Surgeons can perform open surgery using only video displays, though it takes longer than direct vision. This study confirms the technical feasibility of videoscopic visualization for open surgical procedures.

Area of Science:

  • Minimally invasive surgery
  • Surgical visualization techniques
  • Robotic surgery

Background:

  • Minimally invasive surgery is the future of surgical care.
  • Previous research developed a method for open surgery viewing using a rigid endoscope, robotic arm (AESOP), and stabilizing fulcrum (Alpha port).

Purpose of the Study:

  • To investigate the technical feasibility, advantages, and disadvantages of using only video images for open surgery instead of direct vision.
  • To assess the viability of videoscopic visualization in surgical procedures.

Main Methods:

  • Two surgeons with intestinal anastomosis experience performed the task.
  • Porcine intestine anastomosis was performed using two-layer suturing with digital viewing.
  • Forty videoscopic anastomoses were compared to 10 control anastomoses using direct vision.

Main Results:

  • All videoscopic anastomoses were accurate, well-coapted, patent, and leak-free.
  • Task performance time was approximately twice as long with videoscopic vision compared to direct vision (p < 0.05).

Conclusions:

  • Open surgery can be technically performed with visualization limited to video displays.
  • Videoscopic visualization is a feasible alternative for open surgical procedures, despite increased task time.
