A 48-year-old man presents to the surgical outpatient department with a painless swelling in the right groin for 3 months. On examination, the swelling is reducible, and a cough impulse is present. The swelling lies below and lateral to the pubic tubercle. Which of the following is the most likely diagnosis and the recommended management?

Explanation

## Diagnosis: Femoral Hernia The clinical presentation is classic for a **femoral hernia** based on the anatomical location of the swelling. ### Key Anatomical Landmark **Key Point:** The relationship to the pubic tubercle is the single most important clinical sign for differentiating groin hernias: - **Inguinal hernia** (direct and indirect): swelling lies **above and medial** to the pubic tubercle - **Femoral hernia**: swelling lies **below and lateral** to the pubic tubercle In this case, the swelling is **below and lateral** to the pubic tubercle — this is **pathognomonic for a femoral hernia**. The original explanation incorrectly dismissed this landmark finding and misclassified the hernia as indirect inguinal. ### Femoral Hernia: Key Features | Feature | Femoral Hernia | |---------|----------------| | **Location** | Below and lateral to pubic tubercle | | **Canal** | Passes through femoral canal, medial to femoral vein | | **Sex predilection** | More common in females (but occurs in males) | | **Cough impulse** | May be present (as in this case) | | **Reducibility** | Can be reducible initially | | **Risk of strangulation** | **Very high** (~40% present with strangulation) | **Clinical Pearl:** A femoral hernia has the **highest risk of strangulation** among all groin hernias due to the rigid boundaries of the femoral ring (inguinal ligament anteriorly, lacunar ligament medially, femoral vein laterally, pectineal ligament posteriorly). Even a reducible femoral hernia warrants prompt elective repair. ### Management **High-Yield:** All femoral hernias, once diagnosed, should undergo **elective surgical repair** because: 1. The risk of incarceration and strangulation is extremely high (~40% lifetime risk). 2. Emergency repair carries significantly higher morbidity and mortality than elective repair. 3. Watchful waiting is **contraindicated** for femoral hernias. Recommended surgical techniques include: - **McVay (Cooper's ligament) repair** — classic open technique for femoral hernias - **Mesh plug repair** or **Lichtenstein-type mesh repair** - **Laparoscopic TEP/TAPP** — increasingly preferred **Emergency surgery** (Option C) is reserved for incarcerated or strangulated femoral hernias presenting with signs of bowel obstruction or peritonitis. This patient has a reducible hernia with no signs of strangulation, so **elective repair** is appropriate. ### Why Indirect Inguinal Hernia Is Incorrect An indirect inguinal hernia emerges through the deep inguinal ring and lies **above and medial** to the pubic tubercle. The anatomical location described in this stem (below and lateral to the pubic tubercle) definitively excludes an inguinal hernia. ## Summary The correct answer is **femoral hernia with elective surgical repair (McVay or mesh technique)** because: - The swelling below and lateral to the pubic tubercle is pathognomonic for a femoral hernia. - All femoral hernias require elective repair due to the very high risk of strangulation. - The patient is currently reducible (no emergency indication), making elective repair the appropriate choice.
