VAZQUEZ, C. et al. Nutritional effect of bariatric surgery with Scopinaro operation: analysis of 40 cases. []. , 18, 4, pp.189-193. ISSN 1699-5198.

Objectives: 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. Design: Retrospective study from 1998-2001. Subject: 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 developped 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.
