A randomized controlled trial of effect of 15- or 25-minute intermittent Pringle maneuver on hepatectomy for hepatocellular carcinoma.
Surgery 2022 June
BACKGROUND: The feasibility and safety of using longer ischemic interval during intermittent Pringle maneuver for hepatectomy in patients with hepatocellular carcinoma are still unclear. The aim of this study was to compare the short-term outcomes of hepatectomy using intermittent Pringle maneuver with an ischemic interval of 25 minutes versus 15 minutes in hepatocellular carcinoma patients.
METHODS: A total of 344 patients with hepatocellular carcinoma undergoing hepatectomy were randomized to receive the intermittent Pringle maneuver with a 15-minute (n = 172) or 25-minute (n = 172) ischemic interval. Primary endpoint was transaminase-based postoperative hepatic injury, assessed by their peak values as well as area under the curve of the postoperative course of aminotransferases. Secondary endpoints included the intraoperative blood loss, transection speed, morbidity, mortality, and postoperative inflammatory reaction.
RESULTS: There were no significant differences between the 2 groups in the postoperative aminotransferase serum levels or their area under the curve values, but the 25-minute intermittent Pringle maneuver group was associated with significantly higher speed for liver transection (1.38 vs 1.23 cm2 /min, P = .002) and a lower blood loss during transection (109 vs 166 mL, P < .001) than the 15-minute intermittent Pringle maneuver group. Postoperative complications, inflammatory cytokines serum levels, and 90-day mortality were comparable. Stratification analysis showed that the 25-minute intermittent Pringle maneuver did not aggravate the hepatic injury but resulted in a lower blood loss during transection and higher transection speed in hepatocellular carcinoma patient undergoing laparoscopic or open hepatectomy.
CONCLUSION: Intermittent Pringle maneuver with a 25-minute ischemic interval can be applied safely and efficiently in open or laparoscopic hepatectomy in patients with hepatocellular carcinoma patients.
