Prematurity, not age at operation or incarceration, impacts complication rates of inguinal hernia repair

PurposeInguinal hernia repair (IHR) remains the most common procedure in pediatric surgery. Although postoperative sequelae are well described, we examined if prematurity and age were important determinants of postoperative complications.MethodsA retrospective review of children younger than 2 years undergoing IHR from 2004 to 2007 was performed, with a minimum of 1-year follow-up. Patients were segregated into groups based on age at diagnosis (A, 0-3; B: 4-26; C: 27-52; D: 53-104 weeks), with or without prematurity. Incarceration rates were investigated. Complications were categorized as major (vas injury, recurrence, testicular atrophy) or minor (wound infection, “high” testicle, hydrocele) and compared.ResultsTwo hundred sixty-eight patients were analyzed (98 premature), with 14 major complications (5.2%) and 26 (9.7%) minor complications overall. Groups A and B accounted for more major (12/14) and minor complications (22/26) when compared with groups C and D (P < .005). In patients less than 26 weeks (groups A and B), premature infants had more complications than term infants (27.7% vs 12.1%, P = .01). Of 22 patients with incarcerated hernias, 2 (9.1%) had major complications (P < .5 vs nonincarcerated patients).ConclusionsOur study suggests that prematurity, rather than age at operation or incarceration, affects complication rates after IHR. This information should be used to frame the discussion of informed consent for this commonly performed procedure.
