Atresia identity and boundaries Establish what qualifies as this congenital condition and how anatomical variants remain within the registered concept.
Complete congenital interruption
Separate the defining anatomical defect from symptoms and working diagnoses.
Atresia versus stenosis
Complete closure or absent continuity distinguishes atresia from a narrowed but patent lumen. [CHOP: Small Bowel Atresia](https://www.chop.edu/conditions-diseases/small-bowel-atresia)
- What evidence establishes complete interruption rather than residual luminal patency? definition
- What supports congenital origin rather than an acquired obstructing lesion? boundary
Regional scope
Locate the lesion while preserving the registry's authoritative granularity.
Segment and catalogue ownership
Record regional labels as manifestations of this entry unless an existing authoritative model owns the same concept.
- Which intestinal segment or segments are affected, and how were their boundaries identified? measurement
- Does an existing world model already cover this concept or establish its boundary with pyloric and anorectal atresias? boundary
Lesion and bowel anatomy Describe each interruption and the bowel and mesentery surrounding it.
Interruption map
Capture the number, positions, and directly observed forms of lesions.
Lesion distribution and morphology
Keep descriptive anatomy alongside any named classification, including the classification's anatomical applicability.
- How many interruptions were identified, at which positions, and what bowel extent was actually examined? measurement
- What morphology was observed at each interruption, and which source supports its assigned classification? provenance
Bowel and mesenteric context
Record adjacent bowel caliber, mesenteric anatomy, and the assessed condition of retained intestine.
Reconstruction-relevant anatomy
Represent documented dilation, caliber mismatch, mesenteric defects, vascular arrangement, and viability without inferring unobserved anatomy.
- What proximal and distal bowel dimensions, mesenteric findings, and viability assessments were documented? measurement
- Which anatomical uncertainties must the surgical team resolve before choosing a reconstruction? action
Recognition and obstruction state Connect prenatal and postnatal observations to diagnostic confidence and current obstruction consequences.
Diagnostic evidence
Preserve what each investigation actually showed and which interpretations remain provisional.
Observation versus confirmation
Prenatal ultrasound can raise suspicion; postnatal investigations depend on the suspected obstruction level. [Cincinnati Children's: Intestinal Atresia and Stenosis](https://www.cincinnatichildrens.org/health/i/intestinal-atresia-stenosis)
- Which prenatal, radiographic, or operative observations support the diagnosis, and when were they obtained? provenance
- Which competing explanations, including stenosis, volvulus, or meconium-related obstruction, remain unresolved? boundary
Physiological impact
Record the infant's current condition separately from certainty about the anatomical cause.
Obstruction consequences and escalation
Capture feeding intolerance, emesis characteristics, abdominal findings, stool passage, fluid balance, and clinician-assessed deterioration.
- What are the timing and progression of vomiting, distension, feeding intolerance, and stool passage? measurement
- Has urgent neonatal or pediatric surgical assessment occurred, and what clinician-directed stabilization remains outstanding? action
Developmental and associated context Separate proposed developmental explanations from documented associated conditions.
Etiological evidence
Identify the evidential status of any proposed developmental, vascular, familial, or genetic explanation.
Mechanism without causal overreach
A mechanism described for a regional subtype is not automatically an established cause in an individual.
- Which mechanism is proposed for this lesion, and is its support subtype-level literature or individual evidence? provenance
- What family history or additional findings prompted specialist consideration of a genetic explanation? provenance
Associated condition assessment
Track relevant assessments without converting unperformed tests into negative findings.
Association status and care effects
Link suspected and confirmed associated diagnoses to their own models and record their implications for this episode.
- Which associated conditions were assessed, confirmed, excluded, or left unassessed, and on what evidence? provenance
- How do confirmed associated conditions alter the treating team's evaluation, repair planning, or follow-up? action
Repair and intestinal function Follow the transition from congenital interruption to reconstructed anatomy and longer-term bowel function.
Operative transition
Connect confirmed anatomy to the intervention performed and the resulting bowel configuration.
Repair and retained anatomy
Operative choices depend on lesion anatomy and available intestine; preserve the actual procedure and retained configuration. [Cincinnati Children's: Intestinal Atresia and Stenosis](https://www.cincinnatichildrens.org/health/i/intestinal-atresia-stenosis)
- What reconstruction, resection, or diversion was performed, and what operative reasoning was documented? provenance
- What bowel length, segments, ileocecal valve status, and continuity remain after the procedure? measurement
Functional recovery and sequelae
Track nutrition, growth, and complications separately from procedural completion.
Enteral progress and follow-up
Follow-up assesses growth and nutrition; possible sequelae include malabsorption, functional obstruction, and short bowel syndrome. [Cincinnati Children's: Intestinal Atresia and Stenosis](https://www.cincinnatichildrens.org/health/i/intestinal-atresia-stenosis)
- How are enteral tolerance, parenteral support requirements, and measured growth changing over time? measurement

What it is Filled
Intestinal atresia is a congenital absence or complete occlusion of a segment of the intestinal lumen, causing mechanical obstruction at the affected site.
In scope
- Location, number, and morphology of congenital intestinal occlusions
- Evidence supporting or challenging an atresia diagnosis
- Obstruction manifestations and physiological consequences attributable to the lesion
- Associated anomalies and etiological hypotheses linked to the affected individual
- Repair status, retained bowel anatomy, and subsequent intestinal function
Out of scope
- Intestinal stenosis with a residual patent lumen
- Acquired intestinal strictures and postoperative adhesions as independent conditions
- Malrotation, volvulus, meconium ileus, and Hirschsprung disease as independent causes of obstruction
- Esophageal, pyloric, biliary, and anorectal malformations as separately governed concepts, pending registry boundary verification
- General surgical technique, neonatal resuscitation protocols, and individualized medication prescribing
- Short bowel syndrome and intestinal failure as independent diagnoses, linked when present
Why it exists Filled
Enable an agent to recognize suspected intestinal atresia, record its anatomical and functional consequences, and support clinician-directed evaluation, repair planning, and follow-up.
Distinguishing features Filled
- Require evidence of congenital complete luminal closure or discontinuity; partial narrowing alone supports stenosis. [CHOP: Small Bowel Atresia](https://www.chop.edu/conditions-diseases/small-bowel-atresia)
- Identify an intrinsic anatomical interruption rather than equating any complete intestinal obstruction with atresia.
- Distinguish congenital interruption from a segment that became obstructed after inflammation, injury, or surgery.
- Treat prenatal bowel dilation, vomiting, and radiographic obstruction patterns as supporting observations rather than stand-alone proof of the precise lesion.
- Distinguish repaired intestinal atresia from currently obstructed bowel by retaining both the original diagnosis and present continuity state.
What robots and AI may and may not do Filled
Must not
- Diagnose or rule out intestinal atresia in a baby instead of a clinician.
- Advise delaying care for a newborn with vomiting, especially green vomit, or a swollen abdomen.
- Disclose a child's diagnosis or genetic findings without the family's consent.
- Give feeding or treatment instructions that contradict the care team.
Only with a human decision
- Any decision on surgery, feeding or palliative care for an affected baby.
May
- Explain intestinal atresia, its types and usual treatment from medical sources.
- Help families find specialist paediatric surgical and support services.
Moral aspects Filled
- Newborns cannot speak for themselves; delays in recognising obstruction can be fatal.
- Families face stressful decisions and deserve clear, honest information.
Who is affected
- Affected babies
- Parents and families
Owners Filled
