Adjustable laparoscopic gastric banding for morbid obesity: imaging assessment and complications.

Laparoscopic adjustable gastric banding (LAGB) is a safe and effective means of weight loss for patients who have morbid obesity. LAGB currently is the least invasive surgical treatment for morbid obesity. Radiologists must be aware of the expected postoperative imaging findings, the optimal technique for radiologic assessment, and the postoperative complications that may occur. In addition, because band-adjustment procedures often are performed fluoroscopically, the radiologist may play a direct role in the management of weight loss in patients following LAGB.
