summary . Fibrin glue (FG) is frequently used to seal and cover the anastomoses in many operations such as cardiovascular surgery or orthopaedic surgery. However, in case of gastrointestinal surgery, anastomoses are potentially contaminated, and FG may promote bacterial growth, increasing the risk of leakage. The purpose of this study was to examine the effect of cryoprecipitate‐derived FG (CryoFG) on bacterial growth. Bacterial growth on the CryoFG and on the commercial FG (Beriplast P ® ) was evaluated and compared with that on control medium. In addition, the complement activities were evaluated by heat inactivation or addition of guinea‐pig complement to the experimental settings. The CryoFG inhibited the growth of Escherichia coli , whereas the commercial FG had no effect. Heat inactivation of the CryoFG inhibited the bactericidal effect of CryoFG. Addition of guinea‐pig complement to the heat‐inactivated CryoFG could almost restore the bactericidal activity, suggesting the important role of complement. This study showed that the CryoFG preserved the complement activity, which inhibited the in vitro growth of E. coli . Therefore, we concluded that the application of the CryoFG for gastrointestinal surgical anastomoses not only would be safe but also has the advantage of reducing bacterial infection.
