title: Lichtenstein repair of indirect inguinal hernias with acellular tissue matrix grafts in adolescent patients: a prospective, randomized, controlled trial.
abstract: OBJECTIVE
  To evaluate the outcomes of Lichtenstein hernioplasty using acellular tissue matrix (ACTM) grafts in adolescent patients.
  
  
  METHODS
  One hundred patients, 13-18 years old, with primary unilateral indirect inguinal hernias, were randomly assigned to receive Lichtenstein hernioplasty using ACTM or traditional high ligation of the hernia sac (control group).The outcome measures were the length of the operation, postoperative visual analogue scale (VAS) pain score, length of hospitalization, postoperative complications and recurrence rate.
  
  
  RESULTS
  The length of hospitalization and VAS score were not different between the groups, and the minimum follow-up was 30 months. No postoperative wound infections, chronic postoperative pain or local foreign body sensation occurred in either group. Six patients (14.3 %) in the experimental group and five (11.6 %) in the control group developed scrotal hydroceles (P > 0.05); all resolved with conservative management. There were no recurrences in the experimental group, while there were three (6 %) in the control group (P > 0.05) and all occurred in patients with Gilbert type 3 hernias.
  
  
  CONCLUSIONS
  Lichtenstein hernioplasty using ACTM grafts has comparable safety and efficacy to traditional high ligation of the indirect hernia sac in adolescent patients. ACTM can reduce the incidence of recurrence in adolescents with Gilbert type 3 hernias.
