Abstract
Abstract Background Robot-assisted transabdominal preperitoneal inguinal hernia repair (rTAPP) is established as safe and feasible with various robotic platforms. The Dexter robotic system is an open platform with a sterile surgeon’s console, two robotic instrument arms, and one robotic endoscope arm. Aims We conducted a prospective multicentre study (ClinicalTrials.gov NCT05873582) to assess the safety and performance of this new robotic platform. Methods Three centres in France, Germany, and Switzerland participated. The primary objectives of the study were to document the successful completion of the rTAPP procedures and to collect data on the occurrence of adverse events and device-related events perioperatively and up to 30 days post-surgery. The procedures were performed by three surgeons with varying levels of experience in robotic systems, including novice, intermediate and expert. Results Fifty patients were operated for inguinal hernia repair (33 unilateral, 17 bilateral). The mean age and BMI of the patients were 60 years (±15) and 25.7 kg/cm2 (±3.3), respectively. All surgeries were successfully completed as planned using three standard laparoscopy trocars sized 10/12mm. Each procedure was performed with robotic assistance, and there were no conversions to open surgery. No intra-operative complications, device deficiency, or adverse events of Clavien-Dindo Grade III to V occurred. The mean skin-to-skin operative time was 55 min (±14) for unilateral hernia repair and 95 min (±22) for bilateral hernia repair. The mean robotic console time was 34 min (±12) for unilateral hernia and 68 min (±21) for bilateral hernia repairs. The patients were discharged within 1day (± 1 day) after surgery. Conclusion Our rTAPP experience with the Dexter system confirms feasibility, safety, and comparable operative times to other robotic platforms. This study demonstrates the practicality and safety of the robotic techniques, positioning the Dexter system as a valuable tool in hernia repair.
