No results posted yet for this study

Summary

This study follows patients who have undergone one-anastomosis gastric bypass (OAGB), a type of weight-loss surgery, to check for changes in the stomach and esophagus over time. All patients have an upper endoscopy before surgery and then again 1, 3, and 5 years later, even if they have no symptoms. The main goal is to see how often problems like bile reflux or ulcers at the surgical join (marginal ulcers) occur. The study also looks at whether patients' symptoms match what is seen during endoscopy.
