Insights

Continuous Pringle maneuver (PM) reduces bleeding during liver cancer surgery without negatively affecting patient outcomes. This technique is a valuable tool for hepatic resections, including complex cases.

Area of Science:

  • Hepatobiliary surgery
  • Surgical oncology
  • Gastroenterology

Background:

  • Hepatocellular carcinoma (HCC) is a major global health concern.
  • Surgical resection is a primary treatment for HCC.
  • The Pringle maneuver (PM) is used to control bleeding during liver surgery.

Purpose of the Study:

  • To evaluate the impact of continuous Pringle maneuver (PM) on patient outcomes after hepatocellular carcinoma (HCC) resection.
  • To determine if prolonged hepatic inflow occlusion affects survival rates.

Main Methods:

  • A retrospective analysis of 586 HCC patients undergoing curative resection.
  • Comparison between patients who underwent continuous PM (n=290) and those without inflow occlusion (occlusion-free, OF group, n=296).
  • Subgroup analysis of PM group based on occlusion time (<15 min vs. 15-30 min).

Main Results:

  • The PM group had significantly less estimated blood loss than the OF group (P=0.005).
  • No significant differences in overall survival or disease-free survival (DFS) were observed between PM and OF groups.
  • Hepatic inflow occlusion time was not an independent risk factor for overall survival or DFS.

Conclusions:

  • Continuous PM is effective in reducing intraoperative bleeding during HCC resection.
  • PM does not adversely affect patient outcomes, including survival and DFS.
  • PM is a valuable tool for hepatic resection, even in complex cases requiring extended clamping times.
