Abstract:
Objective To make an initial attempt to use robotic single-site surgery for laparoscopic partial nephrectomy and ureteropelvic angioplasty in pigs, so as to assess the feasibility and ergonomics of the robotic single-site surgery in laparoscopic urological reconstruction surgery and to summarize the manipulation experience. Methods Partial nephrectomy: at a lateral position, a 4 cm incision was made at the level of hilum on the lateral border of the rectus muscle, and the subcutaneous tissue layer was dissected bluntly with the Kelly clamp. After pneumoperitoneum was established by the veress needle, four trocars were introduced in the shape of diamond, including two 8 mm robotic trocars on the left and right rides and two 10 mm surgiquest trocars on the upper and lower rides. After the robotic tower was docked, the procedure of nephrectomy was performed routinely. And the renal defect was closed by a horizontal mattress suture with "sliding-clip technique". Pyeloplasty: all trocars were removed and a 4 cm long incision was made; the novel suriquest robotic port was introduced into the abdominal cavity. Two 8 mm robotic metal trocars were introduced from two sides of the surgiquest port in the way of "1 + 1". After the robotic arm was docked, the pyeloplasty was performed. Results Partial nephrectomy were successfully performed in two cases, with the time for establishing access bring 5 min and 8 min, time for docking the robotic system bring 11 min and 9 min, time for operation bring 55 min and 42 min, and time of warm ischemia bring 23 min and 18 min, and with the blood loss bring 50 ml and 20 ml. Pyeloplasty were successfully performed in two cases, with the time for establishing access bring 17 min and 12 min, time for docking the robotic system bring 5 min and 4 min, and time of operation bring 32 min and 25 min, andwith no blood loss. Conclusion After proper setup of trocars, the roboic single-site operation under laparoscope can complete the complex urological reconstructive surgery. And the novel surgiquest port can obtain more ideal ergonomics outcomes.
