Area of Science:

  • Surgical innovation
  • Medical device engineering
  • Hernia repair techniques

Background:

  • The PROLENE Hernia System (PHS) is a standard device for anterior preperitoneal inguinal hernia repair.
  • Challenges exist in fully expanding and securely positioning the underlay patch of the PHS.

Purpose of the Study:

  • To introduce and evaluate a modified PHS device with a novel "deploying pocket" for enhanced underlay graft expansion.
  • To assess the efficacy and security of this modified device in preperitoneal inguinal hernia repair.

Main Methods:

  • A modified PHS device was designed with a flat, perimeter-reinforced "deploying pocket" within the underlay graft.
  • A specific surgical technique utilizing an angled metal pusher was developed for intrapocket manipulation and graft deployment.

  • The modified device and technique were employed for inguinal/femoral hernia repair.

    • Main Results:

    • The "deploying pocket" facilitates complete expansion and secure placement of the underlay graft in the preperitoneal space.
    • The graft effectively covers the entire myopectineal orifice, crucial for hernia repair.
    • Encouraging clinical results demonstrate the effectiveness of this modified approach.

    Conclusions:

    • The modified PHS device with a "deploying pocket" and specialized surgical technique offers an improved method for inguinal/femoral hernia repair.
    • This innovative approach ensures optimal graft deployment and secure fixation, leading to effective hernia treatment.
