Abstract

Background: The optimal occlusion and reperfusion time to balance blood loss and ischemia–reperfusion injury to the remnant liver remains unclear. The aim was to explore the clinical impact of prolonging the hepatic hilum occlusion time from 15 to 20 min using the intermittent Pringle maneuver (IPM) combined with controlled low central venous pressure (CLCVP).

Methods: A total of 151 patients were included and divided into an experimental group (Group 20,75 cases) and a control group (Group 15,76 cases). In both groups, the hepatic hilum was blocked by the IPM combined with CLCVP to control intraoperative hepatic cross-sectional bleeding. The preoperative, intraoperative and postoperative parameters and safety were compared between the two groups.

Results: There were no significant differences between the two groups in the postoperative aminotransferase serum levels (p > 0.05). However, the operation time in Group 20 was significantly lower than that in Group 15 (222.4 ± 87.8 vs. 250.7 ± 94.5 min, p < 0.05). The procalcitonin at 1 day after operation in Group 20 was lower than that at 1 day after operation in Group 15 (0.78 ± 0.66 vs. 1.45 ± 1.33 ng/mL, p < 0.05). There was no significant difference in the incidence of postoperative bleeding, postoperative bile leakage and postoperative infection between the two groups (p > 0.05).

Conclusions: For patients with hepatocellular carcinoma after hepatitis B cirrhosis, it is feasible and safe to prolong the hepatic hilum occlusion time from 15 to 20 min using the IPM combined with CLCVP.
