Gastric bypass trials

Arms and Interventions. Roux-en-Y gastric bypass: Stapling and reduction of the gastric chamber of approximately 18 cm, followed by anastomosis with a deviated bowel, and another bowel anastomosis with a bowel in a lower portion, for deviation of biliopancreatic secretions. Outcome Measures. Primary Outcome Measures : Assessment of excess body weight loss [ Time Frame: 3 months after surgery ] During postoperative visits, the patient's body weight loss obtained after surgery will be assessed by means of absolute BMI values measured after the operative period and the percentage of lost BMI.

During postoperative visits, the patient's body weight loss obtained after surgery will be assessed by means of absolute BMI values measured after the operative period and the percentage of lost BMI. To assess access to the remaining stomach and duodenum, endoscopies will be performed after surgery by a professional from the endoscopy team at Hospital Geral Alberto Rassi. The questionnaire used for subjective evaluation of the surgery result and the post-operative quality of life adopted will be the BAROS Bariatric Analysis and Reporting Outcome.

The BAROS protocol consists of three major research areas weight loss, medical conditions and quality of life questionnaire , from which a maximum score of three points is obtained for each category, totaling a maximum of nine points. The questionnaire will be applied by trained researchers. Secondary Outcome Measures : Weight loss assessment through exams and interviews [ Time Frame: 18 months ] Monitoring of weight loss through weighing and questionnaire completed by the patient.
