Peroral Endoscopic Myotomy for the Treatment of Achalasia : An Analysis

الملخص EN

Achalasia is a motility disorder of the esophagus, characterized by aperistalsis of the esophageal body and incomplete relaxation of the lower esophageal sphincter (LES).

Treatment of achalasia is currently aimed at decreasing the resting pressure in the LES.

Peroral endoscopic myotomy (POEM) is an emerging novel endoscopic procedure for the treatment of achalasia with initial data suggesting an acceptable safety profile, excellent short-term symptom resolution, low incidence of postprocedural gastroesophageal reflux (GER), and improvement in manometric outcomes.

Further prospective randomized trials are required to evaluate the long-term effectiveness of this promising technique compared to other treatment modalities for achalasia.

In this review we outline the technical aspects of POEM, summarize the available data on safety and outcomes, and suggest future directions for further advancement of this minimally invasive approach for the treatment of achalasia.
