Comparative study between Onlay and Sublay placement of polyproline mesh in ventral hernia repair

Abstract

entral hernia repair is one of the most common surgical operations performed all over the world. Onlay and sublay mesh repairs are the commonly performed techniques for the same. However, the debate still continues about the superiority of both techniques over each other. The aim of this study was to compare the outcome of the onlay versus sublay mesh repair for ventral hernia. Our study was performed in Ain shams university hospital at the general surgery department on 60 patients half of them underwent onlay hernioplasty and the other half underwent sublay hernioplasty technique. Ventral hernias can be classified according to its site into epigastric, paraumbilical, umbilical, lumbar and incisional hernia. Ventral hernia can also be categorized according to their characteristics into reducible, irreducible or incarcerated, strangulated and recurrent ventral hernia., the repair of hernias varies from primary repair of the defect to mesh reinforcement. Numerous studies have been conducted to understand the hernial mechanism and the methods of repair, all studies stressed on managing hernial defects as a part of generalized abdominal wall disorders. Careful evaluation of the patient who presents with an abdominal defect reveals predisposing factors for herniation either for primary or for secondary ventral
