double breasting of the fascia transversalis in Shouldice Repair in Modalities of Repair in Principle of Herniorrhaphy in Steps in Operative in Surgical details of Surgical treatment in Treatment of Oblique inguinal hernia
- The fascia transversalis is opened in the length of the floor of inguinal canal from the pubic tubercle to the internal ring; this creates 2 flaps.
- The lower flap is sutured to the undersurface of the upper flap.
- The upper flap is sutured to the shelving edge of the inguinal ligament
- Finally the fascial part of the conjoint tendon is sutured to the inguinal ligament.
