A robotic retromuscular ventral hernia repair involves a similar separation of the layers of the abdominal wall, similar mesh placement, and similar closure of the hernia defect. The surgical robot is a tool that allows your surgeon to place long, narrow instruments through small incisions in order to perform surgery from the inside of your abdomen. Rather than one longer incision in the middle of your abdomen, four to six small incisions, about 1 inch, are made along the outer part of your abdomen between the rib cage and hip.

Surgical site occurrence is defined as all wound complications that occur after a surgical procedure but are not surgical site infections.

Patient reported outcomes via the Hernia related quality of life score. The survey contains 12 statements about the patients abdominal wall and asks the patient to rate how strongly the disagree (1) or agree (6) with the statements on a scale 1-6. The score is calculated with the following formula: (120-[(20/12)*(sum of response on all 12 questions)]).The highest possible number, meaning the abdominal wall does not affect the patient, is 100, and the lowest, meaning the abdominal wall greatly affects the patient's quality of life, is a 0.

Patient is asked 3 different questions all in relation to their pain in the past 7 days: how intense was it as its worst, on average, and right now. They then rank their pain for each question on a scale of 1 - 5. 1 meaning no pain and 5 very severe pain. The pain scores were then averaged and used for this analysis.

Patients are asked 3 yes or no questions about their hernia operation: do you feel your hernia has come back, do you feel or see a bulge, and do you have physical pain or symptoms at the site.

The ventral hernia recurrence inventory asked patients if they have had any additional surgery since the hernia operation. If they answer yes, they choose if the surgery was for a hernia or another reason. The answers from 1 year follow up and 2 year follow up to the last question were combined for this analysis. Composite recurrence was then determined by excluding patients with negative CT scan or physical exam but had answered the ventral hernia recurrence inventory indication the hernia recurrence.

Robotic surgeries converted to open surgeries.

ASA I: A person in good health. ASA II: A mild but well-managed or treated condition. ASA III: A serious condition that has an impact on a person's overall health. ASA IV: A severe condition that's life-threatening. ASA V: A life-threatening condition that needs immediate surgery to increase survival odds.

ASA VI: A deceased person who is an organ donor.

Participants can be counted more than once in the incisional and recurrent hernia categories.

34 patients in the open arm received a posterior rectus sheath release only. 32 patients in the robotic arm received a posterior rectus sheath release only. 14 patients in the robotic arm and 10 patients in the open received a transversus abdominis release.

Open VHR

Surgical site occurrence (SSO) is defined as all wound complications that occur after a surgical procedure but are not surgical site infections.

After screening, 101 patients were consented. One patient withdrew from the study prior to surgery, leaving 100 patients randomized for inclusion. A total of 7 patients were randomized but never went through with surgery (5 randomized to open, 2 randomized to robotic repair). Two patients in the robotic arm and one in the open arm did not complete 30-day follow-up and were excluded, leaving 46 rRMVHR and 44 RMVHR patients for analysis of the primary outcome.
