ABSTRACT
Objective:
To investigate the application value of a new internal cold circula-tion bipolar radio frequency device in open hepatectomy.Methods:
The retrospective cohort study was conducted. The clinical data of 85 patients with hepatocellular carcinoma who underwent open hepatectomy at the Affiliated Tumor Hospital of Zhengzhou University from February 2017 to January 2020 were collected. There were 48 males and 37 females, aged from 32 to 74 years, with a median age of 52 years. Of 85 patients, 45 cases undergoing hepatectomy assisted by the new internal cold circulation bipolar radio frequency device were allocated into new internal cold circulation bipolar radio frequency device group, and 40 cases undergoing hepatectomy assisted by Habib-4X bipolar radio frequency device were allocated into Habib-4X group, respectively. Observation indicators (1) intraoperative situations; (2) postoperative situations; (3) follow-up. Follow-up was conducted by outpatient, inpatient reexamination and telephone interview to detect the postoperative complications and death of patient within postoperative 30 days up to May 2020. Measurement data with normal distribution were represented as Mean± SD, and independent sample t test was used for comparison between groups. Measurement data with skewed distribution were expressed as M(range), and nonparametric Mann-Whitney U test was used for comparison between groups. Count data were represented as absolute numbers, and comparison between groups was analyzed using the chi-square test or Fisher exact probability. Repeated measurement data were anlyzed by the repeated ANOVA.Results:
(1) Intraoperative situations the time of crosscutting process for liver parenchyma, average area transection speed, coagulation tissue width, cases with needle bleeding rate and electrode needle charring were (55±16)minutes, (4.8±1.2)cm 2/minute, (1.4±0.2)cm, 6, 10 for the new internal cold circulation bipolar radio frequency device group, versus (64±15)minutes, (3.6±1.0)cm 2/minute, (1.8±0.2)cm, 14, 25 for the Habib-4X group, respectively, showing significant differences in the above indicators between the two groups ( t=2.665, 4.973, 9.204, χ2=5.525, 14.184, P<0.05). (2) Postoperative situations for the new internal cold circulation bipolar radio frequency device group, the total bilirubin (TBil) was (20±12)μmol/L, (25±12)μmol/L, (20±14)μmol/L at postoperative 1, 3, 7 days, the prothrombin time (PT) was (15.4±2.2)seconds, (14.2±2.1)seconds, (12.7±0.8)seconds, the alanine aminotransferase (ALT) was (288±248)IU/L, (132±61)IU/L, (67±32)IU/L, the aspartate aminotransferase (AST) was (279±114)IU/L, (50±22)IU/L, (30±13)IU/L. For the Habib-4X group, the TBil was 1(22±15)μmol/L, (23±10)μmol/L, (19±8)μmol/L at postoperative 1, 3, 7 days, PT was (15.8±2.8)seconds, (14.3±2.0)seconds, (13.6±1.3)seconds, the ALT was (369±269)IU/L, (133±99)IU/L, (54±30)IU/L, the AST was (345±125)IU/L, (60±36)IU/L, (32±11)IU/L. There were significant differences in the time effect of PT, ALT, AST between the two groups ( F=18.364, 23.020, 93.786, P<0.05). There was no significant difference in the time effect, between-group effect, interaction effect of TBil or between-group effect, interaction effect of PT, ALT, AST between the two groups ( F=2.421, 1.424, 0.522, 1.593, 0.312, 0.121, 0.267, 1.027, 0.600, P>0.05). (3) Follow-up 85 patients were followed up for 4 to 39 months, with a median follow-up time of 16 months. There were 5 patients in the new internal cooling circulation bipolar radiofrequency device group and 8 patients in the Habib-4X group with complications, respectively, showing no significant difference in overall complications between the two groups ( χ2=1.292, P>0.05). The number of deaths in the new internal cooling circulation bipolar radio frequency device group and Habib-4X group was 0 and 1, respectively, showing no significant difference between the two groups ( P>0.05).Conclusion:
The new internal cold-circulating bipolar radio frequency device for open hepatectomy is safe and effective, which cuts the liver parenchyma faster, has lower carbonization rate at the tip of electrode needle, and has more accurate coagulation range.
