Thoracic oesophageal diverticula are often associated with spastic motility disorders. Despite correction of the underlying motility disorder, in a subgroup of patients, symptoms persist, primarily regurgitation. Surgical diverticulectomy is then proposed; however, as the approach is thoracoscopic or via thoracotomy, it is associated with significant morbidity and cost. Descriptions of endoscopic techniques for the treatment of symptomatic midoesophageal diverticula are few. We propose the novel technique of diverticular myotomy (DM) to treat this disorder. In this case series, we describe two patients who successfully underwent DM with no adverse outcomes and excellent clinical results at 24-month follow-up.

经粘膜憩室肌切开术治疗与痉挛性运动障碍相关的食管憩室

胸食管憩室常与痉挛性运动障碍有关。尽管纠正了潜在的运动障碍，但在一部分患者中，症状仍然存在，主要是反流。然后建议手术憩室切除术；然而，由于该方法是胸腔镜或通过开胸手术，它与显着的发病率和成本相关。内镜技术用于治疗有症状的食管中憩室的描述很少。我们提出了憩室肌切开术 (DM) 的新技术来治疗这种疾病。在这个病例系列中，我们描述了两名成功接受 DM 的患者，在 24 个月的随访中没有不良后果和出色的临床结果。
