Use of macroscopic on-site evaluation
Endoscopic ultrasound (EUS)-guided fine-needle tissue acquisition (FNTA) is a technique used to obtain tissue specimens for histological examinations. Recently, it is advocated that macroscopic on-site evaluation (MOSE) can be included in this procedure to estimate the adequacy of a specimen. In the study “Endoscopic Ultrasound-Guided Tissue Acquisition With or Without Macroscopic On-Site Evaluation: Randomized Controlled Trial”, it compared the diagnostic yield of MOSE and the conventional EUS-FNTA without rapid on-site evaluation. The result showed that the diagnostic yield was similar in two arms, but MOSE technique provided considerably fewer passes. (Endoscopy. 2020 Jun 4. doi: 10.1055/a-1172-6027. Online ahead of print.)
