高,为 86.9%(21.8%)。一项研究评估了在 PD 联合肉毒杆菌毒素注射失败后 HM 的疗效(83%)。最常见的并发症是穿孔和胃食管反流。
对于以 HM 作为一线治疗的复发性贲门失弛缓症患者,HM 疗效最佳。未来的研究应聚焦于如何提高 HM 的成功率并减少其并发症。
