Kurobe M, Baba Y, Otsuka M. Inguinal hernia in very low-birthweight infants: Follow up to adolescence. Pediatr Int 2016; 58:1322-1327. [PMID: 27285670 DOI: 10.1111/ped.13060] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/23/2014] [Revised: 03/04/2016] [Accepted: 04/25/2016] [Indexed: 11/30/2022]
Abstract
BACKGROUND This study reviewed the medical records of very low-birthweight infants (VLBWI) followed up to adolescence, with emphasis on inguinal hernia (IH), to discuss the ideal time for IH repair in VLBWI. METHODS Medical records from 274 VLBWI treated in the neonatal intensive care unit (NICU) between 1994 and 1999 were collected retrospectively. Outpatient data after NICU discharge were included. Additionally, a follow-up study was undertaken via questionnaire sent to the families of VLBWI in 2011. RESULTS During NICU hospitalization, IH was diagnosed in 39 of 274 VLBWI, and two developed incarceration. Thirty-eight VLBWI were discharged with known hernia, and elective repair was performed in 19. Three developed incarceration before elective repair at the mean age of 316 days. In the remaining 18 cases of IH, spontaneous regression occurred at a mean age of 180 days and repair was not performed. New IH appeared in 25 VLBWI after NICU discharge. CONCLUSIONS The high incidence of IH in VLBWI was confirmed during follow up to adolescence. The rate of incarceration was low and the incidence of spontaneous regression was high. Observation up to 6 months without surgery, with the expectation of spontaneous regression, is one option to avoid unnecessary surgery, but repair should be performed before 10 months to reduce the risk of incarceration. Further large, prospective, and randomized controlled studies with a long follow up are necessary to validate the present results and to define the ideal time for IH repair in VLBWI.

Hutson JM, Kearsey I. Is the ovary in an inguinal hernia 'descended' like a testis or not? J Pediatr Surg 2016; 51:1197-200. [PMID: 26463501 DOI: 10.1016/j.jpedsurg.2015.09.014] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/03/2015] [Revised: 09/10/2015] [Accepted: 09/10/2015] [Indexed: 10/23/2022]
Abstract
BACKGROUND/AIM How testes descend through the inguinal canal is well described, but how the ovaries appear inside an inguinal hernia remains controversial. We reviewed the literature to determine whether ovarian 'descent' has been described. METHODS The English literature from 1950 to 2014 was reviewed via PubMed, Medline and Web of Science to identify papers describing an ovary in the hernia sac: reports were examined to find whether the ovary prolapsed or 'descended', and the anatomy of its supporting ligaments, cranial suspensory ligament (CSL) and round ligament (female gubernaculum, RL). RESULTS In forty reports of >7140 inguinal herniotomies and/or imaging studies in females the hernia contains an ovary in 15-20%, often with the ipsilateral fallopian tube. The RL and ovary were aligned along the same path as testicular descent only rarely in Müllerian anomalies with an isolated uterine horn preceding the ovary into the sac. The ligament usually found inside the hernia sac was the CSL, not the RL. DISCUSSION The high frequency of incarcerated ovary, along with the close proximity of the CSL to the internal ring in females is consistent with a sliding hernia pulling the CSL (and ovary) into the hernia sac, not ovarian 'descent' by traction on the RL.

Abstract
BACKGROUND/PURPOSE This study provides epidemiologic data on the incidence of inguinal hernia repair in preschool children using the Taiwan National Health Insurance Research Database. We believe that the data on hernia repair in said database provide a close approximation of the true incidence of inguinal hernia in young children. METHOD A cohort of 1,073,891 deidentified individuals was randomly selected from an insured population of 23 million. Subjects born during the period 1997-2004 were followed from birth to 6 years. The chi-square test and logistic regression modeling were used for statistical analyses. RESULT A total of 92,308 individuals were born during the study period. Of these individuals, 3881 underwent hernia repairs. The cumulative incidence of hernia repair in children aged 0 to 6 years was 4.20%/7 years. The boy/girl ratio was 4.27:1 and the unilateral/bilateral ratio was 3.77:1. The incidence of hernia repair among boys was highest during the first year of life, but then decreased with age. In contrast, the incidence among girls remained stable during the first 6 years of life. Boys younger than 1 year had more bilateral repairs than boys in other age groups (p<0.0001) and girls had significantly more bilateral repairs than boys (p<0.0001). Subjects with a history of preterm birth also had a higher incidence of hernia repair than subjects who were born at full term (odds ratio=2.34, p<0.0001). CONCLUSION Yearly incidence of hernia repair was obtained from a nationwide database. Some of the observations have not been reported elsewhere.

