本文总结了灰阶超声诊断61例胰腺(包括14例)壶腹肿瘤,均经手术和病理证实,良性4例,恶性57例,总符合率91.8％,误、漏诊5例,因检查者经验不足,仪器分辨率低和患者胃肠胀气干扰等。描述了本组胰腺及壶腹肿瘤声象图的特点,主要观察胆系扩张情况,本组胰头肿瘤胆系扩张88.4％(23/26),壶腹肿瘤胆系扩张(14/14)。所见肿瘤的形态、边缘、内部和后壁回声的不同表现。良性肿瘤多数边缘清楚、规则、內部呈均匀低回声,后壁回声增强(3/4)。恶性肿瘤中大多数边缘模糊,不规则、内部呈不均匀性弱回声,后壁回声表减(46/52)。本组观察到胰腺及壶腹肿瘤对其后方血管的挤压情况,阐述了胰腺及壶腹肿瘤应与周围脏器和组织的肿瘤相鉴别等项进行分析讨论。灰阶超声诊断方法简便安全易行,可反复检查,又能在动态下观察肿瘤所在部位,形态、大小、边缘、内部结构及回声特征,为临床提供较可靠的诊断依据与治疗措施的选择。
This article summarizes the gray-scale ultrasound diagnosis of 61 cases of pancreatic tumors (including 14 cases) ampulla tumors, were confirmed by surgery and pathology, benign in 4 cases, 57 cases of malignant, with a total compliance rate of 91.8%, 5 cases of misdiagnosis, due to the examiner experience Inadequate, low instrument resolution and patient flatulence interference. The characteristics of pancreatic and ampullary tumors in this group were described. The biliary dilatation was mainly observed. The gallbladder dilatation was 88.4% (23/26) in the pancreatic head and the bile duct dilatation in the ampullary tumor (14/14). The different appearances of the tumor’s morphology, margins, internal and posterior wall echoes. Most of the benign tumors were well-defined, regular, and uniformly hypoechoic at the edges, and had enhanced posterior wall echo (3/4). Most of the malignancies have ambiguous edges, irregular, inhomogeneous internal weak echoes, and diminished posterior wall echo (46/52). In this group, the pancreas and ampulla tumors were observed for the compression of their posterior blood vessels. The pancreas and ampullary tumors were analyzed and discussed with respect to the tumors of surrounding organs and tissues. Gray-scale ultrasonic diagnostic method is simple, safe, easy to perform, and can be repeatedly examined. It can also observe the location, shape, size, margin, internal structure and echo features of the tumor under dynamic conditions, providing a more reliable basis for diagnosis and treatment options.
