BJS-06 LAPAROSCOPIC INTRACORPOREAL RECTUS APONEUROPLASTY (LIRA) TECHNIQUE VERSUS INTRAPERITONEAL ONLAY MESH CLOSING THE DEFECT (IPOM PLUS) FOR VENTRAL HERNIA REPAIR: COMPARATIVE RESULTS AT MEDIUM FOLLOW-UP

Abstract

Abstract Background The primary aim of this prospective study is to compare the postoperative outcomes between LIRA technique and IPOM plus, in terms of recurrence and bulging rates at one-year follow-up; the secondary aim is to compare the postoperative complications, seroma and pain at 30 days and one-year after surgery. Methods Patients with midline ventral hernia of 4–10 cm in width were included. Seromaand recurrence was evaluated by Computed tomography scan 1 month and 1 year after surgery. Pain was evaluated using the visual analogue scale score. Results Forty-five and forty-seven patients underwent LIRA and IPOM plus, respectively. Preoperatively, smoke habitus rate was statistically significantly higher in LIRA group (20 patients, 44.4%) in comparison to IPOM group (5 patients, 10.6%) (p=0.0001). Statistically significant differences were not considering the intraoperative variables. Two bulgings (4.4%) occurred in the LIRA group, while in the IPOM group occurred 10 bulgings (21.3%) and three recurrences (6.4%) (p=0.017 and p=0.085, respectively). Postoperatively, seven (15.6%, Clavien-Dindo I) and four complications (8.5%, two Clavien-Dindo I and two Clavien-Dindo III-b) occurred in the LIRA and in the IPOM group, respectively (p=0.298). One month after surgery, clinical seroma, occurred in five (11.1%) and eight patients (17%) in the LIRA and in the IPOM group, respectively (p=0.416). During follow-up, pain reduction occurred, without statistically significant differences. Conclusions LIRA showed lower bulging and recurrence rates in comparison to IPOM plus at one-year follow-up. Further prospective studies, with a large sample of patients and longer follow-up are required to draw definitive conclusions.
