BACKGROUND Routine contralateral inguinal exploration following unilateral herniorrhaphy in children remains controversial. Contralateral patent processus vaginalis (PPV) incidence decreases from 80% in young infants to about 20% to 30% in the adult population. However, the incidence of a clinical hernia appearing subsequently following unilateral herniorrhaphy is 6% to 10%. METHODS Fifty consecutive children were evaluated by diagnostic laparoscopy (DL) at the time of inguinal herniorrhaphy. RESULTS The mean age was 3 years. Thirteen of 42 patients (31%) with a symptomatic confirmed hernia had a contralateral PPV by DL. The mean operating time was 48 minutes. The sensitivity was 98% with a specificity of 100%. No child suffered a complication due to DL. CONCLUSIONS We found diagnostic laparoscopy in children with evidence of unilateral inguinal hernia (1) was safe, (2) revealed a 31% incidence of contralateral PPV, and (3) eliminated the need for contralateral exploration in 69%.

D006552	Hernia, Inguinal	An abdominal hernia with an external bulge in the GROIN region. It can be classified by the location of herniation. Indirect inguinal hernias occur through the internal inguinal ring. Direct inguinal hernias occur through defects in the ABDOMINAL WALL (transversalis fascia) in Hesselbach's triangle. The former type is commonly seen in children and young adults; the latter in adults.
