INTRODUCTION: The aim of this study was to analyze the gender-related differences of inguinal hernia (IH) and patent processus vaginalis (PPV) in term and preterm infants.
METHODS: Over a nine-year-period 411 infants underwent laparoscopic herniorrhaphy within the first six months of life. 246 term (191 male; 55 female) and 165 preterm (118 male; 47 female) infants were included in this retrospective study. Initial presentation of IH and intraoperative anatomical findings of PPV were reviewed.
RESULTS: We found that term boys (58.6%) and girls (58.2%) predominantly presented with right-sided IH whereas preterm boys (36.4%) and girls (44.7%) mostly presented with bilateral IH. Female babies had a higher incidence of initial left-sided IH. Term and preterm girls with initial left-sided hernia were found to have highest incidence of PPV. Male term babies with initial left-sided IH were found to have the lowest incidence of PPV (25.0%). The highest incidence of PPV in male was found in preterm boys with either left- or right-sided IH.
CONCLUSION: Incidence and laterality of IH and PPV differ between term and preterm girls and boys. In open hernia repair decision concerning contralateral groin exploration should consider term/preterm birth as well as gender.
