1. Disease Information

1.1 What is omphalocele? (current definition)

Omphalocele is a congenital midline abdominal wall defect at the umbilicus/base of the umbilical cord in which abdominal viscera herniate outside the abdomen, typically covered by a membranous sac (often described as peritoneum/Wharton’s jelly/amnion layers). (malhotra2023enhancingomphalocelecare pages 1-3)

A population-based Danish register study similarly describes omphalocele (exomphalos) as herniation of abdominal contents through the umbilical insertion, often categorized clinically as small (no liver herniation) vs large (liver herniation). (laustenthomsen2024omphaloceleprevalenceand pages 1-2)

1.2 Synonyms and alternative names

1.3 Evidence sources (aggregated vs individual)

The information summarized here is derived from: - Aggregated, disease-level resources: nationwide population-based registry cohorts (Denmark, Sweden, Finland) (laustenthomsen2024omphaloceleprevalenceand pages 1-2, fogelstrom2021omphalocelenationalcurrent pages 1-2, raitio2021omphaloceleinfinland pages 5-9) - Aggregated cohort studies: tertiary-center prenatal cohort (China) (que2023ultrasonographiccharacteristicsgenetic pages 1-2, que2023ultrasonographiccharacteristicsgenetic pages 4-6) - Clinical case series/implementation studies: staged closure traction device; compression-dressing management (ziegler2024useofa pages 5-7, widatella2024acaseseries pages 1-3)

2. Etiology

2.1 Primary causes (current understanding)

Omphalocele is generally regarded as a developmental/embryologic defect of ventral body wall formation; its etiology is often multifactorial, with a prominent contribution from genetic and chromosomal abnormalities and syndromic conditions. (malhotra2023enhancingomphalocelecare pages 1-3, laustenthomsen2024omphaloceleprevalenceand pages 1-2)

Direct abstract-supported definition-related embryology in the 2023 review notes that physiologic midgut herniation occurs at ~6–10 weeks’ gestation, and persistence/failure of normal return is part of the conceptual embryologic framework used clinically when distinguishing normal from pathologic herniation. (malhotra2023enhancingomphalocelecare pages 3-5)

2.2 Risk factors

Maternal and demographic associations are reported in review-level sources (with heterogeneous evidence quality). A 2023 narrative review lists potential risk factors including advanced maternal age, and exposures such as smoking, alcohol, aspirin, SSRIs, and certain nutritional factors (e.g., high-dose vitamin E; abnormal vitamin B12 production). These should be interpreted cautiously as they are not uniformly supported across high-quality population-based causal studies. (malhotra2023enhancingomphalocelecare pages 3-5)

For giant omphalocele, prognostic/risk correlates for adverse outcomes include chromosomal anomalies, congenital heart defects, CNS defects, lung hypoplasia, defect size, and birth weight, as summarized in the European Paediatric Surgeons’ Association (EUPSA) consensus statement synthesis. (saxena2025europeanpaediatricsurgeons pages 7-8)

2.3 Protective factors

No protective factors with strong direct evidence were identified in the retrieved corpus.

2.4 Gene–environment interactions

No specific, well-validated gene–environment interaction mechanisms were identified in the retrieved corpus.

3. Phenotypes (clinical manifestations)

3.1 Core phenotype

3.2 Common associated phenotypes/conditions (with data)

Omphalocele is frequently non-isolated and associated with other malformations/syndromes: - In Denmark (live births 1997–2021), 53.7% had ≥1 major malformation and 17.0% had a syndrome diagnosis. (laustenthomsen2024omphaloceleprevalenceand pages 1-2) - In Sweden (1997–2016), 62% of live-born cases had associated malformations and/or genetic disorders; ventricular septal defect was the most common associated malformation. (fogelstrom2021omphalocelenationalcurrent pages 1-2, fogelstrom2021omphalocelenationalcurrent pages 2-4)

A detailed prenatal cohort from China (120 fetuses) reported high rates of associated abnormalities in non-isolated cases, with ultrasound categories including cardiovascular, skeletal, CNS, and facial anomalies; the most common ultrasound category in the cohort table was cardiovascular findings. (que2023ultrasonographiccharacteristicsgenetic pages 4-6)

3.3 Pulmonary complications (important for giant omphalocele)

A literature review emphasizes pulmonary hypoplasia and pulmonary hypertension as key complications that worsen neonatal prognosis, particularly in giant omphalocele where reduced intra-abdominal capacity may restrict fetal lung expansion. (namat2025omphaloceleandassociated pages 11-13)

It is useful for populating phenotype annotations in a disease knowledge base, especially for distinguishing core defects from common associated cardiopulmonary and neurodevelopmental complications.

