Revision Surgery is an operation done on a patient that has already had a weight loss operation. There are basically two reasons why a patient would have a revision operation:
1) To “fix” something that has gone wrong with a previous weight loss operation (complication). Examples of this might be an ulcer that won’t heal, sever reflux, nutritional issues, a big pouch, a large connection between the pouch and the small intestine, etc.
2) To change from one weight loss surgery to a different weight loss surgery. Examples of this would be removing a band and changing to a sleeve or gastric bypass, changing a vertical banded gastroplasty (“stomach stapling”) to a gastric bypass, etc.
Revision operations are very challenging and carry more risk than the usual weight loss operation. Most revision operations can still be done laparoscopically (via small incisions). Surgeon experience is very important in getting good results with revision surgery.
