Which imaging method is required to verify a jejunostomy tube replacement?

• A. Ultrasound verification
• B. Radiographic verification with contrast medium
• C. Bedside visual inspection
• D. MRI confirmation

Answer: (B)

Verifying placement of a jejunostomy tube relies on radiographic imaging with contrast to visualize the tube’s path and tip. This method provides a clear, objective image showing the tube advancing from the abdominal wall into the jejunal lumen and confirms the tip is in the intended location, not coiled or mistaken for another structure. Starting feeds or medications before this confirmation can risk feeding into the stomach or outside the GI tract, with potential aspiration or other complications, so radiographic verification is required after replacement. Other options don’t reliably confirm internal position: ultrasound isn’t consistently able to visualize the tube tip in the jejunum; bedside visual inspection cannot determine internal placement; MRI isn’t practical or routinely used for this purpose and may be contraindicated.
