目的:探讨CT导引下腹部细针穿刺抽吸活检技术方法并评价其临床应用。材料与方法:男20例,女7例,年龄7～88岁。穿刺部位包括肝内肿物10例,胰头肿物3例,脾脏肿物、肾脏病灶各1例,腹、盆腔内肿物9例,腹膜后肿物3例。使用岛津SCT3000TC全身CT扫描机作导引,选用18-22G(150mm)Chiba活检针,选择最佳层面、进针路径及取材点穿刺抽吸。结果:腹部细针穿刺抽吸活检阳性率88.9％,2例首次活检为阴性结果,再次活检得到阳性结果,首次活检阳性率82.8％。无任何并发症。结论:CT导引下腹部细针穿刺抽吸活检正确率高、安全,活检方法简便、实用,可为临床制定治疗方案提供可靠依据。
Objective: To investigate the CT-guided lower abdomen needle aspiration biopsy technique and evaluate its clinical application. Materials and Methods: 20 males and 7 females, aged 7 to 88 years. The puncture site included 10 cases of intrahepatic tumor, 3 cases of pancreatic head tumor, 1 case of spleen and kidney disease, 9 cases of abdominal and pelvic tumor, and 3 cases of retroperitoneal tumor. Shimadzu SCT3000TC whole body CT scanner as a guide, the choice of 18-22G (150mm) Chiba biopsy needle, select the best level, the needle path and take the point of puncture and aspiration. Results: The positive rate of fine needle aspiration biopsy in the abdomen was 88.9%. The first biopsy was negative in 2 cases and the positive result was obtained by biopsy again. The positive rate of first biopsy was 82.8%. No complications. Conclusion: CT guided abdominal fine needle aspiration biopsy accuracy, safety, biopsy method is simple and practical, which can provide a reliable basis for the clinical development of treatment options.
