General Surgery · Hernia and abdominal wall: triangle of doom

Sample item

In laparoscopic groin anatomy, the triangle bounded medially by the vas deferens and laterally by the gonadal vessels is avoided when placing staples. Which structures lie within it?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

A. External iliac artery and vein

The triangle of doom has the vas deferens medially and the gonadal vessels laterally, and contains the external iliac artery and vein, along with the deep circumflex iliac vein. Staples placed here risk catastrophic vascular injury. The triangle of pain, lateral to the gonadal vessels, carries the nerves.

Option by option

  • A. External iliac artery and vein (correct)

    Correct. The external iliac vessels lie in the triangle bounded by the vas and gonadal vessels.

  • B. Ilioinguinal and iliohypogastric nerves

    The ilioinguinal and iliohypogastric nerves lie in the abdominal wall layers and are not intraperitoneal landmarks here.

  • C. Lateral femoral cutaneous and femoral nerves

    The lateral femoral cutaneous and femoral nerves lie in the lateral triangle of pain, not in this one.

  • D. Inferior epigastric vessels and vas deferens

    The inferior epigastric vessels run medial to the deep ring and the vas is a border, not an interior structure.
