This procedure is becoming more popular. The American Society of Metabolic and Bariatric Surgeons recently endorsed this procedure. This procedure is similar to Roux en Y Gastric Bypass but involves forming only one anastomosis between the stomach and jejunum ( part of the small Bowel). This procedure induces weight loss similar to RYGB. Some studies have shown better weight loss with this procedure than RYGB. Its risk profile is identical to RYGB, except for an increased risk of Bile reflux. However, this can be dealt with easily by converting it to RYGB.
