Application of timely regional vascular occlusion in primary liver cancer resection

Abstract

Objective To study the application effects of timely regional vascular occlusion in primary liver cancer (PLC) surgery. Methods Eighty-eight patients with PLC who underwent surgery in the Department of General Surgery of Yan′an University Affiliated Hospital from January 2014 to December 2016 were selected for prospective study, and they were divided into the experimental group and the control group by the random number table method, 44 cases of each group. In the experimental group, the blood supply was blocked with timely regional vascular occlusion while in the control group, the blood supply was blocked with half hepatic vascular occlusion. The occurrence of postoperative complications, and surgical indexes (surgical time, intraoperative blood loss, the time of hepatic portal occlusion, blood transfusion volume, abdominal drainage volume and hospital stay), levels of alanine aminotransferase, albumin and total bilirubin, levels of CD3+ , CD4+ , CD8+ and CD4+ /CD8+ , effective rate, control rate, and clinical efficacy were compared between the two groups. Measurement data with normal distribution were represented as ±s and analyzed using the independent-sample t test between the two groups; within the groups, paired t-tests were used. Comparison of count data were represented as n(%), and analyzed using the chi-square test. Results The intraoperative blood loss, time of hepatic portal occlusion, blood transfusion volume and hospital stay of the experimental group were (331.48±30.65) ml, (14.78±2.27) min, (132.61±13.87) ml, (9.29±1.19) d, and the control group were (500.61±50.62) ml, (23.96±2.89) min, (305.76±30.64) ml, (12.10±1.22) d, with statistically significant differences in above indexes between the two groups (all P 0.05). After surgery, the levels of alanine aminotransferase, total bilirubin and albumin of the experimental group were (54.86±5.61) U/L, (20.65±2.32) U/L, (41.95±4.32) ng/ml, and the control group were (120.75±13.03) U/L, (35.42±3.21) U/L, (70.25±7.45) ng/ml, with statistically significant differences in above indexes between the two groups (all P 0.05). Conclusions The application of timely regional vascular occlusion in PLC surgery can reduce the intraoperative blood loss, the time of hepatic portal occlusion, blood transfusion volume and hospital stay, improve the immune level and liver function. And there is no difference in response rate and control rate compared with half hepatic vascular occlusion, therefore it is worthy of clinical application.
