Abstract: Antecedentes y objetivo: La decision de que conducta tomar ante una lesion pancreatica detectada por estudios de imagen en ocasiones no es facil. Recientemente, las biopsias obtenidas por aspiracion con aguja fina guiada por ultrasonido endoscopico (BAAF-USE) han mostrado tener un adecuado rendimiento diagnostico. El objetivo de este estudio fue evaluar el rendimiento diagnostico e impacto terapeutico de las BAAF-USE. Pacientes y metodos: 53 pacientes con lesiones pancreaticas focales fueron sometidos a BAAF-USE en el periodo de marzo/2005 a marzo/2006. El diagnostico definitivo (ideal estandar) fue realizado con base al resultado histopatologico de las muestras quirurgicas y/o el seguimiento clinico por al menos 6 meses. Resultados: 52 pacientes fueron evaluados, en 47 se obtuvieron muestras de tejido utiles para evaluacion histopatologica. La proporcion de muestras adecuadas, de acuerdo al tamano de la lesion fue: 5/6 (83.3%) en las lesiones 40 mm. Al correlacionar el resultado definitivo de las muestras obtenidas por BAAF-USE con el resultado del ideal estandar para distinguir entre lesiones benignas y malignas, la sensibilidad, especificidad, valor predictivo positivo, valor predictivo negativo y exactitud diagnostico fueron 97.3% (IC95%: 84.9-99.1), 100% (IC95%: 66-100), 100% (IC95%: 88-100), 90% (IC95%: 57-96) y 97.8%, respectivamente. En siete pacientes (14.8%) hubo un cambio en el diagnostico inicial obtenido por otros metodos de imagen. No existieron complicaciones. Conclusion: La BAAF-USE es un metodo util y seguro para la evaluacion de lesiones pancreaticas que permite una adecuada diferenciacion de lesiones benignas y malignas

Rapid On-Site Evaluation Increases Endoscopic Ultrasound-Guided Fine-Needle Aspiration Adequacy for Pancreatic Lesions
Robert L. Schmidt,Robert L. Schmidt,Benjamin L. Witt,Benjamin L. Witt,Anna P. Matynia,Anna P. Matynia,Gonzalo Barraza,Gonzalo Barraza,Lester J. Layfield,Douglas G. Adler +9 more
TL;DR: ROSE is associated with an improvement in adequacy rates when implemented at sites where the per-case adequacy rate without ROSE is low, but it is unclear whether the type of assessor (pathologist vs. non-pathologist) has a significant impact on the success rate of ROSE.

Lawrence M.J. Best,Vishal Rawji,Stephen P. Pereira,Brian R Davidson,Kurinchi Selvan Gurusamy +4 more
TL;DR: The diagnostic accuracy of various imaging modalities in detecting cancerous and precancerous lesions in people with focal pancreatic lesions was determined and the sensitivities and specificities for diagnosing cancer were determined.

Imaging Tests for the Diagnosis and Staging of Pancreatic Adenocarcinoma: A Meta-Analysis.

TL;DR: More direct evidence is needed to inform decisions about imaging tests for pancreatic adenocarcinoma, as moderate-grade evidence revealed that CT and magnetic resonance imaging had similar sensitivities and specificities for both diagnosis and vascular involvement.

TL;DR: Combining routine cytology with FISH and K-ras analyses improves diagnostic yield of EUS-FNA of solid pancreatic masses, and proposes to include these ancillary tests in the workup of atypical cytology from pancreatic EUS -FNA.

TL;DR: EUS-guided FNA is a valuable tool in the preoperative diagnostic assessment of pancreatic cystic lesions and is compared with the final histological diagnosis obtained at surgery or postmortem examination.

TL;DR: The goals of the current study were to prospectively evaluate the yield of EUS‐FNAB in the diagnosis of patients presenting with solid pancreatic lesions and to evaluate the significance of atypical, suspicious, and false‐negative aspirates.

Preliminary experience with an EUS-guided trucut biopsy needle compared with EUS-guided FNA
TL;DR: This preliminary study suggests E US-TCB can safely be used to obtain biopsy specimens of intraintestinal and extraintestinal mass lesions and lymphadenopathy and its use may reduce the number of needle passes compared with EUS-FNA.

TL;DR: EUS-FNA is a safe and highly accurate method for tissue diagnosis in suspected pancreatic cancer that allows for preoperative counseling of patients, minimizing surgeon’s operative time in cases of unresectable disease, and avoids surgical biopsies in the majority of patients with inoperable disease.
