■恶性病因在70-80%的症状性腹膜后肿块中发现。组织学是诊断和治疗所必需的。有关内窥镜超声(EUS)引导的组织采集(EUS-GTA)的信息很少用于腹膜后肿块。本研究旨在评估EUS-GTA诊断腹膜后肿块的病理结果。
■这次回顾展,多中心研究涉及来自5个护理中心的患者。所有接受EUS评估的腹膜后肿块患者均被纳入。我们记录了人口统计学和临床特征,质量的位置和大小,针头类型(FNA/FNB),和手术相关的并发症。
■共纳入43例患者。中位年龄为50.5岁(范围:23-83岁),女性22人(51.2%)。首发症状为腹痛23例(52.3%),体重减轻11例(25%)。33例(75%)患者的初始成像是通过计算机断层扫描进行的。67.5%(29/43)的病例达到EUS-GTA诊断。最常见的组织学诊断是癌,25.5%(11/43)。在31(72%)中发现了恶性病因:20是腹膜后的原发性肿瘤,和11转移。在有转移的患者中,避免了手术,并表明了药物治疗。未报告不良事件。
■EUS和EUS-GTA通常可以提供准确的组织诊断,并显着影响后续管理。
UNASSIGNED: Malignant etiologies are found in 70-80% of symptomatic retroperitoneal masses. Histology is required for diagnosis and treatment. Information about endoscopic ultrasound (EUS)-guided tissue acquisition (EUS-GTA) is scant for retroperitoneal masses. This
study aimed to assess the pathology results of EUS-GTA for diagnosing retroperitoneal masses.
UNASSIGNED: This retrospective, multicenter
study involved patients from 5 care centers. All patients with retroperitoneal masses who underwent EUS evaluation were enrolled. We recorded demographic and clinical characteristics, location and size of the mass, type of needle (FNA/FNB), and complications related to the procedure.
UNASSIGNED: A total of 43 patients were included. The median age was 50.5 (range: 23-83) years, and 22 (51.2%) were female. The initial symptom was abdominal pain in 23 (52.3%) cases and weight loss in 11 (25%). Initial imaging was by computed tomography in 33 (75%) patients. Diagnosis with EUS-GTA was reached in 67.5% (29/43) cases. The most frequent histological diagnosis was carcinoma, in 25.5% (11/43). A malignant etiology was found in 31 (72%): 20 were primary tumors from the retroperitoneum, and 11 were metastases. In patients with metastasis, surgery was avoided and medical treatment was indicated. No adverse events were reported.
UNASSIGNED: EUS and EUS-GTA can frequently provide accurate tissue diagnosis and significantly impact the subsequent management.
