Congenital Inguinal Hernia clinical trials

Needlescopic Inversion and Snaring Versus Ligation of Hernia Sac in Girls

Failure of closure of the processus vaginalis during intrauterine life will result in congenital inguinal hernia [CIH]. Exact incidence of CIH in children is not known but it has been reported between 1-5 %. In premature babies, the incidence may reach up to 15-30%. Congenital inguinal hernia is more common in boys than girls, ranging from 4:1 to 10:1 [1]. Although the open inguinal herniotomy and high ligation of the sac is the gold standard line of the treatment, Laparoscopic inguinal hernia repair become a good option. The laparoscopy has many advantages that it is simple, feasible, and safe with detection of the contralateral hernia and other hernias. In addition to laparoscopy results in excellent cosmetic results low wound infection, less pain, and short hospital stay. The non-division of the hernia sac in during laparoscopic hernia repair may be the cause of recurrence and postoperative hydrocele [5]. Division of hernia sac and suturing of proximal part at IIR; is modification of the laparoscopic technique which mimic what happen during open herniotomy. Some authors resected the processus vaginalis and closed the inguinal ring for the repair of CIH. They claimed that they have excellent results with low recurrence.One author described a technique based on the theory that CIH is due to a patent processus vaginalis, and therefore, the procedure should be to entirely resect it, with or without closure of the internal ring. This allows the peritoneal scar tissue to close the area of the ring. Also, this scarring occurs in the extent of the inguinal canal where the dissection took place, therefore causing the same peritoneal scarring and sealing of the inguinal floor with complete resolution of the problem. However, a few studies address the superiority of technique over the other and to date there is no controlled randomized study to compare needlescopic disconnection of the hernia sac and closure of the peritoneum at IIR versus disconnection without closure of the peritoneum.
