Abstract

Abstract Purpose Robotic assisted surgery is an alternative, fast evolving technique for performing colorectal surgery. The primary aim of this single center analysis is to compare elective laparoscopic and robotic sigmoid colectomies for diverticular disease on the extent of operative trauma and the costs. Methods Retrospective analysis from our prospective clinical database to identify all consecutive patients aged ≥ 18 years who underwent elective minimally invasive left sided colectomy for diverticular disease from January 2016 until December 2020 at our tertiary referral institution. Results In total, 83 patients (31 female and 52 male) with sigmoid diverticulitis underwent elective minimally invasive sigmoid colectomy, of which 42 underwent conventional laparoscopic surgery (LS) and 41 robotic assisted surgery (RS). The mean C-reactive protein difference between the preoperative and postoperative value was significantly lower in the robotic assisted group (4,03 mg/dL) than in the laparoscopic group (7.32 mg/dL) (p = 0.030). Similarly, the robotic´s hemoglobin difference was significantly lower (p = 0.039). The first postoperative bowel movement in the LS group occurred after a mean of 2.19 days, later than after a mean of 1.63 days in the RS group (p = 0.011). An overview of overall charge revealed significantly lower total costs per operation and postoperative hospital stay for the robotic approach, 6058 € vs. 6142 € (p = 0,014) not including the acquisition and maintenance costs for both systems. Conclusion Robotic colon resection for diverticular disease is cost-effective and delivers reduced intraoperative trauma with significantly lower postoperative C-reactive protein and hemoglobin drift compared to conventional laparoscopy.
