Asymptomatic Mesh Infection 6 Years After Laparoscopic Totally Extraperitoneal Inguinal Hernia Repair: a Rare Case Report

Background: Totally extraperitoneal(TEP) inguinal hernia repair is a minimally invasive procedure. Mesh infection is one of the challenging complications after TEP inguinal hernia repair. However, the cases of delayed asymptomatic mesh infection caused by hernia mesh is extremely rare. This report aims to reveal that the risk of mesh infection may occur after a long period of this surgery. This report is also intended to suggest surgeons pay more attention to the follow-up of such patients and to be aware of the possibility of asymptomatic mesh infection to assist in early diagnosis and treatment.Case presentation: A 63-year-old male patient, who underwent TEP inguinal hernia repair 6 years ago for right inguinal hernia, fell down accidentally 2 weeks ago. Enhanced computed tomography(CT) showed lower right abdomen space-occupying lesions. So he underwent laparoscopic surgery during which abscess caused by delayed mesh infection was found. After removing the mesh and abscess, he was discharged. Conclusion: The risk of mesh infection after TEP inguinal hernia repair is low, but it can last for more than 6 years and can even be asymptomatic as long as the mesh remains in the body.
