Radiological Features after Vertical Banded Gastroplasty

More than 1300 vertical banded gastroplasty operations have been performed at our hospital since November 1982. We describe the radiologic findings based on 159 of these patients, who were referred for radiologic contrast studies. Patients were referred because of abdominal pain, excess vomiting, excess weight loss, inadequate weight loss or regain of weight. The pre-contrast plain film was an important indicator of staple-line abnormalities. The radiographic findings could be divided into: abnormalities of the partition, abnormalities of the banded outlet, and ulcers and extragastric leaks.
