Transperitoneal closure of the internal ring in incarcerated infantile inguinal hernias.

Over a 6-year period, 14 infants with a total of 16 inguinal hernias (IH) underwent transperitoneal closure of the internal ring (TPIR). This was performed through a minilaparotomy, using a purse-string suture placed around the internal ring from within. A difficult inguinal dissection of an edematous and friable spermatic cord was avoided. TPIR was performed for incarceration in 13 of the infants and for recurrence of the hernia within 24 hours of herniotomy in one. There were no intraoperative problems, and during follow-up there was no evidence of testicular atrophy or recurrence of the hernia. This suggests that TPIR is a reliable and safe operation in babies for whom the alternative inguinal approach would be difficult. These situations include hernias that are irreducible and early recurrence in which dissection of the cord would risk damage to the vas deferens or testicular vessels.
