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.)

Anyone interested in future collaboration in this field of research is welcome to contact our key investigator Prof. Charing CHONG in Department of Surgery, CUHK. Prof Chong’s research focuses on the field of surgical management of hepato-biliary and pancreatic diseases, especially on interventional EUS and minimally invasive hepato-biliary and pancreatic surgery.
