Underwater Pressure Lumen Expansion: A Novel Method to Overcome Lumen Collapse in Submucosal Endoscopy and Animal Endoscopic Full‐thickness Resection Models

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT In endoscopic full‐thickness resection (EFTR), luminal collapse can occur due to communication between the gastrointestinal lumen and peritoneal cavity, making visualization and procedural continuity difficult. We propose the underwater pressure lumen expansion (UPLE) method, in which hydraulic pressure is applied in a fluid‐filled environment

Who Needs Endoscopic Removal of Food Residue From the Esophagus Before Peroral Endoscopic Myotomy for Esophageal Achalasia and Esophagogastric Junction Outflow Obstruction?

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Objectives Peroral endoscopic myotomy (POEM) is an established treatment for esophageal achalasia. Despite favorable outcomes, the risk of reflux aspiration during general anesthesia induction in POEM remains a concern. This study aimed to identify the risk factors for food residue in the esophagus before POEM and evaluate the necessity of ...

Peroral Endoscopic Myotomy: Establishing a New Program [PDF]

, 2014
Achalasia is an esophageal motility disorder characterized by incomplete relaxation of the lower esophageal sphincter (LES) and aperistalsis of the esophageal body. Treatment of achalasia is aimed at decreasing the resting pressure in the LES.

Efficacy and Safety of a Revised Gastric Peroral Endoscopic Myo‐Neurotomy Procedure for Bariatric Endoscopy in a Porcine Model

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Background Endoscopic sleeve gastroplasty is a minimally invasive and effective treatment for obesity, although gastric mucosa folding and subsequent reduced visibility of the gastric lining raise concerns for some patients. This study evaluates the safety and efficacy of a revised peroral endoscopic myo‐neurotomy (R‐POEM‐N) technique using a ...
