Abstract:
Objective To determine the value of endoscopic ultrasonography (EUS)-guided fine needle aspiration biopsy (FNAB) for differential diagnosis of pancreatic lesions. Methods EUS was performed in 23 patients with pancreatic lesions detected by CT, MRI, or US to assess the shape, size, and position of the lesions and the status of lymph nodes metastasis. After excluding blood vessel between the lesions and the fine needle by EUS, EUS guided FNAB was carried out. Results All patients were performed EUS-guided FNAB and only 2 patients failed. Among the other 21 patients, cytology and pathology demonstrated tumors in 10 patients (pancreatic carcinoma, n=8; pancreatic cystadenoma, n=1; non functional neuroendocrine tumor, n=1). The results of EUS-guided FNAB were evaluated by surgery (n=16), or clinical follow-up (n=7). The sensitivity was 83%, and speciality was 100%, and no complication occurred. Conclusions EUS-guided FNAB is a safe and accurate method for differential diagnosis of pancreatic lesions.
