MULTI-CENTER STUDYSUMMARY:INTRODUCTION:  Diastasis of the recti is a common pathology in puerperium, associated with middle line hernias. Endoscopic surgery allows us to restore the linea alba.METHOD: Multicenter and prospective study between April 2014 and July 2018, 215 patients were operated, 94% women with an average age of 40 years. The diagnosis was confirmed by CT (51.6%) and ultrasound (45.5%).RESULT: Diastasis of the recti was associated with midline hernias in 93.4%. Diastasis of the recti were diagnosed <50 mm (55.5%), from 51 to 80 mm (29.6%) and> 81 mm (14.9%). Plication of the recti with a barbed suture was performed. It was associated with discharge of the external oblique muscle in 8.8%, being unilateral (8%). Lightweight / intermediate (97.3%) and heavy (2.7%) polypropylene meshes, fixed with absorbable (76.2%), non-absorbable (8.8%), adhesive (7%) and 910 polyglactin stitches were placed (8%). Drainage was placed in 100% of the cases. The surgical time average was 107 minutes. Intraoperative complications (1.39%): 2 hypercapnia and 1 thermal umbilical skin lesion. Postoperative complications (12.5%): seroma (9.7%), preaponeurotic hematoma (1.4%). Hospital stay: 1.6 days. Average return to work activity was of 15 days. Clinical and ultrasound check-up at 12 months (58.6%), without complications or recurrences.CONCLUSION: Endoscopic surgery allowed us to resolve the parietal defect with plication of the recti and reinforcement preapponeurotic prosthesis, increasing the safety of the repair, without entering the abdominal cavity, reduced hospitalization, low rate of complications, without recurrence, evidencing the feasibility, security and reproducibility of this approach.KAYWORDS: PREAPONEUROTIC ENDOSCOPIC REPAIR – RECTI PLICATION - DIASTASIS RECTI

INTRODUCTION: Diastasis recti (DR) associated with midline hernias is common. Big size DR represents a clinical and cosmetic problem. Its repair is challenging, with intraoperative and postoperative risks. The adjuvant of botulinum toxin serotype A makes it possible to restoration of the linea alba by preaponeurotic endoscopic repair (REPA). METHODS: This was a retrospective study with prospective database. Between February 2019 and July 2020, six women were operated, with a mean age of 39 years and a diagnosis of DR >80 mm, with a body mass index of 27. All patients were infiltrated with 50 UR of botulinum toxin serotype A on each side, 30 days before the surgery. RESULTS: The intraoperative diagnosis of DR was 87.5 mm average, associated with midline hernias in 100%, with a mean transverse diameter of 24 mm (10–60 mm) Anatomical restoration of the linea alba was performed with a slow absorbable barbed suture. The wall was reinforced with 100% macroporous polypropylene mesh, with 83.3% atraumatic fixation and 16.6% absorbable traumatic fixation. The surgical time was 94 ± 15 min. Postoperative pain was 2/10 ± 1 according to the Visual Analog Scale, allowing a hospital stay of 18 ± 4 h. Return to work 18 ± 3 days. The mean follow-up was 9 (2–18) months by the clinical and ultrasound examination in 100%, without complications or recurrences. CONCLUSIONS: The application of botulinum toxin serotype A associated with endoscopic repair (REPA) allowed solving the big size DR and midline hernias with suture of the rectus sheath with less tension, associated with a reinforcement prosthesis, allowing a reduced hospitalization with a low level of postoperative pain, avoiding muscle release incisions, which are irreversible and not exempt from morbidity, added to the proven benefits of endoscopic access.
