Area of Science:

  • Minimally Invasive Surgery
  • Surgical Technology
  • Abdominal Surgery

Background:

  • Endoscopic procedures require specialized tools for organ manipulation.
  • Challenges include maintaining pneumoperitoneum and preventing contamination during extraction.
  • Tissue approximation and reconstruction can be technically demanding.

Purpose of the Study:

  • To introduce the extracorporeal pneumoperitoneum access bubble (EPAB) as a novel device.
  • To evaluate the EPAB's utility in facilitating organ extraction and tissue approximation during endoscopic surgery.
  • To assess the impact of EPAB on wound dilation and contamination prevention.

Main Methods:

  • Development and deployment of the EPAB device.
  • Surgical procedures involving large organ extraction and tissue approximation.

Related Experiment Videos

  • Measurement of exit wound dilation and assessment of contamination control.
  • Evaluation of the operating version for hand/instrument introduction without pneumoperitoneum deflation.

    • Main Results:

    • EPAB creates a transparent extension of the pneumoperitoneum.
    • Average exit wound dilation of 48.5% without regard to location.
    • Elimination of contamination and tumor seedling implantation risks.
    • Facilitation of organ extraction and reduction in technical difficulty for reconstruction.

    Conclusions:

    • The EPAB is an effective tool for endoscopic surgery, improving organ extraction and preventing contamination.
    • It simplifies complex surgical tasks like dissection and reconstruction.
    • EPAB technology offers significant advantages in minimally invasive abdominal procedures.
