Imaging of pediatric gastrostomy tube malposition: Pearls and pitfalls

Figure 6 Malposition of G-port of gastrojejunostomy tube into the duodenum. A 20 year old male with increased abdominal distension and bilious output from G-port of gastrojejunostomy tube. A: Frontal radiograph shows that the G-port (black arrow) has migrated into the right upper quadrant from its ideal location in the left upper quadrant suggesting peripyloric position. The G-port should be in the left upper quadrant; B: Oblique post injection radiograph demonstrated intraluminal opacification of the duodenum (arrow) without opacification of the stomach (arrowhead) confirming a migrated G-port balloon into the pylorus or proximal duodenum.
