CT引导穿刺活检诊断骨盆肿瘤的临床研究

CT Guided Puncture Biopsy in the Diagnosis of Pelvic Tumor Clinical Research

目的:评估CT引导下穿刺活检诊断骨盆肿瘤的临床研究价值。方法:回顾性分析2012年12月至2016年2月在CT引导下经皮穿刺活检的42例骨盆肿瘤,患者经扫描定位,选择最佳进针层面与路径,采用11G骨活检针或16G软组织同轴套管全自动活检针,局麻后将穿刺针刺入病灶,获取足量病理组织标本,10%甲醛固定或新鲜标本,送病理科检查。结果:42例患者都安全穿刺至病变部位取出相应的病理标本,穿刺活检准确率、成功率100%;经手术及对患者进行随访后,病理学检查确诊率95.2%,其中1例穿刺活检病理畸胎瘤手术后病理为粘液腺癌浸润,1例穿刺活检病理多形性横纹肌肉瘤手术后病理为恶性纤维组织细胞瘤;其余穿刺活检病理与手术后病理一致。结论:CT引导下穿刺活检诊断骨盆肿瘤准确、安全、有效,且并发症极少,对解剖较深、结构复杂,血管组织丰富的骨盆肿瘤尤为适用。

Objective： To evaluate CT guided puncture biopsy in the diagnosis of pelvic tumor clinical research value. Methods： a retrospective analysis of December 2012- 2016 February in CT guided by percutaneous puncture biopsy of 42 cases of pelvic tumor, patients after CT localization, the best needle level and path, the 11g bone biopsy needle or 16g soft tissue sleeve coaxial automatic biopsy needle, after local anesthesia will puncture needle into the lesion, lo obtain a sufficient amount of pathological tissue specimens, fixed in 10% formalin or fresh specimens, send disease science examination. Results： 42 cases patients safety puncture to lesions removed the pathological Specimens, biopsy accuracy rate, the success rate of 100%; alter operation and the patients were followed up. The pathological diagnosis rate was 95.2%, including 1 cases of biopsy teratoma after operation pathologic raucous adenocarcinoma invasion, I cases biopsy pathological pleomorphic rhabdomyosarcoma after surgery disease for malignant fibrous histiocytoma; after the rest of the biopsy and surgical pathology. Conclusion： CT guided puncture biopsy in the diagnosis of pelvic tumor accurate, sate and effective and little complication. The anatomy of the deep, complex structure, rich in vascular tissue of pelvic tumors especially for applicable.
