Initial experiences and troubleshooting of Senhance robotic system: A community hospital perspective

Abstract

Purpose: The purpose of this study is to demonstrate the feasibility and safety of the Senhance robotic system in urologic surgeries. Materials and methods: Patients were included prospectively from July 2018 to December 2020. The exclusion criteria included severe cardiopulmonary diseases and previous extensive abdominal surgeries. Institutional approval and informed consent were obtained. We used the Clavien-Dindo classification system to evaluate the complications that occurred within 30 days after surgery. Common technical and mechanical events encountered were also recorded. Results: A total of 173 patients were recruited. The median age was 65 (58–74) years, and the median body mass index was 24.7 (16.5–35.6) kg/m 2 . Seventeen (9.8%) patients had previously undergone abdominal surgeries. Eighty-three (48%) cases had total extraperitoneal hernioplasty and 32 (18.5%) cases radical prostatectomy, which were the largest 2 surgeries in our study. Sixty-one (35.3%) patients received surgeries due to malignancy. The median docking time was 5 (1–35) minutes. There were 28 (16.2%) cases with grade I complications and 9 (5.2%) cases with grade II complications. Only one case of a grade IIIb complication occurred during radical prostatectomy. No grade IV complications or mortalities were noted. Robotic arm collisions and forces exceeding the limit were the most commonly encountered problems intraoperatively. Conclusion: In our initial experiences, the Senhance robotic system was feasible in oncologic and nononcologic urologic surgeries and had acceptable outcomes. The haptic feedback system is unique and requires a learning period. This system may serve as an alternative tool for robotic urologic surgeries.
