Efficacy of Partially Absorbable versus Non-Absorbable Mesh in Laparoscopic Inguinal Hernia Repair: A Comparative Study

Introduction: The selection of mesh material is a critical factor influencing patient outcomes in hernia repair, potentially outweighing the impact of the surgical technique employed. Research has compared polypropylene mesh with modified composite mesh (a combination of polypropylene and polyglactin), showing that composite mesh results in fewer foreign body reactions, reduced post-operative complications, and improved long-term quality of life. This study aimed to evaluate and compare the early outcomes of non-absorbable polypropylene mesh versus partially absorbable composite mesh in laparoscopic inguinal hernia repair. Methods: The study included 78 patients with elective reducible indirect inguinal hernias. The participants were divided into two groups of 39 each: Group A, which received partially absorbable composite lightweight meshes, and Group B, which received non-absorbable polypropylene meshes. All patients underwent laparoscopic inguinal hernia repair using the transabdominal preperitoneal (TAPP) approach. Post-operative comparisons between the groups were made based on parameters such as age distribution, inguinodynia, analgesia requirements, foreign body sensation, presence of lumps (hematoma or seroma), and return to work activities, and recurrence rates. Results: The average age of the patients was 51.14 ± 12.91 years, with the majority falling in the 51–60 years age group. Initially, no significant difference in transient neuralgia was observed between the two groups. However, at six weeks post-operation, Group A reported significantly less pain. Foreign body sensation was notably higher in Group B, though this difference was not significant over time. Conclusion: The findings suggest that composite mesh may be preferable for laparoscopic inguinal hernia repair, as it is associated with reduced pain, less foreign body sensation, and a quicker return to work compared to polypropylene mesh.
