SYNPOSIS

Dr. Weiss outlines his initial research interest in gastric embolization of the fundus to reduce ghrelin production. He began by studying the use of sclerosants for embolization but later shifted to using embolic spheres. BAE involves the targeted embolization of the left gastric artery, with or without the left gastroepiploic artery, using 300-500 micron embolic spheres. Dr. Weiss also employs a dilute mixture of spheres and a vasodilator to achieve distal arterial penetration.

He describes the role of BAE in conjunction with existing surgical and pharmaceutical treatments. According to his experience, patients undergoing BAE achieve maximum weight loss 6-9 months after the procedure and can maintain this weight when they follow up in a weight management clinic. Additionally, Dr. Weiss reviews data from BAE studies, including the BEAT Obesity Trial and the recent BEATLES Trial.
