Inherent to surgery

Injuries to structures, bleeding, leaks

Essentially any structure near the operative site can be inadvertently injured. Injuries and bleeding are not common. For example, the risks of band surgery is around the same as gallbladder surgery.


This is more common for gastric bands and is because the band can move sometimes. The current data in Australia suggest this is around 15%, overall for bands. The reoperation rate for Sleeves and Bypass appears to be around 2 to 4%. Complications after revision surgery is 2 to 5 times higher than the initial operation.
