Revision surgery

Some people need additional surgery after a previous weight loss surgery, either for additional weight loss or for issues such as gastoesophageal reflux disease.

Before a revision, additional tests are usually needed. Examples of additional tests include:

  • Upper endoscopy — A camera is passed through your mouth into your esophagus and stomach. You are sedated for this procedure.
  • Upper GI series — An X-ray is taken as you swallow a special dye, called a contrast medium. The X-ray shows how the contrast medium moves through your esophagus and stomach.
  • Esophageal pH testing — This test measures how much acid refluxes from your stomach back into your esophagus. 
  • Esophageal motility testing — This test measures how well the muscles in your esophagus squeeze. 
  • Abdominal CT scanning — A computerized tomography (CT) scan combines a series of X-ray images taken of your body to create images of your internal organs.
  • Blood tests to measure vitamin levels 

You and your surgeon will discuss what options may be available to you after any needed testing is completed.
