Abstract

TEDESCO, Amanda Kaseker et al. PRE- AND POSTOPERATIVE IN BARIATRIC SURGERY: SOME BIOCHEMICAL CHANGES. ABCD, arq. bras. cir. dig. [online]. 2016, vol.29, suppl.1, pp.67-71. ISSN 2317-6326.  https://doi.org/10.1590/0102-6720201600s10017.

Background:

The bariatric surgery may cause some nutritional deficiencies.

Aim:

To compare the serum levels of biochemical markers, in iimmediate post-surgical patients who were submitted to bariatric surgery.

Methods:

Non-concurrent prospective cross-sectional study. The analysis investigated data in medical charts of pre-surgical and immediate post-surgical patients who were submitted to bariatric surgery, focusing total cholesterol, HDL cholesterol, LDL cholesterol, triglycerides, C reactive protein, vitamin B12 levels, folic acid, homocysteine values, iron and serum calcium at the referred period.

Results:

Twenty-nine patients of both genders were evaluated. It was observed weight loss from 108.53 kg to 78.69 kg after the procedure. The variable LDL-c had a significant difference, decreasing approximately 30.3 mg/dl after the surgery. The vitamin B12 serum average levels went from 341.9 pg/ml to 667.2 pg/ml. The triglycerides values were in a range of 129.6 mg/dl-173.3 mg/dl, and 81.9 mg/dl-105.3 mg/dl at the pre- and postoperative respectively. CRP levels fall demonstrated reduction of inflammatory activity. The variable homocysteine was tested in a paired manner and it did not show a significant changing before or after, although it showed a strong correlation with LDL cholesterol.

Conclusion:

Eligible patients to bariatric surgery frequently present pre-nutritional deficiencies, having increased post-surgical risks when they don´t follow an appropriate nutritional follow-up.
