Standard Liver Volume in Thai Population
Abstract
Objective: To measure standard liver volume in Thai population
Patients and Methods: A total of 18-male and 2-female autopsy livers from the Department of Forensic Medicine, age ranging from 15-60 years, were investigated for this study. Liver volumes were estimated by water displacement. BSA and BMI were calculated from height and weight.
Results: The prospective data was analysed by correlation coefficient. The body weight was found to correlate with liver volume most closely (r = 0.841), while body mass index (r = 0.807), body surface area (r= 0.773) and body height (r = 0.477) correlate less closely. A linear regression formula to estimate total liver volume (TLV) based on body weight was obtained: TLV = 19.59 ± weight (kilogram; r2 = 0.988; P <.0001), A formula based on body mass index also was derived: TLV= 53.95 ± BMI (r2 = 0.987; P <.0001). A formula based on body surface area also was derived: TLV = 721.31 ± BSA (square meter; r2 = 0.981; P <.0001).
Conclusions: Total liver volume was found to correlate with body weight, body mass index (BMI) and body surface area (BSA). The formulas for the calculation of TLV were established by linear regression analysis as follow: TLV = 19.59 ± weight; TLV = 53.95 ± BMI; TLV = 721.31 ± BSA
