Beskrivelse
Inclusion Criteria:
- Patients older than 20 years referred to our medical center for EUS-FNA or FNB with diagnosed or suspected solid pancreatic masses according to clinical evaluation and imaging studies
Exclusion Criteria:
- cystic pancreatic lesions, patients haemodynamically unstable or with severe coagulopathy (international normalized ratio [INR] > 1.5 or platelet count < 50,000 cells/cubic millimeter [cmm3]), patients unable to suspend anticoagulant/anti-platelet therapy, pregnancy, inability or refusal to give informed consent, and refusal to participate in the study.

Tidsramme |
|---|---|---|
|
accessing the rate for procurement of the histologic core
Tidsramme: up to 5 minuites after endoscopic ultrasound-guided fine needle biopsy
|
The tissue samples were immediately fixed in formalin.
The histologic cassette was processed, embedded in paraffin, and then prepared in hematoxylin and eosin to be evaluated by one pathologist (K.H.K) for the presence of a histologic core.
If the histologic core was present, the specimen was graded as optimal or suboptimal.
Optimal specimens were those in which the procured material enabled satisfactory assessment of histologic architecture that either did not change the original diagnosis or yielded additional findings.
Suboptimal specimens were those in which the quality of the histologic core was unsatisfactory for assessment of histologic architecture.
When required, immunohistochemical or special staining was performed for differentiation of morphologically challenging lesions.10
