OC-063 REPAIR OF UMBILICAL HERNIAS ASSOCIATED TO DIASTASIS USING LAPAROSCOPIC ENDOSCOPIC EXTRAPERITONEAL STAPLE BASED SUBLAY MESH TECHNIQUE (LEESS)

Abstract

Abstract Aim Patients with symptomatic umbilical hernia with associated rectus diastasis represent an increasing clinical problem. The objective was to analyze feasibility and safety using a novel surgical approach: laparoscopic extraperitoneal endoscopic staple-based sublay operation (LEESS). Methods Observational study with all patients for patients who underwent LEESS and a minimum follow-up of 1 year. Data was obtained from a prospective mantained database at Herniamed Registry Results 81 patients were operated from January 1, 2016, to June 30, 2020. Mean operative time was 100 (range, 15–200) min and mean length of hospital stay was 5 (range, 1–9) days. The overall 30 days postoperative morbidity was 12.34%: 2 (2.4%) developed a symptomatic subfascial seroma (minor complication); 2 (2.4%), a postoperative bleeding; 2 (2.4%), mild wound infection without mesh infection; and 1 (1.23%) of internal herniation through a defect in the posterior rectus sheath suture line. There were no surgery-related deaths (in-hospital mortality, 0). After a total follow-up of 12 months, 54 patients out of 81 (rate, 69.3%) recorded their information in the registry; 9 (16.7%) reported pain. The ratio of “Pain at rest” (5.6%) was significantly less than preoperatively (58.8%; p<0.001). “Pain during exercise” (11.1%) is significantly less than preoperatively (58.8%; p<0.001). Conclusion The LEESS technique with mesh augmentation appears to be an innovative, minimally invasive, feasible and safe surgical procedure for treatment of patients with symptomatic ventral midline hernia
