Definition
A congenital defect with major fissure in the abdominal wall lateral to, but not at, the umbilicus. This results in the extrusion of viscera. Unlike omphalocele, herniated structures in gastroschisis are not covered by a sac or peritoneum.

Reading the evidence in rare and inherited diseases
Rare conditions are difficult to study: few patients means small studies, case reports and registries are common, and randomized trials are the exception. Small samples limit precision and can exaggerate effects, and cases reported in the literature may be the most severe or unusual. Evidence from many small studies is best read together. Check how patients were identified, how many were included and how long they were followed.
Evidence from open-access studies

ObjectiveOutcome reporting heterogeneity impedes identification of gold standard treatments for children born with gastroschisis. Use of core outcome sets (COSs) in research reduces outcome reporting heterogeneity and ensures that studies are relevant to patients. The aim of this study was to develop a gastroschisis COS.Design and settingSystematic reviews and stakeholder nomination were used to identify candidate outcomes that were subsequently prioritised by key stakeholders in a three-phase online Delphi process and face-to-face consensus meeting using a 9-point Likert scale. In phases two and three of the Delphi process, participants were shown graphical and numerical representations of their own, and all panels scores for each outcome respectively and asked to review their previous score in light of this information. Outcomes were carried forward to the consensus meeting if prioritised by two or three stakeholder panels in the third phase of the Delphi process. The COS was formed from outcomes where ≥70% of consensus meeting participants scored the outcome 7-9 and Results71 participants (84%) completed all phases of the Delphi process, during which 87 outcomes were assessed. Eight outcomes, mortality, sepsis, growth, number of operations, severe gastrointestinal complication, time on parenteral nutrition, liver disease and quality of life for the child, met criteria for inclusion in the COS.ConclusionsEight outcomes have been included in the gastroschisis COS as a result of their importance to key stakeholders. Implementing use of the COS will increase the potential for identification of gold standard treatments for the management of children born with gastroschisis.

Prevalence of gastroschisis, a serious birth defect of the abdominal wall resulting in some of the abdominal contents extending outside the body at birth, has been increasing worldwide (1,2). Gastroschisis requires surgical repair after birth and is associated with digestive and feeding complications during infancy, which can affect development. Recent data from 14 U.S. states indicated an increasing prevalence of gastroschisis from 1995 to 2012 (1). Young maternal age has been strongly associated with gastroschisis, but research suggests that risk factors such as smoking, genitourinary infections, and prescription opioid use also might be associated (3-5). Data from 20 population-based state surveillance programs were pooled and analyzed to assess age-specific gastroschisis prevalence during two 5-year periods, 2006-2010 and 2011-2015, and an ecologic approach was used to compare annual gastroschisis prevalence by annual opioid prescription rate categories. Gastroschisis prevalence increased only slightly (10%) from 2006-2010 to 2011-2015 (prevalence ratio = 1.1, 95% confidence interval [CI] = 1.0-1.1), with the highest prevalence among mothers aged <20 years. During 2006-2015, the prevalence of gastroschisis was 1.6 times higher in counties with high opioid prescription rates (5.1 per 10,000 live births; CI = 4.9-5.3) and 1.4 times higher where opioid prescription rates were medium (4.6 per 10,000 live births; CI = 4.4-4.8) compared with areas with low prescription rates (3.2 per 10,000 live births; CI = 3.1-3.4). Public health research is needed to understand factors contributing to the association between young maternal age and gastroschisis and assess the effect of prescription opioid use during pregnancy on this pregnancy outcome.

IntroductionZonulin (ZO), a new diagnostic biomarker of intestinal permeability, was tested in newborns presenting symptoms of infection and/or inflammation of the gut or being at risk of intestinal pathology.Material and methodsSerum ZO was assessed in 81 newborns diagnosed with sepsis, necrotizing enterocolitis (NEC), rotavirus infection, and gastroschisis, also in extremely low gestational age babies, and in controls (healthy newborns). ZO concentration was compared to C-reactive protein (CRP) and procalcitonin (PCT) values, leucocyte and platelet count, basic demographic data, and the value of the Neonatal Therapeutic Intervention Scoring System (NTISS).ResultsMedian values of ZO were markedly higher in groups with rotavirus infection and gastroschisis (36.0 (1-3Q: 26.0-43.2) and 20.3 (1-3Q: 17.7-28.2) ng/ml, resp.) versus controls (3.5 (1-3Q: 2.7-4.8) ng/ml). Its concentration in the NEC group was twice as high as in controls but did not reach statistical significance. ZO levels were not related to NTISS, CRP, and PCT.ConclusionsZonulin is a promising biomarker of intestinal condition, markedly elevated in rotavirus infections. Its role in defining the severity of necrotizing enterocolitis and the risk for perforation is not well described and needs further evaluation. An increase in zonulin may not be parallel to the release of inflammatory markers, and low CRP should not exclude an injury to neonatal intestine.

BackgroundInfants with gastroschisis often experience prolonged stays in hospital as they transition from parenteral nutrition to enteral feeds. The purpose of this study was to assess the evidence for the use of exclusive human milk compared to formula in these patients.MethodsA structured search was performed using Medline, Embase, and Cochrane Central from inception until March 2025. We included comparative studies of infants with gastroschisis who received exclusive human milk versus supplemental or exclusive formula. Screening and data extraction were completed by two independent reviewers. Results from included studies were meta-analyzed using a random-effects model and reported as risk ratios (RR) with 95% confidence intervals (CI). Risk of bias assessments were performed using the Newcastle-Ottawa Scale. Outcomes included time to enteral autonomy, necrotizing enterocolitis, sepsis, cholestasis, and mortality. Certainty of evidence was summarized using Grading of Recommendations, Assessment, Development and Evaluations criteria.ResultsWe identified 3661 infants with gastroschisis from six retrospective cohort studies and one case-control study. Exclusive human milk was associated with a reduced risk of mortality (RR = 0.38, 95% CI: 0.15-0.99, I2 = 0%). There were no statistically significant differences between groups for necrotizing enterocolitis, cholestasis, or sepsis. These findings were supported by low quality evidence based on retrospective data.ConclusionsThe best available evidence suggests that exclusive breast milk is associated with reduced mortality compared to formula among infants with gastroschisis. This estimate is based on data from retrospective studies. Further research is needed to clarify the role of donor human milk.
