Risk of bleeding during oral surgery in patients with liver cirrhosis: A systematic review.

Background: The liver is responsible for the production of almost all coagulation factors, but does this indicate a risk of developing unusual bleeding in patients with liver cirrhosis during dental surgery?

Types Of Studies Reviewed: In this systemic review, the authors followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses checklist and performed a search of PubMed, Latin American and Caribbean Health Sciences Literature, Web of Science, Scopus, and Cochrane databases.

Results: Seven studies met the inclusion criteria. The sample sizes ranged from 23 through 318 participants, number of extracted teeth ranged from 62 through 1,183, platelet count ranged from 16,000 through 216,000 per cubic milimeter, and the international normalized ratio was less than 4. The prevalence of hemorrhagic events in the studies ranged from 0% through 8.9%, and almost all were controlled with local hemostatic measures.

Conclusions And Practical Implications: During dental treatment, patients with liver cirrhosis have a low bleeding risk in spite of the decreased number of platelets and increased international normalized ratio.
