Methods A systematic search of literature from the PubMed database was conducted for identifying eligible studies on implantation of thyroid hyperplastic or neoplastic cells after endoscopic thyroid surgery. Results Overall, 5 reported cases on patients suffering from endoscopic thyroid surgery with implantation of thyroid hyperplastic or neoplastic cells were included in the systematic review. Conclusions Unskilled surgeons, rough intraoperative surgical treatment, scarification or rupture of tumor, contamination of instruments, chimney effect, aerosolization of tumor cells may be associated with the implantation after endoscopic thyroidectomy. To minimize the risk of such complication, we should be more meticulous and strict the endoscopic surgery indications.展开更多
目的探究并分析1.5 T MR影像特征与腮腺肿瘤病人良恶性诊断的关系及病理结果。方法选取2016年5月~2019年5月收治的早期腮腺肿瘤患者70例,所有患者均在我院进行1.5 T MR检查,并经病理诊断确诊。其中良性肿瘤51例(良性肿瘤组),恶性肿瘤19...目的探究并分析1.5 T MR影像特征与腮腺肿瘤病人良恶性诊断的关系及病理结果。方法选取2016年5月~2019年5月收治的早期腮腺肿瘤患者70例,所有患者均在我院进行1.5 T MR检查,并经病理诊断确诊。其中良性肿瘤51例(良性肿瘤组),恶性肿瘤19例(恶性肿瘤组)。分析并比较良恶性肿瘤的MR及病理结果、良恶性肿瘤MR影像结果特点(包括位置、形态、密度、轮廓)、良恶性组MR时间信号曲线类型及峰值时间。结果MR诊断腮腺肿瘤结果与病理学结果差异无统计学意义(P>0.05);腮腺良恶性肿瘤MR影像学结果比较,差异有统计学意义(P<0.05),良恶性肿瘤在位置、形态、密度、轮廓等表现差异均具有统计学意义(P<0.05);两组肿瘤MR动态特点比较,差异具有统计学意义(P<0.05),良性组持续型、廓清型(廓清率≥0.3%)、平坦型比率高于恶性组(P<0.05),恶性组廓清型(廓清率<0.3%)比率高于良性组(P<0.05),良性组峰值时间高于对照组,差异具有统计学意义(P<0.05)。结论1.5T MR在腮腺肿瘤病人良恶性诊断中具有较高的诊断效能,对于良恶性肿瘤的鉴别具有较大的价值,值得临床推广。展开更多
