Abstract

Background

Hemorrhage during the liver transection is the major hazard for laparoscopic hepatectomy (LH). We aimed to evaluate the feasibility and safety of a 915-MHz microwave device used in LH.

Methods

Data were retrospectively analyzed regarding 60 patients who underwent LH with or without 915-MHz microwave coagulation at our center from January 2016 to June 2016. 30 patients underwent the 915-MHz microwave-assisted LH (MW group), and 30 patients otherwise were considered as control group.

Results

No perioperative mortality was observed. Intraoperative blood loss amounts in microwave group and control group were 26.83 ml and 186.33 ml, respectively (P < 0.001). The durations of parenchyma transaction (55.17 vs. 70.83 min, P < 0.001), blood occlusion (2.17 vs. 25.33 min, P < 0.001), and operation (120.67 vs. 148.00 min, P < 0.001) were much shorter in microwave group compared with control group. Lower incidence of postoperative complications (0.0 vs. 14.3%, P = 0.038) and shorter length of postoperative hospital stay (6.00 vs. 7.23 days, P = 0.027) were also noted in the microwave group, compared with the control group.

Conclusion

915-MHz microwave-assisted LH was found to be safe and efficient.
