LAPAROSCOPIC ONE ANASTOMOSIS GASTRIC BYPASS: 13-YEAR EXPERIENCE IN 2.600 PATIENTS CONCLUSIONS 1.The OAGB (BAGUA) technique in our experience does not reduce the complexity of the surgical procedure, but significantly reduces operative time and lenght of hospital stay compared to other complex techniques; it also substantially decreases both early and late complication rates.
LAPAROSCOPIC ONE ANASTOMOSIS GASTRIC BYPASS: 13-YEAR EXPERIENCE IN 2.600 PATIENTS CONCLUSIONS 2.Excellent results in our long term follow up in regards to EWL, EBMIL, resolution of co morbidities and quality of life make OAGB a safe and effective technique, and a powerful alternative for the treatment of morbid and super morbid obesity after a 13 year experience.
