Endoscopic ultrasound (EUS) enables a gastroenterologist to sample the masses of the middle and inferior mediastinum, which are adjacent to the esophagus; cystic or solid lesions of the pancreas, which are adjacent to the stomach and duodenum; and perirectal lesions. Needles used for EUS sampling include aspiration (19, 20, and 22 Gauge) or core biopsy needles (ProCore and Trucut) (19, 20, and 22 Gauge). The type and size of EUS needles do not alter the diagnostic results. Rapid on-site cytopathological evaluation will increase the diagnostic efficacy to 100% without prolonging the procedure time. Diagnostic efficacy of EUS-guided fine-needle aspiration or core biopsy depends on the experience of an endoscopist and a cytopathologist. In the presence of an experienced endoscopist and cytopathologist, the size of the needle does not have any significant impact on the diagnostic success.
内镜超声检查（EUS）使胃肠病学家能够对与食管相邻的中纵隔和下纵隔肿物、与胃和十二指肠相邻的胰腺囊性或实性病变以及直肠周围病变进行取样。用于EUS取样的针包括抽吸针（19号、20号和22号）或粗针活检针（ProCore和Trucut）（19号、20号和22号）。EUS针的类型和尺寸不会改变诊断结果。快速现场细胞病理学评估可将诊断效率提高到100%，且不会延长操作时间。EUS引导下细针抽吸或粗针活检的诊断效率取决于内镜医师和细胞病理学家的经验。在有经验丰富的内镜医师和细胞病理学家的情况下，针的尺寸对诊断成功率没有任何显著影响。
