The epiphrenic esophageal diverticulum is a rare non-malignant condition that is commonly associated with motility disorders. It would normally be treated surgically, but with the advancement of endoscopy techniques, peroral endoscopic myotomy with septotomy (D-POEM) has shown its benefits in coping with the symptoms. We present a case of a 71-year-old woman with increasing symptoms of dysphagia, weight loss and imaging data showing a large epiphrenic diverticulum. We treated her using peroral endoscopic myotomy combined with septotomy of the diverticular septum. The procedure showed excellent results with reducing the amount of contrast materials retained in it, improving the quality of life of the patient, and increasing her weight. There were minimal adverse events and no perforations or severe adverse effects occurred. D-POEM is a new and rapidly evolving procedure that is proving to be a safe and effective method of treating epiphrenic esophageal diverticulum.
