A Comparative Study of Retrorectus Mesh Placement Versus Properitoneal Mesh Placement in Open Repairs of Ventral Hernias

Background Ventral hernias affect millions of patients each year. Surgery is the main line of management and various techniques have been advocated; however, mesh repair has become the norm and different approaches have been described regarding the plane of mesh fixation, but none of them are standardized. Open repair is commonly practiced, and the two most commonly performed methods are retrorectus and properitoneal mesh placement. Objectives To compare the postoperative outcomes between the retrorectus plane and the properitoneal plane of fixation of mesh in open ventral hernia repair. Methods Between September 2018 and August 2020, 56 patients with midline ventral hernia admitted to Ramaiah Hospital, Bengaluru were chosen for this prospective comparative study. Group A had 28 patients who underwent open retrorectus mesh repair and 28 patients in Group B underwent open properitoneal mesh repair. The postoperative outcomes were studied in terms of operating time, postoperative complications, and early recurrence at the end of six months and 24 months post-surgery. Results The operative time for retrorectus mesh placement was significantly lower than properitoneal mesh placement. The latter had a higher complication rate overall with an incidence of 18%, with seroma being the most common complication; however, the difference in complication rates was not statistically significant. Skin necrosis was identical in both groups and 0% of cases in both groups had SSI or mesh infection. Three patients (10.71%) in the retrorectus group and two patients (7.10%) in the properitoneal group developed recurrence at 24 months follow-up. Conclusion Retrorectus mesh repair and properitoneal mesh repair in open ventral abdominal hernias have equally good postoperative outcomes.
