EUS-guided FNA (EUS-FNA) has a high diagnostic accuracy for pancreatic diseases. However, although most reports have typically focused on cytology, histological tissue quality has rarely been investigated. The effectiveness of EUS-FNA combined with high negative pressure (HNP) suction was recently indicated for tissue acquisition, but has not thus far been tested in a prospective, randomized clinical trial.
To evaluate the adequacy of EUS-FNA with HNP for the histological diagnosis of pancreatic lesions by using 25-gauge needles.
Prospective, single-blind, randomized, controlled crossover trial.
Seven tertiary referral centers.
Patients referred for EUS-FNA of pancreatic solid lesions. From July 2011 to April 2012, 90 patients underwent EUS-FNA of pancreatic solid masses by using normal negative pressure (NNP) and HNP with 2 respective passes. The order of the passes was randomized, and the sample adequacy, quality, and histology were evaluated by a single expert pathologist.
EUS-FNA by using NNP and HNP.
The adequacy of tissue acquisition and the accuracy of histological diagnoses made by using the EUS-FNA technique with HNP.
We found that 72.2% (65/90) and 90% (81/90) of the specimens obtained using NNP and HNP, respectively, were adequate for histological diagnosis (P = .0003, McNemar test). For 73.3% (66/90) and 82.2% (74/90) of the specimens obtained by using NNP and HNP, respectively, an accurate diagnosis was achieved (P = .06, McNemar test). Pancreatitis developed in 1 patient after this procedure, which subsided with conservative therapy.
This was a single-blinded, crossover study.
Biopsy procedures that combine the EUS-FNA with HNP techniques are superior to EUS-FNA with NNP procedures for tissue acquisition. (

超声内镜引导下细针穿刺抽吸术（EUS-FNA）对胰腺疾病具有较高的诊断准确性。然而，尽管大多数报告通常聚焦于细胞学检查，但组织学组织质量很少被研究。最近有研究表明，EUS-FNA联合高负压（HNP）抽吸在获取组织方面具有有效性，但迄今为止尚未在前瞻性随机临床试验中得到验证。
使用25G穿刺针评估EUS-FNA联合HNP对胰腺病变进行组织学诊断的充分性。
前瞻性、单盲、随机、对照交叉试验。
7家三级转诊中心。
因胰腺实性病变接受EUS-FNA检查的患者。2011年7月至2012年4月，90例患者分别使用正常负压（NNP）和HNP对胰腺实性肿块进行EUS-FNA，各穿刺2次。穿刺顺序随机，样本的充分性、质量和组织学由一名专业病理专家评估。
使用NNP和HNP进行EUS-FNA。
使用EUS-FNA联合HNP技术获取组织的充分性以及组织学诊断的准确性。
我们发现，分别使用NNP和HNP获取的标本中，72.2%（65/90）和90%（81/90）足以进行组织学诊断（McNemar检验，P = 0.0003）。分别使用NNP和HNP获取的标本中，73.3%（66/90）和82.2%（74/90）获得了准确诊断（McNemar检验，P = 0.06）。1例患者术后发生胰腺炎，经保守治疗后缓解。
这是一项单盲交叉研究。
EUS-FNA联合HNP技术的活检程序在获取组织方面优于EUS-FNA联合NNP程序。（临床试验注册号：UMIN000005939。）
