Early lateral image during gastrostomy tube injection with water soluble contrast (above right) shows the gastrostomy balloon and tip within the stomach. Later lateral image during gastrostomy tube injection (below right) shows contrast refluxing back from the stomach along the gastrostomy tube tract into the colon which is anterior to the stomach.

The diagnosis was initial malposition of the gastrostomy tube through the colon and then into the stomach.
