The outcome of CT-guided biopsy in patients with suspected retroperitoneal fibrosis (RF), regarded as technically challenging, remains unclear. This study aimed to evaluate the results of CT-guided biopsy in patients with lesions considered in the differential diagnosis of RF and compare them with results from patients with other retroperitoneal lesions.
Patients who underwent CT-guided biopsy of retroperitoneal lesions between January 2010 and September 2018 were retrospectively reviewed. The study cohort with retroperitoneal lesions surrounding the infra-abdominal aorta, iliac vessels, and/or ureters was divided into two groups: Group F included patients with lesions for which RF was considered in the differential diagnosis, and Group C comprised patients with a retroperitoneal mass or lymphadenopathy. Lesion size and depth, and biopsy details including technical success, position, procedure time, diagnostic yield, and complications between the two groups were compared.
Group F included 27 patients (mean age 68.5 years ± 11.6, 17 male) and Group C 30 patients (mean age 65.0 years ± 11.8, 16 male). The short axis was significantly smaller in Group F than in Group C (19 mm vs 26 mm, P = 0.041), and procedure time was significantly longer in Group F than in Group C (31.5 min ± 13.2 vs 20.3 min ± 8.4, P = 0.001). Technical success rate (93% vs 100%), accuracy (93% vs 93%), and complications (3.7% vs 10%) between Groups F and C were not significantly different.
CT-guided biopsy of patients with suspected RF is considered safe and effective.
对于疑似腹膜后纤维化（RF）患者，CT 引导下活检的结果（被认为具有挑战性）仍不清楚。本研究旨在评估 CT 引导下活检在疑似 RF 患者中的结果，并将其与其他腹膜后病变患者的结果进行比较。
回顾性分析 2010 年 1 月至 2018 年 9 月期间接受 CT 引导下腹膜后病变活检的患者。将围绕下腹部主动脉、髂血管和/或输尿管的腹膜后病变患者分为两组：F 组包括 RF 鉴别诊断的病变患者，C 组包括腹膜后肿块或淋巴结病变患者。比较两组间病变大小和深度、活检详细信息，包括技术成功率、位置、操作时间、诊断率和并发症。
F 组包括 27 例患者（平均年龄 68.5±11.6 岁，17 例男性），C 组包括 30 例患者（平均年龄 65.0±11.8 岁，16 例男性）。F 组的短轴明显小于 C 组（19mm 比 26mm，P=0.041），F 组的操作时间明显长于 C 组（31.5min±13.2 比 20.3min±8.4，P=0.001）。F 组和 C 组的技术成功率（93%比 100%）、准确性（93%比 93%）和并发症（3.7%比 10%）差异无统计学意义。
CT 引导下活检疑似 RF 患者是安全有效的。
