Robotic abdominal wall repair: adoption and early outcomes in a large academic medical center

Robotic-assisted abdominal wall repair (RAWR) has seen an exponential adoption over the last 5 years. Skepticism surrounding the safety, efficacy, and cost continues to limit a more widespread adoption of the platform. We describe our initial experience of 312 patients undergoing RAWR at a large academic center. A retrospective review of all patients undergoing any RAWR from July 1, 2016 to March 18, 2020 was completed. Patient specific, operation specific, and 30-day outcomes specific data were collected. Univariate analysis and multivariate logistic regression were used to assess factors associated with 30-day complications. There was a steady adoption of RAWR over the study period. A total of 312 patient were included, 138 (44%) were abdominal wall repairs and 174 (56%) were inguinal repairs. The mean age of the cohort was 54.2 years (SD 16), 69% were males, and the mean BMI was 29 kg/m 2 (SD 4.8). There were two reported intraoperative events and nine operative conversions. 60 patients had at least one complication at 30-days. These include: 52 seromas, 4 hematomas, 2 surgical-site infections, 1 deep venous thrombus, and 1 recurrence at 30-days. BMI, type of hernia, and sex were not associated with complications at 30-days. The use of absorbable mesh, longer hospital stay, operative conversion, previous repair, and expert hernia surgeon were significant predictors of 30-day complications. Age, operative conversion, and previous repair were the only predictors of 30-day complications on multivariate regression. Our initial experience of 312 patients demonstrates the adoption and comparable short-term outcomes for a wide variety of robotic-assisted hernia repairs.
