In the TEP (totally extraperitoneal) laparoscopic inguinal hernia repair, the mesh is placed in the preperitoneal space and must cover the entire myopectineal orifice of Fruchaud. The triangle of doom in laparoscopic hernia repair contains:

• A Inferior epigastric vessels
• B Lateral femoral cutaneous nerve
• C External iliac vessels and femoral nerve ✓
• D Genitofemoral nerve genital branch

Explanation

The triangle of doom in laparoscopic inguinal hernia repair is bounded medially by the vas deferens, laterally by the gonadal vessels, and inferiorly by the peritoneal fold. Within this triangle lie the external iliac artery, external iliac vein, and femoral nerve. Dissection or stapling within this triangle can cause catastrophic vascular injury. The triangle of pain contains the femoral branch of the genitofemoral nerve and lateral femoral cutaneous nerve.
