Direct percutaneous endoscopic jejunostomy (DPEJ) is an effective method for preventing aspiration following percutaneous endoscopic gastrostomy (PEG) [1 ]. Although DPEJ provides a stable access to maintain enteral feeding, it requires an endoscope of more than 160 cm long for tube placement [2 ].
We attempted DPEJ using a transgastrostomic endoscope in post-PEG patients. A small-caliber endoscope (GIF XP-240 or GIF XP-260; Olympus Optical Co., Ltd., Tokyo, Japan) was inserted and advanced to the jejunum through the mature gastrocutaneous tract ([Fig. 1 ]). After conducting the jejunopexy with a double lumen gastropexy device (Create Medic Co., Ltd., Yokohama, Japan), a Seldinger needle was inserted through the abdomen toward an open snare using fluoroscopic guidance ([Fig. 2 ]). Next, a loop wire was inserted through the outer sheath of the Seldinger needle, grasped by the snare ([Fig. 3 ]), and pulled out with the endoscope through the gastrocutaneous tract. The loop wire was then grasped in the stomach by an orally inserted endoscope ([Fig. 4 ]) and pulled out through the mouth. Finally, a jejunostomy tube was placed in the jejunum by the pull-through technique ([Fig. 5 ]).

Fig. 2 The jejunum is fixed by a double lumen gastropexy device. A Seldinger needle then punctures the abdomen and is inserted toward an open snare.

A total of 30 DPEJ procedures were attempted in 29 patients, resulting in 28 (93.3 %) successful placements. One unsuccessful placement was due to jejunum migration away from the abdominal wall during the puncture. The other failure was due to a lack of transillumination. Maple et al. reported that the two major reasons for unsuccessful placement were lack of transillumination and the inability to pass the endoscope up to the jejunum [3 ]. The reason for the higher rate of success in the present study is that insertion of the endoscope through a gastrostomy is easy and causes little distension of the stomach. Less distension of the stomach facilitates the placement of the jejunostomy tube. DPEJ using a transgastrostomic endoscope should be recommended in cases with previous gastrostomy.
