Revision weight loss surgery

Revision weight loss surgery is a surgical procedure that is performed on patients who have already undergone a form of bariatric surgery, and have either had complications from such surgery or have not achieved significant weight loss results from the initial surgery. Procedures are usually performed laparoscopically, though open surgery may be required if prior bariatric surgery has resulted in extensive scarring.
