【摘要】 背景:经口内镜下肌切开术(POEM)是治疗贲门失弛缓症(EA)的新技术,已有研究证实该法治疗EA可行、安全、有效,但关于术中全层肌切开与环肌切开疗效差异的报道尚少。目的:探讨POEM治疗EA的疗效和安全性。方法:2011年8月至2013年11月中南大学湘雅二医院收治EA患者216例,行POEM治疗,其中全层肌切开133例,环肌切开83例。术后对患者进行定期随访和复查,观察手术前后Eckardt评分和食管直径改变、术中、术后并发症发生情况和复发率,并比较全层肌切开与环肌切开疗效有无差异。结果:216例患者均成功实施POEM,操作时间平均为59.1 min,隧道长度平均为13.3 cm,肌切开长度平均为10.1 cm。术后患者症状均得到缓解,Eckardt评分较术前显著改善,术后6个月食管直径较术前显著缩小(53.7 mm对30.8 mm,P<0.001),并发症发生率为13.0%(28/216)。患者术后随访3~30个月(平均13.8个月),有效率为99.1%(214/216),随访期内无一例复发病例。全层肌切开与环肌切开相比,操作时间、有效率和并发症发生率差异均无统计学意义(P>0.05)。结论:POEM可作为EA安全、有效的治疗手段;全层肌切开并不增加手术操作时间和手术相关并发症,但其远期疗效和并发症仍有待进一步随访评估。更多还原

【Abstract】 Background: There have been several studies about peroral endoscopic myotomy( POEM) for treating esophageal achalasia( EA). Although the feasibility,safety and effectiveness of POEM have been demonstrated,comparative studies of full-thickness and circular muscle myotomy were rare. Aims: To evaluate the efficacy and safety of POEM for treating patients with EA. Methods: A total of 216 patients with EA admitted from Aug. 2011 to Nov. 2013 at the Second Xiangya Hospital of Central South University were treated with POEM,of whom 133 received full-thickness myotomy and 83 received circular muscle myotomy. Data about Eckardt ’s score, diameter of esophageal lumen, intra- and post-operative complications and recurrence before and /or during periodical follow-up were collected,and the efficacy of full-thickness and circular muscle myotomy was compared. Results: All the 216 patients successfully underwent POEM with an average operation time of 59. 1 minutes. Average length of tunnel and myotomy were 13. 3 cm and 10. 1 cm,respectively.Symptoms remitted in all of the 216 patients,Eckardt’s score decreased significantly,diameter of esophageal lumen was reduced( pre-treatment vs. 6 months after treatment,53. 7 mm vs. 30. 8 mm,P < 0. 001),and complications occurred in13. 0%( 28 /216) of the cases. Success treatment was achieved in 99. 1%( 214 /216) of the cases with a follow-up of 3-30 months( mean 13. 8 months),no recurrence was noted. The operation time,efficacy and complications were comparable between full-thickness and circular muscle myotomy( P > 0. 05). Conclusions: POEM is an effective and safe method for treating EA. Full-thickness myotomy did not increase the operation time and procedure-related complications,however,its long-term efficacy and complications need to be further assessed.更多还原
