The University of Alabama at Birmingham (UAB) Raptor method for direct percutaneous endoscopic gastrostomy with jejunal extension tube placement

Direct percutaneous endoscopic gastrostomy with a jejunal extension tube (PEG-J) is a useful method of providing nutrition to patients with a variety of gastrointestinal (GI) problems [1] [2]. However, placing a PEG-J is difficult, especially when delivering the jejunal extension tube into the jejunum [1] [2]. Often the J-tube bounces back into the stomach during or shortly after having positioned it endoscopically [1] [2] [3]. Indeed, some experts have developed techniques with balloon enteroscopes to block the pylorus and prevent the tube from bouncing back into the stomach [3]. The present report describes a novel and simple method of direct percutaneous endoscopic gastrostomy with PEG-J placement using an extra-long foreign body forceps.

This observational, retrospective, single-arm, open-label, institutional review board-approved case study was conducted at a tertiary care hospital during a 24-month period. It included 17 patients (9 women; mean age 56 years, range 28–79) whose diagnoses included necrotizing pancreatitis (n = 5), gastroparesis (n = 6), complex upper GI surgery (n = 3), complex fistula (n = 3), and recurrent aspiration pneumonia (n = 1).

The direct percutaneous endoscopic gastrostomy with PEG-J technique has five key steps ([Video 1]): (i) insertion of the PEG; (ii) through-the-PEG insertion of the PEG-J; (iii) use of an extra-long foreign body extraction forceps (Raptor; US Endoscopy, Ohio, USA) to advance the jejunal extension tube into the jejunum ([Fig. 1]); (iv) an exchange technique in which the scope is pulled back into the stomach while pushing on the Raptor forceps to hold the jejunal tube in place in the jejunum; and (v) once the scope is in the stomach, removal of the Raptor forceps. If during removal of the forceps, there is a slight pull or misplacement of the jejunal tube, the wide grasping prongs of the forceps can easily be used to grab the body of the tube and push it deeper into the jejunum.

Technical success using this technique was 100 %. The mean procedure time was 18 minutes (range 15–30). Clinical success was 100 % (17/17); all PEG-Js could be used for feeding purposes. There were no major adverse events. This method of inserting a PEG-J tube with an extra-long foreign body forceps was therefore safe and successful.

This report is interesting for several reasons. First, an extensive literature search did not reveal this practical method of PEG-J placement. Second, this novel method of inserting a PEG-J tube with an extra-long foreign body forceps should be easily reproducible by other endoscopists around the world. Third, we believe that this technique is a useful addition to the armamentarium of every endoscopist. Finally, the teaching video shows all of the steps to accomplish this technique. Future comparative studies are now warranted.
