多层螺旋CT在胰腺癌诊治中的临床价值

目的探究胰腺癌术前使用多层螺旋CT检查对临床诊断指导价值。方法回顾性分析2016年8月到2019年4月期间在我院进行检查治疗的69例胰腺癌患者术前影像学检查资料。患者接受多层螺旋CT检查,其后接受手术并进行病灶病理检测。分析多层螺旋CT检查胰腺癌影像学表现,对多层螺旋CT影像分期与病理诊断分期结果进行比较。结果多层螺旋CT平扫结果可见患者胰腺出现肿大现象,可以明显观察到患者病灶内部密度不均匀,病灶表现为不规则,增强扫描可见患者胰腺实质存在低密度影,同时胰腺癌会累及周围组织与器官;多层螺旋CT诊断胰腺癌分期结果为:肿瘤分期Ⅰ期、Ⅱ期、Ⅲ期、Ⅳ期分别18例、16例、16例和9例,其与病理检测分期结果比较差异没有统计学意义(P>0.05);以病理检查作为"金标准",多层螺旋CT诊断胰腺癌准确度为85.51%,神经浸润诊断准确度为86.96%,淋巴转移诊断准确度为58.57%。结论多层螺旋CT可用于术前诊断肿瘤分期,判断胰腺癌神经浸润、淋巴转移,可为后期手术方案制定提供重要依据。

Clinical Diagnosis and Guidance Value of Multi-slice Spiral CT Before Pancreatic Cancer Surgery

Objective To investigate the clinical diagnosis and guidance value of multi-slice spiral CT(MSCT)before pancreatic cancer surgery.Methods A retrospective analysis was performed on the preoperative imaging examination data of 69 patients with pancreatic cancer who underwent examination and treatment in the hospital from August 2016 to April 2019.The patient underwent MSCT.Then,su rgery was conducted,the pathological examination on lesions was performed.The imaging findings of pancreatic cancer examined by MSCT were analyzed.The imaging stage results and diagnosis results detected by MSCT and pathological examination were compared.Results The results of the MSCT scan showed that there was a swelling phenomenon in the pancreas of patients.It was ebvious that the internal density of lesions was uneven,and lesions showed irregular shapes.The enhanced scan showed that there was low-density shadow in the pancreatic parenchyma of patients.Peripheral tissues and orga ns would be involved by pancreatic cancer.The diagnostic results of pancreatic cancer staging by MSCT:There were 18 cases,16 cases,16 cases,and 9 cases with tumor stageⅠ,Ⅱ,Ⅲ,and IV,respectively.The re was no significa nt difference compa red with staging results of pathological detection(P>0.05).Ta king pathological examination as golden standard,The accu ra cies of MSCT for diagnosis of pancreatic cancer,nerve infiltration and lymphatic metastasis were 85.51%,86.96%,and 58.57%,respectively.Conclusion MSCT can be applied for preoperative diagnosis of tumor staging,judging the nerve invasion and lymph node metastasis of pancreatic cancer.It is of crucial guiding significance for the development of postoperative surgical plans.
