The relevant importance of nutritional status on the outcome of the surgical patient is well recognized. In this study two traditional markers, the percentage of weight loss (%WL) and Nutritional Risk Index (NRI), were studied in 50 patients before programmed gastroenterological surgeries, and their influence on appearance of complications were evaluate. After follow up, 40 patients with complete information were analyzed. Complications appeared in 15 patients (37.5%). %WL was <5% in 24 patients, 5–10% in 6, and >10% in 10 patients. %WL was related to usual BMI (24.6±4.1 in %WL <5%, 25.1±2.2 in %WL 5–10%, and 29.7±5.4 in %WL >10% group) and to inflammation (PCR was 1.0±1.6, 1.5±2.3 and 1.9±2.1 mg/dl in the three previous groups, respectively). Complications appeared in 33% of patients with %WL <5%, rising to 67% in those with %WL 5–10% but falling to 30% in those with %WL>10%. NRI calculated as (1.519 x Alb (g/l) + 41.7 actual/usual weight) was >100 in 26 patients (no risk), 83.5–100 in 11 (low and moderate risk), and <83.5 in 3 patients (high risk). Severity of NRI was also associated with inflammation: PCR was 0.9±1.3 in NRI >100, 1.9±2.5 in NRI 83.5–100 and 2.8±2.8 mg/dl in NRI <83.5. Complications appeared in 42%, 18% and 67% (2 of 3 cases) of the three previous groups, respectively. We conclude that severity of %WL and NRI were related to usual BMI and to inflammation, and failed to detect patients who were at risk of postoperative complications. Supported by UBACyT B090.