Abstract
BACKGROUND/PURPOSE Operations for the treatment of inguinal diseases are the most frequent in childhood. Bleeding owing to trauma to the spermatic vessels is frequent and can cause testicular atrophy. The goal of this work was to determine the effects of the trauma to the spermatic vessels in the prepubertal and postpubertal histopathologic alterations in an experimental model in Wistar rats. METHODS Eighty albino Wistar rats were divided in 4 groups for the histopathologic analysis. In group A, they were submitted to digital compression of the spermatic vessels for 45 seconds; in group B, the spermatic vessels were clamped with hemostats for 5 seconds; in group C, the spermatic vessels were cauterized for 2 seconds. Group D was the control group, in which the animals were submitted to inguinotomy solely. RESULTS The prepubertal histopathologic alterations were significantly decreased in group A for testicular weight (0.97 +/- 0.10); in group B, for testicular weight (0.81 +/- 0.24), testicular volume (0.522 +/- 0.192), and mean testicular biopsy score (7.2 +/- 2.7); and in group C, for the 5 parameters studied, testicular weight (0.69 +/- 0.28), testicular weight per 100 g of body weight (0.498 +/- 0.188), testicular volume (0.765 +/- 0.308), mean seminiferous tubular diameter (236.6 +/- 62.5), and mean testicular biopsy score (6.9 +/- 3.1). The postpubertal histopathologic alterations were not significant for any of the 5 parameters studied, in the 3 groups. CONCLUSIONS The prepubertal histopathologic alterations were more intense in the group submitted to cauterization of the spermatic vessels, intermediate in the group submitted to clamping of the spermatic vessels with hemostats, and less severe in the rats submitted to digital compression of the spermatic vessels. The postpubertal histopathologic alterations demonstrated the capability of the young testicle to recuperate from a vascular trauma.

Abstract
Apart from higher rates of mortality and adverse neurosensory outcome, extremely low birth weight (ELBW, birth weight 500-999 g) children have more hospital readmissions and other health problems in the early years after discharge than do normal birth weight (NBW, birth weight >2499 g) children. Respiratory illnesses, including lower respiratory infections, are the dominant cause for hospital readmission. ELBW survivors with bronchopulmonary dysplasia (BPD) have even more ill-health and hospital readmissions than do ELBW survivors without BPD. ELBW survivors require closer surveillance after discharge, not only for adverse neurosensory outcome, but also for other general health problems in early childhood.

Abstract
Inguinal hernia repair is one of the most common surgical procedures performed on premature infants. Improved survival rates in the NICU have led to an increase in the incidence of premature infants with inguinal hernias. The NICU nurse, often the first to notice an inguinal hernia in a premature infant, should understand the etiology, basic pathophysiology, and nursing care for this condition.

Abstract
PURPOSE This is a prospective study of 8 clinically apparent inguinal hernias in 7 preterm infant girls. METHODS The diagnosis was made clinically and confirmed by ultrasonography, which also showed the contents of the hernia. RESULTS One hernia contained an ovary, the other 7 intestinal loops. The hernias with only intestinal loops regressed spontaneously when the girls were between the ages of 2 and 6 months postpartum. This was confirmed by ultrasonography. At follow-up 2 to 6 years later there has been no recurrence. The hernia that contained the ovary did not regress, and hernia repair (confirming the presence of the ovary) was carried out uneventfully. CONCLUSIONS The authors suggest that preterm infant girls with an inguinal hernia should have ultrasonography performed at presentation. Surgery probably will be required when the hernia contains structures such as an ovary. When the hernia contains only intestinal loops an expectant policy may be advisable. Larger studies are needed to validate these findings.

Abstract
Inguinal hernias were diagnosed at 42 and 38 weeks' postconceptional age in 2 premature girls. The hernial sac contained the uterus, one Fallopian tube, and one ovary. The diagnosis was made by physical and sonographic examination and was confirmed during surgical correction. We suggest sonography in the diagnostic workup in (premature) female infants with an inguinal hernia.

Abstract
OBJECTIVE To analyse hospital readmissions to 1 year in infants < 33 weeks' gestation. STUDY DESIGN Cohort of very preterm infants born in Western Australia. METHODS Parental social class, history of asthma, race, gestational age, birthweight, sex, severity of respiratory disease and oxygen requirement at 28 days chronic lung disease (CLD), 36 weeks and term, maternal smoking, cohabitation with siblings, breast-feeding duration and hospital readmissions were recorded prospectively. RESULTS Data were available for 538 of 560 (96%) infants discharged. Eight died in the first year. Two hundred and twenty-five infants (42%) had 443 readmissions, of which 370 were medical and 73 surgical. Risk factors for medical readmission were Aboriginal race, male sex and CLD. Breast-feeding was protective. Risk factors for surgical admission were male sex, lower gestation, severe hyaline membrane disease, severe CLD and birthweight < 10th centile. CONCLUSIONS Readmission is common after very preterm birth. Risk factors for medical and surgical admission differ with CLD being the only perinatal factor associated with both medical and surgical admission.

Abstract
The prevalence of inguinal hernia during primary hospitalization was determined in 250 infants with gestational age 24-29 weeks. Fourteen per cent developed hernia, with prevalence significantly higher in boys than girls. Infants with respiratory distress syndrome and those requiring prolonged mechanical ventilation were significantly predisposed to the development of hernia. Male infants, especially those who required prolonged ventilatory assistance, were at greatest risk. This information may be used when counselling parents regarding complications of very preterm infants.

Abstract
This chapter outlines some of the many long-term health problems to be expected in surviving preterm children. They have higher rates of sensorineural impairments (such as cerebral palsy, and visual, auditory and intellectual impairments) and sensorineural disabilities from these impairments, than children born at term. In addition, they grow poorly and have higher rates of other health problems, including poorer respiratory health in early childhood. There is little doubt that preterm children contribute disproportionately to the prevalence of health problems in childhood. However, there are still many gaps in our knowledge of the outcome for preterm survivors, particularly regarding outcome in adulthood. Obstetricians and neonatologists working in intensive care, as well as parents, want to know the long-term outcome for preterm children born today, not that of children born a generation ago when fewer preterm children (particularly those of extremely low birthweight) survived. Despite the many problems, the conclusion is that most preterm children are as healthy as term children, suffering only usual childhood illnesses; we feel confident that the majority make, and will continue to make, useful contributions to their families and the societies in which they live.
