Use of sealants in pancreatic surgery: critical appraisal of the literature

Abstract

Background/aims: Fibrin sealants containing both fibrin and thrombin have been used to control bleeding, reinforce suture lines and enhance tissue healing. However, the literature provides contradictory results.

Methods: A systematic literature search was performed to determine the use of fibrin sealants in pancreatic surgery. These articles were then critically appraised according to their methodologies, outcomes and conclusions.

Results: Twenty-four studies were found, including 6 controlled randomized trials. Of these, 16 studies were analyzed. Many methodological flaws and lack of consistency in definitions were found, making comparisons between studies difficult if not impossible.

Conclusion: Because of the heterogeneity and lack of high-level evidence, the current literature does not allow us any conclusion: neither is there proof that fibrin sealants are of any real utility in pancreatic surgery, nor that they do not work. Further large-scale controlled trials are necessary before concluding that they do or do not provide any advantages in pancreatic surgery.
