title: Liver size and serum alkaline phosphatase in normal Thai school-aged children.
abstract: The purpose of this study is to determine liver size in normal Thai school children aged 6 to 11 years, using both the clinical and ultrasonographic methods. Normal value of serum alkaline phosphatase in this age-group is also obtained. To confirm that liver function is normal, serum alanine transaminase and hepatitis B virus profile were performed. One hundred and fifty-nine normal children from Phyathai School were included in the study. They were divided into 5 age-groups: 6-7, 7-8, 8-9, 9-10 and 10-11 years. Six children were found to be asymptomatic HBsAg carriers (3.8%) and were excluded from the analysis. Mean liver sizes examined separately by two pediatricians were not significantly different, they were 8.47, 9.32, 10.06, 9.64 and 9.38 cm respectively, whereas those obtained by the ultrasonogram were 9.37, 9.17, 9.71, 10.57 and 10.21 cm respectively. Liver was palpable in 15.7 per cent of the children and liver edge did not exceed 2 cm below right costal margin. The mean value of serum alkaline phosphatase, obtained by the automate method, in these children was 223.1 unit/litre and in 97.3 per cent of them, the value did not exceed 350 unit/litre. The results of this study showed that liver size obtained clinically is comparable to size determined by ultrasonogram. Liver size in school children does not increase with age but tends to increase with body weight and height of the children.
