To investigate the influence factors of testicular artery perfusion after laparoscopic totally extraperitoneal inguinal prosthetic (TEP).

A total of forty-three male patients with primary unilateral inguinal hernia who underwent TEP in Jiangmen Central Hospital from September 2013 to June 2016 were enrolled in this study. Pre- and post-operative testicular artery perfusion, peak systolic velocity (PSV) and end diastolic velocity (EDV), were detected and compared in each group including age, body mass index (BMI), disease duration and operation time.

Repeated measurement ANOVA showed that testicular artery perfusion after TEP had significantly differences in every measurement time in group age and operative duration, and there was also interaction between time effect and group effects. Postoperative testicular artery perfusion recovering to preoperative condition was related to age and operative duration significantly, but not to BMI and disease duration. Besides, multivariate Logistics regression analysis showed that age and operative duration were independent risk factors for the recovery of testicular artery perfusion after TEP operation (OR=1.102, 1.102, P=0.005, 0.006, 95%CI: 1.030-1.180, 1.028-1.182).

After laparoscopic totally extraperitoneal inguinal prosthetic, testicular artery perfusion of patients with older age or undergoing longer operative duration need more time to recover to preoperative condition.
