The current article showed that endoscopic ultrasound-guided fine-needle aspiration biopsy (EUS-FNAB) is a powerful modality with which to obtain samples from small (≤ 25 mm) and large lesions with no difference in yield of samples (96 % vs. 96%) from the two groups. Most of the adequate samples for diagnosis of small lesions can be obtained within five passes irrespective of the organ site. The overall sensitivity (96% vs. 96%), specificity (100% vs. 100%), positive predictive value (100% vs. 100%), negative predictive value (96% vs. 91%), and diagnostic accuracy (98% vs. 97%) remained comparable regardless of whether the lesion was small or large. The results showed that EUS-FNAB is a highly accurate modality to obtain samples from small lesions irrespective of the anatomic location.
