摘　　要：目的:探讨16层螺旋CT在直肠癌淋巴结转移临床诊断中的应用效果,结合CT诊断结果进行分析。方法:选取2019年5月~2022年6月本院收治的51例直肠癌患者作为研究对象,应用16层螺旋CT进行诊断,结合CT影像进行分析,判断淋巴结转移的发生、进展情况。结果:直肠癌淋巴结转移患者的病理诊断结果显示良、恶性淋巴结分别为29例和22例,CT诊断结果显示良、恶性淋巴结分别为30例(2例误诊为恶性)和21例(1例误诊为良性),其对于直肠癌淋巴结转移诊断的灵敏度、特异度、准确度为96.55%(28/29)、90.91%(20/22)、94.12%(48/51)。结合CT诊断结果,良性淋巴结患者的淋巴结数量[(3.41±1.29)枚<(7.95±1.76)枚]、淋巴结大小[(0.49±0.11)cm<(0.65±0.13)cm]、短长径比值[(0.69±0.09)<(0.81±0.11)]低于恶性淋巴结患者(t=10.328、4.756、4.284,P<0.05)。结论:在直肠癌的临床诊断中,应用16层螺旋CT,结合CT影像进行分析,能够准确检出淋巴结转移的发生,进而对疾病的发展情况做出判断,便于及时采取针对性的治疗措施。Objective:To investigate the application of 16 slice spiral CT in the clinical diagnosis of rectal cancer with lymph node metastasis,and to analyze the results of CT diagnosis.Methods:51 patients with rectal cancer admitted in our hospital from May 2019 to June 2022 were selected as the study objects,and 16 slice spiral CT was used for diagnosis.Combined with CT images,the occurrence and progress of lymph node metastasis were analyzed.Results:The pathological diagnosis of rectal cancer patients with lymph node metastasis showed 29 cases of benign and 22 cases of malignant lymph nodes,respectively.The CT diagnosis showed 30 cases of benign and malignant lymph nodes(2 cases were misdiagnosed as malignant)and 21 cases(1 case was misdiagnosed as benign),respectively.The sensitivity,specificity and accuracy of the diagnosis of rectal cancer lymph node metastasis were 96.55%(28/29),90.91%(20/22)and 94.12%(48/51).Combined with the CT diagnosis results,the number of lymph nodes[(3.41±1.29)<(7.95±1.76)],the size of lymph nodes[(0.49±0.11)cm<(0.65±0.13)cm],and the short length diameter ratio[(0.69±0.09)<(0.81±0.11)]in patients with benign lymph nodes were lower than those in patients with malignant lymph nodes(t=10.328,4.756,4.284,P<0.05).Conclusion:In the clinical diagnosis of rectal cancer,the application of 16 slice spiral CT combined with CT image analysis can accurately detect the occurrence of lymph node metastasis,and then make a judgment on the development of the disease,which is convenient for timely taking targeted treatment measures.
