Abstract
BackgroundWhether the effect of the unfixed mesh during laparoscopic total extraperitoneal (TEP) inguinal hernia repair can lead to hernia recurrence remains controversial. MethodsThe PubMed, Cochrane Library, and EMBASE databases were searched to retrieve clinical randomized controlled trials (RCTs) comparing nonfixation of mesh and fixation of mesh in TEP inguinal hernia repair, and we performed a metaanalysis with RevMan 5.3 software. ResultsFifteen RCTs were included in the metaanalysis, which showed that the operation time (P = 0.001) of the unfixed mesh group was shorter than that of the fixed mesh group; additionally, the postoperative 24-h pain score (P = 0.04) and incidence of urinary retention (P = 0.001) were lower in the unfixed mesh group. There was no significant difference between the unfixed mesh group and the fixed mesh group in terms of hospital stay (P = 0.47), time to resume normal activities (P = 0.51), incidence of haematoma (P = 0.96), incidence of chronic pain (P = 0.20), and recurrence rate (P = 0.09). ConclusionUnfixed mesh in TEP inguinal hernia repair shows no elevated recurrence rates compared to fixed mesh and is clinically safe.
