Background The daVinci Single-Port (SP) robot is a new robotic platform designed to overcome the challenges of Single-Incision Laparoscopic Surgery. The objective of this study is to demonstrate the feasibility and technical aspects of SP robotic (SP r) left colectomy using the SP platform. Methods Under Institutional Review Board approval and registration on ClinicalTrials.gov, we performed SP rLeft colectomy using the daVinci SP surgical system on four patients. The primary end-point of this study was to report and describe the technical feasibility to perform SP rLeft colectomy. The secondary end-points included perioperative metrics and outcomes. Results Four patients underwent successful SP rLeft colectomy for diverticulitis through a single incision (average size: 4.4 cm) without intraoperative complications or conversions. The robot was docked 2.7 times on average (range 2–4). The average docking time was 8.4 min (range: 3–33 min). The mean estimated blood loss was 91 mL (range: 20–250 mL). There were no morbidities or mortalities. Patients were discharged on POD 2 and 3. Conclusion We demonstrated in this initial clinical series the SP rLeft colectomy to be feasible and safe to perform in select patients. The SP robot’s single-arm design and flexible instruments have shown to provide excellent visualization and retraction with minimal collisions. We predict that the SP robot will be widely utilized in the field of colorectal surgery as it becomes available to colorectal surgeons. Further experience and larger studies are needed to define the advantages and identify the problems with the SP rLeft colectomy.
