A Comparative Study between Intra-Operative Difficulties and Early Postoperative Complications in Laparoscopic Inguinal Hernia Repair Using Conventional Polypropylene Mesh and 3D Mesh – A Meta-Analysis

Abstract

Abstract Background The fundamental mechanism of abdominal wall hernia formation is the loss of structural integrity at the musculotendinous layer. The exact cause of inguinal hernia is still unknown but the factors contributing in its occurrence include; preformed congenital sac, chronic passive rise in the intra-abdominal pressure and weak abdominal wall. Objective To assess laparoscopic inguinal hernia repair using two different meshes: The conventional polyproline mesh and the three-dimensional (3D) mesh, as regard the operative application time, early post-operative complications including seroma, early pain, sensory impairment, surgical site infection (SSI) and hospital stay time using meta-analysis approach. Patients and Methods In our study ten trials included, three trials regarding 3d mesh versus conventional mesh in laparoscopic inguinal hernia repair including 9,118 participants were selected from electronic databases. Three trials regarding 3d mesh and four trials regarding polyprolene mesh. Data Sources Medline databases (PubMed, Medscape, ScienceDirect. EMF-Portal) and all materials available in the Internet till 2021. Results There is significant heterogeneity among trials (P = 0.002, I2 = 84%), mean difference 1.17, 95% CI -2.18, 4.52 and there is no statistically significance z = 0.49. Conclusion There is no difference between conventional polyprolene and 3d mesh regarding intra- operative difficulties (operative time) and post-operative complications (chronic pain, recurrence, operative time and seroma).