4. Genetic/Molecular Information

4.1 Chromosomal abnormalities and syndromic associations

Population cohorts show frequent co-occurrence with chromosomal diagnoses: - Sweden: trisomy 13 (n=8), trisomy 18 (n=4), trisomy 21 (n=4) among 207 liveborn cases (with markedly elevated mortality in the chromosomal-abnormality subgroup). (fogelstrom2021omphalocelenationalcurrent pages 2-4, fogelstrom2021omphalocelenationalcurrent pages 4-5) - China prenatal cohort (tested subset): trisomy 18 (3), trisomy 13 (1), and a chromosome 8–11 translocation (1) among those undergoing karyotype+CMA. (que2023ultrasonographiccharacteristicsgenetic pages 1-2)

4.2 Recommended prenatal genetic testing workflow

A stepwise strategy supported by cohort data and review synthesis is: 1) Karyotype + chromosomal microarray (CMA) as first-line testing in prenatal omphalocele. (que2023ultrasonographiccharacteristicsgenetic pages 1-2, namat2025omphaloceleandassociated pages 11-13) 2) WES if karyotype and CMA are normal, especially in non-isolated cases; the Chinese cohort found abnormal WES results in 3/6 selected cases with normal karyotype/CMA, including variants in COL2A1 and SCP2, and an SDHB finding (details in source). (que2023ultrasonographiccharacteristicsgenetic pages 4-6)

The prenatal genetic testing summary table is provided below.

