Purpose: Despite the widespread of ventral hernia repairs globally, the approach method, dissection planes, defect closure, and the choice and placement layer of mesh are an ongoing debate. We reported the details of surgical techniques, safety and feasibility for robot-assisted transabdominal transversalis fascial and preperitoneal repair (R-TATFPP) for small ventral hernia., Methods: This study included 5 cases of R-TATFPP repair among 22 cases performed by robot-assisted ventral hernia repair from 2018 to 2023 with the approval of the Institutional Review Board at St. Luke's International University and clinical ethical committee at St. Luke's International Hospital (19-R147, 22-012)., Results: There were four males and one female, with mean age of 64.4 ± 10.0 years, inclusive of two umbilical and three incisional hernias. Mean height, weight, body mass index (BMI), hernia defect length, width, operation time, console time, and hospital stay were 171.2 ± 11.8 cm, 82.4 ± 13.4 kg, 28.0 ± 2.1 kg/m 2 , 2.8 ± 1.4 cm, 3.0 ± 1.3 cm, 180 min, 133.8 min, and 2.4 days, respectively. No conversion nor complication was observed except for one acute urinary retention., Conclusion: Robot-assisted transversalis fascial and preperitoneal repair was safe and feasible for small ventral hernia with the minimal disruption to the abdominal wall architecture and structures., (© 2024 Asia Endosurgery Task Force and Japan Society of Endoscopic Surgery and John Wiley & Sons Australia, Ltd.)

Introduction: The endoscopic-assisted or endoscopic mini- or less-open sublay (E/MILOS) concept describes a contemporary approach of trans-hernial repair of ventral hernia via sublay mesh placement. The term sublay often causes confusion, and preperitoneal placement of mesh should be considered as a distinctive approach. We hereby present our experience of a novel approach, the E/MILOP approach, for the repair of primary and incisional ventral hernias., Methods: All patients who underwent E/MILOP between January 2020 and December 2022 were identified and their preoperative and perioperative characteristics, as well as postoperative outcomes, were retrospectively analyzed. The surgical procedure entailed an incision over the hernia defect and careful entrance into, and development of, the preperitoneal space trans-hernially. A synthetic mesh was placed in the preperitoneal space and the defect was closed with sutures., Results: A total of 26 patients with primary and/or incisional ventral hernias who underwent E/MILOP were identified. Three patients (11.5%) presented with two coexistent types of hernias, and out of a total of 29 hernias, there were 21 (72.4%) umbilical, four epigastric (13.8%) and four incisional (13.8%) hernias. The mean defect width was 2.7 ± 0.9 cm. All cases utilized a mesh with a mean mesh-to-defect ratio of 12.9. The mean postoperative stay was 1.9 days. Surgical site occurrence was observed in eight (30.1%) patients, but none required intervention. No recurrence was observed during a mean follow-up period of 286.7 days., Conclusion: The E/MILOP approach is a novel alternative for primary and incisional ventral hernia repair., (© 2023 Asia Endosurgery Task Force and Japan Society of Endoscopic Surgery and John Wiley & Sons Australia, Ltd.)

Extraperitoneal mesh repair for ventral hernia has garnered attention and its rate has been increasing due to concerns for the potential complications of intraperitoneal mesh repair. Recently, robotic-assisted ventral hernia repair is highlighted as a solution to the technically demanding nature of laparoscopic transabdominal or enhanced-view totally extraperitoneal retrorectus ventral hernia repair. A 78-year-old man, who had undergone robot-assisted radical prostatectomy 10 months earlier, presented with an incisional hernia of European Hernia Society Classification M3W2, length 4 cm, width 5 cm with rectus diastasis. A right single-docking robotic-assisted transabdominal retrorectus repair was performed using a 21 by 14 cm self-gripping mesh and anterior wall reconstruction was done by 0 barbed nonabsorbable running suture. There were no complications and recurrence observed during a 7 months postoperative period. Single-docking robotic-assisted transabdominal retrorectus repair was considered a good option for midline moderate-size incisional hernias from the point of view of the ease of suturing, adequateness of dissection and prevention of bowel injury., (© 2022 Asia Endosurgery Task Force and Japan Society of Endoscopic Surgery and John Wiley & Sons Australia, Ltd.)
