Revisions to Bariatric Surgery

Bariatric surgery typically provides a high rate of success, with most patients meeting their weight loss goals and maintaining a healthy quality of life. Sometimes, though, patients may need revisions of previous weight-loss surgery — even if those surgeries were performed the right way. 

Physicians and surgeons throughout the St. Louis area send their complex cases to us for our skill and expertise. Our program is one of only two in the entire St. Louis area that does laparoscopic revisions of bariatric surgery. We also offer nonsurgical endoscopic revisions for patients with a previous gastric bypass.

Either way, you’ll get expert treatment from physicians who have helped hundreds of people lose weight.

Laparoscopic Revision of Bariatric Surgery: How It Works

Revisions are performed by Christopher Eagon, MD, a highly skilled and experienced Washington University bariatric surgeon who has been offering weight-loss surgery at Barnes-Jewish West County Hospital since 1997. He excels at revising previous bariatric surgeries to produce the results you want.

You may need a revision of your bariatric surgery for a variety of reasons, such as:

  • Complications of the surgery itself, including:
    • Adjustable gastric band that slips
    • Gastric sleeve that leaks
    • Gastric bypass patients who develop an ulcer that doesn’t heal
  • Obesity-related medical conditions that are not resolved by initial surgery
  • Weight regain or insufficient loss

Whatever the reason for your revision, we offer laparoscopic procedures that can either:

A laparoscopic revision is a minimally invasive surgery. The surgeon uses just a few small incisions to repair or convert your previous procedure. Our laparoscopic procedure allows you to heal faster, with a lower risk of complications than open surgery.

Endoscopic Revision of Gastric Bypass Surgery: How It Works

If you have had a gastric bypass and have regained more than 20 percent of the weight you lost, you may be a candidate for an endoscopic revision. Washington University physicians at Barnes-Jewish West County Hospital have years of experience in helping people renew their weight-loss process with this nonsurgical revision. 

In the endoscopic procedure, a thin, flexible tube (endoscope) is inserted through your mouth, down your esophagus to your stomach. Using the camera on the endoscope, the physician can examine your stomach pouch and opening to the digestive tract (stoma) to see if either has enlarged.

If your pouch or stoma have enlarged, the physician uses sutures to reduce their size, helping you feel full sooner to reduce your food intake.

Bariatric Surgery Revision: What You Can Expect

If you are considering a revision to your previous bariatric surgery, your first step is a thorough medical evaluation with the Washington University physicians at Barnes-Jewish West County Hospital or Barnes-Jewish Hospital. They may need to perform tests to evaluate your stomach and digestive tract, to make sure revision surgery can help you.

You’ll then go through the same process as our new bariatric patients, including:

Nonsurgical Weight Loss Treatment Options: If you are interested in any of the nonsurgical treatment options for weight loss, you must first determine if you are a candidate and set up a personal consultation. A member of the Washington University gastroenterology team will explain the endoscopic procedures and answer your questions.
