According to the Gilbert classification of groin hernias, which type describes a small direct hernia with a small, well-defined defect in Hesselbach's triangle, sometimes called a diverticular outpouching of the transversalis fascia?

• A Type II
• B Type III
• C Type IV
• D Type V ✓

Explanation

In the Gilbert system, types I to III are indirect hernias of increasing size, type IV is a large direct hernia with a diffuse bulge of the posterior wall, and type V is a small direct hernia with a discrete, diverticular defect in the transversalis fascia. Types VI and VII were added later for pantaloon and femoral hernias respectively. Confusing type IV with type V is the classic error: type IV is a large diffuse direct bulge, whereas type V is a small punched-out direct defect.
