Robotic versus open lateral abdominal hernia repair: a multicenter propensity score matched analysis of perioperative and 1-year outcomes.

ABSTRACT

PURPOSE: Lateral abdominal hernias are inherently challenging surgical entities. As such, there has been an increase in the adoption of robotic platforms to approach these challenging hernias. Our study aims to assess and compare outcomes between open (oLAHR) and robotic (rLAHR) lateral abdominal hernia repair using a national hernia-specific database. METHODS: A retrospective review of prospectively collected data from the Abdominal Core Health Quality Collaborative was performed to include all adult patients who underwent elective lateral hernia repair. A propensity score match analysis was conducted, and univariate analyses were conducted to compare these two surgical modalities across perioperative timeframes. RESULTS: The database identified 2569 patients. Our analysis matched 665 patients to either the open or robotic groups. The median length of stay, surgical site occurrences (SSO), and surgical site occurrences requiring procedural interventions (SSOPI) were higher in the oLAHR versus the rLAHR group. Overall, oLAHR had a significantly higher rate of having any post-operative complications or any SSO/SSOPI. There was no difference in quality-of-life measures between groups at 30 days and 1 year. CONCLUSION: Robotic abdominal hernia repair is a safe alternative compared to the open repair of lateral abdominal hernias with better perioperative outcomes. Despite having a longer operative time, the robotic approach can offer a significantly shorter length of stay and an overall lower rate of complications. Ultimately, there is no difference in the quality-of-life measures both at 30 days and 1 year between the open and robotic approaches.
