Trial Identification

Brief Title: Comparison Between Two Tissue Acquisition Techniques by Endoscopic Ultrasound. (EUS)

Official Title: Capillarity Versus Wet Technique. Comparison Between Two Methods of Tissue Acquisition Guided by Endoscopic Ultrasound.

Study ID: NCT03460197

Conditions

Digestive Cancer

Interventions

Endoscopic Ultrasound-Guided Fine-Needle Aspiration

Study Description

Brief Summary: 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.

Detailed Description: The aim of the study will be compare both techniques guided by endoscopic ultrasound (Capillarity versus Wet) and identify which obtains the best sample quality for histopathology analysis as tissue acquisition method in patients diagnosed with tumors of pancreas, biliary tract, liver or lymph nodes. The researchers are planning a prospective, pilot study in 30 subjects. All patients will be submitted to both techniques of tissue acquisition (capillarity versus wet) in the same procedure of endoscopic ultrasound. Obtained samples for histopathology analysis will be submitted to a blind examination by two different pathologists.
