Epiphrenic diverticulum are most commonly associated with which oesophageal motility disorder?
Contrast passes easily through the gastric band with no hold-up. Proximal to the gastric band there is a small diverticulum that completely empties, this is best appreciated on the oblique view. There is tertiary peristalsis in the oesophagus, which may be secondary to the gastric band. Note of contrast in the large bowel from prior CT with oral contrast.
