New Study Shows Robotic-Assisted Surgery Benefits for Inguinal Hernia Repair
An inguinal hernia occurs when tissue, such as a part of the intestine, pushes through a weak area of the lower abdominal wall, specifically in the inguinal canal. Inguinal hernias often develop over time due to strain and stress on weakened muscles in the groin area, and are typically repaired via open surgery.
Seven surgeons from six hospitals across the U.S. conducted the study—the largest, multi-center comparative study of robotic-assisted and open surgery for inguinal hernia repair, involving 1,254 subjects. The study, entitled “Open versus robotic-assisted transabdominal preperitoneal (R-TAPP) inguinal hernia repair: a multicenter matched analysis of clinical outcomes,” compared each surgeon’s initial, consecutive robotic-assisted inguinal hernia repair cases to open, consecutive inguinal hernia repair cases by the same surgeons.
After adjusting for potential differences in patient characteristics, an analysis of 444 patients in each study group showed robotic-assisted surgery associated with a significantly lower rate of complications after discharge through 30 days. Both surgical approaches showed similar rates of intra- and post-operation complications prior to discharge.
None of the patients undergoing a robotic-assisted inguinal hernia repair returned for reoperations related to the inguinal hernia repair within 30 days after discharge—whereas, five patients who received open surgery required reoperations related to their inguinal hernia repair during the same time period. Furthermore, a multivariate analysis showed open repair as well as patient age older than 65 as risk factors for complications after discharge through 30 days.
“Results from this study support the adoption of robotic-assisted, minimally invasive repair for inguinal hernia,” said
“Most inguinal hernia surgeries are still performed via open surgery,” said Curet. “The lower rate of complications after discharge through 30 days—especially the lower reoperation numbers—show that appropriately selected patients may benefit from minimally invasive surgery for this procedure.”

Important Safety Information
Surgical Risks of Hernia Repair (ventral, incisional, umbilical, inguinal): recurrence, bowel injury, infection of mesh, urinary retention. For inguinal hernia repair: testicular injury.
Patients should talk to their doctor to decide if da Vinci Surgery is right for them. Patients and doctors should review all available information on non-surgical and surgical options and associated risks in order to make an informed decision.
Serious complications may occur in any surgery, including da Vinci® Surgery, up to and including death. Serious risks include, but are not limited to, injury to tissues and organs and conversion to other surgical techniques, which could result in a longer operative time and/or increased complications.

Individual surgical results may vary.
