[Nutritional effect of bariatric surgery with Scopinaro operation. Analysis of 40 cases].
OBJECTIVE
To analyze the influence of bariatric surgery over nutritional status in patients with morbid obesity after 1 year of following. To know the influence of specific factors as age, sex and common channel's length.


METHODS
Retrospective study from 1998-2001.


METHODS
All patients suffering from morbid obesity that had been operated during this period of time, 40 subjects: 28 women and 12 men with a mean age of 38 +/- 12 years old. Were studied.


METHODS
We analyzed the variations of weight and other anthropometric measures, biochemical parameters and the micronutrient (vitamins A, D, E, B12, folate, C, zinc, Calcium, Magnesium) status during 1 year of following after surgery.


RESULTS
Percentage weight loss was 29.7 +/- 2.9% without sex differences. A significant (p < 0.005) descent of serum cholesterol, triglycerides, and uric acid level as well as liver function markers was observed. All the hyperglycemic disturbances were reverted. 97% and 48% of the patients developed hypovitaminosis A and D respectively, that was correlated to steatorrhea. Vitamin E deficiency was found in 72% of the patients, and zinc deficiency in 68%


CONCLUSIONS
Our expected weight loss 1 year after bariatric surgery is 30%, irrespective of sex and age. This loss is accompanied by a significant improvement in metabolic parameters, but the high prevalence of micronutrients deficiency that was found makes an early supplementation and close follow-in of these patients very advisable.
