Laparoscopic TEP repair of inguinal hernia does not alter testicular perfusion

The effect of laparoscopic TEP repair on testicular perfusion is unclear. The procedure entails dissection of testicular blood vessels off the hernial sac and incorporation of a prosthetic mesh. This carries at minimum, a theoretical risk of compromise in testicular blood supply, which in turn may affect fertility. Our study aims to establish if any alteration in testicular perfusion occurs in very early (24 h), early (1 week) or late postoperative period (3 months) after laparoscopic TEP repair in the Indian population.
In our prospective trial, 20 patients underwent unilateral and 8 underwent bilateral laparoscopic TEP hernia repairs using standard technique by experienced surgeons. Flow parameters of testicular, capsular and intratesticular artery were noted using color Doppler ultrasound preoperatively and postoperatively and the postoperative resistive indexes of operated side (n = 36) were compared with preoperative values. Additionally, for unilateral repairs, flow parameters on operated side were compared with the non-operated side.
No statistically significant difference was noticed in the resistive index of the arteries upon comparing these postoperative with preoperative values. For unilateral repairs, the flow parameters of the operated side were comparable with that of non-operated side (i.e. p > 0.05).
Laparoscopic TEP performed by experienced surgeons does not alter testicular flow dynamics in early or late postoperative period.
