Evaluation of Bariatric Endoscopic Antral Myotomy (BEAM) as a Treatment for Obesity

BEAM will be performed using a standard gastric peroral endoscopic myotomy (G-POEM) technique, however with the myotomy targeting only the antrum and leaving the pyloric ring intact. G-POEM is commonly and widely employed for gastric emptying and nutritional issues and is covered by most insurance plans. This involves injecting fluid into the submucosal space, making a mucosal incision to enter the submucosal space, and tunneling along the antrum to the pylorus. A myotomy is then performed, however, in BEAM the pyloric ring is spared and the myotomy is only performed in the antrum. The incision is then closed with clips. No endoscopic suturing will be performed.
