Jejunostomy is the surgical creation of an opening (fistula) through the skin at the front of the abdomen and the wall of the jejunum (part of the small intestine). It can be performed either endoscopically, or with formal surgery.
A jejunostomy maybe formed following bowel resection in cases where there is a need for bypassing the distal small bowel and/or colon due to a bowel leak or perforation. Depending on the length of jejunum resected or bypassed the patient may have resultant short bowel syndrome and require parenteral nutrition.
A jejunostomy is different that a jejunal feeding tube which is an alternative to a gastrostomyfeeding tube commonly used when gastric enteral feeding is contraindicated or carries significant risks. The advantage over a gastrostomy is its low risk of aspiration due to its distal placement. Disadvantages include small bowel obstruction, ischemia, and requirement for continuous feeding.
