RESUMO
Portal vein aneurysms are rare pathologic entities. A 3.7-cm portal vein aneurysm was incidentally discovered in an 80-year-old male patient on imaging for acute abdominal pain secondary to an incarcerated diaphragmatic hernia. The aneurysm was resected, and primary repair of the portal vein was performed during a second-look operation after repair of the incarcerated hernia. Operative intervention was chosen for this patient because of the aneurysm's size and the additional indication for abdominal exploration.
RESUMO
BACKGROUND: Endoscopic ultrasound-guided fine needle biopsy (EUS-FNB) is safe and effective for the diagnosis of pancreatic adenocarcinoma. Although rapid on-site evaluation (ROSE) can improve tissue collection and increase diagnostic yield, its utility has been recently questioned. OBJECTIVE: Determine the diagnostic efficacy of EUS-FNB with ROSE of pancreatic masses in a new echoendoscopy unit. METHOD: Cross-sectional and comparative study of patients who underwent EUS-FNB of pancreatic masses between January and July 2017. Patient demographics, ultrasonographic details and pathology reports were examined. RESULTS: A total of 23 procedures were analyzed. Median age was 59 years (range: 46-77). The group with ROSE had 13 patients (56.5%) and the group without ROSE 10 (43.5%). The final pathology report showed enough and adequate sample in 100% of the group with ROSE (13/13 vs. 5/10; p = 0.007). Diagnosis of malignancy was established in 84.6% of the biopsies (11/13 vs. 2/10; p = 0.003) in the group with ROSE. CONCLUSIONS: ROSE is useful to improve the diagnostic efficacy of EUS-FNB of pancreatic masses, especially in new EUS centers or in centers with a low diagnostic yield.
ANTECEDENTES: La biopsia con aguja fina guiada por ultrasonido endoscópico (BAF-USE) es segura y eficaz para el diagnóstico del adenocarcinoma pancreático. La revisión citológica rápida en sala (ROSE, rapid on-site evaluation) puede mejorar la calidad de la muestra y el rendimiento diagnóstico; en años recientes se ha cuestionado su utilidad. OBJETIVO: Determinar la eficacia diagnóstica de la ROSE durante las BAF-USE de lesiones pancreáticas sólidas en un nuevo centro de ecoendoscopia. MÉTODO: Estudio transversal y comparativo en el que se incluyeron todos los pacientes a quienes se realizó BAF-USE de lesiones pancreáticas sólidas entre enero y julio de 2017. Se evaluaron datos demográficos, ecográficos y de patología de las BAF-USE. RESULTADOS: Se analizaron 23 procedimientos. La mediana de edad fue de 59 años (rango: 46-77). En el grupo con ROSE hubo 13 pacientes (56.5%) y en el grupo sin ROSE hubo 10 (43.5%). En el grupo con ROSE, el reporte de patología mostró muestra adecuada en el 100% (13/13 vs. 5/10; p = 0.007), así como diagnóstico de malignidad en el 84.6% (11/13 vs. 2/10; p = 0.003). CONCLUSIONES: La ROSE es una herramienta útil para mejorar el diagnóstico de BAF-USE de lesiones pancreáticas sólidas, principalmente cuando hay bajo rendimiento diagnóstico y en nuevas unidades de ecoendoscopia.
