Abstract From December 2005 to December 2009, we performed 150 laparoscopic colorectal procedures. Based on this experience, we started offering robot-assisted colorectal surgery from December 2009. This study is a prospective evaluation of consecutive patients in order to study the technical feasibility and oncological outcome of robot-assisted low anterior resection. This investigation was conducted at a single minimal access surgery institute. Between December 2009 and December 2011, 53 consecutive patients with rectal adenocarcinoma underwent a robot-assisted low anterior resection (LAR) or ultralow anterior resection (ULAR) with total mesorectal excision (TME), using the standard da Vinci ‘S’ model. Patient demographics, mean operative time, mean postoperative hospital stay, blood loss, days to first flatus, resumption of oral feeds, urinary incontinence, and sexual dysfunction were studied. Surgical and pathological outcomes such as quality of TME, free circumferential margins, and number of lymph nodes dissected were also evaluated. Robot
docking and undocking times were noted. Of the 53 patients, 41 were men and 12 were women. Their mean age was 66.7 years (range 37–90 years). The ASA grades were distributed as follows: ASA I 15 (28.3 %), ASA II 25 (47.16 %), ASA III 12 (22.64 %), ASA IV 1 (1.88 %). The mean operative time was 180 min (150–230 min) and the mean blood loss was 101.6 ml (50–300 ml). The robot docking time was 10 min (15–25 min) and the undocking time was 5 min (3–10 min). The mean hospital stay was 8 days (7–15 days). None of the patients was converted to either laparoscopic or open procedure. The longitudinal and circumferential margins were negative in all patients. Histopathological reports of 45 patients showed complete TME while 8 patients showed nearly complete TME. No repositioning of the robot was needed for splenic flexure mobilization, thus decreasing the operative time. Along with TME, even the splenic flexure mobilization was achieved through the same robotic ports without undocking the robot. Robot-assisted LAR and ULAR is technically feasible, and a complete TME is possible.
