BACKGROUND/AIM: Tumor biopsy are needed frequency for accurate diagnosis. However, percutaneous liver tumor biopsy presents a risk of complications such as bleeding and tumor seeding. We investigated the feasibility of liver tumor biopsy, followed by cauterization with expandable radiofrequency ablation.
Tumor biopsies using a co-access needle were performed in 102 patients. Expandable radiofrequency ablation was used to ensure cauterization and hemostasis of the puncture route. We evaluated the clinical background and complications.
The average (±standard deviation) tumor diameter was 56.87±39.45 mm. Pathological diagnosis was possible in all cases. In 20 patients, the postoperative pathological diagnosis differed from the preoperative diagnosis. No significant anemia progression was observed in any patients after biopsy, and no peritoneal seeding was observed during a mean follow-up observation period of 18.5 months.
Liver tumor biopsy, followed by cauterization with expandable radiofrequency ablation via a co-access needle, is safe and useful for obtaining reliable diagnoses.
背景/目的：为准确诊断，需要频繁进行肿瘤活检。然而，经皮肝肿瘤活检存在出血和肿瘤种植等并发症风险。我们研究了肝肿瘤活检后用可扩张射频消融进行烧灼的可行性。
对102例患者使用共接入针进行肿瘤活检。使用可扩张射频消融确保穿刺路径的烧灼和止血。我们评估了临床背景和并发症。
肿瘤平均直径（±标准差）为56.87±39.45毫米。所有病例均可行病理诊断。20例患者术后病理诊断与术前诊断不同。活检后所有患者均未观察到明显的贫血进展，在平均18.5个月的随访观察期内未观察到腹膜种植。
肝肿瘤活检后通过共接入针用可扩张射频消融进行烧灼，对于获得可靠诊断是安全且有用的。
