结肠CT三维重建技术在结肠癌术前诊断中的应用价值

Application Value of Colon CT Three dimensional Reconstruction in Preoperative Diagnosis of Colon Cancer

目的探究结肠CT三维重建技术在结肠癌术前诊断中的应用价值。方法收集2018年1月至2019年12月来我院就诊的拟行左半结肠癌根治术患者66例,患者术前行CT检测,观察肿瘤分期、定位,观察肠系膜下动脉解剖结构及血供,将术前肿瘤分期及定位与术后结果比较。结果66例结肠癌患者中,与病理检测结果比较,CT对T分期诊断正确59例(87.88%),对N分期诊断正确43例(65.15%),对M分期诊断正确66例(100%);与手术探查结果比较,CT三维重建定位肿瘤的准确率为93.94%;术前CT三维重建可显示肠系膜下动脉解剖结构及血供位置。结论术前结肠CT三维重建技术能够明确结肠癌患者的肿瘤分期、位置,清楚显示肠系膜下的动脉解剖结构及血供关系,有利于指导临床手术,提高手术效率及安全性。

Objective To explore the application value of colon CT three-dimensional reconstruction in preoperative diagnosis of colon cancer.Methods A total of 66 patients who underwent elective radical resection of left colon cancer in the hospital from January 2018 to December 2019 were collected.All underwent preoperative CT examination.The staging and locating of tumors,anatomical structure of inferior mesenteric artery(IMA),and blood supply were observed.The preoperative staging and locating of tumors were compared with the postoperative results.Results Of the 66 colon cancer patients,the comparison with pathological examination results showed that there were 59 cases(87.88%)at stage T,43 cases(65.15%)at N and 66 cases(100%)at M correctly diagnosed by CT.The comparison with surgical exploration results showed that accuracy of CT three-dimensional reconstruction for locating tumors was 93.94%.The preoperative CT three-dimensional reconstruction could display anatomical structure of IMA and blood supply sites.Conclusion The preoperative colon CT three-dimensional reconstruction can determine tumor staging and sites of patients with colon cancer,clearly show anatomical structure of IMA and blood supply relationship,which is beneficial to guide clinical operation,improve surgical efficiency and safety.
