The comparison of self-gripping mesh and conventional mesh in laparoscopic inguinal hernia repair: the results of meta-analysis.

Self-gripping mesh is widely used in laparoscopic inguinal hernia repair and some researches report its advantages compared with conventional mesh. The aim of this study was to assess outcomes of self-gripping mesh and conventional mesh in laparoscopic inguinal hernia repair. A systematic literature review was undertaken to identify studies comparing the results of self-gripping mesh and conventional mesh in laparoscopic inguinal hernia repair. Outcomes, including recurrence, chronic pain, operation time, hematoma, seroma and infection, were measured. Four randomized controlled trials and 1 prospective comparative study were analyzed. The incidence of chronic pain in self-gripping group was significantly lower than that in conventional group (OR 0.43, 95% CI 0.20, 0.93, P = 0.03), and there was no significant difference in hernia recurrence (OR 0.31, 95% CI 0.03, 3.06, P = 0.32), operation time (MD 0.06, 95%CI - 2.32, 2.44, P = 0.96), hematoma (OR 1.01, 95% CI 0.33, 3.07, P = 0.99) and seroma (OR 0.90, 95% CI 0.49, 1.66, P = 0.73). Laparoscopic inguinal hernia repair using self-gripping mesh is associated with a decreased incidence of chronic pain compared with conventional mesh, without increased postoperative complications.