Table (click to expand)
Test modality When to use in prenatal omphalocele Diagnostic yield / typical findings Example abnormalities detected or targeted Supporting sources
Conventional karyotype Recommended routinely once fetal omphalocele is diagnosed prenatally, especially for non-isolated cases or when additional ultrasound abnormalities are present Detects aneuploidy and large structural chromosome abnormalities; in one 2023 cohort, 35 patients underwent karyotype+CMA and 5/35 (14.3%) had chromosomal abnormalities; all abnormal karyotypes were in non-isolated cases Trisomy 18 (3 cases), trisomy 13 (1 case), trisomy 21 is a recognized recurrent association, chromosome 8;11 translocation (1 case) (que2023ultrasonographiccharacteristicsgenetic pages 1-2, que2023ultrasonographiccharacteristicsgenetic pages 4-6, fogelstrom2021omphalocelenationalcurrent pages 2-4) (que2023ultrasonographiccharacteristicsgenetic pages 1-2, que2023ultrasonographiccharacteristicsgenetic pages 4-6, fogelstrom2021omphalocelenationalcurrent pages 2-4)
Chromosomal microarray (CMA) Recommended together with karyotype as first-line prenatal genetic testing for omphalocele; useful when ultrasound suggests associated anomalies and for clarifying submicroscopic CNVs Adds genome-wide CNV detection beyond karyotype; in the Que et al. cohort, CMA was performed with karyotype in 35 cases and was normal in 6 selected non-isolated cases later escalated to WES; parental blood/pedigree analysis is recommended when CMA yields VUS Can detect pathogenic/likely pathogenic CNVs not visible on karyotype; examples in the cohort were mainly normal CMA followed by WES escalation rather than specific recurrent CNVs reported in the excerpt (que2023ultrasonographiccharacteristicsgenetic pages 1-2, que2023ultrasonographiccharacteristicsgenetic pages 2-4, que2023ultrasonographiccharacteristicsgenetic pages 8-9) (que2023ultrasonographiccharacteristicsgenetic pages 1-2, que2023ultrasonographiccharacteristicsgenetic pages 2-4, que2023ultrasonographiccharacteristicsgenetic pages 8-9)
QF-PCR Rapid adjunct test when rapid confirmation of common aneuploidies is needed, particularly if trisomy is strongly suspected on ultrasound Fast targeted confirmation rather than genome-wide discovery; highlighted as useful for rapid confirmation of trisomy 13 in review evidence Trisomy 13, and by standard panel use also common autosomal trisomies such as T18/T21 when suspected (namat2025omphaloceleandassociated pages 11-13) (namat2025omphaloceleandassociated pages 11-13)
Whole exome sequencing (WES) Consider when karyotype and CMA are normal, especially in non-isolated omphalocele or persistent suspicion of syndromic/genetic disease In Que et al., 6 non-isolated cases with normal karyotype/CMA underwent WES and 3/6 had abnormal findings (1 pathogenic, 2 suspected pathogenic); review evidence notes WES may increase diagnostic yield by ~8–10% after normal karyotype/CMA COL2A1 c.2759C>A (p.Pro920His), SCP2 c.674+1G>C, SDHB c.725G>A (p.R242H); review also notes WES is an option after normal karyotype/CMA and may improve yield (que2023ultrasonographiccharacteristicsgenetic pages 1-2, que2023ultrasonographiccharacteristicsgenetic pages 4-6, que2023ultrasonographiccharacteristicsgenetic pages 2-4, que2023ultrasonographiccharacteristicsgenetic pages 8-9, namat2025omphaloceleandassociated pages 11-13) (que2023ultrasonographiccharacteristicsgenetic pages 1-2, que2023ultrasonographiccharacteristicsgenetic pages 4-6, que2023ultrasonographiccharacteristicsgenetic pages 2-4, que2023ultrasonographiccharacteristicsgenetic pages 8-9, namat2025omphaloceleandassociated pages 11-13)
Stepwise prenatal testing strategy Practical recommendation for current care pathways in prenatally diagnosed omphalocele Start with karyotype + CMA because aneuploidy risk is elevated; escalate to WES if first-line testing is normal; if all are normal but phenotype remains suggestive, additional syndrome-specific testing may be needed Common prenatal genetic associations include T13, T18, T21; structural rearrangements such as t(8;11); monogenic findings by WES may include COL2A1, SCP2, SDHB; if karyotype/CMA/WES are normal, additional testing may be required to evaluate disorders such as Beckwith-Wiedemann syndrome (que2023ultrasonographiccharacteristicsgenetic pages 1-2, que2023ultrasonographiccharacteristicsgenetic pages 8-9, namat2025omphaloceleandassociated pages 11-13) (que2023ultrasonographiccharacteristicsgenetic pages 1-2, que2023ultrasonographiccharacteristicsgenetic pages 8-9, namat2025omphaloceleandassociated pages 11-13)

Table: This table summarizes the main prenatal genetic testing modalities used for omphalocele, when each is recommended, and the kinds of abnormalities they can detect. It is useful for structuring a diagnostic workflow from aneuploidy testing through exome sequencing in isolated and non-isolated cases.

4.3 Mechanistic / pathway detail

The retrieved evidence primarily supports a developmental malformation framework with strong genetic/chromosomal contributions rather than a single molecular pathway model. Molecular pathway enrichment, epigenetic signatures, or omics profiling specific to omphalocele were not identified in the retrieved corpus.

5. Environmental Information

No specific infectious etiologies were identified. Environmental/lifestyle associations are discussed in review-level sources but without strong causal confirmation from the evidence retrieved here. (malhotra2023enhancingomphalocelecare pages 3-5)

6. Mechanism / Pathophysiology

6.1 Causal chain (high-level)

Primary developmental defect → failure to achieve normal abdominal domain/closure at umbilicus → herniation of viscera (often including liver in large/giant cases) → viscero-abdominal disproportion → perinatal cardiopulmonary vulnerability; repair decisions must avoid dangerous rises in intra-abdominal pressure that can precipitate abdominal compartment syndrome and multi-organ physiologic compromise. (namat2025omphaloceleandassociated pages 11-13)

