Single Anastomosis Gastro-Ileal Bypass (SAGI)

  • Chetan D. Parmar


Mini-Gastric Bypass—One Anastomosis Gastric Bypass (MGB-OAGB) is now prominent in the bariatric surgical world. Single Anastomosis Gastro Ileal (SAGI) bypass is a modification of the technique of the MGB whereby a fixed length of common channel is constructed, by performing the gastro-intestinal anastomosis 300 cm proximal to the ileocecal junction. This operation was performed on seven consecutive patients with mean BMI 42.1 kg/m2. There were no intraoperative complications. There was no mortality at 6 months follow-up. The authors concluded that SAGI may be a safer option compared to standard MGB in terms of malnutrition. However, long-term results are awaited.
