SP7.2.5 Robotic incisional/ventral hernia repair is feasible approach compared to laparoscopic repair: a systematic review

Aims Robotic incisional/ventral hernia repair (R-IVHR) is gaining popularity due to higher safety as well as feasibility profile. The objective of this study is to present a systematic review exploring the role of robotics compared to laparoscopic approach in the management of incisional/ventral hernia. Methods A systematic review of all types of comparative studies until January 2021 published on Embase, Medline, PubMed, PubMed Central and Cochrane databases reporting the clinical outcomes in patients undergoing either R-IVHR versus Laparoscopic (L-IVHR) was performed. Results A total of 8289 patients in 7 studies were included. There was minimal heterogeneity (Tau2 = 0.29, chi2 = 9.10, df, I2 = 45 %) among included studies for the variables of recurrence rate and post-operative complications, but statistically significant heterogeneity (Tau2 = 1.05, chi2 = 132.81, I2 = 96 %) was observed for the duration of operation. In the random effects model analysis using the statistical software Review Manager, statistically the R-IVHR prolonged the duration of operation (Standardized mean difference, 2.24; 95% CI, 1.37, 3.11; z = 5.06; P = 0.00001) but the post-operative complication rate (OR 0.63; 95% CI, 0.30, 1.34; z = 1.20; P = 0.23) as well as the recurrence rate (OR 0.63; 95% CI, 0.14, 2.74; z = 0.62; P = 0.53) were similar. Conclusion R-IVH repair is feasible and safe, but the duration of operation is significantly longer. Major multi-center randomized controlled trial is mandatory to assess the long terms outcomes and cost effectiveness before the routine use of R-IVHR.
