Original Study


Objectives The aim of the study was to compare between two techniques of mesh placement in uncomplicated ventral hernias, onlay (mesh on external oblique) versus sublay (mesh in the retromuscular space), to establish the standard technique for treatment of such cases. Background Ventral hernias are commonly encountered in surgical practice. The estimated incidence of ventral hernia is 2-10%. Despite the high frequency of surgical repair, the optimal approach for abdominal ventral hernias is still under discussion. Patients and methods This prospective study included 40 consecutive adult patients with uncomplicated ventral hernia, either primary or secondary. The patients were divided into two groups. Group A (n = 20) was operated upon following the onlay mesh repair technique and group B (n = 20) was operated upon by means of the sublay mesh repair technique. All patients were evaluated as regards operative time and postoperative complications. Results were documented and statistically analyzed. Results In this study, sublay use of the mesh in the treatment of ventral hernia significantly reduced the time to remove the drains (which was longer in the onlay mesh group; P = 0.001), seroma formation after drain removal (which was significantly higher in the onlay mesh group; P = 0.010), and wound infection (which was significantly higher in the onlay mesh group; P = 0.010) in comparison with onlay mesh repair. Conclusion We conclude that retromuscular (sublay) mesh repair is the ideal technique for ventral hernia repair.
