“…Zhang, et al [1]had evaluated 50 patients (30 LLR to 20 OLR) which indicated reduced blood loss in LLR compared to OLR (200mL vs 328mL) (P<0.05). Nassar, et al [20]also identified reduced blood loss in the LLR group compared to OLR (P≤0.001). However, one study completed by Lau, et al [21]indicated that there was no statistical difference related to blood loss (LLR 386mL, OLR 556mL, P=0.216).…”
