The Lichtenstein tension-free mesh repair for inguinal hernia uses which anatomical structure as the floor of the repair?
- A A flat polypropylene mesh sutured to the inguinal ligament below and internal oblique above ✓
- B Conjoint tendon and inguinal ligament
- C Cooper's ligament and pectineal muscle
- D Transversalis fascia and peritoneum
Correct answer: A. A flat polypropylene mesh sutured to the inguinal ligament below and internal oblique above
Explanation
The Lichtenstein repair places a flat polypropylene mesh to reinforce the posterior wall of the inguinal canal without tension; the mesh is sutured inferiorly to the inguinal ligament and superiorly to the conjoint tendon and internal oblique aponeurosis, with a slit created for the spermatic cord. It is the most widely performed open hernia repair worldwide with a very low recurrence rate. The absence of tissue tension distinguishes it from older repairs such as Bassini or Shouldice.
