Figure 1.16. Small-bowel pleating and obstruction due to jejunostomy tube.

Three sections from a CT series of the abdomen and pelvis demonstrate a jejunostomy tube as it enters the abdomen (A), causes pleating of the small bowel over the tube (B), and shows an abrupt transition from dilated to normal bowel at the balloon tip of the catheter (C). The patient was clinically obstructed and improved after the tube had been removed.
