This retrospective study investigates if robotic assisted groin hernia repair in patients who previously underwent abdominal prostatectomy has an equal or more favorable clinical outcome, compared to open repair in those patients.

In the personal practice of the investigators, there has been a decrease in open groin hernia repair from 17% to 6% since the introduction of robotic assisted surgery. This reflects a change in indication for complex hernias from an open to a minimal invasive approach. One of the typical indications for open approach before adopting the robotic platform were groin hernias after previous abdominal prostatectomy. Since prostatectomy results in scarring of the retropubic area where we need to dissect during MIS groin hernia repair, an open anterior approach is often suggested. With the enhanced view and instrument dexterity of the robotic platform, the investigators have now changed to a minimal invasive approach in these patients.

Therefore, this study will evaluate the clinical outcome after robotic assisted repair of groin hernias in patients who previously underwent an abdominal prostatectomy in comparison to open groin hernia repair.

Inclusion Criteria:

• Adult patients
• Underwent uni-or bilateral groin hernia repair in the period March 2015 - March 2020
• Groin hernia repair via robotic assisted laparoscopy or open surgery
• History of abdominal prostatectomy before the groin hernia repair

Exclusion Criteria:

• Age below 18
• Groin hernia repair via conventional laparoscopy
• Groin hernia repair via open surgery other than Liechtenstein method
• Groin hernia repair without mesh placement

Patients who underwent robotic assisted or open inguinal hernia repair in the period March 2015 - March 2020 and previously underwent an abdominal prostatectomy.
