Fish consumption in early pregnancy and congenital gastrointestinal tract atresia in the Japan Environment and Children's Study.

Current evidence suggests that the aetiology of congenital gastrointestinal (GI) tract atresia is multifactorial, and not based solely on genetic factors. However, there are no established modifiable risk factors for congenital GI tract atresia. We used data from a Japanese nationwide birth cohort study launched in 2011, and examined whether fish consumption in early pregnancy was associated with congenital GI tract atresia. We analysed data of 89 495 women (mean age at delivery=31·2 years) who delivered singleton live births without chromosomal anomalies. Based on the results of the FFQ, we estimated the daily intake of fish and n-3 PUFA consumption in early pregnancy. We defined a composite outcome (oesophageal atresia, duodenal atresia, jejunoileal atresia and/or anorectal malformation) as congenital GI tract atresia. In this population, median fish intake was 31·9 g/d, and seventy-four cases of congenital GI tract atresia were identified. Fish consumption in early pregnancy was inversely associated with the composite outcome (multivariable-adjusted OR for the high v. low consumption category=0·5, 95 % CI 0·3, 1·0). For all the specific types of atresia, decreased OR were observed in the high consumption category, although not statistically significant. Reduced atresia occurrence was observed even beyond the US Food and Drug Administration's recommended consumption of no more than 340 g/week. Also, n-3 PUFA-rich fish and n-3 PUFA consumptions tended to be inversely associated with atresia. Fish consumption in early pregnancy may be a preventive factor for congenital GI tract atresia.

Jejuno-ileal atresia: a 2-year preliminary study on presentation and outcome.

BACKGROUND/AIM: Intestinal atresia is a common cause of neonatal intestinal obstruction. Jejuno-ileum is the commonest site of intestinal atresia. Reports on Jejunoileal atresia in developing countries are still few. The purpose of this study is to determine the presentation and management outcomes of neonates with Jejunoileal atresia treated in our hospital. MATERIALS AND METHODS: Detailed data on all babies that presented and were treated within the study period (November2008-November, 2010) were kept and analyzed. A management protocol was put up and maintained. RESULT: A total of 9 babies (7males and 2 females) were treated. They were aged 2 hours to 13 days. Their weight ranged from 1.7kg to 3.3kg. Apart from one baby which presented within 2hrs with prenatal ultrasound diagnosis, others had bilious vomiting from the first day of birth, abdominal distension and delayed or absent passage of meconium. Even though symptoms developed on the first day of birth, presentation to the surgical unit was delayed 72hours and beyond in most patients.Type I atresia is commonest (no=4).There is associated gut malrotation in 2 babies. Five babies had complications which included surgical site infection, sepsis, prolonged vomiting post operatively, aspiration, rupture of dilated proximal segment after membrane excision, entero-cutaneous fistula and malnutrition. Three babies died giving a mortality of 33.3%. Mortality is commoner in types IIIb and IV. CONCLUSION: Mortality is higher in complex atresia which most times will require neonatal intensive care and parenteral nutrition facilities. These are still lacking in our institution. Providing these facilities will further improve outcome.
