NCT03106207

Brief Summary

Despite the high success rates of gastric bypass in the short and long terms, little is known about possible anatomopathological changes that can occur in these patients. The objective is to investigate preoperative and postoperative endoscopic changes in patients undergoing gastric bypass without a ring. Thirty obese patients from different regions of the country with the surgical indication for the Roux-en-Y gastric bypass will be studied prospectively. All patients will be submitted to upper gastric endoscopy (UGE) two, six and 12 months after the surgical procedure at the Kaiser Clinic. This study will identify whether there are endoscopic changes within one year after the surgery and what they are. Changes, if they exist, will be correlated with clinical data, in order to make an accurate prognosis of the patient, thereby contributing to the outcomes of future patients submitted to this type of procedure.
