Introduction Robotic-assisted groin hernia repair has rapidly expanded across surgical practice in the United States, driven by increasing adoption of minimally invasive techniques and perceived technical advantages such as enhanced visualization and improved surgeon ergonomics. Despite this growth, robust population-level evidence comparing long-term outcomes of robotic, laparoscopic and open approaches remains limited.
Introduction
Robotic-assisted groin hernia repair has rapidly expanded across surgical practice in the United States, driven by increasing adoption of minimally invasive techniques and perceived technical advantages such as enhanced visualization and improved surgeon ergonomics. Despite this growth, robust population-level evidence comparing long-term outcomes of robotic, laparoscopic and open approaches remains limited.
Problem Statement
Although robotic surgery is increasingly used for groin hernia repair, it remains unclear whether this technology improves long-term durability compared with established laparoscopic and open techniques. Given the substantial costs and rapid dissemination of robotic platforms, understanding whether robotic repair meaningfully reduces recurrence is essential for evaluating its true clinical value.
Summary
This large Medicare-based cohort study found that robotic-assisted groin hernia repair was associated with slightly higher long-term operative recurrence rates compared with laparoscopic and open approaches, without demonstrating a clinically meaningful advantage in repair durability. Over five years of follow-up, recurrence rates remained low across all surgical techniques, but laparoscopic repair consistently showed the lowest recurrence risk, while robotic-assisted repair demonstrated the highest cumulative recurrence incidence. Importantly, these findings remained stable across multiple sensitivity analyses, including elective versus emergent repairs, unilateral versus bilateral procedures and varying levels of surgeon robotic utilization. The study highlights the rapid expansion of robotic-assisted hernia surgery despite limited evidence of superior long-term outcomes and raises important questions regarding technology adoption driven more by market forces and procedural diffusion than by demonstrable clinical benefit. The authors emphasize that recurrence rates alone may not fully capture the value of robotic surgery and suggest that future evaluation should incorporate broader outcomes such as recovery, conversion rates, patient experience and healthcare utilization. Overall, the findings challenge assumptions that robotic repair offers superior long-term effectiveness for groin hernia surgery and reinforce the need for evidence-based adoption of surgical innovation.
