Abstract:
BACKGROUND:Complications with EUS-guided fine needle aspiration cytology (EUS-guided FNA) are rare and include perforation, infection, pancreatitis, and intraluminal bleeding. To date, the ultrasound appearance and clinical significance of perilesional bleeding during EUS-guided FNA have not been described. The aim of this study was to analyze the frequency of acute extraluminal hemorrhage associated with EUS-guided FNA. METHODS:From September 1998 to October 1999 EUS-guided FNA was performed during 227 of 1104 EUS procedures. Patient follow-up and complications were recorded and retrospectively analyzed. OBSERVATIONS:Three patients were identified with acute extraluminal hemorrhage at the site of the aspiration during EUS (frequency 1.3%: 95% CI [0%, 2.8%]). The bleeding manifested as an expanding echopoor region adjacent to the sampled lesion. No clinically recognizable sequela arose from the bleeding. All patients were treated with a short course of antibiotics and outpatient observation. Preprocedure coagulation and platelet assessment did not predict which patients were at risk for this complication. CONCLUSION:Acute extraluminal hemorrhage occurring during EUS-guided FNA is a rare complication with a characteristic ultrasound appearance. Recognition of this event might be important to allow the endoscopist to terminate the procedure and thereby minimize the potential for more serious bleeding.
