description Gastroesophageal reflux disease (GERD) has been growing globally, with an increasing burden on the healthcare system due to multiple factors, such as aging and obesity. The current study evaluated the feasibility of endoscopic balloon-assisted laser treatment (EBLT) in a porcine model. GERD was initially developed in three animals via botulinum toxin injection into lower esophageal sphincter (LES). A week after the injection, the EBLT was performed on the GERD-developed models (control = 1 vs. treated = 2). A dose of 30 W of 980 nm laser light was endoscopically applied for 90 s to the LES. Both endoscopic ultrasound and manometry were performed before and after the EBLT. After 12 weeks, esophageal tissues were extracted and prepared for histological analysis. The maximum mucosa temperature was below 50 °C during the EBLT. Compared to control, the treated group yielded thicker and shorter LES muscle layers and maintained LES pressure. Through histology, the EBLT reinforced the muscularis layer with preserved mucosa and mild remodeling of the intermuscular collagen in the LES. The current study demonstrated the feasibility of EBLT as a new endoscopic approach for GERD. Further studies will examine the EBLT in a larger number of animals to warrant efficacy and safety for clinical translations
