探讨多层螺旋CT三维重建技术在疝补片大小选择中的临床意义。

回顾性分析2015年10月至2016年12月，青海大学附属医院30例腹腔镜下腹股沟疝无张力修补术患者术中补片选择情况及影像学资料。多层螺旋CT三维重建技术诊断腹股沟疝共30例，术前应用该技术测量联合肌腱上方2 cm（横断位定点）处至上耻骨支的骨膜的距离，结合髂前上棘至耻骨结节的距离（体外测量），预判术中使用补片大小，并与术中实际应用的疝补片大小进行对比。

术前与术中2组数据关于联合肌腱上方2 cm（横断位定点）处至上耻骨支的骨膜的距离的测量的比较[（7.603±0.299）cm比（7.536±0.270）cm]，差异无统计学意义（P>0.05）。

通过应用多层螺旋CT三维重建技术，可以非常准确的在腹股沟疝修补术前判断腹股沟疝患者在该手术中所需要的适合自己腹股沟区情况的疝补片的尺寸。

To discuss the clinical significance of multi-slice spiral CT 3D reconstruction technology in the selection of size of hernia mesh.

A retrospective analysis of 30 cases of laparoscopic inguinal hernia tension-free repair in patients with patch selection and imaging data in the affiliated hospital of Qinghai university from October 2015 to December 2016. Multi-slice spiral CT 3D reconstruction technology in diagnosis of inguinal hernia in 30 cases, this technology was used to measure the distance between 2 cm above the tendon (transection point) and the periosteum of the suprapubic branch who met the surgical conditions before operation. In combination with the distance of the superior iliac superior spine to the pubis tubercle (vitro measurement), making an anticipation in the size of hernia patch of preoperative, and compared with the actual size of hernia patch which was used in the operation.

There was no significant difference in the measurement of distance data of preoperative and intraoperative between 2 cm above the tendon (transection point) and the periosteum of the suprapubic branch, [(7.603±0.299) cm to (7.536±0.270) cm, P>0.05].

Through the application of multi-slice spiral CT 3D reconstruction technology,we can accurately determine the size of hernia patch which is suitable for the inguinal hernia patients before the operation of inguinal hernia repair.
