P148 LIRA TECHNIQUE AFTER MEDIUM FOLLOW UP. RESULTS OF A NEW MINIMAL INVASIVE PROCEDURE IN VENTRAL HERNIA REPAIR

Abstract

Abstract Aim LIRA technique (Laparoscopic Intracorporeal Rectus Aponeuroplasty) was described in 2018 in order to reduce the tension in the midline as an alternative to defect closure (CD) in Laparoscopic Ventral Hernia Repair. We present our results in LIRA series in patients over 1-year follow-up. Material and Methods A prospective controlled study was conducted from January 2015 to December 2020 to evaluate an elective new procedure (LIRA) performed on patients with midline ventral hernias w2 (EHS Classification). Data analyzed included patient demographics, operative parameters and complications. A Tomography was performed preoperatively and postoperatively (1 month and 1 year) to evaluate recurrence, distance between rectus and seroma Results 49 patients were included. Mean Age was 58± 10.59 years old and BMI 33.11± 6.61 kg/m2. Mean width of the defect was 6.19± 1.49 cm. Average VAS (24 h) was 5.09 ± 5, 0.38(1 month) and 0 (1 year). Mean preoperative distance between rectus was 5.55± 1.61 cm; postoperative was 2.15 ± 0.79 cm (1 month) and 2.20±0.68 cm (1 year). Radiological seroma at first month was detected in 40%. Seroma after 1 year was 4,08% Mean follow-up was 24 months. Bulging was detected only in 1 case (2.04%) of our series after 1 year follow up. No recurrence is data. Conclusions LIRA technique could be considered as an alternative to CD for w2 defects with a low rate of complication, and could be related to a low rate of postoperative pain with no recurrence and a low rate of bulging compared to CD, being a safe, feasible and reproducible technique.
