Abstract

The surgical management of midline ventral hernias complicated by concomitant diastasis recti presents a significant clinical challenge. The Endoscopic Onlay Repair (ENDOR) offers a minimally invasive solution, effectively addressing both conditions. This study focuses on describing the adaptation of ENDOR to a robotic platform, termed R-ENDOR, aiming to report initial outcomes along with other established robotic surgical approaches. This retrospective case series study included consecutive adult patients who underwent R-ENDOR approach from October 2018 to April 2023, performed by a single surgeon. A comprehensive description of the surgical technique is included. Patient demographics, operative, and hernia-specific characteristics, as well as clinical outcomes are described. A total of 15 patients undergoing R-ENDOR for ventral hernia repair with diastasis recti plication were included. The median age was 59years (IQR 42-63), with 60% (n = 9) female patients. The majority (86%, n = 13) had an ASA score of ≤ 2, and the median BMI was 24kg/m2, with 20% (n = 3) classified as obese. Median hernia size was 2cm (IQR 2-2.25), with a median diastasis length of 19cm (IQR 15-21.5) and width of 4cm (IQR 3-6). The median operative time was 129min (IQR 113-166). Most repairs (93%, n = 14) were reinforced with mesh, predominantly self-fixating (73.3%, n = 11). Eighty percent of patients (n = 12) were discharged on the same day, with a median follow-up of 153days (IQR 55-309). Notable complications included clinically significant seromas in 20% of patients (n = 3), long-term hypoesthesia in 40% (n = 6), and readmission in one patient (6.6%) for surgical site infection (SSI) requiring IV antibiotic therapy. Midline ventral hernias associated to diastasis recti can be managed robotically by ENDOR with safe and consistent 90-day outcomes in a carefully selected group of patients.
