Abstract
BACKGROUND:Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is effective for tissue diagnosis of pancreatic mass. To improve diagnostic yield and drawbacks, 22-gauge (G) core biopsy (FNB) needle has been developed. This study aims to compare 22G FNA and FNB needles for EUS-guided sampling of suspected pancreatic cancer. METHODS: This is a randomized controlled crossover trial. A total of 60 patients with suspected unresectable pancreatic cancer referred for EUS-guided sampling were randomly assigned to two groups. Both groups had 22G FNA and FNB needles performed in a randomized order. The primary endpoint was the cytological, histological and overall diagnostic accuracy of pancreatic cancer. RESULTS: FNA and FNB needles reported similar level of diagnostic accuracy (FNA needle 95% vs. FNB needle 93.3%; p = .564), and it was not statistically different. However, cytological cellularity was significantly higher in the FNB needles compared to FNA needles (odds ratio 2.75, 95% confidence interval (CI)). There were no procedure-related complications in both needles. CONCLUSIONS: The diagnostic accuracy of EUS-guided sampling for pancreatic cancer using 22G FNA is comparable to FNB needles. The cytological quality of specimen is better in the FNB needle.
