Abstract
Introduction: The enhanced-view extraperitoneal (eTEP) technique was first described for minimally invasive inguinal hernia repairs and later for laparoscopic ventral hernia repair. The objective of this study was to report our early experience and learning curve (LC) with the robotic-assisted eTEP (R-eTEP) approach. Materials and Methods: We performed a retrospective analysis of patients undergoing R-eTEP repair for ventral hernias from December 2018 to September 2021. A single surgeon operative time (OT)-based LC was evaluated. Results: A total of 81 patients underwent an R-eTEP from December 2018 to September 2021. Sixty-five patients were ultimately included in our analysis. Fifty-seven patients underwent eTEP-Rives-Stoppa (RS) and 8 patients underwent eTEP-transversus abdominis release (TAR). The median age in the whole cohort was 57 years (interquartile range [IQR] 51.5-64.5 years) with no difference between the groups. The median body mass index (BMI) was 31 kg/m2 (IQR 27-34.7 kg/m2) in the eTEP-RS group and 29.7 kg/m2 (IQR 28.5-31 kg/m2) in the eTEP-TAR group. There were 36 incisional hernias (63%) in the eTEP-RS group and 8 (100%) in the eTEP-TAR group. There were 14 recurrent hernias (25%) in the eTEP-RS group and 2 (25%) in the eTEP-TAR group. The LC was evaluated only in the eTEP-RS cases. We divided the cohort into 3 chronological groups (G1, G2, and G3), including 19 cases each. The median OT in each group was 177 (IQR 147-200), 153 (IQR 127-187), and 125 minutes (IQR 106-152 minutes), respectively. There was no difference in the median OT between G1 and G2 (P = .390). G3 had a shorter median OT than G2 (P = .02) and G1 (P = .001). There was no difference between these groups in median age, BMI, defect area, defect width, and mesh area. Conclusions: The R-eTEP approach has been shown to be safe and feasible for ventral and incisional hernia repairs. A statistically significant decrease in OT was observed after 38 cases.
