GARRE SANCHEZ, M. C. et al. Ultrasound-guided biopsy of the pancreas: A multicenter study. Rev. esp. enferm. dig. [online]. 2007, vol.99, n.9, pp.520-524. ISSN 1130-0108.

Objective: members of "Asociación de Ecografía Digestiva" decided to carry out a multicenter retrospective study on fine-needle aspiration biopsy for pancreatic space-occupying lesions under ultrasonographic guidance and via the percutaneous route in order to assess this technique's performance versus endoscopic ultrasound-guided biopsy. Subjects: 10 hospitals for a total of 222 patients with suspiciously malignant, 8-120-mm pancreatic lesions were included in the study. Results: the analysis of results shows a sensitivity of 89%, a specificity of 98%, a positive predictive value of 99%, and a negative predictive value of 74%, for an overall diagnostic accuracy of 91%. No major complications occurred. Conclusion: percutaneous fine-needle aspiration for pancreatic lesions is highly cost-effective and has few and mild complications.
