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.
