title: The role of total parenteral nutrition in inflammatory bowel disease: current aspects.
abstract: Total parenteral nutrition (TPN) represents a therapeutic modality that could save the life of a patient with inflammatory bowel disease (IBD) facing severe nutritional problems, by restoring the patient's impaired nutritional status. TPN does not compete with enteral nutrition (EN), the latter being the first choice for all patients having anatomically intact and functionally normal digestive tract. TPN allows bowel rest while supplying adequate calorific intake and essential nutrients, and removes antigenic mucosal stimuli. The value of TPN in malnourished patients with intestinal failure due to CD is beyond doubt. However, it is difficult to suggest TPN as a sole treatment for active CD. An increased rate of remission could not be expected by applying TPN. The utility of TPN is restricted to certain cases involving efforts to close enterocutaneous or other complicated fistulas in patients with fistulizing CD, the treatment of short bowel syndrome following extensive resections for CD, or when EN is impractical for other reasons. There are no advantages of TPN therapy over EN therapy regarding fistula healing. TPN has no influence on the surgical intervention rate and little benefit by bypassing the intestinal passage could be expected. Also TPN shows no advantage if the disease is chronically active. However, an optimal supply of nutrients improves bowel motility, intestinal permeability and nutritional status, and reduces inflammatory reactions. TPN might be associated with an increased risk of adverse events, although TPN undertaken by experienced teams does not cause more complications than does EN.
