AIM: To compare robotic and three-dimensional (3D) laparoscopic colectomy based on the literature and our preliminary experience.
METHODS: This retrospective observational study compared operative measures and postoperative outcomes between laparoscopic 3D and robotic colectomy for cancer. From September 2013 to September 2014, 24 robotic colectomies and 23 3D laparoscopic colectomy were performed at our Department. Data were analyzed and reported both by approach and by colectomy side. Robotic left colectomy (RL) vs laparoscopic 3D left colectomy (LL 3D) and Robotic right colectomy (RR) vs laparoscopic 3D (LR 3D). Rectal cancer procedures were not included.
RESULTS: There were 18 RR and 11 LR 3D, 6 RL and 12 LL 3D. As regards LR 3D, extracorporeal anastomosis (EA) was performed in 7 patients and intracorporeal anastomosis (IA) in 4; the RR group included 14 IA and 4 EA. There was no mortality. Median operative time was higher for the robotic group while conversion rate (12.5% vs 13%) and lymph nodes removed (14 vs 13) were similar for both. First flatus time was 1 d for RR and 2 d the other patient groups. Oral intake was resumed in 1 d by LR and in 2 d by the other patients (P = 0.012). Overall cost was €4950 and €1950 for RL and LL 3D, and €4450 and €1450 for RR and LR 3D, respectively.
CONCLUSION: There were no differences between RR and LR 3D, except that IA was easier with RR, and probably contributed with the learning curve to the longer operative time recorded. Both techniques offer similar advantages for the patient with significantly different costs. In left colectomies robotic colectomy provided better outcomes, especially in resections approaching the rectum.
Core tip: Three-dimensional (3D) vision systems (Robotic and 3D laparoscopy) have been applied recently in the field of general colorectal surgery. They have brought a lot of benefits not only for the surgeon but also for the patient. However the robotic technique is very expensive, and no study has been published comparing these two techniques. Here, we compared robotic colorectal surgery to 3D laparoscopic with respect to short term outcomes and costs.
