Revision Bariatric Surgery

Revision of your Weight Loss Procedure

Revision weight loss surgery is a secondary procedure performed after previous weight loss surgery. It is an option for patients who have not achieved their desired weight loss goals, or have adverse symptoms or complications from previous weight loss operations.

Some common reasons for revision weight loss surgery include:
  • Failure to lose the desired amount of weight 
  • Regain of weight over time
  • Persistent co-morbid disease that has not resolved – for example type two diabetes
  • Severe reflux not managed with medications
Revision weight loss surgery options include:
  • Conversion from adjustable gastric band to sleeve gastrectomy (done in two operations)
  • Conversion from adjustable gastric band to a bypass
  • Conversion from sleeve gastrectomy to a bypass
  • Conversion from one type of bypass to another type of bypass
  • Revision of the original procedure – for example, adjusting the size of the stomach pouch or adjustment of bypass limb.
  • Revision due to complications – for example oversewing of a gastric leak, or repairing an internal hernia

It is important to understand that revision surgery carries with it increased risks when compared to primary procedures.  This is due to scar tissue or adhesions associated with the primary procedure, that can alter anatomy and make the process more difficult.   Patients should carefully consider their options and discuss the pros and cons with Dr Willingham. A successful revision weight loss surgery can lead to significant weight loss and improved health.
