Submucosal endoscopy requires transforming the submucosal layer into an endoscopic
working space to allow safe access to the muscularis propria and beyond. The submucosal
tunnel places the mucosal incision proximal to the area of interest, thereby simplifying
closure to merely mucosal apposition. The earliest clinical adaptation of submucosal
endoscopy was peroral endoscopic myotomy for the management of achalasia. More recently,
submucosal tunneling endoscopic resection has been demonstrated to be a suitable alternative
to surgical removal of tumors originating from the muscularis propria.
