Evaluation of light weight large pore mesh versus heavy weight small pore mesh in total extraperitoneal repair of inguinal hernia: A prospective randomized study

BACKGROUND: The type of mesh to be used in laparoscopic groin hernia repair has always been debatable whether to use lightweight (LW) or heavyweight (HW) mesh. The study compares the lightweight large pore mesh with HW small pore mesh in total extraperitoneal groin (TEP) hernia repair and its outcome. MATERIALS AND METHODS: A total of 50 patients, who met the inclusion criteria, were randomized in the two groups. In group I (n = 25) LW large pore mesh (pore size 1 mm) was used whereas in group II (n = 25) HW small pore mesh (pore size < 0.65 mm) was used. Outcomes were observed with respect to complications, recurrence, and patient satisfaction. Statistical analysis was performed using χ2 test and student t test. RESULTS: Mean age of the patients group I was 45 ± 18.52 while in group II it was 48.88 ± 20.529 years. The complication rates were comparable between the two groups. However, seroma formation was higher in group II. The occurrence of groin pain and foreign body sensation between the two groups was comparable after 6-month follow-up. No recurrence was reported in either of the groups. CONCLUSION: Although there was no significant difference between the two groups, but the present study showed some advantage of LW mesh over HW weight mesh in TEP with respect to complications and patient satisfaction.
