A Descriptive Study of Incarcerated Inguinal Hernia in Preterm Infants in Neonatal Intensive Care Units: A 10-Year Single-Center Experience

  • 1Department of Surgery, Samsung Medical Center, Sungkyunkwan University School of Medicine, Seoul, Korea


The aim of our study was to provide informative data for surgically treated preterm infants with incarcerated inguinal hernia (IH) in the neonatal intensive care unit (NICU).
Medical records of 9 preterm infants in NICU who underwent IH repair before NICU discharge between January 2011 and June 2020 were reviewed. The definition of incarcerated IH used was irreducible IH even by pediatric surgeon regardless of the use of sedation. The incarceration rate was calculated and informative data for incarcerated IH patients were collected.
Of 237 IH patients, 9 were diagnosed with an incarcerated IH and underwent emergency repair. At diagnosis of IH, the median age, the median postmenstrual age, and the median body weight were 22 days, 29.7 weeks, and 1,090 g, respectively. The diagnosis interval from IH to incarceration was ranged from 6 to 51 days, and none of them died of surgical procedure-related complications. Strangulation occurred in 4 patients and was treated with small bowel resection and enterostomy.
This study provided informative data for incarcerated IH in preterm infants successfully treated surgically. Close observation is more necessary because the incarceration rate during observation of preterm infants with IH in the NICU is as high as 3.8%.
