State-of-the-art colorectal disease: conservative surgical management of intestinal failure in adults.

HPN has drastically modified the poor prognosis of these patients, leading to an overall survival around 70-75% at 5 years in patients without cancer. However, HPN is associated with life-threatening long-term complications, including liver failure and catheter-related complications, main causes of deaths for these patients. Surgery can be proposed, in order to try to reduce SBS consequences with either conservative or non-conservative procedures. Simple bowel continuity restoration should be performed as often as possible in order to wean or at least to reduce HPN. Lengthening procedures are proposed to increase the absorption surface of the remnant bowel. These procedures can be only performed on a dilated small bowel. The slowing transit time procedure is represented by segmental reversal of the small bowel. Intestinal transplantation is the last surgical option for patients with IF but is still today associated with high mortality and failure rates. Thus, conservative procedures have a major role in the surgical armentarium for patients with IF.
