OBJECTIVE: Endoscopic ultrasound (EUS)-guided FNB was not demonstrated to be better than EUS fine-needle aspiration (FNA) to obtain adequate samples for diagnosis of pancreatic tumors. We report our experience using a 22-gauge needle aspiration to obtain both cytologic and histologic samples.

PATIENTS AND METHODS: In a total of 232 patients (51% men), 22-gauge needles (Cook Medical) were used to obtain a cytological sample (between 2008 and 2016, Cohort A) and a cytologic and a histologic sample (between 2016 and 2019, Cohort B) to evaluate the usability of this needle to collect material for cytologic and histologic examination. MOSE was used.

RESULTS: Pancreatic adenocarcinoma was diagnosed in 76/113 (68%) patients in Cohort A and in 88/119 (74%) in Cohort B. Non-diagnostic sampling occurred in 30/113 (26%) patients in Cohort A and in 25/119 (21%) in Cohort B. The median number of passages was three in both cohorts. Lesions were in the head/uncinated process 57% vs. 51% and body/tail 43% vs. 49% in Cohorts A and B, respectively; the mean tumor size was 34.5 mm (SD 10.7) in Cohort A and 35.4 mm (SD 14.7) in Cohort B.

CONCLUSIONS: FNA needle (22-gauge) with adequate passes, MOSE determination and adequate processing of specimens, provided FNA and FNB specimen collection.
