Comparison of operative outcomes between monopolar and bipolar coagulation in hepatectomy: a propensity score-matched analysis in a single center

Table 3 Intraoperative outcomes

	Monopolar (n = 73)	Bipolar (n = 73)	P value
Total operative time (min)	239 (74–673, 130)	275 (89–562, 115)	0.013
Transection time^a (min)	76 (15–298, 61)	90 (20–240, 67)	0.104
Pringle maneuver^b (min)	54 (15–158, 30)	66 (18–159, 35)	0.101
Blood loss (mL)	487 (0–3275, 480)	790 (145–8030, 832)	< 0.001
Red blood cell transfusion (mL)	0 (0–1120, 0)	0 (0–3360, 320)	0.002

Continuous data are presented as median (range, interquartile range). P values were calculated using the Mann–Whitney U test. Significant P values are in boldface
^aData on total transection time were partially lacking (monopolar, 58 cases; bipolar, 67 cases)
^bData on total Pringle maneuver time were partially lacking (monopolar, 46 cases; bipolar, 53 cases)
