Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

In most Asian medical centers, rapid on-site cytology evaluation is not available, the number of needle passes of EUS-FNA is decided by endoscopists. Full-field optical coherence tomography (FF-OCT) is a new optical imaging technique that could generate sectioning tomogram from fresh tissue and provide close-to-pathology depiction of the morphological structure and pathological changes in minutes without conventional tissue preparation, slicing, and staining, and dynamic cell imaging (DCI) added the viability information of cells/tissue, which could be more important in sample rapid evaluation.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Light-CT, a special-designed pathology-approximation system which is based on the lighting feature or dynamic feature of tissue and cells, is used to detect malignant cells or tissue in fresh specimens. Morphological structure and pathological changes could be captured in minutes, which implies a possible application in intraoperative diagnosis. The investigators aimed to evaluate the diagnostic efficacy of FFOCT for the tissue samples obtained from EUS-FNB of pancreas.

full-field optical coherence tomography

Pancreatic tissue sample obtained by EUS-FNB will be used for FFOCT imaging. The Images will be sent to trained pathologists for diagnosis. The same tissue sample will be sent to the pathology department for routine histological examination. Compare the diagnoses made by the 2 different methods.
