目的:探讨超声检查对于胰腺实性假乳头状瘤(solid-pseudopapillary tumor of the pancreas,SPTs)的诊断价值.方法:回顾性分析经病理证实的30例胰SPTs的超声及超声造影(contrast enhanced ultrasonography,CEUS)表现.将病例分为常规超声组和超声造影两组,利用SPSS18.0软件,用两独立样本2检验的Fisher确切概率法,计算两组方法是否有统计学差异.结果:30例患者中,男性1例,女性29例,年龄30.5岁,其中肿块位于胰头有14例、胰体有4例、胰尾有12例,肿物大小约1.5cm×1.1cm×1.8cm-21cm×11cm×15cm.常规超声组诊断17例,漏诊1例,误诊为胰腺其他肿瘤8例.超声造影组诊断4例,误诊为胰腺其他肿瘤1例.诊断符合率方面:常规超声组65.4%(17/26);超声造影组75%(3/4).两组数据统计结果:P=0.593,说明两种方法之间还不具有统计学差异.结论:SPTs具有一定的声像图定特点及临床特点,特别是CEUS后,了解这些能提高超声对SPTs的诊断水平.
Objective: To investigate the diagnostic value of ultrasonography in detecting solid-pseudopapillary tumor of the pancreas (SPTs) .Methods: Thirty cases of pancreatic SPTs confirmed by pathology were retrospectively analyzed by ultrasonography and contrast enhanced ultrasonography , CEUS) .The cases were divided into two groups: conventional ultrasound group and contrast-enhanced ultrasound, using SPSS18.0 software, Fisher exact test using two independent samples 2 test to calculate whether there is a statistically significant difference between two groups.Results: 30 cases Among the patients, there were 1 males and 29 females, aged 30.5 years. Among them, 14 were located in the head of the pancreas, 4 were in the pancreas, 12 in the pancreas, and were about 1.5 cm × 1.1 cm × 1.8 cm-21 cm in size × 11cm × 15cm.Conventional ultrasound group diagnosed in 17 cases, missed diagnosis in 1 case, misdiagnosed as pancreatic other tumors in 8 cases.Ultrasonography group of 4 cases misdiagnosed as pancreatic other tumors in 1. Diagnostic compliance rate: conventional ultrasound group 65.4% 17/26), and 75% (3/4) in contrast group.The statistical results of two groups of data: P = 0.593, indicating that there is no statistical difference between the two methods.Conclusion: SPTs have certain sonographic features And clinical features, especially CEUS, to understand these can improve the diagnostic ultrasound of SPTs water level.
