Q

Risselada, JAVMA, 2018:
Gastrojejunostomy tubes

  1. How much time should be allowed for curing to ensure no leakage?
  2. Why was the combination of a 20Fr G-tube and a 10Fr J-tube not appropriate for clinical use?
  3. What could and could not be administered through the 8Fr J-tube
A

Risselada, JAVMA, 2018:

  1. 12-24 hours for curing; constructs that were allowed to cure for only 6 hours leaked
  2. The combination of a 20Fr G-tube and a 10Fr J-tube is not appropriate for clinical use because no solution could be injected through it due to the outer diameter of the 10Fr J-tube being a similar size to the inner diameter of the 20Fr G-tube
  3. Water and enteral diet could be administered through the 8Fr J-tube but not blenderized canned diet
