Objective:
To investigate the influence of single-port laparoscopic percutaneous extraperitoneal closure (LPEC) on the orientation of the vas deferens and the volume and perfusion of the testis in pediatric patients undergoing inguinal hernia repair.
Methods:
A total of 92 consecutively enrolled boys diagnosed with unilateral inguinal hernia underwent single-port LPEC between June 2013 and June 2014. The orientation of the vas deferens and the testicular volume and perfusion of the patients were ultrasonographically assessed preoperatively and at 1 and 6 months after surgery.
Results:
All the surgical procedures were performed successfully without conversion or serious perioperative complications. Ultrasonography showed no angulation or distortion of the vas deferens on the surgical side during a six-month follow-up period. Similarly, no obvious changes were observed in the testicular volume or perfusion.
Conclusions:
Single-port LPEC is safe and effective in the treatment of pediatric inguinal hernia and does not affect the orientation of the vas deferens or testicular volume and perfusion.

Background and Environment Affect Phenotype
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...