6.2 Pulmonary hypoplasia and pulmonary hypertension

Pulmonary hypoplasia and pulmonary hypertension are emphasized as major contributors to neonatal morbidity/mortality in large/giant omphalocele, likely related to constrained fetal thoracoabdominal dynamics and pulmonary vascular development. (namat2025omphaloceleandassociated pages 11-13)

Suggested GO biological process terms (GO): - GO:0001944 vasculature development (re pulmonary vascular development) - GO:0030324 lung development - GO:0003015 heart process (hemodynamic consequences)

Suggested cell types (CL): - CL:0002062 pulmonary artery endothelial cell - CL:0002543 lung microvascular endothelial cell

(These ontology suggestions are based on mechanistic interpretation of the cited review’s pulmonary-development framing; direct single-cell evidence was not retrieved.) (namat2025omphaloceleandassociated pages 11-13)

8. Temporal Development

8.1 Onset

8.2 Course/progression

Immediate neonatal course depends strongly on: - Isolated vs non-isolated status (que2023ultrasonographiccharacteristicsgenetic pages 1-2) - Cardiopulmonary status (pulmonary hypoplasia/hypertension; CHD) (namat2025omphaloceleandassociated pages 11-13, saxena2025europeanpaediatricsurgeons pages 7-8)

9. Inheritance and Population

9.1 Epidemiology (recent population-based statistics)

Population-based estimates vary by ascertainment (live births only vs total including terminations). Key recent benchmarks include: - Denmark live births (1997–2021): 0.98 per 10,000 live births. (laustenthomsen2024omphaloceleprevalenceand pages 1-2) - Sweden live births (1997–2016): 1 per 10,000 live births; prenatal diagnosis frequently leads to termination. (fogelstrom2021omphalocelenationalcurrent pages 1-2, fogelstrom2021omphalocelenationalcurrent pages 2-4) - Finland total prevalence including terminations (1993–2014): 4.71 per 10,000 births, with birth prevalence 1.96/10,000 and live-birth prevalence 1.69/10,000; 55% terminations. (raitio2021omphaloceleinfinland pages 5-9)

Study (country) Years Design n (cases) Prevalence (per 10,000 live births or total) Termination rate Associated anomalies % Key anomalies 1-year mortality/survival
Lausten-Thomsen 2024 (Denmark) 1997–2021 Nationwide register-based live-birth cohort 147 liveborn infants with omphalocele among 1,498,685 live births 0.98 per 10,000 live births (95% CI 0.83–1.15) Not directly estimated in cohort; authors note European prenatal termination rates often exceed 50% 53.7% had ≥1 major malformation; additional 17.0% had a diagnosed syndrome Broad co-occurring defects affecting cardiac, renal, limb, and CNS systems; syndromic/chromosomal conditions noted Not reported in extracted context (laustenthomsen2024omphaloceleprevalenceand pages 1-2)
Fogelström 2021 (Sweden) 1997–2016 Nationwide population-based cohort 207 live-born cases; 449 prenatally diagnosed pregnancies 1.0 per 10,000 live births 59% of prenatally diagnosed pregnancies (263/449) 62% had associated malformations and/or genetic disorders Ventricular septal defect most common; ASD also frequent; trisomy 13 (n=8), trisomy 18 (n=4), trisomy 21 (n=4) reported 13% mortality within 1 year; ~87% 1-year survival (fogelstrom2021omphalocelenationalcurrent pages 1-2, fogelstrom2021omphalocelenationalcurrent pages 2-4, fogelstrom2021omphalocelenationalcurrent pages 4-5)
Raitio 2021 (Finland) 1993–2014 Nationwide population-based register study 600 total cases: 229 live births, 39 stillbirths, 332 terminations Total prevalence 4.71 per 10,000 births; birth prevalence 1.96 per 10,000; live-birth prevalence 1.69 per 10,000 55% (332/600) Among liveborns, 18% had multiple anomalies; chromosomal abnormalities 9.3% overall; isolated cases 77% of liveborns Chromosomal abnormalities 9.3%; heart defects 6.3%; CNS anomalies 3.0%; GI and urogenital malformations 2.0% each; Beckwith-Wiedemann noted among syndromes Overall infant mortality 22%; 1-year survival 80% isolated, 88% multiple anomalies, 17% chromosomal defects (raitio2021omphaloceleinfinland pages 5-9, raitioUnknownyearomphaloceleinfinland pages 1-5)
Que 2023 (China) 2015–2022 Single tertiary-center prenatal cohort 120 fetuses with prenatal omphalocele; 112 followed Not a population prevalence study 71.4% of followed pregnancies (80/112) requested termination 77.5% non-isolated (93/120); 22.5% isolated (27/120) Cardiac anomalies common (17 fetuses); broader ultrasound findings included cardiovascular, skeletal, CNS, facial anomalies; chromosomal findings: trisomy 18 (n=3), trisomy 13 (n=1), translocation 8–11 (n=1); WES identified pathogenic/suspected pathogenic variants including COL2A1, SCP2, SDHB Among 25 live births, 72% survived to 1 year (7/25 died in first year) (que2023ultrasonographiccharacteristicsgenetic pages 1-2, que2023ultrasonographiccharacteristicsgenetic pages 4-6, que2023ultrasonographiccharacteristicsgenetic pages 2-4)

