Accelerated Marginal Ulcer Healing With Low-Thermal Argon Plasma Endoscopic Treatment
Christopher C. Thompson, MD, MSc
Summary
The objective of the study is to investigate the treatment of marginal ulcers with Low Thermal plasma in an endoscopic setting. By a treatment of the ulcerated areas with argon plasma with low power settings (\~ 1 W) we hypothesize that the size of the ulcers will shrink, and the healing is accelerated compared to standard of care alone. Patients will benefit from this minimally invasive approach compared to a much more invasive surgical approach that comes with higher risks and hospital stay length time. From a societal and scientific perspective, this study aims to extend the well-documented clinical benefits of plasma technology - from external wound healing to internal ulcer treatment - within an endoscopic framework. The success of this study could pave the way for broader applications of LTP in the treatment of other endoscopically accessible conditions such as peptic ulcers, duodenal ulcers and esophageal ulcers. This advancement has the potential not only to improve patient outcomes through less invasive methods, but also to position LTP as a cornerstone in the future of gastroenterological wound management strategies.
Description
Gastric bypass surgery, specifically Roux-en-Y gastric bypass (RYGB), is the second most common bariatric procedure performed worldwide (29.3%) after sleeve gastrectomy (55.4%). Despite its success in reducing obesity-related conditions, RYGB is associated with the development of marginal ulcers (MUs)-internal wounds at the gastrojejunal anastomosis prone to poor healing. The incidence of MUs in patients post-RYGB ranges widely, reported at 0.6% to 25% in the U.S., with some estimates as high as 34% worldwide due to asymptomatic cases that go undetected unless investigated endoscopically.
