gastrojejunostomy tube malfunction

Teenager who

is having emesis during feeding through the jejunostomy port of his gastrojejunostomy tube. AXR taken after injection through the jejunostomy port of a newly placed gastrojejunostomy tube one month ago (above) shows the tip of the jejunostomy tube to be in the proximal jejunum. AXR taken today (below) shows that the tip of the jejunostomy tube has been pulled back into the antrum of the stomach.The diagnosis was gastrojejunostomy tube malfunction due to migration of the tip of the jejunostomy tube back into the stomach.

with a gastrojejunostomy tube and chronic abdominal pain. Axial (above) CT with contrast of the abdomen shows a round soft tissue mass to the right of the vertebral body that has a target sign appearance and that has a jejunostomy tube coursing in the center of it. Coronal CT (below) shows the soft tissue mass to be long in length and to comprise the second and third parts of the duodenum and the proximal jejunum and to have the jejunostomy tube coursing throughout its length.The diagnosis was gastrojejunostomy tube malfunction due to the formation of a duodenal-jejunal intussuception forming around the tip of the jejunostomy tube.
