探讨多层螺旋CT三维重建技术在切口疝术前评估的应用及临床意义。

回顾性分析2020年1至12月，首都医科大学附属北京朝阳医院西区43例住院患者影像学资料及手术资料。多层螺旋CT三维重建技术诊断切口疝共43例，术前应用该技术测量切口疝疝口横径及上下径，并与术中测量的径线进行对比。

43例患者均顺利完成切口疝补片修补术。CT测量与术中测量的宽径和上下径值比较，差异均无统计学意义[（11.64±3.60）cm比（11.28±4.01）cm，（14.06±3.79）cm比（13.37±4.36）cm，P>0.05]。CT测量的宽径值与术中测量的宽径值具有相关性（r=0.89，P<0.01）；CT测量的上下径值与术中测量的上下径值具有相关性（r=0.85，P<0.01）。

通过应用多层螺旋CT三维重建技术，可以在切口疝修补术前准确判断患者在该手术中所需要的适合自己腹壁缺损情况的疝补片的尺寸，并拟定手术计划。

To investigate the clinical significance of multi-slice spiral CT three-dimensional (3D) reconstruction in evaluation for incisional hernia before surgery.

The imaging and surgical data of 43 inpatients in the West District of Beijing Chaoyang Hospital from January 2020 to December 2020 were retrospectively analyzed. All the 43 patients were diagnosed with incisional hernia by multi-slice spiral CT 3D reconstruction. Preoperatively, the transverse and vertical diameters of incisional hernia were measured using this technique and compared with those measured during surgery.

All the 43 patients were successfully completed incisional hernia repair. No statistically significant differences were found between the preoperative and intraoperative measurements at the transverse position (P>0.05), or between the preoperative and intraoperative measurements at the vertical position (P>0.05). The results suggested no significant differences between preoperative CT measurements and intraoperative measurements. Therefore, preoperative CT evaluation was accurate and valuable.

The application of multi-slice spiral CT 3D reconstruction can accurately determine the size of the hernia patch needed for the patients during the surgery, which is suitable for their own abdominal wall defects before incisional hernia repair, and it is convenient to plan the surgery.
