ClinConnect Summary
The YOMEGA-2 trial is studying two types of weight loss surgery: the Roux-en-Y Gastric Bypass (RYGB) and a newer method called One Anastomosis Gastric Bypass (OAGB) with a 150 cm loop. Both surgeries are designed to help people with severe obesity (a body mass index, or BMI, of 40 or higher, or 35-40 with related health issues like diabetes or high blood pressure) lose weight and improve their overall health. The goal of the trial is to see if the OAGB can provide similar weight loss results and have the same safety profile as the RYGB after two years.
To join this study, participants need to be between 18 and 65 years old, have a BMI of 35 or higher with related health issues, and agree to long-term follow-up after the surgery. They should also have undergone certain medical evaluations before being considered. Participants will receive either the OAGB or RYGB and will be monitored closely for weight loss and any nutritional issues that may arise. This trial is a great opportunity for those who want to improve their health through surgery and contribute to important research in obesity treatment.
