Small bowel necrosis related to enteral nutrition after duodenal surgery.

Nutritional support is the key to the successful recovery of any patient. Small bowel necrosis is described in patients being fed with enteral nutrition after surgery. Five patients with small bowel necrosis after surgery will be discussed and an etiology proposed. A retrospective review of patient data was performed. Data was collected on the type of surgical procedures performed, the enteral nutrition given to the patient, basic laboratory data, the length of stay, and discharge status. A total of five patients' charts were reviewed. Three patients had pancreaticoduodenectomy for a pancreatic mass and two required pyloric exclusion secondary to gunshot wounds. All five patients were fed with a fiber-based enteral nutrition. All patients subsequently had small bowel necrosis requiring reoperation. Four of the five patients had inspissated tube feeding within the necrotic small bowel. Two patients died and three survived with prolonged hospital courses. We propose that the combination of duodenal surgery and fiber-based enteral nutrition contribute to the development of small bowel necrosis postoperatively.
