title: Robotically assisted laparoscopic tubal anastomosis in a porcine model: a pilot study.
abstract: As with standard microsurgical procedures performed at laparotomy, laparoscopic tubal anastomosis requires great dexterity. Handling fine suture materials under magnification to anastomose tubal segments with lumens less than 3 mm in diameter while working with your hands at a distance from the tissue makes these fine movements even more difficult. This is exacerbated by the tremor induced by the fatigue caused by a prolonged laparoscopic procedure and the need for precise control. We conducted a pilot study to evaluate the feasibility of performing laparoscopic tubal anastomosis with robotic assistance in a live porcine model. Two anastomoses were performed on one uterine horn via each of the following techniques: laparoscopy, laparoscopy with robotic assistance, and open microsurgery. Immediate necropsy demonstrated all the anastomoses to be patent. There were no intraoperative complications. Laparoscopic tubal anastomosis was associated with surgeon fatigue and neck, shoulder, and back pain. The surgeons were more comfortable performing the procedure with robotic assistance. The device functioned well and without incident. This acute animal study suggests that robotic assistance in laparoscopic tubal anastomoses is safe and feasible. It enhances surgeons' dexterity and precision while reducing fatigue. It is promising for future use in chronic experimental studies.
