摘要
目的:探讨胰腺实性假乳头状瘤的超声诊断特征。方法:选择2015年1月~2019年5月在本院行胰腺肿块切除术治疗的20例病理诊断胰腺实性假乳头状肿瘤患者作为研究对象。术后收集患者病理诊断结果和术前超声诊断结果,对比两组结果符合情况,并分析超声检查的肿瘤特征。结果:彩色超声诊断结果与术后病理诊断比较显示,误诊率为35.00%,漏诊率为0,与病理诊断符合率65.00%。所有肿瘤均为单发,边界清晰,肿瘤最大直径为35~78mm,平均(56.03±21.03)mm。肿瘤生长部位以胰头部和胰尾部为主,肿瘤形态以类圆形和椭圆形为主,胰腺肿块多存在包膜回声,后方无回声衰减。肿瘤内部回声以实性回声为主,囊性回声和囊/实兼备者较少。主胰管扩张情况观察可见,无扩张者占比最高,明显扩张和轻度扩张者较少。血流信号探查显示,多数肿块内存在少许血流信号。肿瘤多无钙化,仅少量伴钙化。肿瘤未侵犯肠系膜血管、脾动静脉及其他腹腔静脉。结论:超声检查对胰腺实性假乳头状瘤的诊断有一定价值,可联合肿瘤特征分析,进一步提高超声诊断准确性。
Objective:To explore the characteristics of ultrasound diagnosis of solid pseudopapillary tumors of the pancreas.Methods:From January 2015 to May 2019,20 patients with pathologically diagnosed solid pseudopapillary tumors of the pancreas who underwent pancreatic mass resection in our hospital were selected as the research subjects.Postoperative pathological diagnosis results and preoperative ultrasound diagnosis results were collected,the results of the two groups were compared,and the tumor characteristics of ultrasound examination were analyzed.Results:The comparison of color ultrasound diagnosis results with postoperative pathological diagnosis showed that the misdiagnosis rate was 35.00%,the missed diagnosis rate was 0,and the coincidence rate with pathological diagnosis was 65.00%.All tumors are single,with clear boundaries,and the maximum diameter of the tumor is 35~78 mm,with an average of(56.03±21.03)mm.The tumor growth site is dominated by the head and tail of the pancreas,and the tumor morphology is mainly round and oval.The pancreatic mass mostly has capsule echo,and there is no echo attenuation in the rear.The internal echo of the tumor is mainly solid echo,and there are few cystic echo and cystic/solid.Observation of the dilatation of the main pancreatic duct shows that those without dilation have the highest proportion,and those with obvious dilation and mild dilation are fewer.Probing of blood flow signals showed that there were some blood flow signals in most lumps.Most tumors have no calcification,and only a small amount is accompanied by calcification.The tumor did not invade the mesenteric blood vessels,splenic arteriovenous and other celiac veins.Conclusion:Ultrasound examination has certain value in the diagnosis of pancreatic solid pseudopapillary tumors.It can be combined with the analysis of tumor characteristics to further improve the accuracy of ultrasound diagnosis.
