OC-118 INTRAPERITONEAL ONLAY MESH (IPOM) TECHNIQUE FOR THE TREATMENT OF PRIMARY AND INCISIONAL VENTRAL HERNIAS – OUR EXPERIENCE

Abstract

Abstract Aim IPOM technique is a well-established technique for the repair of primary and incisional ventral hernias. In this retrospective observational study, we evaluated the application of IPOM technique with the use of polypropylene composite meshes (1) Materials and Methods 194 patients who underwent a laparoscopic hernia repair from 2011 to 2022 for either a primary(Group A= 83) or an Incisional (group B=111) ventral hernia were included in the study. The primary endpoint was the evaluation of the recurrence rate and the mean hospital stay in the two Groups. All the procedures were performed through three abdominal trocars executing cold adhesiolysis to release the contents of the hernial sac without dissecting the latter. Partial peritonectomy was then performed by blunt dissection to promote adhesion of the mesh. Mesh fixation was achieved using trans-parietal suture and resorbable tackers. Results The two groups showed significative differences in baseline characteristics with Group B including older patients with higher ASA scores, defect number and dimension, rate of later hernia and defect closure. One-day surgery setting was more common in group A (80.7% vs 64.0%, p=0.01). The defect closure shows increasing hospital stay in both groups, with statical significance only in group A. The recurrence rate was slightly higher in group A (3.6% vs 2.7%, p=0.41) with comparable median follow-up (42 vs 45 months, p=0.41). Conclusion Our clinical experience showed that IPOM technique with polypropylene composite meshes is a safe and effective approach for the treatment of primary and incisional hernias.
