Single-Incision Robotic Colectomy (SIRC) case series: initial experience at a single center.
BACKGROUND: Laparoscopic colectomy has been associated with favorable outcomes when compared to open colectomy. Single-Incision Robotic Colectomy (SIRC) is a novel procedure hypothesized to improve upon conventional three-port laparoscopic colectomy. We hereby present and analyze our institution's initial experience with SIRC. METHODS: We performed a retrospective review of 59 patients who underwent SIRC between May 2010 and September 2013, attempting to identify factors associated with conversion rate and postoperative complication rate. RESULTS: Our study included 34 males (57.6%) and 25 females (42.4%). The mean age was 60.3 years (range 29-92 years), and the mean BMI was 26.6 kg/m(2) (range 14.9-39.7 kg/m(2)). We identified 31 right hemicolectomies (53.4%), 20 sigmoid colectomies (34.5%), 5 left hemicolectomies (1.7%), 2 low anterior resections (3.5%), and 1 total colectomy (1.7%). The overall median operative time was 188 min with an interquartile range of 79 min. Surgical indications included diverticulitis (n = 23, 39.0%), benign colonic mass (n = 18, 30.5%), colon cancer (n = 16, 27.1%), familial adenomatous polyposis (n = 1, 1.7%), and Crohn's disease (n = 1, 1.7%). There were four conversions to open procedure (6.8%), three conversions to multiport robotic procedure (5.1%), and one conversion to single-port laparoscopic procedure (1.7%). Reasons for conversions include difficulty mobilizing the colon and robotic equipment malfunction. Conversions were associated with both higher complication rates (62.5 vs 25.5%, p = 0.035) and longer LOS (7.4 vs 4.0 days, p = 0.0003). Postoperative complications occurred in 16 of the 59 cases (27.1%). Higher BMI was the only significant risk factor for postoperative complications. The overall median LOS was 4 ± 2 days, while the median estimated blood loss was 100 ± 90 ml. CONCLUSIONS: Our experience has shown that SIRC can be a safe and feasible procedure for both benign and malignant disease. Patient selection is the key to improving surgical outcomes in SIRC.
