Edel M Duggan studies the outcomes of surgical procedures performed on premature and newborn infants, with a particular focus on inguinal hernias. These are conditions where tissue pushes through a weak spot in the abdominal wall, which can be serious for infants. Duggan's research evaluates whether repairing these hernias before or after infants are discharged from the hospital leads to better health outcomes. This includes assessing complications like the risk of hernias becoming trapped, which can require more surgery.
Key findings
In a study of 2,030 infants, delayed inguinal hernia repair was associated with a higher rate of hernia incarceration compared to early repair.
Early repair was linked to a modestly higher reoperation rate within one year post-surgery, although the exact percentage was not specified.
The research indicates there is no clear best timing for surgery, with practices varying widely across hospitals without definitive evidence supporting one method as safer overall.

The findings show that there are significant risks for these infants and that the timing of the surgery can influence outcomes, but many of the studies had limitations because they were based on small numbers of patients and were not designed to provide strong evidence. There’s a larger trial happening now to better understand the best timing for repairs and improve safety for these vulnerable infants.
Who this helps: This helps premature infants undergoing hernia repair and their families.
Does timing of neonatal inguinal hernia repair affect outcomes?
2015
Journal of pediatric surgery
Sulkowski JP, Cooper JN, Duggan EM, Balci O, Anandalwar SP +5 more
Plain English Researchers compared outcomes for premature and newborn infants who had inguinal hernia repair done before hospital discharge versus after, across 2,030 patients at multiple children's hospitals. Delayed repair was associated with a higher risk of hernia becoming trapped (incarceration), while early repair was tied to a modestly higher reoperation rate within a year. There is no clear best timing, and current practice varies widely across hospitals without evidence that one approach is safer overall.
