Background:
Robot-assisted transabdominal preperitoneal inguinal hernia repair (rTAPP) has been established with various robotic platforms. The Dexter robotic system is an open platform consisting of a sterile surgeon's console, two robotic instrument arms, and one robotic endoscope arm. This study aimed to confirm the perioperative and early postoperative safety and clinical performance of the Dexter system in patients undergoing primary transperitoneal inguinal hernia repair.
Methods:
The primary objectives of this multicenter study conducted at three centers in France, Germany, and Switzerland were to document the successful completion of rTAPP procedures and the occurrence of serious adverse events (Clavien-Dindo grades III-V), device-related events up to 30 days post-surgery. The procedures were performed by three surgeons with varying levels of experience in robotic systems.
Results:
50 patients with a median age of 62.5 years (IQR 51.0-72.0) and BMI of 25.1 kg/cm2 (IQR 23.5-28.7), respectively, underwent inguinal hernia repair (33 unilateral, 17 bilateral). All surgeries were successfully completed using three standard laparoscopy trocars. There were no conversions to open surgery, intraoperative complications or device deficiencies. The median skin-to-skin operative time was 50 min (IQR 45-60) for unilateral hernias and 96 min (IQR 84-105) for bilateral hernias. The median console time was 30 min (IQR 26-41) for unilateral and 66 min (IQR 60-77) for bilateral hernias. Twenty-six patients were discharged on the day of surgery, and 22 on postoperative day 1.
Conclusion:
This study confirmed the use of the Dexter system in rTAPP was feasible and safe in multicenter cohorts, with operative times consistent with the literature on other robotic platforms. Our data demonstrated the accessibility of this new robotic approach, even when adopted by surgeons new to robotics. The Dexter system emerged as a valuable device in the hernia repair toolkit for both experienced robotic surgeons and those new to the field.
