Background This study reviewed the medical records of very low‐birthweight infants (VLBWI) followed up to adolescence, with emphasis on inguinal hernia (IH), to discuss the ideal time for IH repair in VLBWI. Methods Medical records from 274 VLBWI treated in the neonatal intensive care unit (NICU) between 1994 and 1999 were collected retrospectively. Outpatient data after NICU discharge were included. Additionally, a follow‐up study was undertaken via questionnaire sent to the families of VLBWI in 2011. Results During NICU hospitalization, IH was diagnosed in 39 of 274 VLBWI, and two developed incarceration. Thirty‐eight VLBWI were discharged with known hernia, and elective repair was performed in 19. Three developed incarceration before elective repair at the mean age of 316 days. In the remaining 18 cases of IH, spontaneous regression occurred at a mean age of 180 days and repair was not performed. New IH appeared in 25 VLBWI after NICU discharge. Conclusions The high incidence of IH in VLBWI was confirmed during follow up to adolescence. The rate of incarceration was low and the incidence of spontaneous regression was high. Observation up to 6 months without surgery, with the expectation of spontaneous regression, is one option to avoid unnecessary surgery, but repair should be performed before 10 months to reduce the risk of incarceration. Further large, prospective, and randomized controlled studies with a long follow up are necessary to validate the present results and to define the ideal time for IH repair in VLBWI.
