Sublingual Nitroglycerine Spray Facilitates Efficient Submucosal Tunneling during Per Oral Endoscopic Myotomy—A Nonrandomized Trial

Abstract

Introduction In the last one decade, per oral endoscopic myotomy (POEM) has been found to be an effective minimally invasive approach for the treatment of esophageal achalasia cardia and was lately shown to be noninferior to laparoscopic Heller's myotomy in a randomized controlled trial.
