摘  要:目的 评价超声对≤ 2 .0cm胰腺小肿瘤的诊断价值 ,探讨困扰超声对胰腺小肿瘤检出率的问题所在。方法 对经手术病理证实的≤ 2 .0cm的胰腺小肿瘤 35例进行回顾性分析。结果 胰岛细胞瘤 30例 ,胰腺癌 3例 ,炎性假瘤 1例 ,结核结节 1例 ;肿瘤 1.0~ 2 .0cm的超声检出率为 6 0 % ( 18/30 ) ;直径≤ 1.0cm的检出率为 40 % ( 2 /5 ) ;超声总检出率为5 7% ( 2 0 /35 )。漏诊率为 43 % ( 15 /35 )。结论 超声检出 1.0~ 2 .0cm的胰腺小肿瘤并不困难 ,检出≤ 1.0cm的微小肿瘤也有可能。影响超声对胰腺小肿瘤检出率的因素为病人就诊时间的早晚、肿瘤位置、回声特性、仪器性能、操作者经验等。Objective To evaluate the value of ultrasonography in the diagnosis of small (≤2.0cm) pancreatic tumors and investigate the reason to affect the detection rate of small pancreatic tumors. Methods Thirty-five patients with small pancreatic tumors confirmed by operation and pathology were analyzed retrospectively. Results Of 35 cases, 30 cases were islet tumor, 3 cases pancreatic carcinoma, one inflammatory pesudotumor, one tubercle. The detection rate of ultrasonography in the pancreatic tumors with diamter in 1.0-2.0cm was 60% (18/30), the detection rate of the pancreatic tumors with diameter in ≤1.0cm was 40%(2/5), the total detection rate of the pancreatic tumors was 57%(20/35), the rate of missed diagnosis was 43%(15/35). Conclusion It was suggested that ultrasonography provide diagnostic value for small (≤2.0cm) pancreatic tumors. The major reasons to affect the detection rate of pancreatic tumor were the examination stage of patient, the site of tumor, property of instrument and the experience of examiner.[
