目的探讨超声引导下穿刺活检对早期肝癌的诊断价值。方法对43例影像学检查不能确诊且直径<3.0 cm的肝脏小结节患者进行超声引导下穿刺活检,并与术后病理对照(肝内转移性病灶复查影像学证实)。结果 43例均一次性取材成功,无明显并发症发生;术后病理显示:原发性肝细胞癌32例,毛细胆管癌2例,局灶性脂肪肝1例,肝血管瘤2例,肝硬化结节2例,影像学复查示转移性肝癌4例,超声引导下穿刺活检把1例原发性肝细胞癌误诊为肝硬化结节,正确诊断率为97.67%(42/43)。结论超声引导下穿刺活检对早期肝癌的诊断具有重要临床应用价值。
Objective To investigate the value of ultrasound-guided needle biopsy in the diagnosis of early stage liver cancer. Methods Thirty - six patients with small nodules whose diameter was less than 3.0 cm were diagnosed by imaging examination and were performed ultrasound - guided biopsy. The pathologic findings were compared with those after operation. Results All the 43 cases were successfully obtained without obvious complication. Pathology showed that there were 32 cases of primary hepatocellular carcinoma, 2 cases of capillary cholangiocarcinoma, 1 case of focal fatty liver, 2 cases of hepatic hemangioma, In 2 cases of sclerosis nodules, 4 cases of metastatic liver cancer were retrospectively analyzed by imaging, and 1 case of primary hepatocellular carcinoma was misdiagnosed as cirrhosis nodule by puncture biopsy. The correct diagnosis rate was 97.67% (42/43). Conclusion Ultrasound-guided biopsy has important clinical value in the diagnosis of early-stage liver cancer.
