bowel obstruction
Let an agent explain bowel obstruction and its causes in neutral terms, relay symptoms, diagnosis and management in general from surgical sources, describe neonatal and special forms, and route anyone with symptoms to emergency care.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

What it is Filled
A mechanical or functional blockage of the small or large intestine that prevents the normal passage of contents, caused by adhesions, hernias, tumours, volvulus, intussusception, impaction or, in newborns, congenital atresia and conditions such as distal intestinal obstruction syndrome in cystic fibrosis, presenting with abdominal pain, distension, vomiting and constipation; bowel obstruction is a medical emergency that can lead to ischaemia and perforation and is managed with decompression, fluids and often surgery.
Why it exists Filled
Let an agent explain bowel obstruction and its causes in neutral terms, relay symptoms, diagnosis and management in general from surgical sources, describe neonatal and special forms, and route anyone with symptoms to emergency care.
Distinguishing features Filled
- Mechanical or functional block
- Pain, distension, vomiting
- Emergency
- Surgical management
What robots and AI may and may not do Filled
Must not
- Advise a person to treat a suspected obstruction at home with laxatives or enemas.
- Diagnose or rule out bowel obstruction from a description of symptoms.
- Delay a person's access to emergency care.
Only with a human decision
- Any decision about surgery or treatment.
May
- Explain causes and warning signs of bowel obstruction from medical sources.
- Urge a person with signs such as vomiting, distension and inability to pass stool or gas to seek urgent care.
Moral aspects Filled
- Bowel obstruction can become fatal within hours if left untreated.
- Infants and frail older people may not report symptoms clearly.
Who is affected
- Patients
- Newborns and their parents
- Carers of older people
Owners Filled
Steward
Nobody owns the condition; treating clinicians answer for care.

Plane XCT: no invented physical properties.
Recognition optional Filled
- Blockage of the intestine
- Small bowel obstruction, duodenal obstruction, volvulus, impaction, neonatal obstruction, distal intestinal obstruction syndrome

- describe special forms
- route to emergency care
Hazards and failure modes required Filled
- Delay leading to ischaemia and perforation
- Agents giving personal medical advice
- Confusing obstruction with ileus or constipation
Standards and interfaces required Filled
- Surgical society guidelines such as the Bologna guidelines for adhesive small bowel obstruction
- Emergency care protocols
Context of use required Filled
- Not applicable; a condition.
- small bowel obstruction from adhesions and hernias
- large bowel obstruction from tumours and volvulus
- duodenal obstruction
- intestinal volvulus and intussusception
- impaction including faecal impaction and distal intestinal obstruction syndrome
- neonatal bowel obstruction from atresia and other congenital causes

- How should surgical guidelines be linked?
- The registry entry has merged aliases naming causes and special forms; should they be split off?
