Study Notes
- Successful hernia repair relies on tension-free closure of the defect for minimal recurrence rates.
- Earlier methods of simply suturing the defect resulted in recurrence rates as high as 15%.
- Current techniques involve placing mesh over or behind the hernia defect to enhance repair.
- The Shouldice repair is an exception, achieving low recurrence rates through careful dissection and closure without mesh.
- Tension-free closure leads to reduced postoperative pain and discomfort.
Open Inguinal Hernia Repair
- Begins with a 6-8 cm transverse, slightly curved skin incision, positioned one to two fingerbreadths above the inguinal ligament.
- Dissection proceeds through the subcutaneous and Scarpa’s layers.
- The external oblique aponeurosis is identified, with the external ring located inferomedially.
- The aponeurosis is carefully incised and opened along its length through the external ring using fine scissors, while avoiding nerve injury.
- The iliohypogastric and ilioinguinal nerves are identified and preserved without mobilization to prevent post-herniorraphy inguinodynia.
- The genital branch of the genitofemoral nerve should be identified and preserved without mobilization in order to retain their protective investing fascial layers.
- Soft tissue is cleared from the posterior surface of the external oblique aponeurosis on both sides, and the spermatic cord is mobilized.
- The cremaster muscle fibers are separated from the cord structures using blunt and sharp dissection to isolate the cord.
Hernia Anatomy
- An indirect hernia presents with a sac attached to the cord in an anteromedial location, extending superiorly through the internal ring.
- A direct inguinal hernia appears as a weakness in the floor of the canal, posterior to the cord.
- A pantaloon defect involves both direct and indirect defects within the same inguinal canal.
