This is surgery following a previous bariatric operation and it aims at either treating a complication or achieving further weight loss when a previous operation has not been quite successful or failed

• Laparoscopic removal of gastric band due to band erosion, band slippage, severe acid reflux or oesophageal (gullet) dilatation.
• Laparoscopic revision of the gastrojejunal anastomosis (the joint between the stomach and intestine) of a previous gastric bypass due to recurrent ulceration or to severe stricture (narrowing).
• Laparoscopic removal of a failed gastric band  system and conversion to gastric bypass or to sleeve gastrectomy.
• Laparoscopic conversion of sleeve gastrectomy to a gastric bypass procedure.
• Laparoscopic revisional surgery for weight regain following previous gastric bypass involving one of the following options:
  
  • Placement of a gastric band around the gastric pouch
  • Revision of the gastric pouch to reduce its size and the size of the stretched gastrojejunal anastomosis (the joint between the stomach and intestine)
  • Conversion to a “distal” gastric bypass which involves the bypass of more of the small intestine in order to induce further degree of malabsorption.
