CTICasesRetrograde Feeding Tube Migration
Imaging findings
Lateral chest radiograph shows a feeding tube extending retrograde up the esophagus and forming a loop. Abdominal radiograph shows a percutaneous gastrostomy tube with a separate jejunostomy feeding tube extension that has disconnected from the G-tube button and migrated retrograde through the stomach and esophagus into the hypopharynx.
Key takeaways
Retrograde migration of a jejunostomy or gastrojejunostomy feeding tube is a rare iatrogenic complication. It can be triggered by vomiting or severe retching, where reverse peristalsis and stomach contraction force the loose tube upward into the esophagus. Recognizing the tube's position prevents aspiration or accidental fluid infusion into the airway, and requires endoscopic removal.
