NCT07030309

Brief Summary

The purpose of this observational study is to evaluate selected epidemiological aspects of gastroschisis (GS) and factors affecting health outcomes of newborns with this diagnosis in a population of fetuses with gastroschisis. The main questions the study aims to answer are:

  • Are there correlations between the parameters of ultrasound evaluation of the bowel with the condition of the newborn's bowel as assessed by the surgeon?
  • What is the prevalence of the different forms of GS (classification according to the methodology of Molik et al. 2002, Perrone et al. 2018)?
  • What is the incidence of perioperative and postoperative complications and other complications of the neonatal period?
  • What is the relationship between the form of the defect (simple GS vs complex GS) and feeding milestones - TFEF, TPN, TSEF, TSOF, TFOF?
  • What is the relationship between clinical parameters, diagnostic and therapeutic management, including method and timing of delivery, and final outcomes? Participants will not perform any active tasks or receive interventions as part of this study. Data will be collected passively from historical medical records including prenatal test results, details of pregnancy, delivery, and postnatal information on the newborn's treatment. The information collected will be anonymized. The study aims to collect information on prenatal diagnosis and neonatal outcomes, analyze factors affecting final results, and develop the most optimal management regimen for GS in Poland.

Outcome Measures

Primary Outcomes (1)

  • The prevalence of different forms of GS

    The prevalence of different forms of GS: simple, complex

    During primary surgery

Secondary Outcomes (22)

  • Agreement rate between prenatal and neonatal assessment of the bowel condition

    Prenatal assessment - during every US examination up to the time of delivery; newborn's evaluation - during primary surgery

  • Prevalence of necrotizing enterocolitis (NEC)

    Up to 28 days after birth

  • Prevalence of short bowel syndrome (SBS)

    During primary surgery or reoperation

  • Prevalence of newborn sepsis

    Up to 28 days after birth

  • Time to full enteral feeding (TFEF)

    From date of birth until the first day when full enteral feeding is achieved, assessed up to 28 days after birth.

  • +17 more secondary outcomes

Study Arms (2)

simple gastroschisis

isolated gastroschisis, without intestinal anomalies

Other: Gastroschisis

complex gastroschisis

gastroschisis with intestinal atresias, perforations, necrosis or volvulus

Other: Gastroschisis

Interventions

Gastroschisis (GS) is a congenital abdominal wall defect in which the intestine is located outside the abdominal cavity. The prevalence of the GS classifies it as a rare disease (ORPHA:2368) Pregnancy complicated by gastroschisis is associated with an increased risk of serious perinatal complications. The presence of accompanying intestinal anomalies (atresia, necrosis, perforation, and volvulus), which qualifies the defect in the cGS (complex gastroschisis) group, as opposed to sGS (simple gastroschisis), where these anomalies are absent. cGS is associated with significantly increased neonatal morbidity and mortality when compared to sGS.

Study Population

The study population for the MEGA Study consists of fetuses diagnosed with gastroschisis. The specific criteria for inclusion in the study are: * Fetuses with a diagnosis of gastroschisis. * Availability of prenatal, delivery, and postnatal documentation (up to hospital discharge, transfer to another center, or death). The exclusion criterion for the study is: • Pregnancies terminated before 22 weeks of gestation. The time frame for data included in the study is 2011 - 2024, although a shorter observation period may be applied depending on the availability of data at a participating center.

You may qualify if:

  • A fetus with a diagnosis of gastroschisis;
  • Availability of prenatal, delivery and postnatal records (for hospital discharge, transfer to another facility or death).

You may not qualify if:

  • pregnancies terminated before the 22nd week of pregnancy

Data Sharing

IPD Sharing
Will share

Individual participant data (IPD) will be analyzed for the purposes of the study but will not be shared. Only aggregate results will be published. Reason for not sharing IPD: The study protocol does not include plans for IPD sharing. Due to ethical considerations and data protection policies, only anonymized, group-level data will be included in publications and reports.
