ABSTRACT
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.

Objetivo: en el seno de la Asociación de Ecografía Digestivase decidió realizar un estudio retrospectivo multicéntrico sobre lapunción-aspiración con aguja fina (PAAF) de lesiones ocupantesde espacio pancreáticas, mediante control ecográfico y por víapercutánea, con el objetivo de valorar el rendimiento de dicha técnicay poder compararla con la punción mediante ultrasonografíaendoscópica.Participantes: en el estudio han participado 10 hospitalescon 222 pacientes con lesiones pancreáticas entre 8 y 120 mm,sospechosas de malignidad.Resultados: el análisis de los resultados muestra una sensibilidaddel 89%, especificidad 98%, valor predictivo positivo 99% ynegativo 74%, con precisión diagnóstica global 91%. No encontramosninguna complicación significativa.Conclusión: la PAAF de lesiones pancreáticas por vía percutáneaes de alta rentabilidad diagnóstica y con pocas y leves complicaciones
