详细描述
The purpose of this clinical research study is to evaluate the feasibility of the GT Metabolic Solutions Magnet System, GJ Biofragmentable ("MagGJ System") for creation of a side-to-side anastomosis for gastro-ileal or gastro-jejunal diversion in obese adults. This partial diversion of intestinal contents from the stomach to the ileum or jejunum is intended to facilitate weight management/loss in obese adults and improve metabolic outcomes in obese adults with type 2 diabetes mellitus ("T2DM"). Side-by-side anastomoses are currently created by sutures, staples, and anastomotic compression devices. A predicate procedure is the single anastomosis sleeve ileal (SASI) bypass procedure that includes a gastro-ileostomy at the distal antrum of the stomach. Additionally, the one anastomosis gastric bypass (OAGB) or single anastomosis gastric bypass (SAGB) performed in two stages may also be considered a predicate procedure where an anastomosis between the jejunum and anterior lesser curvature of the stomach is performed, followed by a second stage gastric pouch stapling more than 12 months later (non-study procedure).
