Brief Summary:
Inguinal hernia repair is one of the most commonly performed surgeries around the world It accounts for approximately 75 of all abdominal wall hernias and presents a lifetime risk of 27 in males and 3 in females Since the modern concept of surgical hernia repair described by Bassini in 1887 with the technique that bears his name several techniques have been developed in the last century in order to improve surgical outcomes after inguinal hernia repair
Different open repairs such as anterior Shouldice McVay or posterior Stoppa approach were described and developed until Lichtenstein described the tension-free hernioplasty concept supported by the use of a prosthetic mesh to repair the hernia defect Notable Improvements were observed with this technique in terms of recurrence pain and discomfort in comparison with previous tension repairs Considerable advantages over open repair have been obtained with the introduction of minimally invasive surgery to inguinal hernia repair in terms of patient comfort and recurrence rates
Regarding prosthetic material meshes have evolved since the first Dacron mesh used by Lichtenstein First generation meshes were manufactured using more material and for this reason they have been described as heavyweight meshes New generation meshes have been designed with less material in order to diminish the inflammatory response and foreign body reaction providing less chronic pain with similar recurrence rates than heavyweight meshes The density or weight of the mesh measured in gm2 is inversely proportional to the size of the pore and lately it has been reported that one of the main aspects related to prosthetic materials is pore size Large pore meshes use less material consequently they have been associated with a better tissue ingrowth The large pore of lightweight meshes is conditioned by the less amount of material used
All previous studies compare both light and heavyweight polypropylene meshes But in order to get a proper comparison of the behavior of meshes in the inguinal region it is important to include the material and the pore size The aim of our study is to compare patient-reported outcomes with the use of either a Polytetrafluoroethylene PTFE large pore mesh LP-PTFE vs a small pore polypropylene mesh SP-PPL

Detailed Description:
Patients fitted for laparoscopic bilateral inguinal hernia repair will be randomized to recieve one of both meshes on study in both inguinal sides
