Abstract:Objective To assess the diagnostic value of endoscopic ultrasonography-guided fine needle aspiration (EUS-FNA) for pancreatic uncinate process tumor.Methods Clinical data of 13 patients with pancreatic uncinate process tumor, who had underwent EUS-FNA, were retrospectively analyzed.Results For the 11 cases of solid neoplasm, the positive rate of histology diagnosis was 36.4% (4/11), and the positive rate of cytology diagnosis was 90.9% (10/11). Post-operative complications included one case of hyperamylasemia and one case of acute adematous pancreatitis. For the 2 cases of cystic neoplasm, cystic fluid was obtained for the analysis of cytology and tumor marker. No post-operative complications were observed.Conclusion EUS-FNA is safe and efficient for the diagnosis of pancreatic uncinate process tumor. But mastering the technical details requires experience.
