Abstract

Insights

The intermittent Pringle's maneuver (IPM) does not significantly reduce blood loss or transfusion needs during hepatectomy. However, it may increase risks for patients with colorectal liver metastasis (CRLM).

Area of Science:

  • Hepatobiliary surgery
  • Surgical oncology
  • Evidence-based medicine

Background:

  • The intermittent Pringle's maneuver (IPM) is a technique used during hepatectomy to control intraoperative blood loss (IBL).
  • Its clinical utility is increasingly questioned due to advancements in surgical technology and patient management.

Purpose of the Study:

  • To systematically review and meta-analyze existing studies to determine the clinical value of IPM in hepatectomy.
  • To assess the impact of IPM on intraoperative blood loss (IBL) and intraoperative blood transfusion (IBT).

Main Methods:

  • A comprehensive search of PubMed, Medline, and other databases was conducted up to October 2019.
  • Eligible studies evaluating IPM during hepatectomy were included.
  • Risk ratios (RR) with 95% confidence intervals (CI) were calculated to determine effect sizes for IBL and IBT.

Main Results:

  • The meta-analysis included 16 studies (1,770 patients in IPM group, 1,611 in non-IPM group).
  • Overall, IPM showed no significant difference in IBL or IBT compared to non-IPM.
  • For patients with colorectal liver metastasis (CRLM), IPM was associated with higher IBL and significantly higher IBT (RR=7.17, P=0.004).

Conclusions:

  • IPM has lost its clinical value for patients undergoing hepatectomy for colorectal liver metastasis (CRLM).
  • The role of IPM in hepatocellular carcinoma remains controversial.
  • No significant differences in postoperative complications were observed between IPM and non-IPM groups.
