Revisional Surgery

Corrective surgery for a weight loss procedure

Weight loss surgery does not always result in lasting weight loss. In some instances, the first procedure undertaken by the patient may not have had the desired results. Or, may not have resulted in lasting weight loss. 

There are three main reasons why patients may seek advice on revision surgery for a first procedure. These include:

  • Regain of the original weight
  • Weight loss not significant
  • Complications following the original surgery

Types of revision surgery 

  • Removal of temporary procedure. For instance, removing existing gastric band (explanation).
  • Correction of existing procedure. For instance, further surgery for an existing gastric sleeve (re-sleeving). Or perhaps correcting a procedure performed many years ago.
  • Conversion of an existing procedure. This is commonly a gastric-band conversion to gastric bypass or gastric sleeve.

So which option is right for you?

The decision-making process around revisional surgery is determined by a great number of factors. At all times, your safety and health are our first priority. Your surgeon needs to consider:

  • age of the existing surgery
    your current anatomy and health
  • complications arisen from the original surgery
  • any existing complications

All these factors will be balanced against the efficacy of any procedure.


Bariatric surgery revision is a more difficult operation in most cases. There is additional risk around the increased time for your surgery. Conversion can be riskier due to scar tissue and other anatomical changes from your original procedure. You also may require open surgery, rather than laparoscopic (keyhole) surgery.


You may need to undergo additional testing prior to your revisional surgery. Unlike your first surgery, your range of choices may be more limited. In some cases, revision surgery may be staggered. This is often the case when removing a gastric band. In other cases, we may determine it is not safe to proceed with your correction or conversion.
