Area of Science:

  • Minimally Invasive Surgery
  • Surgical Technology
  • Gastrointestinal Surgery

Background:

  • Laparoscopic surgery often requires pneumoperitoneum for visualization.
  • Trocar insertion is a critical step with potential for injury.
  • Previous abdominal surgeries can complicate laparoscopic access.

Purpose of the Study:

  • To evaluate the safety and efficacy of the OPTIVIEW Optical Surgical Obturator for laparoscopic procedures.
  • To assess the incidence of trocar-related complications using this device.
  • To determine the utility of visually guided trocar entry without insufflation.

Main Methods:

  • A retrospective review of 1187 laparoscopic procedures using the OPTIVIEW Optical Surgical Obturator.
  • Analysis of complication rates, including trocar-related injuries and late complications.

Related Experiment Videos

  • Assessment of visualization and pneumoperitoneum achievement in diverse patient populations.

    • Main Results:

    • Successful visualization and pneumoperitoneum were achieved in all 1187 patients.
    • The overall complication rate was low at 0.3% (4/1187).
    • Trocar-related injuries included two bowel injuries and one mesenteric injury, all repaired intraoperatively. One late incisional hernia was noted.

    Conclusions:

    • The OPTIVIEW Optical Surgical Obturator facilitates safe and effective laparoscopic surgery.
    • Visually guided trocar entry without insufflation is associated with a low rate of complications.
    • The device is suitable for patients with a history of prior abdominal surgeries.
