Feasibility and safety of peroral endoscopic myotomy with fundoplication in patients with achalasia: a systematic review and meta-analysis.

Background: Achalasia can cause disabling symptoms that may substantially impair the quality of life. Peroral endoscopic myotomy (POEM) has shown promising results in the management of achalasia. In this meta-analysis we have evaluated the feasibility and safety of single-session POEM with fundoplication (POEM+F) in patients with achalasia.
