Abstract:

Objective To investigate the application eff ect of hepatic lobe blood fl ow obstruction combined with selective portal vein staining in right lobe anatomical liver resection. Method The research subjects were 82 patients who underwent right lobe anatomical liver resection at Yuebei People’s Hospital from January 2022 to October 2023. They were randomly divided into two groups, an experimental group and a control group, with 41 pa-tients in each group. The experimental group received hepatic lobe blood flow obstruction, while the control group received the Pringle method of fi rst porta hepatis obstruction. Portal vein staining was performed in both groups to compare the therapeutic eff ects. Result There was no signifi cant diff erence in surgical time between the two groups of patients (P ＞ 0.05), but the experimental group had a shorter hospital stay and less intraoperative bleeding than the control group, with signifi cant diff erences (P ＜ 0.05). Before surgery, there was no signifi cant diff erence in liver function indicators between the two groups of patients (P ＞ 0.05); After surgery, the total albumin level in the experimental group was higher than that in the control group, and the total bilirubin and alanine aminotransferase levels were lower than those in the control group, with signifi cant diff erences (P ＜ 0.05). There was no signifi cant diff erence in the incidence of postoperative bile leakage, bleeding, and infection between the two groups of patients (P ＞ 0.05), but the incidence of hepatic vein injury in the experimental group was lower than that in the control group, and the recurrence rate was lower than that in the control group after 6 months of follow-up, with signifi cant diff erences (P ＜ 0.05). Conclusion The combination of hepatic lobe blood flow obstruction and portal vein stain-ing can reduce intraoperative bleeding and lower the incidence of postoperative complications in right lobe anatom-ical liver resection. It is a safe and feasible treatment method.
