Abstract

PURPOSE
To evaluate the diagnostic yield and to assess the complications after ultrasonography-guided biopsy using an 18 G cut needle for pancreatic lesions. MATERIALS AND METHODS: Ultrasonography (Sequoia 512, Acuson, Mountain View, Ca, U.S.A.) guided biopsies using an 18 G through-cut needle (ACECUT, TSK laboratory, Tochigi-shi, Tochigi-ken, Japan) were performed on 43 patients (27 men and 16 women, mean age = 59 years) with detected pancreatic lesions. The locations of pancreatic lesions were 11 (25%) in the head and uncinate process, 2 (5%) in the neck, 15 (35%) in the body, 10 (23%) in the tail, and 5 (12%) were of the diffuse type. The diagnostic yield and assessment of complications were retrospectively analysed. RESULTS: Tissue adequate for pathologic diagnosis was obtained in 38 (88%) of 43 patients. The pancreatic lesions were confirmed as adenocarcinomas (n=26), metastasis (n=3), suspicious malignancy (n=1), inflammatory pseudotumor (n=1), microcystic cystadenoma (n=1), and chronic pancreatitis (n=6). No major complications were seen, but mild fever and transient abdominal pain did occur (n=4). CONCLUSION: Ultrasonography-guided biopsy using an 18 G cut needle is an effective and safe diagnostic method for the evaluation of pancreatic lesions.
