Brief summary
The technique of macroscopic on-site evaluation (MOSE) has recently been advocated for estimating the adequacy of a core specimen for histological diagnosis during EUS-FNA using a 19-gauge needle. How it compares to the conventional technique of tissue acquisition during EUS-FNA is uncertain. The objective of this study is to evaluate the quantity and quality of tissue, and the diagnostic ability of MOSE when compared with the conventional combined histologic-cytologic analysis.
Detailed description
To evaluate the quantity and quality of tissue, and the diagnostic ability of MOSE when compared with the conventional combined histologic-cytologic analysis in a randomized controlled study.
Interventions
Macroscopic on-site evaluation: any aspirated material on a glass slide for inspection of the presence of a macroscopic visible core (MVC). Length of MVC will be measured to determine the adequacy of that puncture.
Conventional EUS-FNA
