It can be performed either endoscopically, or with formal surgery.[1] A jejunostomy may be 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.[2] A jejunostomy is different from a jejunal feeding tube which is an alternative to a gastrostomy feeding 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.[3] TechniquesThe Witzel jejunostomy is the most common method of jejunostomy creation.[4] It is an open technique where the jejunosotomy is sited 30 cm distal to the Ligament of Treitz on the antimesenteric border, with the catheter tunneled in a seromuscular groove.
