Abstract

Background: 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.

Methods: 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.

Results: 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.

Conclusion: EUS and EUS-GTA can frequently provide accurate tissue diagnosis and significantly impact the subsequent management.

内窥镜超声引导下腹膜后肿块组织采集的病理结果：一项多中心研究。

背景：有症状的腹膜后肿块中有 70-80% 是恶性病因。诊断和治疗需要进行组织学检查。有关腹膜后肿块的内窥镜超声（EUS）引导下组织采集（EUS-GTA）的信息很少。本研究旨在评估 EUS-GTA 诊断腹膜后肿块的病理结果：这项多中心回顾性研究涉及 5 个医疗中心的患者。所有接受 EUS 评估的腹膜后肿块患者均被纳入研究。我们记录了人口统计学和临床特征、肿块的位置和大小、穿刺针类型（FNA/FNB）以及与手术相关的并发症：结果：共纳入 43 名患者。中位年龄为 50.5 岁（23-83 岁），女性 22 人（51.2%）。23例（52.3%）患者的最初症状是腹痛，11例（25%）患者体重减轻。33例（75%）患者的最初影像学检查为计算机断层扫描。67.5%的患者（29/43）通过 EUS-GTA 确诊。最常见的组织学诊断是癌，占 25.5%（11/43）。31例（72%）发现恶性病因：20例为腹膜后原发肿瘤，11例为转移瘤。有转移瘤的患者应避免手术，改用药物治疗。无不良反应报告：结论：EUS 和 EUS-GTA 经常能提供准确的组织诊断，并对后续治疗产生重大影响。
