Robotic-assisted single-incision right colectomy: early experience.
BACKGROUND
Application of laparoendoscopic single-site surgery (LESS) is increasing across surgical disciplines. In addition to the possibility of decreased postoperative pain, LESS offers better cosmesis with virtually 'scarless' surgeries, while avoiding the increased costs and complexity of natural orifice surgery. Instrument conflict minimization often requires the crossing of articulating instruments, which we believe can be more intuitively facilitated using the daVinci-S((R)) robotic system. We describe our early experience with three robotic single-incision right hemicolectomies.


METHODS
Three robotic single-incision right hemicolectomies were performed using the daVinci-S robotic system, utilizing a single 4 cm incision through or around the umbilicus. The procedure was performed using three robotic arms, a 12 mm camera and two 8 mm robotic ports. A medial to lateral approach was used and an extracorporeal resection and anastomosis was performed after undocking the robot.


RESULTS
There were no intraoperative or postoperative complications. Average operative time was 152 min. The first case was converted to non-robotic single-incision right hemicolectomy during mobilization of the ascending colon, due to uncontrollable air leakage around the ports. The second and third cases were successfully completed without air loss by purse-stringing sutures around each individual port and the use of the SILS() port, respectively.


CONCLUSIONS
Robotic-assisted single-incision right hemicolectomy can be successfully and safely performed using the daVinci-S robotic system. Several techniques may be employed to prevent the loss of pneumoperitoneum. We believe right hemicolectomy lends itself to single-site surgery because specimen extraction requires a 4 cm incision and may confer patient benefit, with decreased postoperative pain and improved cosmesis. By crossing the robotic instruments and reassigning control of the arms, the robot represents a means to help perform these procedures safely by allowing them to be performed in a more intuitive fashion.
