BackgroundA systematic analysis was conducted of randomized controlled trials (RCTs) comparing lightweight mesh (LWM) with heavyweight mesh in laparoscopic inguinal hernia repair.MethodsData extracted from the included RCTs were analyzed according to the principles of meta-analysis.ResultsEleven RCTs encompassing 2,189 patients were analyzed. In a fixed-effects model, operating time, postoperative pain, and recurrence rate were statistically similar between LWM and heavyweight mesh. LWM was associated with fewer perioperative complications and a reduced risk for developing chronic groin pain. There was also a reduced risk for developing other groin symptoms, such as foreign body sensations, but it was not statistically significant.ConclusionsThe use of LWM for laparoscopic inguinal hernia repair is not associated with an increased risk for hernia recurrence. LWM reduces the incidence of chronic groin pain, groin stiffness, and foreign body sensations. Therefore, LWM may routinely be used in laparoscopic inguinal hernia repair. However, high-quality RCTs with longer follow-up periods are required to validate these findings.Copyright © 2013 Elsevier Inc. All rights reserved.
