23. BYPASS GASTRICO DE UNA ANASTOMOSIS (OAGB-BAGUA): RESULTADOS EN UNA SERIE DE 2850 PACIENTES DURANTE 14 AÑOS
CONCLUSIONS
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.
In conclusion

24. BYPASS GASTRICO DE UNA ANASTOMOSIS (OAGB-BAGUA): RESULTADOS EN UNA SERIE DE 2850 PACIENTES DURANTE 14 AÑOS
CONCLUSIONS
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 14-year experience.
