To compare performance assessment between 20G double fine needle biopsy (FNB) and conventional 22G fine needle aspiration (FNA) needles for endoscopic ultrasound (EUS)-guided biopsy.<\/p>\n\n\n\n
This prospective study examined 20 patients who underwent the random puncture of solid pancreatic lesions with both needles and the analysis of tissue samples by a single pathologist.<\/p>\n\n\n\n
The ProCore 20G FNB needle provided more adequate tissue samples (16 vs. 9, p=0.039) with better cellularity quantitative scores (11 vs. 5, p=0.002) and larger diameter of the histological sample (1.51\u00b11.3 mm vs. 0.94\u00b10.55 mm, p=0.032) than the 22G needle. The technical success, puncture difficulty, and sample bleeding were similar between groups. The sensitivity, specificity, and diagnostic accuracy were 88.9%, 100%, and 90% and 77.8%, 100%, and 78.9% for the 20G and 22G needles, respectively.<\/p>\n\n\n\n
The samples obtained with the ProCore 20G FNB showed better histological parameters; although there was no difference in the diagnostic performance between the two needles, these findings may improve pathologist performance.<\/p>","protected":false},"excerpt":{"rendered":"
