[Nutritional status of XXXX with digestive system @entity5 : preoperative prognostic significance].

@entity1 @entity353 @entity5 @entity69 @entity189 @entity260 @entity56 @entity1820
We have attempted to establish a prognostic nutritional index prospectively in 633 @entity1 with digestive @entity189 making it possible to predict @entity5 resectability and occurrence of @entity260 . The following factors were studied prior to surgery: age, sex, @entity353 index, triceps skinfold thickness, midarm circumference, lymphocyte count, plasma albumin, @entity69 and prealbumin levels, delayed @entity56 as investigated by 8 skin tests. The prognostic nutritional index was calculated using Mullen's formula. Unidimensional and multidimensional studies (linear discriminant and logistic discriminant analyses with partial correlations) were used for the statistical analysis. Mortality was 6,7 p. 100 while 16,2 p. 100 of @entity1 presented a @entity260 . The following variables showed a significant correlation with the resectability of the @entity5 : @entity353 (p less than 0.0001), triceps skinfold thickness (p less than 0.01), midarm circumference (p less than 0.01), total lymphocyte count (p less than 0.01), plasma @entity69 (p less than 0.01), delayed @entity56 (p less than 0.05). In the occurrence of @entity260 there was a statistically significant value only to @entity353 (p less than 0.001) and delayed @entity56 (p less than 0.05). Logistic discriminant analysis gave a linear model predicting @entity5 resectability in 78 p. 100 of @entity1 and @entity260 in 86 p. 100 of @entity1 in which @entity353 and delayed @entity56 were statistically significant. No prognostic value of Mullen's index was found. This study shows that assessment of the preoperative nutritional status of @entity1 with @entity1820 makes it possible to predict @entity5 resectability and @entity260 .
