Surgery
A 68-year-old man has been advised to undergo surgical treatment for a left reducible inguinal hernia.
He is otherwise healthy. Which of the following is the most appropriate treatment?
Explanation
1. Core Concept: An inguinal hernia occurs when intra-abdominal contents (such as bowel or omentum) protrude through a weakness or defect in the abdominal wall musculature within the inguinal canal.
2. Clinical Presentation:
- A visible or palpable groin bulge that enlarges with standing, coughing, or Valsalva maneuvers.
- Dull ache, heaviness, or pain in the groin, especially after heavy lifting.
- Complications include incarceration (irreducible) and strangulation (ischemia, severe pain, bowel obstruction).
3. Diagnosis:
- First-line: Clinical examination (palpation of the defect and assessing the cough impulse).
- Gold Standard: Clinical diagnosis; dynamic Ultrasound or CT scan if the diagnosis is equivocal.
4. Management:
- Acute: Watchful waiting for asymptomatic/minimally symptomatic hernias. Manual reduction for incarcerated but non-strangulated hernias.
- Definitive: Surgical repair is the gold standard for symptomatic hernias. Tension-free mesh repair (such as the Lichtenstein open mesh repair or laparoscopic TAPP/TEP) is the standard of care due to lower recurrence rates compared to primary tissue repair.
