Intra-operative identification of a De Garengeot hernia: a rare finding and discussion of operative approach.

The presence of an incarcerated vermiform appendix within a femoral hernia defect, a De Garengeot hernia, is distinctly different than an inguinal hernia containing the appendix, an Amyand hernia. The De Garengeot hernia is a rare finding with few reported cases. We present a 35-year-old female with a painful groin mass palpable below the inguinal ligament. An ultrasound of the groin revealed a thin-walled fluid collection medial to the femoral vessels. No additional imaging at the time was obtained. Intra-operatively, the patient was found to have her distal appendix incarcerated within the transected hernia sac thus altering the planned surgical procedure. We present a unique operative approach for managing a De Garengeot hernia.
