“…Thus, they recommended herniorrhaphy during NICU admission, especially in VLBW infants, who have a high risk of incarceration while waiting for operation. By contrast, the incidence of incarceration was not different between preterm and term infants, and was low in both groups according to a nationwide survey in Taiwan (0.43% in preterm infants vs. 0.41 % in term infants, P=0.959) 20) . Relatively few incarcerations were reported in the present study.…”

Purpose: The objective of this study was to determine the optimal timing of inguinal herniorrhaphy in preterm infants to reduce the risks of preoperative incarceration and postoperative complications. Methods: Preterm infants with gestational age (GA) of <37 weeks who had ingui nal herniorrhaphy before the age of 6 months were enrolled. Early repair was defined as undergoing herniorrhaphy before discharge from the neonatal intensive care unit (NICU), and late repair was defined as undergoing herniorrhaphy as an outpatient after discharge from the NICU. Results: The incidence rates of preoperative incarceration and recurrence were not significantly different between the two groups. Postoperative apnea and mechanical ventilation were more frequent in the early-repair group than in the late-repair group. Postoperative apnea was more frequent in the early-repair group after adjustments for GA and birth weight. However, no significant difference in postoperative mechanical ventilation was found between the two groups after adjustments for GA and birth weight. The incidence of postoperative apnea was associated with small weight at repair, early repair, general anesthesia, younger GA, small weight at birth, and bronchopul monary dysplasia. Contralateral metachronous hernia was most frequent in infants with small weight at repair, early repair, very low birth weight (VLBW), male sex, and right-sided hernia. Conclusion: Late repair was safe and did not increase the risk of incarceration or recurrence, but decreased the risks of postoperative apnea and metachronous hernia. Regional anesthesia could reduce the risk of postoperative apnea. Male infants born with VLBWs and right-sided hernia should be followed up carefully for metachronous hernia.

“…Because obliteration of the processus vaginalis begins during gestation, canal of Nuck and other inguinal hernias are associated with prematurity and may occur in 9%–11% of infants born prematurely (7). A study of 92,308 children found that inguinal hernias may be associated with lung disease and mechanical ventilation, which may be explained by the increase in intraabdominal pressure present in these situations (8).…”

The canal of Nuck, caused by the failed closure of the processus vaginalis in the female, is the continued outpouching of parietal peritoneum through the inguinal canal to the labia majora. Disorders of the canal of Nuck include hernia and hydrocele. Some canal of Nuck hernias, especially of the ovary, may result in emergent complications such as incarceration, strangulation, and ovarian torsion. Knowledge of canal of Nuck disorders and prompt diagnosis are important to avoid serious complications. Imaging, especially ultrasound, is essential for timely diagnosis, leading to appropriate management and better patient care.

Partial or complete failure of obliteration of the processus vaginalis in the female results in the formation of a potential space known as the canal of Nuck, into which various organs and/or collections can herniate. A 4-month-old female presented with a left labial mass related to herniation of the uterus, ovaries and fallopian tubes through the canal of Nuck. Early diagnosis is important as there is a high risk of ovarian torsion and incarceration.

Abstract: Birth weight under 2500 g is a significant risk factor for IH repairs. Other risk factors are male gender, past history of lung diseases, and ventilator supports.
