Abstract

Background Pediatric inguinal hernia, hydrocele, and cryptorchidism are common congenital anomalies affecting children, and require surgical intervention in some cases. The association between surgical treatment of these conditions and acquired inguinal hernia later in life is poorly understood. The aim of this cohort study was to examine the effect of groin surgery during childhood on the incidence and surgical outcome of inguinal hernia repair in adult life.

Materials and Methods Data from the Swedish Inpatient Register and the Swedish Hernia Register were cross-linked using the patient personal identity numbers. The incidence of inguinal hernia repair in patients 15 years or older in the study cohort, as well as postoperative complication rates, were compared with the expected incidence and complication rates extrapolated from the general Swedish population in 2014, stratifying for age and gender.

Results Note that 68,238 children aged 0 to 14 years were found to have undergone groin surgery between 1964 and 1998. The median follow-up time after an operation in the groin was 30.8 years (21.0–50.0). Of those, 1,118 were found to have undergone inguinal hernia repair as adults (> 15 years old) between 1992 and 2013. The incidence of inguinal hernia repair in the cohort was significantly higher than that expected (1.43 [1.33–1.53]), both for men (1.32 [1.25–1.41]) and women (4.30 [3.28–5.55]). The incidence was also increased in the subgroup of patients that had undergone more than one procedure during childhood. No significant impact on postoperative complication rate, reoperation rate, or operation time was identified.

Conclusion Individuals undergoing surgery in the groin during childhood are at increased risk for acquired inguinal hernia surgery later in life. Inguinal surgery during childhood did not affect the outcome of hernia repair in adult age.