Table: This table summarizes recent and foundational cohort data on omphalocele prevalence, associated anomalies, termination rates, and 1-year outcomes across Denmark, Sweden, Finland, and a large prenatal cohort from China. It is useful for quickly comparing population-based burden and prognosis across settings.

9.2 Inheritance patterns

Omphalocele is best conceptualized as heterogeneous: - Many cases are sporadic, - A substantial subset relates to aneuploidy/chromosomal abnormalities and syndromic disorders, - Some non-isolated cases may be attributable to monogenic variants detected by WES in selected contexts. (que2023ultrasonographiccharacteristicsgenetic pages 1-2, que2023ultrasonographiccharacteristicsgenetic pages 4-6)

10. Diagnostics

10.1 Prenatal diagnosis

Prenatal ultrasound is a principal diagnostic modality; in the China cohort, prenatal ultrasound diagnosis supported classification into isolated vs non-isolated omphalocele and guided subsequent genetic testing and counseling. (que2023ultrasonographiccharacteristicsgenetic pages 1-2, que2023ultrasonographiccharacteristicsgenetic pages 4-6)

10.2 Postnatal evaluation for associated anomalies

Because associated anomalies are frequent and prognostically important, registry and cohort evidence supports comprehensive evaluation. For example, a postnatal cohort emphasized routine screening for additional anomalies; a center implemented routine cardiac ultrasound screening since 2018 in children with omphalocele. (pijpers2023additionalanomaliesin pages 2-4)

10.3 Genetic testing

Evidence supports routine karyotype + CMA and escalation to WES if first-line tests are normal, particularly in non-isolated cases. (que2023ultrasonographiccharacteristicsgenetic pages 1-2, namat2025omphaloceleandassociated pages 11-13)

11. Outcome / Prognosis

11.1 Key prognostic determinants

Across multiple sources, prognosis is driven primarily by associated anomalies and chromosomal/syndromic diagnoses, rather than the abdominal wall defect alone. (malhotra2023enhancingomphalocelecare pages 6-7, laustenthomsen2024omphaloceleprevalenceand pages 1-2)

11.2 Survival statistics

11.3 Morbidity and quality of life

Long-term morbidity includes cardiopulmonary complications, feeding problems, and neurodevelopmental sequelae particularly in giant omphalocele survivors, as synthesized in consensus/review sources. (saxena2025europeanpaediatricsurgeons pages 8-9, namat2025omphaloceleandassociated pages 11-13)

12. Treatment

12.1 Management goals

A major surgical principle is to achieve safe reduction/closure while avoiding pathologic increases in intra-abdominal pressure (abdominal compartment syndrome physiology). (namat2025omphaloceleandassociated pages 11-13)

12.2 Current applications and real-world implementations (2023–2024)

Recent clinical implementation studies highlight non-traditional strategies alongside standard primary/staged closure:

