BJS-01 NATIONWIDE ANALYSIS OF SHORT-TERM OUTCOMES AFTER OPEN VS. ROBOT-ASSISTED REPAIR OF VENTRAL HERNIA

Abstract

Abstract Background The aim was to evaluate short-term outcomes after robot-assisted and open repair of primary ventral and incisional hernia. Methods Nationwide register-based cohort study with data from the Danish Ventral Hernia Database and the National Danish Patients Registry from January 1, 2017 to August 22, 2022. Robot-assisted ventral hernia repairs were propensity score matched 1:3 with open repairs according to the confounding variables defect size, type of hernia, Charlson comorbidity index score, and age. Logistic regression analyses were performed for factors associated with length of stay > 2 days, readmission, and reoperation within 90 days. Results A total of 550 and 1,655 patients underwent robot-assisted and open repair, respectively. The mean length of hospital stay in days was 0.5 vs. 1.9 for robot-assisted and open approach, respectively, (P < 0.001) and open approach was correlated with risk of length of stay > 2 days (OR 4.69, CI 6.56–7.85, P < 0.001). The incidence of readmission and reoperation within 90 days of discharge was significantly lower after robot-assisted repair compared to open approach (7.0% vs. 15.6%, P < 0.001) and (2.0% vs. 4.4%, P = 0.013), respectively. Open approach was independently associated with increased risk of readmission and reoperation (OR 2.46, CI 1.73–3.51, P = 0.005) and (OR 2.30, CI 1.21–4.38, P = 0.011), respectively. Conclusion Robot-assisted ventral hernia repair is safe and feasible and associated with shorter length of stay and decreased risk of readmission and surgical reintervention compared with open ventral hernia repair.
