Summary

Robot-assisted laparoscopic intestinal anastomosis is technically feasible and safe in a pig model. This advanced surgical technique demonstrated comparable mechanical integrity to traditional methods, showing promise for refined dissection and suturing.

Area of Science:

  • Minimally Invasive Surgery
  • Surgical Robotics

Background:

  • Robotic telemanipulation systems enhance surgeon dexterity and visualization in videoscopic surgery.
  • These systems facilitate refined dissection, suturing, and knot tying during complex procedures.

Purpose of the Study:

  • To demonstrate the technical feasibility of performing a safe and efficient robot-assisted handsewn laparoscopic intestinal anastomosis.
  • To evaluate this technique in a porcine model.

Main Methods:

  • Thirty intestinal anastomoses were performed in pigs: 20 robot-assisted laparoscopic (da Vinci system) and 10 open laparotomy (control).
  • Operative time, anastomosis time, and complications were recorded.
  • Mechanical integrity (passage, circumference, stitches, bursting pressure) and postoperative outcomes were assessed.

Main Results:

  • All robot-assisted procedures were completed laparoscopically; one perioperative intestinal perforation occurred.
  • Median procedure time was 77 minutes; anastomosis time was longer in the robot-assisted group (25 min) vs. controls (10 min).
  • One postoperative ileus occurred due to trocar-port herniation; all anastomoses were mechanically intact and comparable to controls.

Conclusions:

  • Robot-assisted laparoscopic intestinal anastomosis is technically feasible, safe, and efficient in a porcine model.
  • The procedure requires a reasonable operative time and yields mechanically sound anastomoses.
  • This study supports the potential of robotic systems for advanced laparoscopic gastrointestinal surgery.
