Weight Loss and Quality of Life after Sleeve Gastrectomy or One-Anastomosis Gastric Bypass: Results of a Prospective Study of 120 Women with Morbid Obesity.

Our aim was to compare quality of life (QoL) after laparoscopic sleeve gastrectomy (SG) and laparoscopic one-anastomosis gastric bypass (OAGB) on obese female adult patients in the first 2 years following surgery. One hundred twenty patients with BMI over 40 kg/m2 and who underwent either SG or OAGB agreed to take part in this study. Weight loss and QoL were assessed via an online platform (e-baros®) before surgery and every 6 months after it. Two years after the operation, results showed a clinically meaningful reduction in BMI of 40.4% and a significantly meaningful improvement of QoL. No significant difference was found between the two surgical techniques for each data collection. In conclusion, both SG and OAGB techniques are effective in reducing BMI and improving QoL.
