Abstract

Background: Soft tissue sarcomas arise in the deep sites of the buttocks and lower extremities. Since a tourniquet is not applied during surgery for soft tissue sarcomas at such sites, excessive intraoperative blood loss may occur. Various devices, including LigaSure™ (Medtronic, Dublin, Ireland), are used as electrothermal bipolar vessel sealers. However, its clinical relevance in soft tissue sarcomas surgery remains unclear. This study aimed to assess the effectiveness of LigaSure™ in soft tissue sarcomas surgery. Methods: This study included 168 patients who underwent surgeries for soft tissue sarcomas in the deep sites in the buttocks and lower extremities between January 2004 and March 2018. The primary outcome was intraoperative blood loss, and secondary outcomes were surgery duration, wound complications, perioperative haemoglobin concentrations and intraoperative blood transfusion. To reduce selection biases, propensity score matching was applied. We defined the matched cases wherein LigaSure™ was used as the 'using group' and the other matched cases as the 'non-using group'. Outcomes were compared between both groups. Results: From each group, 35 cases were selected using propensity score matching. The intraoperative blood loss was significantly smaller statistically in the using group (181.5 ± 240.4 ml vs. 394.7 ± 547.3 ml, respectively; P = 0.041). The duration of operation was longer in the using group (189.9 ± 97.6 min vs. 140.6 ± 75.7 min, respectively; P = 0.007). There were no significant differences in other outcomes. Conclusion: By using LigaSure™ for soft tissue sarcomas occurring in the buttocks and lower extremities, we observed a trade-off between reduced intraoperative blood loss and longer operative time.
