Patients’ perioperative clinical characteristics
The results of peri-operative blood changes between the two groups are
shown in Table 1. EBV, Hb loss, and IBL were similar in both groups. The
mean TBL of LESS-M group was 479.8±315.6 mL, which is lower than the CLM
group (490.1±361.7 mL). The VBL (p = 0.002) and post-operative drains (p
= 0.000) in the LESS-M group were less than those in the CLM group. The
mean HBL was 364.3±252.6 mL in the LESS-M group and 306.8±304.7 mL in
the CLM group. And significant differences were observed in HBL as a %
of true TBL (p=0.000) between the two groups, with a value of 74.4±22.4
% in the LESS-M group, and 58.9±30.2 % in the CLM group. However, the
PBL volumes were not significantly different (p = 0.716) between the two
groups.
