"Many complications can occur following gastric banding. It is helpful to divide these into early and late post-surgical complications."
"On CT there is extra-luminal contrast, penetration of the gastric wall by the band, localised gas locules or pneumoperitoneum."

"Although the exact mode of presentation can vary depending on the underlying complication, common modes of presentation that lead to imaging evaluation include abdominal pain, retching and vomiting."
"This is seen as concentration dilation of the gastric stoma and results from stomal stenosis, adhesions or nutritional overload. Findings include a tight stoma with delayed gastric emptying. Axial herniation of the stomach, oesophageal reflux and dilation can occur as late complication."
"This is demonstrated fluoroscopically. Secondary complication from dysmotility or dilation such a gastro-oesophageal reflux, oesophagitis and aspiration may also be demonstrated. Gastro-oesophageal reflux disease (GORD), a common side effect, is seen in about 12-22% of patients with gastric banding 8."
"This can occur with either anterior or posterior upward herniation of the distal stomach upwards through the band, usually with an abnormal Phi angle. There is typically resultant eccentric (as opposed to concentric) pouch dilation."
