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.