A) Traction-assisted staged closure (fasciotens®Pediatric) A multicenter prospective series (2022–2023 recruitment period) achieved complete fascial closure in 16/16 patients (10 giant omphalocele, 6 gastroschisis), with median closure times of 7 days (giant omphalocele) and 5 days (gastroschisis), and reported no SSI or abdominal compartment syndrome; no hernias were observed at median 12-month follow-up. (ziegler2024useofa pages 1-2, ziegler2024useofa pages 5-7)

A table image summarizing outcomes is available from the paper (Table 3). (ziegler2024useofa media f0a1df53)

B) Awake graduated compression dressings for exomphalos major A 2024 case series (n=4) started bedside compression dressings on days 1–3 of life, achieved full feeds in ~1 week on average, limited parenteral nutrition, and enabled delayed repairs without patch and without prolonged ventilation. (widatella2024acaseseries pages 1-3)

12.3 Treatment strategy summary (with MAXO suggestions)

A treatment table (knowledge-base ready) is embedded below.

Table (click to expand)
Strategy Suggested MAXO term(s) Indication / selection factors Key outcomes / complications Real-world implementation notes Sources
Immediate primary closure MAXO: surgical repair; primary closure of abdominal wall defect Best suited to small omphaloceles or cases without major viscero-abdominal disproportion and without prohibitive cardiopulmonary risk; goal is definitive early closure while avoiding dangerous rise in intra-abdominal pressure Preferred when feasible, but urgent reduction can precipitate abdominal compartment syndrome with reduced cardiac output, splanchnic hypoperfusion, lactic acidosis, renal failure, intestinal ischemia, and hypoventilation; prognosis strongly influenced by associated anomalies rather than closure alone Standard neonatal surgical approach in many centers for smaller defects; in the Amsterdam cohort, primary closure was performed in 33/40 (82.5%) omphalocele patients overall, though this cohort included both minor and giant cases (malhotra2023enhancingomphalocelecare pages 6-7, pijpers2023additionalanomaliesin pages 2-4) (malhotra2023enhancingomphalocelecare pages 6-7, pijpers2023additionalanomaliesin pages 2-4)
Staged reduction with silo / delayed primary closure MAXO: staged surgical closure; silo placement; delayed primary closure Used when primary closure is unsafe because of large defect, liver herniation, or marked viscero-abdominal disproportion; also used to reduce risk of cardiorespiratory compromise EUPSA summary of giant omphalocele literature reported early closure strategies used patches more often (44% vs 17% for delayed), with mortality 8% for early closure overall versus delayed subgroups: simple 18%, composite 0%, patch 63%; intervention-related complications include infection, small-bowel obstruction, abdominal compartment syndrome, and rare vascular kinking of portal/hepatic vessels Widely used conventional option; silastic/synthetic silo allows gradual bedside or OR reductions before fascial closure; literature is heterogeneous and outcomes depend heavily on defect severity and associated anomalies (saxena2025europeanpaediatricsurgeons pages 7-8, saxena2025europeanpaediatricsurgeons pages 8-9, malhotra2023enhancingomphalocelecare pages 6-7)
Traction-assisted staged closure (fasciotens® Pediatric) MAXO: traction-assisted closure; staged surgical closure Consider for giant omphalocele when primary closure is not amenable but early neonatal fascial closure is desired; aims to enlarge abdominal domain and enable tension-less fascial approximation Prospective multicenter series: 10 giant omphalocele + 6 gastroschisis; complete fascial closure in all; median time to closure 7 days for giant omphalocele (range 4–22); 2 traction-suture tear-outs and 1 skin dehiscence; no SSI, no abdominal compartment syndrome, and no ventral/umbilical hernia after median 12-month follow-up Requires specialized device, fascial traction sutures/mesh anchoring, and NICU/surgical expertise; practical recommendations include direct fascial exposure and traction around ~30% body weight (ziegler2024useofa pages 5-7, ziegler2024useofa pages 1-2, ziegler2024useofa pages 4-5, ziegler2024useofa pages 8-9)
Conservative delayed closure / “paint-and-wait” MAXO: conservative management; topical medication administration; delayed closure Recommended when anatomical constraints or high surgical risk preclude primary closure, especially giant omphalocele with liver exteriorization and/or pulmonary hypoplasia/pulmonary hypertension EUPSA recommends paint-and-wait when primary closure is not feasible; common agents include povidone-iodine and silver sulfadiazine, with Manuka honey of emerging interest; consensus on dosing/duration remains unclear; avoids early compartment syndrome risk but requires prolonged epithelialization and later ventral hernia management Standard non-operative pathway in many centers for severe giant omphaloceles; later definitive ventral hernia repair often needed; literature lacks standardized protocols (namat2025omphaloceleandassociated pages 11-13, saxena2025europeanpaediatricsurgeons pages 7-8, saxena2025europeanpaediatricsurgeons pages 8-9, malhotra2023enhancingomphalocelecare pages 6-7)
Awake graduated compression dressing MAXO: compression therapy; staged reduction; enteral feeding support Alternative bedside strategy for exomphalos major when avoiding repeated general anesthesia/ventilation is desirable and sac integrity permits gradual reduction Case series of 4 neonates: defects 5–7 cm; dressings started days 1–3; average time to full feeds 1 week; only 1 infant required parenteral nutrition; 3 underwent repair at 2–16 weeks, 1 at 1 year; none required patch repair or prolonged ventilation Applied at bedside in neonatal ward while infants are awake; parents can be trained for dressing changes and some infants discharged home during compression period; facilitates simultaneous early enteral feeding (widatella2024acaseseries pages 1-3, widatella2024acaseseries pages 5-6, widatella2024acaseseries pages 3-5)
Biological mesh for early closure MAXO: surgical implantation of biological prosthesis; patch repair Considered when early closure is pursued but native fascial closure is not yet possible; preferred over synthetic material in EUPSA guidance for early repair EUPSA consensus states early closure favors biological meshes and suggests lower morbidity/mortality than synthetic materials; however, delayed patch closure had the highest mortality in pooled comparisons (63%), likely reflecting the sickest/severest defects Choice depends on center experience, contamination risk, tissue availability, and defect severity; biologic material may integrate better than synthetic mesh (saxena2025europeanpaediatricsurgeons pages 7-8, saxena2025europeanpaediatricsurgeons pages 8-9)
Component separation / native-tissue delayed closure MAXO: component separation technique; delayed abdominal wall reconstruction Used for delayed reconstruction after conservative management or staged reduction, particularly when native tissue closure is possible and patch avoidance is desired EUPSA notes delayed closure appears most effective using native tissues; complications are generally intervention-related and long-term multidisciplinary follow-up is needed; may reduce need for permanent prosthetic material Often part of later ventral hernia repair after paint-and-wait or delayed management; timing individualized based on growth, respiratory status, and abdominal domain (saxena2025europeanpaediatricsurgeons pages 7-8, saxena2025europeanpaediatricsurgeons pages 8-9)

