SURGERY • ABDOMINAL WALL

A 38-year-old multiparous woman presents with a painless swelling in the right groin that becomes prominent on standing and coughing. On examination, the swelling is above the inguinal ligament, reducible, and has a positive cough impulse.

Which of the following is the most common type of hernia in females?

A Direct inguinal hernia

B Femoral hernia

C Indirect inguinal hernia

D Incisional hernia

E Obturator hernia

Indirect inguinal hernias are the most common type of hernia in both sexes. While femoral hernias are more common in women than in men, they are still less frequent than inguinal hernias in the female population overall.

Decoding Clue

1

CLUE "Swelling above the inguinal ligament"

TRANS This anatomically distinguishes an Inguinal hernia from a Femoral hernia (which presents below the ligament).

2

CLUE "Most common type in females"

TRANS This is a classic "exam trap." Students often pick femoral because it's more common in women *relative to men*, but indirect inguinal remains #1 in absolute numbers.

Differential Breakdown

A. Direct Inguinal: Occurs through Hesselbach’s triangle. It is rare in women due to the narrower inguinal canal compared to men.

B. Femoral Hernia: Common in females but NOT the most common overall. It has the highest risk of strangulation and is located below the inguinal ligament.

D. Incisional Hernia: Occurs at sites of prior surgical incisions. No history of surgery was provided in the vignette.

E. Obturator Hernia: Extremely rare. Typically seen in "skinny elderly ladies." Key sign is pain on the medial thigh (Howship-Romberg sign).
