The hepatoprotective effect from ischemia-reperfusion injury of remote ischemic preconditioning in the liver related surgery: a meta-analysis
Abstract
Background
This study aimed to assess the hepatoprotective effect of remote ischemic preconditioning (RIPC) in the liver related surgery.
Methods
Published articles in PubMed, Embase and Cochrane clinical trial databases were searched from the inception to May 2021. Randomized control trials (RCTs) comparing the RIPC with control or other conditionings were included for analysis. The postoperative liver synthetic function was used as the primary outcome.
Results
A total of six RCTs were included the present meta-analysis. There were 216 patients underwent RIPC and 212 patients in the control group. The RIPC group had a significantly lower level of postoperative alanine transaminase and aspartate transaminase (p<0.001). The postoperative bilirubin level was also significant lower in the RIPC group than the control group (MD = −9.0, 95%CI, −13.94 to −4.03; p<0.001). ICG clearance was reduced in controls versus RIPC (p<0.001). There was no significant difference between the RIPC and control group in terms of the complication rate.
Conclusion
The RIPC was evaluated to have a strong hepatoprotective effect from ischemia-reperfusion injury in the liver related surgery.
Conflict of interest
