ABSTRACT
Objective:
To evaluate the clinical value of CT or type-B ultrasound image-guided percutaneous core biopsy for diagnosis of pancreatic masses.Methods:
A total of 194 cases found with pancreatic lesions by type-B ultrasound, CT or magnetic resonance imaging (MRI) underwent CT or ultrasound image-guided percutaneous core biopsy. The tissue samples were examined histologically.Results:
Of 194 cases, 90 underwent CT image-guided biopsy with an average of 2.8 passes and 104 underwent type-B ultrasound image-guided biopsy with an average of 2.3 passes. The overall accuracy of diagnosis was 97.9% (190/194). There were 172 cases (90.5%) of malignant lesions, including ductal adenocarcinoma in 160 cases, cystadenocarcinoma in 4 cases, mucinous adenocarcinoma in 4 cases, malignant stromal tumor in 2 cases, and non-Hodgkin's lymphoma in 2 cases. Meanwhile, there were 18 cases (9.5%) of benign lesions, including serous cystadenoma in 4 cases, mucinous cystadenoma in 2 cases, tuberculosis in 2 cases, chronic pancreatitis in 5 cases and pancreatic pseudocyst in 5 cases. After biopsy, 20.6% (40/194) of the cases complained of abdominal pain (10 were moderate, 30 were mild) and 82.5% (160/194) of the cases had a transient elevation of serum amylase. No severe complications occured.Conclusion:
CT or type-B ultrasound image-guided percutaneous core biopsy for diagnosis of pancreatic masses is a convenient and safe method with a high positioning and diagnostic accuracy. Copyright © 2014 by TUMOR.
