Modified Marcy repair of large indirect inguinal hernia in infants and children.

Based on a review of operative notes of recurrent inguinal hernia cases from the authors' primary series, a surgical technique modified from the Marcy repair is described. With this technique, emphasis is placed on preservation of the intact internal spermatic fascia and reduction in the size of the internal inguinal ring. Through the inguinal approach, the sleeve-like extension of the internal spermatic fascia is incised longitudinally along the cord and up to the internal ring. The cord structures are dissected off the sac, and as much of the fascial tissue as possible is preserved intact. Both edges of the fascial defect are approximated with an unabsorbable suture; great care is taken to not penetrate the wall of the sac. The same suture is then used for high ligation, via a stay suture placed on the transversalis fascia on the other side of the neck, to reduce the size of the internal ring. The technique can be used in premature babies who have a flimsy, easily torn sac, and in some cases of giant hernia with a widely dilated internal inguinal ring, if the direct wall integrity remains adequate.
