A New Device for Abrasive Cytology Sampling During Upper Gastrointestinal Endoscopy: Experience in Infectious and Neoplastic Diseases

Abstract

This new device provides a fast and low-cost method of isolating pathogens and obtaining cell fragments from the gastrointestinal mucosa during routine upper gastrointestinal endoscopy.

Diagnostic findings of ultrasound‐guided fine‐needle aspiration cytology for gastrointestinal stromal tumors: Proposal of a combined cytology with newly defined features and histology diagnosis

“…Subsequent to the first report by Vilmann et al . of endoscopic ultrasonography‐guided fine‐needle aspiration (EUS‐FNA) for pancreatic tumors, 6 cytology or histology materials collected using EUS‐FNA have become widely used for diagnosis of GIST 6–12 . With this method, it has been reported that the accuracy in gastrointestinal diseases such as submucosal tumor was high (38–100%), and that complications including bleeding and infection were rare (0–2.6%), compared to conventional EUS.…”

“…For histological diagnosis, mitotic count, subclassification into spindle cell, epithelioid cell, and mixed cell, and immunohistochemistry is used for diagnosis 1,3,12,15 . Only a few reports of cytological findings, however, have been published 8,11–13 . Therefore, cytological diagnostic criteria have yet to be established for routine application.…”
