Frame

Detailed

Frame the suspected pediatric intussusception presentation: age band (< 3 mo / 3-6 mo / 6 mo - 3 y / > 3 y / > 6 y) drives pretest probability + pathologic-lead-point consideration; 6 mo - 3 y is classic high-pretest cohort with highest enema-success rates; < 3 mo or > 6 y atypical → high lead-point suspicion. Duration of symptoms drives ischemia / perforation risk; > 24 h higher failure rate; > 48 h relative surgical indication.

Age band + duration tagged; pretest probability + lead-point suspicion framing set

Patient inputs (24)

Age band drives pretest probability + pathologic-lead-point consideration: < 3 mo or > 6 y atypical bands → high lead-point suspicion + surgical management preferred over enema; 6 mo - 3 y is classic-presentation band with highest enema-success rates

Weight-based dosing for all fluids + analgesia + sedation drugs; weight at presentation

Tachycardia + dehydration in prolonged duration; bradycardia + hypotension flags perforation/shock

Capillary refill > 3 s + mottling = dehydration / shock — pre-enema resuscitation required; severe dehydration is enema contraindication

Fever may suggest viral precipitant (URI ~ 30% precede) OR perforation with peritonitis; serial trend useful

Paroxysmal episodes drawing knees up = classic; constant pain may indicate ischemia / perforation

Sausage-shaped mass typically RUQ or epigastrium (Dance sign — empty RLQ); peritoneal signs (rigidity, guarding, rebound) → perforation; distention → progression

Viral URI precedes ~ 30% of cases; adenovirus most strongly associated (lymphoid hyperplasia of Peyer's patches → lead point); supports diagnosis in age-appropriate child

Transient post-vaccine intussusception risk window 1-21 d after dose 1 (~ 1 per 20-100K vaccinated); AAP statement continues to recommend vaccination — net benefit far exceeds risk; document for surveillance + family counseling

HSP-associated intussusception is typically ileoileal — surgical management more often than enema; document for rheumatology consult + management pivot

Recurrence ~ 10%; recurrent (≥ 2 episodes) raises pathologic lead-point suspicion (Meckel's, polyp, lymphoma) — evaluate via colonoscopy / Meckel's scan / contrast study after acute recovery

Currant-jelly stool (mucus + blood) is late finding (~ 60% of cases); occult blood on rectal exam more common early; normal stool does not rule out intussusception

Leukocytosis with left shift may suggest ischemia / perforation; baseline + serial

Electrolyte derangements from vomiting + dehydration; AKI from prolonged dehydration; baseline pre-sedation

First-line diagnostic — target sign on transverse / pseudokidney sign on longitudinal; sensitivity > 97%, specificity ~ 100% (ACR Appropriateness Criteria; Applegate 2005); bedside-accessible; no ionizing radiation

Plain KUB is non-diagnostic for intussusception itself but rules out free air pre-enema attempt; consider lateral decubitus view

Hypotension by age-appropriate threshold → surgical emergency contraindicates enema (perforation / shock concern)

Episodic lethargy ~ 10% atypical presentation; persistent lethargy raises concern for shock / sepsis

Duration > 24 h correlates with higher rates of bowel ischemia + enema failure + perforation; > 48 h is relative surgical indication

Pre-surgical type-and-screen if surgical management likely (failed enema, perforation, shock)

CF, prior abdominal surgery, intestinal duplication, polyposis syndromes (Peutz-Jeghers) raise pretest probability + lead-point likelihood

Reserved for post-recovery lead-point evaluation (Meckel's scan, MR enterography) in recurrent or atypical-age-band cases — NOT acute workup

Elevated lactate suggests bowel ischemia → relative surgical indication even pre-enema; > 4 mmol/L is concerning

Pneumatic (air) enema preferred over hydrostatic (Daneman 2003 retrospective; Sadigh AJR 2015 meta-analysis); BOTH diagnostic confirmation AND first-line therapy; reduction success ~ 80-90% in age-appropriate uncomplicated cases; complication rate ~ 1% perforation

Severity triggers (9)

9 need judgement
  • informationallife_threateningintussusception_with_perforation_or_shock
    Intussusception with perforation (free air on KUB, peritonitis on exam) OR hemodynamic compromise (hypotension by age threshold, tachycardia with poor perfusion, capillary refill > 3 s, mottling) OR shock (lactate ≥ 4, vasoactive medication required) — life-threatening surgical emergency; enema is CONTRAINDICATED; emergent operating room + ICU + IV fluid resuscitation + broad-spectrum antibiotics (ACR Appropriateness Criteria; SSC peds 2020 for shock physiology)

  • informationallife_threateningenema_complication_perforation
    Enema complication — perforation during pneumatic or hydrostatic enema (air or contrast extravasation on fluoroscopy, sudden hemodynamic decompensation, sudden abdominal distention) — life-threatening; immediately stop enema, decompress with needle aspiration if tension pneumoperitoneum, emergent OR + ICU + broad-spectrum antibiotics + vasoactive if shock; perforation rate ~ 1% per attempt with appropriate technique (ACR Appropriateness Criteria; Daneman 2003)
    Trigger could not be auto-evaluated — needs clinician judgement.
  • informationalsevereintussusception_age_under_3mo_or_over_6y
    Intussusception in atypical age band — < 3 months OR > 6 years — high index of suspicion for pathologic lead point (Meckel's diverticulum, intestinal polyp, lymphoma, duplication cyst, vascular malformation); surgical management preferred over enema in these cohorts; consider lead-point workup pre- or post-reduction depending on stability (ACR Appropriateness Criteria; Daneman 2003)

