Comparison results of perioperative indices in four groups of cases
Then we compared characteristics of perioperative periods in the four groups. Our data showed that there was no significant difference in postoperative hospital stays, number of removed lymph nodes, number of positive lymph nodes and resected length of vagina in the four groups (P > 0.05), while the differences of mean surgery time, intraoperative blood loss, postoperative exhaust time and hospital cost were statistical significance (P < 0.05), which were summarized in Table 2.
Additionally, the mean surgery time in ARH group was less than that in RRH group [(182.31 ± 55.75) vs (212.32 ± 57.13) min, P = 0.013], the VRH group was less than the ARH group, LRH group and RRH group, respectively [(139.11 ± 36.54) vs (182.31±55.75) & (184.34 ± 35.31) & (212.32 ± 57.13) min, P < 0.01]. Intraoperative blood loss in ARH group was more than that in LRH group, RRH group and VRH group, respectively [(712.50 ± 407.59) vs (224.43 ± 191.89) & (109.80 ± 92.98) & (216.67 ± 176.78) ml, P< 0.01], while RRH group was less than LRH group and the VRH group, respectively (P < 0.01 and P = 0.027). Postoperative exhaust time in LRH group was less than that in ARH group [(1.85 ± 0.70) vs (2.28±0.77) day, P = 0.013], whereas there was no significant difference among other groups (P> 0.05). Hospital cost in RRH group was more than that in ARH group, LRH group and VRH group, respectively [(6.66 ± 1.32) vs (4.54 ± 1.21) & (3.71 ± 1.41) & (3.12 ± 1.09) ×104,P < 0.01], while ARH group was more than LRH group and VRH group, respectively (P = 0.021 and P < 0.01).
