RISK OF BLEEDING COMPLICATIONS IN PERCUTANEOUS BILIARY DRAINAGE: THE PARADOX OF THE NORMAL HEMOSTASIS
ABCD: Arquivos Brasileiros de Cirurgia Digestiva
Background: Percutaneous biliary drainage is a safe procedure. The risk of bleeding complications is acceptable. Frequently, patients with biliary obstructions usually have coagulation disorders thus increasing risk of bleeding. For this reason, patients should always fit the parameters of hemostasis. Aim: To determine whether the percentage of bleeding complications in percutaneous biliary drainage is greater in adults with corrected hemostasis prior to the procedure regarding those who did
... ng those who did not require any. Methods : Prospective, observational, transversal, comparative by independent samples (unpaired comparison). Eighty-two patients with percutaneous biliary drainage were included. The average age was 64±16 years (20-92) being 38 male and 44 female. Patients who presented altered hemostasis were corrected and the presence of bleeding complications was evaluated with laboratory and ultrasound. Results: Of 82 patients, 23 needed correction of hemostasis. The approaches performed were: 41 right, 30 left and 11 bilateral. The amount of punctures on average was 3±2. There were 13 (15.8%) bleeding complications, 12 (20%) in uncorrected and only one (4.34%) in the corrected group with no statistical difference. There were no differences in side, number of punctures and type of drainage, but number of passes and the size of drainage on the right side were different. There was no related mortality. Conclusion: Bleeding complications in patients requiring hemostasis correction for a percutaneous biliary drainage was not greater than in those who did not require any.
