Adjustable Gastric Band Erosion

I have had plenty of Band patients express concern for a Band Erosion after they searched the Internet for answers to some of the quirky sensations they may be having. I want to clarify what a Band Erosion is. Basically, for some reason or variety of reasons, the silicone band around the top part of your stomach erodes into the wall of the stomach. We are not always sure what causes an erosion. It could be how the surgeon did the surgery, or the patient’s eating behavior, or their particular biology. For whatever reason, know that an erosion is RARE. Only 1-2% of patients will ever experience an erosion. If it happens, patients can present in a variety of ways. However, the hallmark is a lack of restriction despite successive Band adjustments (it could also be a leak in the system!). Sometimes people can have abdominal pain, fevers, or even Port-site infections. The doctor can diagnose an erosion with an Upper GI Swallow, but the best test is an EGD. If there is indeed an erosion, then an operation is in order for Band removal.

So remember: an erosion is rare, a significant loss of restriction is the hallmark, and an EGD is the way to diagnose it.
