Abstract: Objective To investigate the clinical application of frequency hematischesis cutter in liver
resection. Methods Total of 102 cases who underwent liver resection surgery in our hospital from May 2014
to May 2015 were selected and randomly divided into observation group and control group, with 51 cases
in each group. Liver resection was carried out with Habib 4X frequency hematischesis cutter in observation
group and with traditional clamp in control group. Some indexes were compared including the volume of
bleeding, obstructive time of portal vein during operation, change of liver function, volume of peritoneal
drainage after operation, disease free survival (DFS) and overall survival (OS) of patients. Results The
observation group was obviously better than the control group, which showed less bleeding amount (t =
-14.88, P ＜ 0.001), shorter operation time (t = -19.34, P ＜ 0.001), lower ratio of blood transfusion and
hepatic portal occlusion patients during operation (t = 29.99, 28.03, P ＜ 0.001). The levels of ALT and TBil
in observation group were significantly lower than those in control group on the third day after surgery (t =
-26.98, -16.38, P ＜ 0.001). The volume of peritoneal drainage at 24 h after surgery was lower and hospital
stays was shorter in observation group than those in the control group (t = -15.46，-9.33, P ＜ 0.001). There
was no significant difference between the two groups in the complications and the total cost of hospitalization
(t = 4.33, 1.38, P = 0.04, 0.17). Conclusions The application of radio frequency hemostasis and cutting
auxiliary equipment in liver resection can reduce the ratio of blood transfusion and the amount of bleeding
during operation, as well as the damage of liver function. It should contribute to improving the disease-free
survival of patients.
