Summary
Brief summary (as posted)
There are various techniques to obtain tissue samples by using fine needle guided by endoscopic ultrasound (EUS). These techniques attempt to obtain the most adequate material with the best quantity and quality for analysis. Currently studies that compare the results concerning capillary technique versus wet technique are not available. In this sense, the authors consider necessary to explore both techniques documenting the results that can define which could be the best method so that it can routinely be used in cases of digestive neoplasia.

- measure
- The classification of Papanicolaou was used for the terminology in pancreatobiliary cytological evaluation of biopsy samples.
- timeFrame
- 4 months once the study has begun
- description
- I.- Non-diagnostic: Specimen does not provide information about whether the lesion is cystic or solid. II.- Negative (for malignancy): Specimen has adequate cellularity and / or extracellular material that defines a lesion that is identified by image. III.- Atypical: There are cells with architectural, nuclear or cytoplasmic that are not consistent with reactive changes. However, these findings are not conclusive to diagnose malignancy or suspected of malignancy. IV.- Neoplastic: benign and others. Neoplasic benign: Sample has elements of benign neoplasm. Neoplastic others: May be is a premalignant lesion like low-level dysplasia, intermediate or high grade dysplasia or a low grade neoplasm with malignant behavior. V.- Suspected of malignancy: Cytological characteristics support the Diagnosis of malignancy but quantitatively or qualitatively is not enough to confirm it. VI.- Positive / malignant: Cytological changes are unequivocal of malignancy.
