Robotic Intracorporeal Rectus Aponeuroplasty: Early Experience of a New Surgical Technique for Ventral Hernia Repair

摘要

Introduction: The laparoscopic intracorporeal rectus aponeuroplasty (LIRA) was developed as an alternative for minimally invasive ventral hernia repair. This technique allows the closure of the defect and restoration of the midline without tension by plication of both aponeurosis of the abdominal rectus muscles combined with a minimally invasive intraperitoneal underlay mesh repair. The objective of this study is to report our early experience with the Robotic-LIRA (R-LIRA) technique and its safety and short-term efficacy. Methods: We performed a retrospective analysis of patients undergoing R-LIRA repair for ventral hernias from March 2019 to April 2022. Results: Eight patients underwent R-LIRA from March 2019 to April 2022. Median age was 47 years (interquartile range [IQR] 34.5–62.8). Median body mass index was 34.2 kg/m2 (IQR 29.9–35.2). Four patients (50%) had a primary ventral hernia being one M2, two M3, and one M2/M3. There were three incisional hernias, being one recurrent, 6 patients (75%) had associated diastasis of the rectus muscle and 1 patient presented pure diastasis. The median hernia width was 4 cm (IQR 2–6), and the median defect area was 16 cm2 (IQR 4–42). The median mesh area was 290 cm2 (IQR 211.2–300). In all cases, a barbed suture was also used for mesh fixation, and tackers were added in 4 cases. The median operative time was 172 minutes (IQR 139.8–293.3). The median length of stay was 0.5 days (IQR 0–1.8), and the median follow-up was 20 days (IQR 16–46). Conclusion: The R-LIRA has been shown to be safe and feasible for ventral and incisional hernia repairs with or without Diastasis of the Rectus Abdominis Muscle in the short term.
