Objectives:
Sarcopenia may negatively affect short-term outcomes after liver resection. The present study aimed to explore whether total functional liver volume (TFLV) is related to sarcopenia in patients undergoing partial liver resection.
Methods:
Analysis of total liver volume and tumour volume and measurements of muscle surface were performed in patients undergoing liver resection using OsiriX(®) and preoperative computed tomography. The ratio of TFLV to bodyweight was calculated as: [TFLV (ml)/bodyweight (g)]*100%. The L3 muscle index (cm(2) /m(2) ) was then calculated by normalizing muscle areas (at the third lumbar vertebral level) for height.
Results:
Of 40 patients, 27 (67.5%) were classified as sarcopenic. There was a significant correlation between the L3 skeletal muscle index and TFLV (r= 0.64, P < 0.001). Median TFLV was significantly lower in the sarcopenia group than in the non-sarcopenia group [1396 ml (range: 1129-2625 ml) and 1840 ml (range: 867-2404 ml), respectively; P < 0.05]. Median TFLV : bodyweight ratio was significantly lower in the sarcopenia group than in the non-sarcopenia group [2.0% (range: 1.4-2.5%) and 2.3% (range: 1.5-2.5%), respectively; P < 0.05].
Conclusions:
Sarcopenic patients had a disproportionally small preoperative TFLV compared with non-sarcopenic patients undergoing liver resection. The preoperative hepatic physiologic reserve may therefore be smaller in sarcopenic patients.
