Introduction: Three major complications occur in association with surgical liver resection: hepatocellular insufficiency, haemorrhage and biliary fistula on the hepatectomy cross-section. The liver morphology plays a role in the development of postoperative hepatocellular insufficiency, as this complication occurs when the ratio of the remaining to total liver volume is insufficient. The hepatic volume correlates with anthropometric measures. This study was performed to determine whether anthropometric characteristics influence the surface area of the hepatectomy cross-section, a liver morphological parameter related to potential complications.

Materials and Methods: We measured the parenchymal surface area of the hepatic cross-section after right hepatectomy using computed tomography, and examined correlations of this area with patients’ sex, age and anthropometric characteristics (body weight, height, Body Mass Index (BMI), Maximum Abdominal Perimeter (MAP) and body surface area).

Results: The study population comprised 140 patients (69 men and 71 women). The average surface area of the hepatectomy cross section was (73.23 ± 16.82) cm². This area correlated weakly, but significantly, with patients’ height (r=0.22, p<0.05), BMI (r=0.26, p<0.05) and MAP (r=0.23, p<0.05), and more strongly with patients’ body weight (r=0.31, p<0.001) and body surface area (r=0.31, p<0.05).

Conclusion: The surface area of the hepatectomy cross section correlates with anthropometric characteristics, with the strongest correlations observed with the body weight and body surface area.
