Non-mesh Desarda Technique Versus Standard Mesh-Based Lichtenstein Technique for Inguinal Hernia Repair: A Systematic Review and Meta-analysis

The aims of the present systematic review and meta-analysis were to compare non-mesh Desarda technique with standard mesh-based Lichtenstein technique for inguinal hernia repair. A systematic literature search for RCTs comparing between DT and LT was conducted using electronic databases and Google scholar service. Studies were evaluated for recurrence and post-operative complications. We pooled the data using fixed effects model and random effects model after assessing the heterogeneity among the included studies. A total number of 8 RCTs studies were included in this meta-analysis with total number of 3177 patients divided between Desarda group and Lichtenstein group as follows: 1551 patients and 1,626 patients, respectively. There was no difference in terms of recurrence between the Desarda repair and Lichtenstein repair groups [P = 0.44]. There was a lower rate of overall post-operative complications [P = 0.003], seroma [P = 0.0004] and surgical site infections (SSIs) [P = 0.04] in the Desarda group. DT and LT were found to have comparable results in terms of recurrence rate, haematoma formation, testicular atrophy and time to return to normal daily activity/work. DT is superior to LT in terms of reducing post-operative mesh-attributed complications, such as SSI and Seroma formation.
