[A rare type of hernia seen twice in our department].

Case reports: a 66-year-old woman was admitted to our Department due to a painful inguinal lump. During examinations an incarcerated femoral hernia was found with an inflamed vermiform appendix inside the hernial sac. Appendectomy and femoral hernioplasty was performed from inguinal approach. The patient was discharged home without complications. Pathological examinations of the specimen showed signs of acute appendicitis. A few weeks later a 76-year-old man with severe comorbidities was admitted to our unit due to painful gangraenous inguinal skin lesion. CT scan showed an incarcerated femoral hernia containing the appendix with subcutaneous abscess. Appendectomy, hernioplasty, and inguinal necrosectomy was performed from an inguinal and low median approach. Another operation was necessary due to postoperative obstruction and subcutaneous dehiscence. After intraabdominal adhaesiolysis and abdominal wall reconstruction negative pressure wound therapy was applied to the inguinal wound, the patient was discharged 22 days after the primary operation. Pathological examinations of the appendix showed low grade mucinous neoplasm. Discussion: The femoral hernia containing the appendix is called de Garengeot’s hernia and is one of the rarest types of inguinofemoral hernias. The clinicopathology of this type of hernia can cover a wide range of symptoms. The definitive preoperative diagnosis is relatively difficult to find without a CT-scan. The surgical approach and treatment depends on the manifestation, clinical findings and on the available equipment and the expertise of the surgeon
