    Abstract:
    INTRODUCTION: Patients with umbilical or epigastric hernias benefit from mesh- based repairs, and even more so if a concomitant rectus diastasis (RD) is present. The ideal technique is, however, still under debate. In this study we introduce the minimal invasive linea alba reconstruction (MILAR) with the supraaponeurotic placement of a fully absorbable synthetic mesh. MATERIALS AND METHODS: Midline reconstruction with anterior rectus sheath repair and mesh augmentation by an open approach is a well-known surgical technique for ventral hernia repair. Between December 1, 2016, and November 30, 2017, 20 patients with symptomatic umbilical and/or epigastric hernias, and coexisting RD underwent a minimally invasive complete reconstruction of the midline through a small access route. The inner part of both incised and medialized anterior rectus sheaths was replaced by a fully absorbable synthetic mesh placed in a supraaponeurotic position. RESULTS: Patients were hospitalized for an average of 4 days and the mean operating time was 79 minutes. The mean hernia defect size was 1.5 cm in diameter and the mean mesh size was recorded as 15.8 cm in length and 5.2 cm in width. Two patients sustained surgical postoperative complications in terms of symptomatic seroma occurrences with successful interventional treatment.The early results (mean follow-up period of 5 months) showed no recurrences and only 1 patient reported occasional pain following exertion without rest. DISCUSSION: MILAR is a modification of the recently published endoscopic linea alba reconstruction restoring the normal anatomy of the abdominal wall. A new linea alba is formed with augmentation of autologous tissue consisting of the plicated anterior rectus sheaths. Supraaponeurotic placement of a fully absorbable synthetic mesh eliminates potential long-term mesh-associated complications. Regarding MILAR, there is no need for endoscopic equipment due to the uniquely designed flexible lighted retractors, meaning one assistant less is required.
