ABSTRACT
PURPOSE:
To introduce percutaneous selective injection of autologous platelet-rich fibrin as a novel technique for persistent bile leakage repair and sharing the results of our preliminary experience. MATERIALS ANDMETHODS:
Seven patients (57.1% females; mean age 69.6 ± 8 years) with the evidence of persistent bile leak secondary to hepatobiliary surgery and ineffective treatment with percutaneous transhepatic biliary drainage were submitted to fibrin injection. Platelet-rich fibrin, a dense fibrin clot promoting tissue regeneration, was obtained from centrifuged patient's venous blood. Repeated percutaneous injections through a catheter tip placed in close proximity to the biliary defect were performed until complete obliteration at fistulography. Technical and clinical success were evaluated.RESULTS:
Bile leaks followed pancreaticoduodenectomy in five and major hepatectomy in two patients. Technical success defined as fibrin injection at BD site was achieved in all seven patients, and clinical success defined as a complete healing of the BD at fistulography was achieved in six patients. The median time to BD closure was 76.7 ± 40.5 days and the average procedure number was 3 ± 1 per patient. In one patient, defect persistance after four treatments required gelatin sponge injection. No major complications occurred. One case of post-procedural transitory hyperpirexia was registered.CONCLUSION:
In persistent biliary defects, despite prolonged biliary drainage stay, percutaneous injection of autologous platelet-rich fibrin appears as a readily available and feasible emergent technique in promoting fistulous tracts obliteration still mantaining main ducts patency.Palavras-chave
