77-year-old gentleman presented with a four-day history of a painful right sided irreducible groin swelling. Background of previous bilateral mesh inguinal hernia repair thirty years prior. Differential diagnosis- recurrent incarcerated inguinal hernia.


Emergency presentation with a painful right sided groin lump with history of previous inguinal hernia repair. Past medical history of AF on rivaroxaban, HTN and BPH. Patient systemically well with an irreducible lump in the right groin. CTAP showed recurrence of hernia in right inguinal region containing fat stranding and a 2cm-sized fluid-filled structure (suspected appendix). Taken to theatre the following day - oblique incision in right groin. Obvious femoral hernia identified. Haemorrhagic fluid and a necrotic appendix contained in hernia sac. Open appendicectomy performed through groin incision and femoral canal plicated using 2.0 prolene. No mesh used due to risk of contamination. Discharged day 2 post-op. Pathology confirmed acute appendicitis.


Extremely rare case presentation. Femoral hernias account for 3% of all hernias and De Garengeot hernias only 1% of all femoral hernias. Furthermore, De Garengeot hernia with acute appendicitis accounts for only 0.01% of femoral hernias and are much more common in females than males with a 4:1 ratio. Femoral hernias are fifteen times more common in patients who have undergone previous inguinal hernia repair with 33% of men and 4% of women with De Garengeot hernia having undergone previous right inguinal hernia repair. Difficult pre-operative diagnosis given rarity with only 30% of cases diagnosed on pre-operative imaging-initial diagnosis Amyand hernia on CT imaging.
