    Laparoscopic techniques for inguinal hernia repair offer cosmetic benefits and allow inspection of the contralateral internal inguinal ring.

    A systematic review indicated a 38.5% detection rate of contralateral patent processus vaginalis (CPPV) in children undergoing laparoscopic repair.

  • 3

    Younger age and female sex have been identified as independent risk factors for CPPV in children with unilateral inguinal hernia or hydrocele.

  • 4

    The study analyzed over 1,000 children to identify preoperative predictors of CPPV and evaluate sex-specific risk factors.

  • 5

    Prophylactic repair of CPPV can be performed during laparoscopic surgery without additional skin incisions when identified intraoperatively.
