Conséquences nutritionnelles de la chirurgie digestive

Continuous improvement of digestive surgery has revealed the importance of its nutritional consequences over long term patient quality of life. These consequences, neglected for a long time, are often considered as fate or even ignored. The aim of this work is three-fold: 1) to describe nutritional consequences of surgery per se; 2) to show nutritional advantage of a more conservative surgery; 3) to remind ourselves of the digestive surgery impact over the metabolism of cobalamine, calcium and bone. The last two decades have provided less radical but equally curative surgery, while also reducing morbidity and home parenteral nutrition, vital for patients with definitive intestinal failure. This contrasts with the deficiency of nutritional care from which some patients suffer long after their surgery.
