RESUMO
The aim of our study was to determine the frequency and type of associated congenital anomalies in patients with isolated gastroschisis born at the Dr. Juan I. Menchaca Civil Hospital of Guadalajara (Guadalajara, México), and to explore its possible association with the included outcome variables. One hundred-eight cases with isolated gastroschisis were reviewed from 2009 to 2014. The occurrence of intestinal and extraintestinal associated anomalies (either secondary or primary) was prospectively assessed. The type of gastroschisis, length of hospital stay (LOS), and in-hospital mortality were outcome variables for statistical analysis. Of infants with gastroschisis, 52 (48.1%) had one or more associated anomalies (AA), with increased odds in males (OR = 2.3, 95%CI: 1.1-5.0). AA classified, as secondary and primary were present in 34.3 and 5.6% of patients, respectively. Of secondary AA, 25.9% were intestinal anomalies, and 17.6% were extraintestinal. Primary AA were congenital heart disease (n = 3), meningomyelocele, and hydrocephaly and amniotic band sequence in one instance, respectively. Multivariate logistic regression showed that secondary AA (both intestinal and extraintestinal) were associated with complex gastroschisis, prolonged LOS, and in-hospital death, whereas primary AA were not related to a worse outcome. Our results highlight the pathogenic importance of properly investigating and categorizing the presence of others secondary or primary AA when diagnosis of gastroschisis is made.

Mexico is recognized as a country with a high prevalence of gastroschisis, although the cause of this remains unclear. We define the prevalence and potential risk factors for gastroschisis in a public hospital from west México. A case-control study was conducted among 270 newborns, including 90 patients with nonsyndromic gastroschisis (cases) and 180 infants without birth defects (controls), born all during the period 2009 to 2013 at the Hospital Civil de Guadalajara "Dr. Juan I. Menchaca" (Guadalajara, Mexico), from a total of 51,145 live births. Potential maternal risk factors for gastroschisis were compared using multivariate logistic regression analysis to evaluate the deviance explained by different variables of interest. The overall prevalence of gastroschisis in live births was 17.6 per 10,000 births (95% confidence interval [CI] 14.0-21.2), whereas in offspring of women ≤ 19 years old was 29.9 per 10,000 births (95% CI 21.9-38.0). Mothers ≤ 19 years (adjusted odds ratio [aOR] 2.8: 95% CI 1.5-5.1), anemia during pregnancy (aOR 10.7; 95% CI 2.0-56.9), first-trimester exposure to hormonal contraceptives (aOR 3.7; 95% CI 1.0-13.0), and first-trimester alcohol consumption (aOR 3.4; 95% CI 1.6-7.3), were associated with gastroschisis. Contrarily, adjusted OR for pre-pregnancy body mass index ≥ 25 kg/m(2) has protective odds (aOR 0.2; 95% CI 0.1-0.5). Our results suggest an increased risk for gastroschisis among mothers under the age of 20, with anemia during pregnancy, and those who used hormonal contraceptives or consumed alcohol during early pregnancy, whereas, pre-pregnancy overweight has a protective OR, and they are discussed as clues in its pathogenesis.
