Traditional polypropylene and lightweight meshes in totally extraperitoneal inguinal herniorrhaphy

Background: Placement of a prosthetic mesh is integral to successful totally extraperitoneal (TEP) herniorrhaphy. Available meshes have supported the surgical efforts well but search for an ideal mesh continues. Post-herniorrhaphy pain is an index of patient reported outcomes (PRO). The pain is attributable to balloon dissection, cautery, sutures, tackers and prosthesis. Reducing polypropylene content of the mesh is associated with attenuated inflammatory response by the host and improved compliance and comfort. We report the difference in PROs in TEP herniorrhaphy with either heavy polypropylene (PPM) or light weight mesh (LWM) being used for the repair. Patients and methods: From June 2004 to December 2005, consecutive candidates for TEP herniorrhaphy were enrolled for this prospective study with an informed consent and compliance to Ethics guidelines. They were operated under general anesthesia (GA) on a day care basis using either PPM or LWM meshes as per the patient's choice. Operative and postoperative PRO were statistically analyzed by an independent doctor using the Microsoft Office Excel 2003. Results: One hundred fourteen (84 PPMs and 30 LWMs) TEP herniorrhaphies were performed under GA on 57 male patients without any exclusion, on a day care basis. There was no technical difficulty, operative complications, conversion or prolonged hospital stay in either group. Patients of LWM reported better outcome in regards to pain, NSAID usage, seroma and recurrence. All patients of LWM reported an earlier return to activity. Conclusion: Light weight meshes result in comparatively better patient reported outcomes in TEP inguinal herniorrhaphy as compared to heavy polypropylene meshes. (C) 2009 Surgical Associates Ltd.
