Impact of Pringle’s maneuver on postoperative serum inflammatory mediator levels and prognosis of HBV-related HCC patients

Objective To analyze the impact of Pringle’s maneuver on postoperative serum inflammatory mediator levels and prognosis in hepatitis B virus-related hepatocellular carcinoma (HBV related HCC) patients. Methods A retrospective study was conducted on 157 HBV related HCC patients who underwent treatment at the Chinese PLA General Hospital from January 2016 to December 2017. There were 128 males and 29 females. The mean age was (54.5±12.1) years. These patients were divided into 106 patients who underwent Pringle’s maneuver (the Pringle’s maneuver group). The remaining patients were in the Occlusion-free group. All patients were detected inflammatory mediator levels including the various interleukins (IL) and were regularly followed up. The recurrence-free survival was evaluated by the Kaplan-Meier method, and compared with the log-rank test. The relationship between the Pringle’s maneuver and risks of postoperative tumor recurrence of these patient were estimated by the univariate and multivariate Cox regression models. Results On postoperation day 1 and day 3, the serum IL-1 and IL-6 levels of the Pringle’s maneuver group were significantly higher than the Occlusion-free group [5.0(5.0, 12.0)ng/L vs. 5.0(5.0, 5.0)ng/L], [122.0(74.5, 173.8)ng/L vs. 80.0(40.0, 120.0)ng/L]; [5.0(5.0, 10.0)ng/L vs. 5.0(5.0, 5.0)ng/L], [78.3(42.8, 138.5)ng/L vs. 48.1(30.1, 75.0)ng/L]. On day 5, the serum IL-1 and IL-8 levels were also significantly higher than the Occlusion-free group [5.0(5.0, 5.3)ng/L vs. 5.0(5.0, 5.0)ng/L], [100.6 (44.2, 186.5)g/L vs. 68.0(36.3, 112.0)ng/L] (all P 0.05). The multivariate Cox regression model suggested that there was no significant correlation between Pringle’s maneuver and recurrence free survival of these patients with HBV related HCC. Conclusions Pringle’s maneuver could significantly elevate the postoperative serum IL-1, IL-6, IL-8 levels, but it was not related with an increased risk of postoperative tumor recurrence.
