Summary

This study compares two types of stitches used during robotic gastric bypass surgery for weight loss. About 150 adults with severe obesity will be randomly assigned to receive either a special barbed suture or a standard one. The main goal is to see which stitch is faster to use and whether it leads to fewer complications like leaks or narrowing at the connection points.
