CTICasesRuptured Dobhoff Feeding Tube
Imaging findings
A bedside chest radiograph demonstrates a sudden, subtle gap/separation in the radiopaque line of an indwelling enteral feeding tube. Fluoroscopy confirms complete separation and rupture of the feeding tube. The retrieved tube demonstrates localized balloon-like expansion and a longitudinal burst/rupture of the tube wall.
Key takeaways
Forceful injection of fluids using a syringe (such as a 10cc syringe) to clear an obstructed or clogged feeding tube can generate extremely high intraluminal pressure. This pressure can cause localized ballooning and catastrophic rupture/separation of the tube wall, requiring fluoroscopic snare retrieval of the distal fragment.
