Complications while awaiting elective inguinal hernia repair in infants: Not as common as you thought

Abstract

Background: The dogma of early inguinal hernia repair in infants, especially those born prematurely, has dominated clinical practice owing to reports of a high frequency of incarceration and significant complications associated with untreated inguinal hernias. We aim to evaluate the frequency of complications after discharge with delayed surgery for inguinal hernia repair. Methods: The Nationwide Readmissions Database (2010–2014) was queried to identify infants diagnosed with inguinal hernia. We compared the frequency and characteristics of inguinal hernia repair performed during the index admission, discharge from the index admission without hernia repair, and unplanned readmissions. Results: We identified 33,530 infants (16,624 preterm and 16,906 full-term) diagnosed with an inguinal hernia during an index admission. For those infants diagnosed with an inguinal hernia at birth, inguinal hernia repair was performed during the birth admission for only a minority of both preterm (35%) and full-term infants (18%; P
