Revision Bariatric Surgery

What is Revision Bariatric Surgery?

Revision bariatric (weight loss) surgery refers to a second surgery that is performed to modify or correct a previous bariatric procedure. It is typically considered for patients who have not achieved the desired weight loss results, have regained weight, or are experiencing complications or adverse effects from the initial surgery.

Within Australia and our practice, we are seeing a rise in rate of revision surgery. This is attributed to the maturity of bariatric surgery within Australia and in particular larger cities like Sydney, where the number of patients who have undergone primary weight loss surgery is increasing.

Common Reasons for Considering Revisional Surgery

The decision to undergo revision surgery can be difficult to make on your own. At SGOS, we have had decades of experience and can work with you on whether undergoing revision surgery is beneficial to you.

What Revision Surgery Options Do You Have?

This does depend on your primary weight loss surgery

Here are the most common revision options:

  • Removal of Gastric Band and converting to Gastric Sleeve
  • Removal of Gastric Band and converting to Gastric Bypass

For more information on band revision, please read: https://pubmed.ncbi.nlm.nih.gov/28569358/

  • If the volume of your sleeve is on the larger side – There may be an option to consider Re-sleeve
  • Conversion of Gastric Sleeve to Gastric Bypass
  • If you suffer from significant reflux and have concurrent hiatal hernia – Repair of Hiatal Hernia or conversion to Gastric Bypass
  • If you are experiencing issues with sleeve stricture – endoscopic dilitation options to correct points of excessive narrowing

For more information on re-sleeve and its utility – please read: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10720822/

  • If you are suffering from bile reflux symptoms – we can consider converting Mini Bypass (one anastomosis gastric bypass) to Roux – en Y Gastric Bypass
  • Lengthening your Bypass to achieve better weight loss control
  • Endoscopic options with Overstitich Device to narrow the existing Gastric pouch or reducing the gastric outlet to improve restriction

What are the Risks and Outcomes?


  • Revision surgeries are generally more complex and carry higher risks than the initial procedures due to scar tissue, altered anatomy, and previous surgical changes.


  • Revision bariatric surgery can be effective in achieving additional weight loss and resolving complications, but outcomes can vary widely based on the patient’s health, the type of revision performed, and adherence to post-operative guidelines.
