Abstract Objective The aim of this study was to provide an interim safety analysis of the first 30 surgical procedures performed using the Versius Surgical System. Background Robot-assisted laparoscopy has been developed to overcome some of the important limitations of conventional laparoscopy. The new system is currently undergoing a first-in-human prospective clinical trial to confirm the safety and effectiveness of the device when performing minimal access surgery (MAS). Methods Procedures were performed using Versius by a lead surgeon supported by an operating room (OR) team. Male or female patients aged between 18 and 65 years old and requiring elective minor or intermediate gynaecological or general surgical procedures were enrolled. The primary endpoint was the rate of unplanned conversion of procedures to other MAS or open surgery. Results The procedures included nine cholecystectomies, six robot-assisted total laparoscopic hysterectomies, four appendectomies, five diagnostic laparoscopy cases, two oophorectomies, two fallopian tube recanalisation procedures, an ovarian cystectomy and a salpingo-oophorectomy procedure. All procedures were completed successfully without the need for conversion to MAS or open surgery. No patient returned to the OR within 24 h of surgery and readmittance rate at 30 and 90 days post-surgery was 1/30 (3.3%) and 2/30 (6.7%), respectively. Conclusions This first-in-human interim safety analysis demonstrates that the Versius Surgical System is safe and can be used to successfully perform minor or intermediate gynaecological and general surgery procedures. The cases presented here provide evidence that the Versius clinical trial can continue to extend recruitment and begin to include major procedures, in alignment with the IDEAL-D Framework Stage 2b: Exploration.
