Managing a Patient with a Jejunal Tube

Placement Techniques

The American Gastroenterological Association recommends that jejunal tubes can be placed through various approaches, including direct percutaneous jejunostomy (DPEJ), percutaneous gastrostomy with jejunal extension (PEG-J), or nasojejunal (NJ) routes, with endoscopic or image-guided techniques showing success rates of 90-100% 1, 2.
Endoscopic placement techniques, such as the over-the-wire technique, have a 94% success rate, and the small-caliber endoscope technique has a success rate of over 90% 1, 3.
Image-guided jejunostomy is preferred for patients with upper GI stenosis preventing endoscope passage, though it presents challenges due to intestinal mobility 2, 4.

The American Gastroenterological Association recommends securing nasojejunal tubes properly to prevent dislodgement, which occurs in 40-80% of cases, and considering nasal bridles for high-risk patients, which can reduce accidental tube removal from 36% to 10% 5.
For percutaneous jejunostomy tubes, the external bumper should be placed approximately 1cm from the abdominal wall, and the tube should be flushed with water before and after each use to prevent clogging 5, 7.
Medications should be administered through the gastrostomy port when possible in gastrojejunostomy tubes to prevent occlusion of the smaller jejunal extension 7.

The American Gastroenterological Association recommends that if tube dislodgement occurs within 7-10 days of initial placement, replacement should be performed with endoscopic or image guidance 7.
For tube occlusion, which occurs in 3.5-35% of cases, gentle flushing with warm water should be attempted, and acidic solutions like cranberry juice or cola should be avoided 5, 7.
If occlusion persists, the tube should be replaced 7.

The American Gastroenterological Association recommends that jejunal feeding requires continuous infusion rather than bolus feeding due to the limited capacity of the jejunum, starting with isotonic formula at a low rate (10-20 mL/hr) and advancing as tolerated 6.

The American Gastroenterological Association recommends never applying suction to jejunal tubes, as this can damage jejunal mucosa, cause fluid/electrolyte imbalances, and damage the tube 6.
For patients requiring both jejunal feeding and gastric decompression, a dual-lumen tube or separate tubes for each function should be used 6.
Electrolytes should be monitored and replaced when any form of gastrointestinal suction is used 6.

The average longevity for jejunostomy tubes in gastrojejunostomy setups is 3-6 months, and regular assessment of nutritional status and adjustment of feeding regimen as needed is recommended 7.
The ongoing need for jejunal access should be evaluated, and transition to less invasive feeding methods should be considered when appropriate 6.
