Abstract

Background: Standard treatment for esophageal epiphrenic diverticula associated with achalasia includes surgical diverticulectomy, myotomy and anterior fundoplication. However, several case reports published recently suggest that endoscopic approach using per oral endoscopic myotomy is a safe and effective alternative.

Methods: This is a retrospective review of a single center case series of patients with achalasia and epiphrenic diverticula. During the treatment, the POEM guided on the opposite site of the diverticular neck without diverticulotomy was performed. Symptomatic outcome was evaluated 3 months after procedure and afterwards with the median follow-up time of 24 months. High resolution manometry was performed 3 months after the procedure.

Results: Seven patients with esophageal epiphrenic diverticula were included. POEM was successfully performed in all patients, with no complications in the periprocedural period. We observed a significant reduction of Eckardt score and the relaxation pressure of the lower esophageal sphincter (31.8 vs. 8.8 mmHg, p < .0001).

Conclusions: POEM is a promising approach in the management of achalasia and esophageal epiphrenic diverticula. We demonstrated its safety, efficiency and ability to provide symptom reduction and decrease of the LES relaxation pressure even without diverticulotomy. Multicentric studies on larger cohorts of patients and with longer follow-up time are required to confirm these results.
