Abstract:
Objective To evaluate the influence of hepatic ischemia-repeffusion injury (HIRI) induced by Pringle maneuver on the prognosis of hepatoceUular carcinoma (HCC) patients after hepatectomy. Methods The chnical data of 315 HCC patients who had been admitted to Southwest Hospital from January 2004 to December 2008 were retrospectively analyzed. The 194 patients who received Pringle maneuver during hepatectomy were in the HIRI group. The control group was composed of 121 patients without portal triad clamping. The pre- and peri-operative characteristics and the prognosis of the patients were analyzed by t test, chi-square test, Kaplan-Meier survival curve, Log-rank test and Cox regression model analysis. Results Patients in the HIRI group were significantly younger than those in control group (median age, 49 vs 59) (X2 =4. 12, P < 0.05). There were 108 patients (55.7%) with large HCC (diameter > 5 cm) in the HIRI group, while the number of patients with large HCC in the control group was 83 (68.6%), with statistical difference between the 2 groups (X2=4. 12, P <0.05). The serum levels of aspartate aminotransferase on postoperative day 3 and day 7 were 255 U/L and 112 U/L, which were significantly higher than 128 U/L and 35 U/L in the control group (X2 =4.57, 5.89, P <0.05). The level of total bilirubin on postoperative day 3 was 56 U/L in the HIRI group, which was significantly higher than 39 U/L in the control group (X2=4.79, P <0.05). The disease-free survival rate and cumulative survival rate in the HIRI group were significantly lower than those in the control group (X2 = 5.93, 8. 32, P < 0. 05). Perioperative blood loss, diameter of tumor, portal triad clamping and portal vein invasion were independent factors influencing the diseasefree survival rate. Conclusions HIRI induced by Pringle maneuver significantly decreases the disease-free survival rate and cumulative survival rate of HCC patients after hepatectomy.
