Is contralateral exploration necessary in infants with unilateral inguinal hernia?
Between 1973 and 1985, 165 infants (aged 1 week to 6 months) underwent unilateral inguinal herniotomy at our hospital. An attempt was made to trace these 165 children. It proved possible to contact and examine 116 children (104 boys and 12 girls). Age at follow-up ranged from 5 to 17 years. Parents were asked whether their children had attended any hospital for the treatment of contralateral hernia. All children were examined for the evidence of contralateral hernia. Boys were also examined for the position and size of the testis. Testicular volume was assessed with the help of Prader's Orchidometer. Twelve children (10.3%), 11 boys and 1 girl, subsequently developed contralateral inguinal hernia. The mean time interval between initial hernia operation and subsequent development of contralateral hernia was 164 days (range, 7 days to 18 months). Diminished size of testes was observed on the side of the operation in six patients and one patient had complete testicular atrophy. Three boys had a testis in the groin, presumably hitched up at operation and all three required orchidopexy. In view of the relatively low incidence of contralateral hernia and increased risk of damage to testes, we feel that routine contralateral exploration is not justified.
