title: Laparoscopic versus robotic right colectomy: a single surgeon's experience.
abstract: There is increased interest in robotic techniques for colon resection, but the role of robotics in colorectal surgery has not yet been defined. The purpose of this study was to compare our recent experience with robotic right colectomy to that with laparoscopic right colectomy. From November 2008 to June 2011, a total of 47 consecutive patients underwent elective, right colectomy: 25 laparoscopic right colectomies (LRC) and 22 robotic right colectomies (RRC). All procedures in this study were performed by a single, board-certified colon and rectal surgeon (H.J.L.). Main outcomes recorded included conversion rate, operative time (OT), estimated blood loss (EBL), length of extraction sites, length of stay (LOS), and complications. Data studied were prospectively recorded in a database and were retrospectively reviewed. Mean OT for LRC was 107 ± 36.7 min (median 98, range 48-207) and for RRC was 189.1 ± 38.1 min (median 185, range 123-288, P < 0.001). Mean total operating room time (TORT) for LRC was 158.6 ± 38.1 min (median 149, range 104-274) and for RRC was 258.3 ± 40.9 (median 251, range 182-372, P < 0.001). The tendency lines for both OT and TORT decreased over time for RRC. EBL for LRC was 70.2 ± 52.9 ml (median 50, range 10-200) and for RRC was 60.8 ± 71.3 ml (median 40, range 10-300, P = 0.037). The mean extraction site length for the laparoscopic group was 5.3 ± 1.3 cm (median 5, range 4-11) and for the robotic group was 4.6 ± 0.7 cm (median 4.5, range 3.5-6, p = 0.008). LOS was similar for both groups, as were complications. No cases were converted to open. No leaks occurred and there was no 30-day mortality. RRC is safe and feasible, with similar outcomes to LRC. Operative times were longer for RRC; however, they compare favorably with times for LRC published in the literature. Extraction site length and EBL were less for RRC. However, further study is necessary to demonstrate the clinical relevance of these findings. We are optimistic that OT and TORT will continue to improve.
