Introduction Preperitoneally placed mesh for inguinal hernia repair may require removal to address hernia recurrence, mesh reaction, meshoma, or other chronic pain. These are best approached either laparoscopically or robotically, but there is no consensus on which is the best approach for mesh removal nor are there any studies to evaluate and compare their outcomes. Methods All patients who underwent inguinal mesh removal via laparoscopic and robotic approaches from 2011 to 2020 were analyzed. Data regarding demographics, preoperative, intraoperative, and postoperative outcomes were collected. Results Over 9 years, 62 patients underwent 24 laparoscopic and 50 robotic operations. Laparoscopic cases had a shorter operative time by a mean of 55 min ( p  = 0.02). There were no differences in intraoperative complications or postoperative outcomes between the two groups. Patients in both groups showed significant improvement after mesh removal ( p  = 0.02, p  < 0.01) within 2 weeks postoperatively and at long-term follow up ( p  < 0.01, p  < 0.01). Conclusion It is our experience that both laparoscopic and robotic approaches are viable options for removal of retroperitoneally placed inguinal mesh. Operative time with the laparoscopic approach was significantly shorter than the robotic approach. Patients on average had significant reduction in their preoperative pain, regardless of the approach. Minimally invasive mesh removal is a technically challenging operation, with risk of vascular and nerve injuries regardless of the approach. These findings demonstrate that both modalities are safe and effective with experienced surgeons.
