Abstract
The present study systematically evaluated the clinical effects of mesh-plug and Lichtenstein herniorrhaphy in the treatment of primary inguinal hernia. PubMed, Embase, and the Cochrane Library (cut-off: May 25, 2020) databases were searched to select randomized controlled trials (RCTs) on mesh-plug and Lichtenstein herniorrhaphy for the treatment of primary inguinal hernia. Articles that met the inclusion criteria were screened and evaluated for quality. RevMan 5.3 software was used to perform a meta-analysis of operation time, discomfort in the inguinal region, haematoma, seroma, infection, time to return to normal activities, incidence of postoperative chronic pain, and recurrence rate. Eleven RCTs with 1457 patients in the mesh-plug group and 1472 in the Lichtenstein group were included. Meta-analysis showed that the mesh-plug herniorrhaphy group had a shorter operation time than the Lichtenstein herniorrhaphy group [P < 0.0001] but a longer time to return to normal activities after surgery [MD = 1.48, 95% CI (0.58, 2.38), P = 0.001]. There were no significant differences in postoperative discomfort in the inguinal region [P = 0.90], seroma [P = 0.10], haematoma [P = 0.27], infection [P = 0.40], incidence of postoperative chronic pain [P = 0.90], or recurrence rate [P = 0.77] between groups. Mesh-plug herniorrhaphy requires a shorter operation time than Lichtenstein herniorrhaphy, and there is no significant difference in postoperative complications or recurrence rate between the two methods.
