Laparoscopic adjustable gastric banding is commonly used to treat obesity. It rarely results in complications, one of which is gastrointestinal erosion. Simultaneous erosion of the stomach and colon is a rare finding that has been documented in only a few case reports. We present a 62-year-old female with abdominal pain, nausea, and hematochezia. She was found to have simultaneous gastric and colonic erosion identified on CT scan. Imaging findings were confirmed and device was removed during surgery.
