胰腺导管腺癌和肿块型胰腺炎CT对比分析

【摘要】 目的探讨胰腺导管腺癌和肿块型胰腺炎的CT特征。方法选取2009年5月～2011年5月经手术病理证实为胰腺导管腺癌的患者22例和肿块型胰腺炎的患者24例,对其CT诊断资料进行回顾性分析。结果肿块型胰腺炎与胰腺导管癌比较,CT征象中沿主胰管走向分布钙化灶(40.0%、0%)、肝转移(0%、25.0%)、腹部淋巴结肿大(0%、33.3%)、胰周大血管包埋包绕侵袭(0%、50.0%)、腹膜后直接侵犯(0%、50.0%)、胆管与胰管均扩张(13.6%、41.7%)、胆总管下段扩张呈现出突然狭窄截断(18.2%、75.0%)比较差异有统计学意义(P<0.05)。结论将胰腺导管腺癌和肿块型胰腺炎的CT征象合其临床表现、病史及实验室检查等,能进行准确、有效地诊断与鉴别诊断,但CT表现无异常的患者不能完全排除存在胰腺癌的可能,需要进一步结合临床确诊。更多还原

【Abstract】 Objective To observe computer tomography(CT) features of pancreatic ductal adenocarcinoma and pancreatitis.Methods The data of CT diagnosis in 22 cases with pancreatic ductal adenocarcinoma and 24 cases with pancreatitis in our hospital from May 2009 to May 2011 were retrospectively analyzed.Results Mass in pancreatitis and pancreatic ductal carcinoma CT signs along the main pancreatic duct to the distribution of calcification(40.0%,0%),liver metastases(0%,25.0%),abdominal lymph nodes(0%,33.3%)peripancreatic great vessels embedded surrounding the invasion(0%,50.0%),a direct violation of retroperitoneal(0%,50.0%),bile duct and pancreatic duct dilatation(13.6%,41.7%),common bile duct expansion showingsuddenly narrow truncated(18.2%,75.0%) difference there is statistically significant(P<0.05).Conclusion Pancreatic ductal adenocarcinoma and pancreatitis of CT signs and its clinical manifestation,medical history and laboratory examination,can accurately,effectively and differential diagnosis,but CT showed no abnormalities in patients cannot completely exclude the presence of pancreatic cancer may,require further combined with clinical diagnosis.更多还原
