Which medical specialty performs placement of a direct percutaneous endoscopic jejunostomy (DPEJ)?

Which Specialty Performs Direct Percutaneous Endoscopic Jejunostomy (DPEJ)?

DPEJ can be performed by either gastroenterologists with advanced endoscopy training or surgeons with endoscopic expertise, with gastroenterology being the primary specialty for this procedure. 1

Primary Specialty Options

Based on multidisciplinary guidelines from the Society of Interventional Radiology and American Gastroenterological Association, DPEJ placement falls within the scope of practice of:

Gastroenterology (Primary)

• Advanced endoscopists are the most common providers of DPEJ 1
• The procedure is classified as a percutaneous endoscopic technique requiring specialized endoscopic skills
• Recent data shows gastroenterologists perform the majority of DPEJ procedures with high technical success rates (86.6-96.9%) 2

Surgery (Alternative)

• General surgeons with endoscopic training can also perform DPEJ 3
• Surgical expertise may be particularly valuable given the 5-10% risk of major complications including bowel perforation 4
• One institutional series showed both surgical and advanced endoscopists successfully performing DPEJ 3

Interventional Radiology (Less Common)

• IR can place jejunostomy tubes using fluoroscopic guidance (PIJ - percutaneous image-guided jejunostomy) 5
• However, this is technically distinct from DPEJ, which specifically requires endoscopic visualization
• IR-placed jejunostomy has higher complication rates compared to endoscopic placement 6

Practical Referral Guidance

For referral purposes, contact:

1. First choice: Gastroenterology - specifically request an advanced endoscopist or interventional endoscopist
2. Second choice: General Surgery - if they have endoscopic jejunostomy experience
3. Avoid: Standard interventional radiology - unless endoscopic placement is not feasible due to anatomy

Important Clinical Context

The guidelines emphasize that DPEJ is technically more complex than standard PEG placement 1. The procedure typically requires:

• Pediatric colonoscope for most cases 7
• Experience with the "pull" technique
• Ability to manage altered foregut anatomy (common indication) 3

Key advantage of DPEJ over alternatives: Lower tube malfunction rates (11%) compared to PEG with jejunal extension (24%), though DPEJ has higher technical complexity 2. When comparing to surgical jejunostomy, DPEJ shows 32% lower complication rates and can be performed without general anesthesia 6.

Common Pitfalls

• Don't refer to IR for "DPEJ" - they perform fluoroscopic jejunostomy (different technique with higher complication rates)
• Verify endoscopic expertise - not all gastroenterologists perform DPEJ; this requires advanced training
• Consider obesity as a risk factor - technical failure rates increase significantly in obese patients 7
