A jejunostomy tube, or J-tube -- also known as a percutaneous endoscopic jejunostomy tube -- is a feeding tube inserted through the abdomen and into the jejunum to provide nutrition. According to the Roswell Park Cancer Institute, J-tubes are placed if food and drink intake is inadequate; if a patient has digestion problems or difficulty emptying the stomach; or if a patient has had abdominal surgery, and surrounding organs need time to heal.
Peritonitis
A potential side effect of having a J-tube is peritonitis. This condition is an inflammation of the peritoneum, which is the lining of the abdomen. This condition may occur if the J-tube becomes dislodged or accidentally falls out. After being dislodged, the J-tube may need to be replaced with a new one, which may be more difficult and likely to cause complications. According to Roswell Park Cancer Institute, dislodged feeding tubes must be replaced within 1 to 2 hours or the hole for the tube will close. A physician must be contacted immediately if stitches become loose or the tube falls out.
Blockage Complications
Blockage of the tube may lead to inadequate feedings, which can lead to further complications such as dehydration. According to The Merck Manuals Online Medical Library, thick feedings or medications may cause a J-tube to become blocked. It may be necessary to instill a solution of pancreatic enzymes or other commercial product to help dissolve a blockage. Medications that are administered via the J-tube should be in liquid form or finely crushed and mixed with water to avoid a potential blockage.
Diarrhea, Constipation, Vomiting
Diarrhea means frequent, loose, watery stools. Loose stools may be a result of the type of formula being administered through the J-tube. Sorbitol, which is often contained in liquid drug preparations, may exacerbate diarrhea, according to the UW Health website. Constipation may occur due to inadequate fluid administration, lack of fiber in the diet or as a potential side effect of medications. Constipation may be more common in the elderly or those who are less active. Vomiting may be caused by formula intolerance, a side effect of medications or too much formula being administered at one time.
