Abstract
INTRODUCTION: A De Garengeot hernia is a rare form of femoral hernia, where the appendix is found in the herniated sac. This feature is important to report, as both the diagnosis and the treatment are quite challenging in this particular condition. PRESENTATION OF CASE: We report the case of a 77-year-old female presenting with a femoral hernia, containing an incarcerated necrotic vermiform appendix (De Garengeot hernia). A laparoscopic appendectomy was performed and the herniated defect was repaired according to Rives technique, using a biological mesh. DISCUSSION: The De Garengeot hernia is often unexpected and diagnosed intra-operatively. A pre-operative diagnosis is quite difficult, as it often presents clinically as a strangled femoral hernia. In patients without peritoneal signs, a contrast-enhanced Computed Tomography (CT) of the abdomen is useful for the diagnosis. Many surgical techniques have been discussed in literature, but there is no consensus. We show the feasibility and safety of the hernia repair according to Rives technique, through an inguinotomy with a biologic mesh. A laparoscopic approach was used to remove the necrotic appendix. CONCLUSION: The De Garengeot hernia is an uncommon differential diagnosis for patients presenting with clinical signs of strangled femoral hernia. Although hernia repairs with a synthetic mesh in the presence of appendicitis have been reported, we describe a case of femoral hernia repair using a biologic mesh, in a patient with a De Garengot hernia.
