Gastric operation for the morbidly obese.

The surgical approach to the morbidly obese patient has been changing over the years because of complications of the procedure. Evolution of gastric surgical techniques has resulted in a decrease in the radiologically evident complications such as anastomotic leaks, abscess, and marginal ulceration. Knowledge of the pertinent surgical and radiographic anatomy is important to the radiologist in evaluating the patient who has undergone a gastric bypass or gastroplasty for morbid obesity.
