Improved diagnostic yield of endoscopic ultrasound-fine needle biopsy with histology specimen processing

Endoscopic ultrasound-guided fine needle biopsy (EUS-FNB) has emerged as a safe, efficacious alternative to fine needle aspiration (FNA) for tissue acquisition. EUS-FNB is reported to have higher diagnostic yield while preserving specimen tissue architecture. However, data on the optimal method of EUS-FNB specimen processing is limited.To evaluate EUS-FNB with specimen processing as histology vs EUS-FNA cytology with regards to diagnostic yield...