Table: This table summarizes current management options for omphalocele, especially giant omphalocele, with indications, outcomes, complications, and suggested MAXO annotations. It highlights how treatment choice is driven mainly by defect size, viscero-abdominal disproportion, and cardiopulmonary risk.

13. Prevention

No specific primary prevention interventions with strong causal evidence were identified in the retrieved corpus. However, secondary prevention through prenatal detection is widely implemented and substantially influences observed live-birth prevalence because termination rates are high in many settings. (fogelstrom2021omphalocelenationalcurrent pages 1-2, raitio2021omphaloceleinfinland pages 5-9)

14. Other Species / Natural Disease

No veterinary/natural disease evidence was retrieved in the tool-accessible corpus.

15. Model Organisms

No model organism studies specific to omphalocele mechanisms were retrieved in the tool-accessible corpus.

Limitations of this report (evidence gaps)

  • MONDO/Orphanet/MeSH/OMIM IDs were not accessible via the current tool evidence and should be appended from ontology databases.
  • Evidence for environmental causes/protective factors, gene–environment interactions, multi-omics profiling, model organisms, and standardized global guidelines was limited in the retrieved corpus.
  • The EUPSA consensus statement quantitative table data were extractable via text evidence but the article’s figures/tables were not accessible for image extraction in this run due to document retrieval limitations. (saxena2025europeanpaediatricsurgeons pages 7-8)
