In a 7‐month‐old boy (body weight 7 kg) with congenital heart disease, short bowel syndrome, and gastric motility disorder, conventional insertion of a duodenal feeding tube was unsuccessful (Figure 1). Alternatively, a catheter‐based method under fluoroscopy was performed. An angiography catheter (4F multipurpose special; Cordis Corp., Miami Lakes, FL, USA) was inserted nasogastrically into the stomach, then a guide wire (0.014'' Whisper™ ES; Abbott Medical, Santa Clara, CA, USA) was advanced into the duodenum over which the catheter could be pushed (Figure 2A). The course of the duodenum then was visualized by manual contrast injection (Figure 2B). Next, a more stable guide wire (0.018'' Nitrex™; ev3 Inc., Plymouth, MN, USA) was carefully inserted into the distal duodenum. To enable an insertion over‐the‐wire, the closed tip of an enteral feeding tube (8 F Freka™ Tube; Fresenius Kabi AG, Bad Homburg, Germany) was cut off. To deburr it, the tip was ground down and washed. Using ultrasound gel to improve gliding ability, the tube could be easily advanced into the duodenum via the wire without any complications (Figure 2C).

Neonates and infants with severe diseases often experience nutrition difficulties. The use of naso‐gastric or, in case of gastric emptying disorders, post‐pyloric tubes may be necessary.1 Blind bedside placement of duodenal tubes can be challenging.2 Endoscopic or percutaneous approaches are alternative, but invasive techniques. Derived from conventional cardiovascular catheterization using angiography catheters under brief fluoroscopy, the over‐the‐wire technique is a simple method for the safe and correct placement of duodenal tubes.3, 4
