The role of prophylactic antibiotics in elective inguinal tension‐free hernia repair: A systematic review and meta‐analysis

Abstract

Whether to use antibiotics to prevent surgical site infection in elective inguinal tension‐free hernia repair has been controversial. To systematically evaluate the effect of prophylactic antibiotic application in elective inguinal tension‐free hernia repair, we identified all published randomised controlled trials of the effect of prophylactic antibiotic application on elective inguinal tension‐free hernia repair were collected by computer retrieval from the China National Knowledge Infrastructure; VIP Database; Wanfang Database; China Biomedical Literature Database; and PubMed, EMBASE and Cochrane Library databases. Meta‐analysis was performed by RevMan 5.3 software. The meta‐analysis showed that the total incidence of surgical site infections [ P = 0.003] and the incidence of superficial surgical site infections [ P = 0.004] in the antibiotic group (AG) were lower than those in the non‐antibiotic group (NAG). There was no significant difference in the total incidence of postoperative infections [ P = 0.06], deep surgical site infections [ P = 0.26] and seroma [ P = 0.52] between the AG and the NAG. Based on current evidence, the application of prophylactic antibiotics in elective inguinal tension‐free hernia repair can prevent the total incidence of surgical site infections and that of superficial surgical site infections but cannot prevent the total incidence of postoperative infection events, incidence of deep surgical site infections and incidence of seroma.
