 Possible Reasons of Failure

One of the most important reasons to seek revision weight loss surgery after failure of gastric bypass surgery is that there may have been complications in the first bariatric surgery.

Other factors can be metabolic reasons, failure to lose adequate weight & increased stomach capacity this happens when eating habits of a patient are not monitored well.

Gastric Bypass Surgery may fail for the following mechanical reasons:

  • Gastro-gastric fistula– Gastro-gastric fistula is when the stomach pocket grows back and reconnects to the bypassed stomach. This can occur as a consequence of a pocket leak, where the resulting local irritation from the leak disrupts the staple line of the bypassed stomach.
  • Pouch Dilation– It is a condition where the stomach pocket stretches out and enlarges.
  • Anastomotic Dilation– It is a condition wherein the connection between the stomach pocket and the intestine stretches out.

Weight loss surgeries are performed very often now. Therefore, there are also a large number of individuals who experience unsatisfactory results. There are several medical issues that often complicate Gastric Bypass such as stricture, marginal ulcer and severe dumping Syndrome. Revision of Gastric Bypass is necessary to treat cases of malnutrition such as vitamin issues and mineral malabsorption.

When Revision Surgery is Appropriate?

The most common reason why people consider gastric bypass revision is weight-related issues. Either you have not lost enough weight after the surgery or have gained back too much weight. Research studies show that up to 20% of patients who were morbidly obese and were suffering from obesity related health conditions . 35% of patients who were super obese have gained back more than 50% of their excess weight after 10 years. The Gastric Bypass Revision Surgery can carry risks just like your initial surgery. It is important that you will follow your surgeon’s orders exactly to avoid a second surgery.

Remove diet as the cause

  • Coordinate with your dietitian to successfully monitor what you eat using a handwritten journal.
  • Coordinate with your psychologist to determine any emotional issues to cause your diet or exercise goals fail.

Remove exercise as the cause

  • A special device known as indirect calorimeter is used to test your Basal Metabolic Rate (BMR), which is the amount of energy your body burns while resting.
  • Patients with an extremely low BMR (Basal Metabolic Rate) could have issues with weight loss even if pouch size and dietary habits are where they should be.

Gastric Bypass Revisions

Once the diet and exercise problems are ruled out, your surgeon would like to check your stomach pocket size and the gap between your stomach and your small intestines. If it happens to be too large, it can cause post-surgery weight loss problems.

Some ways of checking it are as follows:

Upper Gastrointestinal Tract Radiography

Also known as Upper GI, this process will let you drink a special colored dye, during X-Ray procedure, in order to see your digestive area “in motion”.


During this process, the surgeon will apply a numbing spray or medication; the surgeon will pass a tube with a camera through your mouth, in order to indirectly estimate the size of your pocket and stoma.

Eating Test

During this medical procedure, your surgeon will estimate your capacity of food intake before feeling full.

Types of Gastric Bypass Revision Surgery
