73-year-old man with pancreatic cancer: percutaneous gastrojejunostomy catheter placed for feeding. Contrast injection following placement of percutaneous gastrojejunostomy tube confirms that the tip of the tube is in excellent position in the jejunum (arrow). Note the gas-filled stomach (white arrow) and the locking pigtail catheter in stomach which serves to maintain catheter in position and prevent dislodgement.
