Determination of hepatic volume is an important preoperative procedure and is done
through imaging exams or standard liver volume (SLV) formulas developed based on the
biotype of each population. In the absence of a specific SLV formula for the Brazilian Eastern Amazon population, the measurement of liver volume is made with reference values
from other populations. The aim of study was to compare the hepatic volume in healthy residents from the Brazilian Eastern Amazon population obtained with magnetic resonance
imaging (MRI) and recommended SLV formulas validated to other populations. This was a
Observational, cross-sectional study. Anthropometric data of 42 healthy individuals aged
18?60 years of both sexes was collected to measure the liver volume through SLV formulas
calculations and MRI. MRI shows similarity with the Western European SLV liver volume
values and significant differences with the Japan SLV formula, mainly for women, with a
moderate-to-weak correlation with the MRI measurements. There was a strong correlation
between weight and body surface area in male patients analysed with measurements of the
liver volume by the MRI and SLV formulas. The SLV formula based on the Western European population could be used in the absence of a specific formula for individuals living in
the Amazon region. The results suggest that liver measurement formulas should take into
consideration the sex of individuals, as well as the development of a specific SLV formula
for the Eastern Amazon population and the conduction of similar studies in other Brazilian
regions. |
