P-068 RESULTS OF THE OPEN INTRAPERITONEAL ONLAY MESH TECHNIQUE WITH A PREFORMED PATCH FOR PRIMARY VENTRAL HERNIA AND INCISIONAL HERNIA

Abstract

Abstract Aim Primary ventral hernias and incisional hernias are frequent, but long–term results of their repair with a preformed patch are scarce. The aim was to evaluate the surgical results of the treatment of these hernias with the open intraperitoneal onlay mesh (open IPOM) technique, and to determine the needed follow–up for recurrence. Material and methods Observational retrospective single institution study of all consecutive patients intervened for ventral or incisional hernia with diameter inferior to 4 cm, from January 2013 to June 2020. The surgical repair was performed according to the open IPOM technique with a preformed patch and the defect was left unclosed. Relapsed hernias, those with a defect ≥ 4 cm, and lateral wall hernias were excluded. Results A total of 146 patients were intervened: 61.6% with umbilical hernias, 8.2% with epigastric hernias, 26.7% with trocar incisional hernias, and 3.4% with other incisional hernias. The global recurrence rate was 7.5% (11/146). Specifically, there it was 7.8% in umbilical hernias, 0% in epigastric hernias, 7.7% in trocar incisional hernias, and 20% (1/5) in other incisional hernias. The median time for recurrence was 14 months (IQR: 4,4–18,7). The median presential follow–up was 17,4 months (IQR: 6,5–27,3), and the median telematic follow-up was 36,9 months (IQR: 27,2–49,6). Conclusions The open IPOM technique with a preformed patch offers good results for the treatment of ventral and incisional hernias. A 2-year follow-up is still needed for the recurrence diagnosis. Note The preformed patch used was the Parietex™ Composite Ventral Patch (Medtronic, Minneapolis, MN, EEUU).
