AbstractIntroductionEndoscopic ultrasound‐guided fine needle aspiration and biopsy (EUS‐FNA, ‐FNB) are the mainstay for tissue diagnosis of pancreatic lesions. Traditionally, FNA was performed for obtaining cytology and also histology if available from the puncture. Since their advent, however, FNB needles have been intended mainly to obtain core biopsies for histological specimens.AimsWe aimed to assess the yield of cytology obtained via both FNA and FNB needles.MethodsA retrospective study was performed including all patients who were diagnosed with pancreatic adenocarcinoma obtained via EUS‐FNA/FNB needles.ResultsOverall, 227 patients were included. Of them, 85 patients underwent FNB, versus 142 patients who had FNA. The average age in the FNB group was 70.46 ± 11.29 years, versus 71.44 ± 11.80 in the FNA group, P = 0.57. Notably, cytological analysis diagnosed malignancy equally in both groups (69.4% in the FNB group, vs. 65.5% in the FNA group). The compatibility rate of cytology with histology was 76.5% in the FNB group, versus 76.1% in the FNA group (P = 0.69). The agreement level between cytology obtained by FNA and FNB, versus histology obtained by both needles, was moderate (kappa = 0.48, 95% CI 0.39‐0.57). Similarly, the agreement level between cytology and histology in the FNB group was moderate as well (kappa = 0.5, 95% CI 0.36‐0.64).ConclusionCytological assessment yielded an equal performance as compared to histological assessment with both needles. We recommend obtaining cytology specimens in pancreatic solid lesion puncture by FNB needle.
