Ogilvie syndrome

Documented acute dilatation

Record the imaging interpretation, affected segments and baseline comparison supporting an acute colonic presentation.

1. Which colonic segments are dilated, and what imaging report documents this? measurement
2. What establishes an acute change rather than longstanding dilatation or chronic pseudo-obstruction? boundary

Supported pseudo-obstruction assessment

Connect the diagnostic assertion to investigations, unresolved alternatives and the issuing body's dated guidance.

1. How were an obstructing lesion and volvulus excluded, and what uncertainty remains? boundary
2. What evidence distinguishes this presentation from generalised ileus or toxic megacolon? boundary
3. Who asserted the diagnosis, using which diagnostic guidance and terminology release? provenance

Episode context

Link recent surgery, trauma or acute illness and record age and care setting; these are recognised contexts, not diagnostic requirements. [ASCRS guideline, 2021](https://www.ascrsu.com/ascrs/repview?name=2_2851057_PDF&type=784-113)

1. Which illnesses, operations or injuries preceded the bowel changes, and by how long? provenance
2. Does the evidence being applied cover this person's age group and clinical setting? boundary

Contributor attribution

Record medication exposures, electrolyte results and other proposed contributors with timing and confidence.

1. Which medication exposures or physiological disturbances are proposed contributors, and what supports each attribution? provenance
2. Which contributors have been addressed, and how did the episode change afterward? action

Diameter and duration trajectory

Pair cecal measurements with observation times, estimated onset and symptom changes.

1. What are the latest and previous cecal diameters, and are their measurement methods comparable? measurement
2. How long has dilatation persisted, and how uncertain is its onset? measurement
3. How have distension, pain, vomiting and stool or flatus passage changed between assessments? measurement

Urgent complication assessment

Record examination, physiological, laboratory and imaging evidence concerning ischaemia or perforation, with review status.

1. What current findings support or weaken concern for ischaemia, perforation or peritonitis? measurement
2. Does the assessment require urgent surgical review under the selected guideline, and has that review occurred? action

Pathway eligibility

Document the clinician's assessment of supportive care, neostigmine, colonoscopic decompression or surgical management, including contraindications and monitoring requirements. [ASCRS guideline, 2021](https://www.ascrsu.com/ascrs/repview?name=2_2851057_PDF&type=784-113)

1. Which pathway was selected, under which guideline version, and what findings justify it? action
2. What contraindications, monitoring needs or resource constraints affect the proposed intervention? action
3. What response deadline or deterioration finding triggers reassessment of this choice? action

Documented episode outcome

Record symptom and imaging response, adverse events and the evidence used to close or reopen an episode.

1. What objective and symptomatic changes followed treatment, and when were they measured? measurement
2. What documented criteria establish resolution rather than temporary improvement? definition
3. If dilatation returns, what supports recurrence after resolution rather than persistence or an underlying chronic disorder? boundary
