摘要 贲门失弛缓症(achalasia,AC)是一种病因未明的食管动力障碍性疾病。主要特征是在食物进入食道时,食管下括约肌(lower esophageal sphincter,LES)出现持续性高压状态,食管体部不能形成或仅形成微弱的蠕动波,导致食物在食管腔内蓄积引起食管不断扩张,形成恶性循环,典型的临床表现包括吞咽困难、胸痛、反流、呕吐、消瘦等。对于已经确诊的AC患者,临床上的主要治疗手段包括内镜下肉毒杆菌毒素注射治疗、机械扩张治疗、手术治疗等。近年来,随着内镜器械的进步及经自然腔道内镜外科(NOTES)研究升温,经口内镜下肌切开术(Peroral Endoscopic Myotomy,POEM)治疗AC问世并逐渐应用于临床。这种方法摒弃了传统的理念,通过经口的内镜,在食管黏膜层与固有肌层之间建立一隧道,在隧道下对LES进行切开,达到治疗目的。本文就POEM治疗AC研究进展作一综述。
