Table 7 Comparison of computed tomography quantitative parameters in subgroups by surgical approach, mean ± SD/median (interquartile rage)

Surgical approach	Stricture group	Non-stricture group	Statistic	P value
Total gastrectomy (n = 72)	n = 14	n = 58
nPV-HU (%)	33.8 (26.4-40.2)	50.6 (40.2-62.8)	Z = -3.512	< 0.001
PV-HU/aorta-HU	1.35 ± 0.17	1.54 ± 0.21	t = -3.124	0.002
Distal gastrectomy (n = 127)	n = 9	n = 118
nPV-HU (%)	38.2 (30.4-46.8)	53.6 (42.8-65.2)	Z =-2.687	0.007
PV-HU/aorta-HU	1.42 ± 0.19	1.57 ± 0.23	t = -2.012	0.046

aorta-HU: Abdominal aorta computed tomography value; nPV-HU: Normalized portal vein computed tomography value; PV-HU: Portal vein computed tomography value.
