Laparoscopic surgery for De Garengeot's hernia in a man after inguinal hernia surgery with a mesh plug: a case report and review of literature.

Background: De Garengeot's hernia is a rare case of a femoral hernia that contains the appendix. Here we report a case of De Garengeot's hernia that occurred in a male patient who had a history of inguinal hernia surgery using a mesh plug. There were no reports of De Garengeot's hernia with a history of surgery for inguinal hernia, and the surgical question was whether we could successfully treat a patient with minimally invasive laparoscopic surgery using a mesh.

Case presentation: This case involved 75-year-old man with a history of right indirect inguinal hernia surgery using a mesh plug without on-lay mesh, who presented with a 5-day history of a right groin lump. Abdominal CT revealed an incarcerated appendix within the right femoral hernia and fluid collection around the appendix. Laparoscopic surgery was initiated and the incarcerated appendix was released with traction. There was no contamination around the appendix or the femoral ring, the appendix was removed, and the femoral hernia was repaired using mesh. Laparoscopic surgery was useful in first evaluating the inflammatory status of the appendix. As it was determined that there was little inflammation around the appendix and femoral ring, it was possible to repair the hernia using mesh.

Conclusions: De Garengeot's hernias are rare and there is currently no standardized approach. Even if it is a recurrent hernia in the groin, laparoscopic surgery can be useful for diagnosis and treatment, but the use of mesh requires further careful consideration.
