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.

Interventions

OTHERGastroschisis

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.

Design outcomes

Primary

MeasureTime frameDescription
The prevalence of different forms of GSDuring primary surgeryThe prevalence of different forms of GS: simple, complex

Secondary

MeasureTime frameDescription
Prevalence of necrotizing enterocolitis (NEC)Up to 28 days after birthDiagnosis of necrotizing enterocolitis (NEC) is based on sudden onset of feeding intolerance, abdominal distention, bloody stools, and signs of sepsis (i.e., changes in the heart rate, respiratory rate, temperature, and blood pressure) in preterm infants, according to the Bell scale, which integrates the clinical and radiological manifestations.
Prevalence of short bowel syndrome (SBS)During primary surgery or reoperationDiagnosis of short bowel syndrome (SBS) is in case of loss of bowel length or function significantly enough to cause malabsorption, requiring lifelong parenteral support
Prevalence of newborn sepsisUp to 28 days after birthNewborn sepsis - an infection involving the bloodstream in infants under 28 days old. The clinical syndrome with symptomatology and laboratory findings consistent with a systemic inflammatory response to a multimodal infection caused by bacteria viruses, fungi potentially leading to multiple organ dysfunction, failure and even death within the first 28 days of life.
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.Time to full enteral feeding (TFEF) - the time when neonates start to receive all of their prescribed nutrition as milk feeds
Duration of the total parenteral nutrition (TPN)From the first day of TPN initiation until the last day of TPN administration, assessed up to 28 days after birth.Total Parenteral Nutrition (TPN) - duration of parenteral nutrition, the time of intravenous feeding of nutritional products
Time to start enteral feeding (TSEF)From date of birth until the first day enteral feeding is initiated, assessed up to 14 days after birth.Time to start enteral feeding (TSEF) - the time when neonates start enteral nutrition
Time to start oral feeding (TSOF)From date of birth until the first day of oral feeding initiation, assessed up to 28 days after birth.Time to start oral feeding (TSOF)- the time when neonates start oral feeding
Time to full oral feeding (TFOF)From date of birth until the first day full oral feeding is achieved, assessed up to 28 days after birth.Time to full oral feeding (TFOF) - the time to achieve oral exclusive feeding, without using additional or alternative feeding methods (such as gavage or nasogastric tube)
Lenght of hospital stay (LOS)Time from the newborn's birth to discharge from the hospital, up to 28 days after birthLenght of hospital stay (LOS) - duration of hospitalization - a clinical metric that measures the time elapsed between a patient's hospital admittance and discharge. For newborns - the time between the day of birth and its discharge
Prevalence of modes of deliveryAt deliveryMode of delivery - method of pregnancy termination: vaginal delivery or cesarean delivery
Agreement rate between prenatal and neonatal assessment of the bowel conditionPrenatal assessment - during every US examination up to the time of delivery; newborn's evaluation - during primary surgeryComparison of the prenatal ultrasound bowel condition and the newborn's bowel assessment by the surgeon
Time to repair (primary surgery)From date and time of birth until the start of the primary surgical repair, up to 28 days after birthTime to repair (primary surgery); even primary closure or SILO \[hours\]
Time to closure abdominal wall defectFrom date and time of birth until the completion of definitive abdominal wall defect closure, up to 28 days after birthTime to abdominal wall defect closure, even primary or secondary \[hour\]
Prevalence of neonatal deathUp to 28 days after birthNeonatal death within the first 28 days of life

Prevalence of gastroschis types by Perrone et al. 2018During primary surgery, up to 28 days after birthType A: ischemic bowel, significantly constricted at the ring without atresia Type B: ischemic bowel, significantly constricted at the ring (but viable) with an associated atresia Type C: ischemic bowel with a closing ring with nonviable external bowel (necrosis) with or without an associated atresia Type D: a completely closed defect with either a nubbin of exposed tissue or no external bowel
