    What the procedure involves

    ESG is a minimally invasive transoral endoscopic procedure that reduces the volume of the stomach and may delay gastric emptying. The aim is to reduce the volume of the stomach by about 70% to 80%, reducing the amount of food that can be eaten at one time.

    The procedure is done under general anaesthesia. It may be done as a day case, but most people are kept under observation overnight and discharged the next day. A double channel scope with a procedure-specific endoscopic device attached is passed through the mouth (transorally). A series of endoluminal full-thickness suture plications (in a U, Z, square, triangle or rectangle pattern) are done along the greater curvature of the stomach (through the gastric wall, extending from the pre-pyloric antrum to the gastroesophageal junction). This involves folding the stomach in on itself and stitching it together creating a restrictive endoscopic sleeve to reduce the stomach volume by about 70% to 80%. There is no resection of the stomach and the procedure may be reversible.
