Paediatrics: Gastroschisis and Exomphalos: Free MSRA Podcast

⚕️ FREE MSRA PODCAST – Gastroschisis🎧 A high-yield breakdown of this neonatal surgical emergency – perfect for MSRA exam prep and real-life paediatrics.🧠 Key Learning Points📌 Definition• Gastroschisis is a congenital abdominal wall defect• Abdominal contents (typically bowel) herniate without a covering sac• The defect is usually located to the right of the umbilicus📌 Causes & Risk Factors• Exact cause unknown – failure of abdominal wall closure in fetal development• Risk factors:• Young maternal age• Maternal smoking or drug use• Environmental exposure (non-specific)• May occur without identifiable risk factors📌 Pathophysiology• Incomplete fusion of abdominal wall layers• Leads to bowel herniation directly into amniotic fluid• Lack of membrane → direct exposure to amniotic fluid → inflammation and damage📌 Symptoms• Visible externalised bowel loops at birth• Usually no covering membrane• Opening <5 cm and just right of umbilicus• May be associated with intestinal atresia, polyhydramnios prenatally📌 Differential Diagnosis• Exomphalos (omphalocele) – midline, covered by membrane, often with chromosomal abnormalities• Umbilical hernia• Bladder exstrophy• Amniotic band syndrome• Limb–body wall complex📌 Diagnosis• Prenatal ultrasound – detects bowel loops outside abdomen• Maternal serum alpha-fetoprotein (MSAFP) – raised, often higher in gastroschisis than exomphalos• Amniocentesis if genetic conditions suspected• Postnatal: physical exam + further imaging (renal USS, echocardiogram if needed)📌 Management• Multidisciplinary neonatal team essential• Initial stabilisation:• Protect exposed bowel with sterile dressing or silo• Manage fluids, temperature, and start IV antibiotics• Surgical repair:• Primary closure (if feasible)• Or use of a silo to gradually reduce bowel before delayed closure• Postoperative care:• Parenteral nutrition, careful monitoring, and feeding support• Urine output & central line care📌 Complications• Intestinal atresia (10–20%)• Malabsorption and bowel dysmotility• Short bowel syndrome• Infection or sepsis• Tight abdominal closure → compromised ventilation or cardiac output📌 Prognosis• Generally favourable if well managed• Worse prognosis if:• Major bowel complications• Prematurity• Associated anomalies• Compared to exomphalos, less likely linked to chromosomal syndromes📎 More MSRA Resources for Gastroschisis📝 Revision Notes: https://www.passthemsra.com/topic/gastroschisis-revision-notes/🧠 Flashcards: https://www.passthemsra.com/topic/gastroschisis-flashcards/💬 Accordion Q&A Notes: https://www.passthemsra.com/topic/gastroschisis-accordion-qa-notes/🚀 Rapid Quiz: https://www.passthemsra.com/topic/gastroschisis-rapid-quiz/🎯 Topic Quiz Page: https://www.passthemsra.com/quizzes/gastroschisis/🎓 Full Paediatrics Course: https://www.passthemsra.com/courses/paediatrics-for-the-msra/#MSRA #MSRARevision #MSRATextbook #MSRAQuiz #MSRAQuestionBank #MSRAFlashcards #MSRAQandANotes #MSRAAccordions #MultiSpecialtyRecruitmentAssessment #MSRAOnlineRevision #MSRARevisionWebsite #Paediatrics #Gastroschisis
