[Evaluation of preoperative nutritional status in visceral surgery Correlational study].

Objective Is to evaluate the nutritional status of preoperative patients in the visceral surgery department III of CHU Ibn Rushd of Casablanca and to correlate to postoperative length of stay. Patients and methods Prospective observational study of six months from February 2015 to late July 2015, in patients from being operated in the visceral surgery department II1. The nutritional status of 151 patients preoperatively was evaluated the correlation between the various diagnostic tests and clinical and biological parameters was investigated and postoperative length of stay was calculated. Results 151 patients predominantly female (72.84%1, reporting their consent, were selected for this study. 51.56% of patients had risk factors for undernutrition. The cholelithiasis was the most responded diagnosis (57.61%). The Nutritional Risk Index (NRII allowed to identify 13 low nutritional risk patients, 7 moderate-risk and 3 major risk. According to the Mini Nutritional Assessment (MNA two elderly people [over 70 years] were at risk of undernutrition and one person had a bad nutritional status. Nutritional risk stratification identified 19 patients with postoperative nutritional grade 3. The average length of stay was variable; it was not correlated with the nutritional status of patients against it is based on the type of surgery. Conclusion The risk of undernutrition was high; however, a single parameter is insufficient for the diagnosis of preoperative undernutrition, a combination of different parameters would be a more reliable method.