Auto-drafted A&P note

outpatient

Subjective

- Possible entry pathways: Child 6 mo - 3 y with paroxysmal abdominal pain in episodes lasting 5-30 min separated by quiet intervals (drawing knees up; inconsolable crying); classic intussusception ENTRY signal (ACR Appropriateness Criteria; AAP NEC-adjacent surgical-emergency guidance); Currant-jelly stool (mucus + blood) or bloody stool in child 6 mo - 3 y — pathognomonic but late finding (~ 60% of cases); LR+ ~ 10 for intussusception in age-appropriate cohort; Palpable sausage-shaped abdominal mass typically RUQ or epigastrium (Dance sign — empty RLQ) — third element of classic triad; LR+ ~ 8.

Objective

- No vitals, labs, or imaging entered for this encounter.

Assessment

**Intussusception (ileocolic / ileoileal) — pediatric** (peds.intussusception.v1).
Phenotype framing: Acute gastroenteritis (vomiting + diarrhea + dehydration but lacks paroxysmal pain pattern + currant-jelly stool); volvulus (especially midgut — bilious emesis in younger infant; upper-GI series); incarcerated inguinal hernia (palpable groin mass; surgical emergency in its own right); Meckel's diverticulum bleed (painless bleeding distinct from intussusception's painful presentation); appendicitis (older child > 5 y; RLQ pain; Alvarado / PAS score); HSP without intussusception (purpura + abdominal pain but no target sign on US); psychogenic abdominal pain (older child; lacks paroxysmal pattern + objective findings).
Scope: Frame the suspected pediatric intussusception presentation: age band (< 3 mo / 3-6 mo / 6 mo - 3 y / > 3 y / > 6 y) drives pretest probability + pathologic-lead-point consideration; 6 mo - 3 y is classic high-pretest cohort with highest enema-success rates; < 3 mo or > 6 y atypical → high lead-point suspicion. Duration of symptoms drives ischemia / perforation risk; > 24 h higher failure rate; > 48 h relative surgical indication.

Setting playbook (outpatient) — Post-discharge pediatrician + (if indicated) pediatric GI + pediatric surgery + rheumatology follow-up. Most intussusception cases recover completely with no long-term sequelae. Recurrent cases (≥ 2 episodes) require lead-point workup. HSP-associated cases require rheumatology follow-up.

10. continue HSP-specific corticosteroids if rheumatologist-managed prednisolone 1-2 mg/kg/day PO (max 60 mg/day) — per rheumatology PO daily — HSP-associated case with rheumatology guidance (Per pediatric rheumatology HSP-management protocol; not initiated by GI/surgical team)
11. NO ongoing antibiotic prophylaxis N/A N/A N/A — Uncomplicated post-recovery (No prophylactic antibiotics post-intussusception (ACR + AAP))
12. continue routine vaccines per ACIP including future rotavirus doses if applicable per ACIP age-based schedule PO (rotavirus) or IM (others) per ACIP — Routine well-child care (AAP statement — net benefit of rotavirus vaccination far exceeds individual intussusception risk; continue vaccination schedule unless contraindicated)

Non-pharmacologic actions:
- Family education reinforcement on return precautions
- Pediatric GI lead-point workup if recurrent (≥ 2 episodes): contrast study (upper-GI / small-bowel follow-through) + Meckel's scan (Tc-99m pertechnetate; sensitivity ~ 85% if age > 2 y) + colonoscopy if age-appropriate; MR enterography for polyposis syndromes (Peutz-Jeghers; familial polyposis)
- Pediatric surgery wound / scar / bowel function review post-op
- Rheumatology HSP management if applicable
- VAERS report if post-rotavirus-vaccine case (CDC surveillance)
- Routine well-child care + ongoing vaccination per ACIP
- Family caregiver psychosocial check at follow-up (acute illness in young child can be traumatic)

AVOID / contraindication checks:
- No enema attempt if perforation suspected or confirmed (free air on KUB, peritonitis on exam) (ACR Appropriateness Criteria)
- No enema attempt if shock or severe dehydration unresponsive to resuscitation (ACR Appropriateness Criteria)
- Do NOT attempt > 3 enema reductions (ACR Appropriateness Criteria + Daneman 2003)
- Pneumatic enema cap pressure at 120 mmHg (ACR Appropriateness Criteria)
- Hydrostatic enema cap at 1 m height of contrast column above patient (ACR)
- Pediatric sedation team must be in attendance for ketamine/dexmedetomidine procedural sedation (AAP pediatric sedation guidance)
- Pediatric surgery must be in attendance or immediately available during enema attempt (ACR Appropriateness Criteria; AAP)
- Ceftriaxone avoid under 28 days bilirubin displacement (FDA 2009; AAP Puopolo 2018 — applies only if neonatal presentation < 28 d which is atypical for intussusception but possible)
- Fluid bolus 20 mL per kg with reassessment pediatric AAP DDC (AAP pediatric resuscitation principles)

Monitoring

Regimen monitoring:
- continuous vitals during enema procedure with pediatric sedation team
- capnography during procedural sedation (AAP pediatric sedation guidance)
- serial abdominal exam q15 min during enema attempts
- post-enema vitals q1-2h × 6 h then q4h
- fluid balance + UOP q1h × 6 h post-enema
- pain re-assessment q2-4h with FLACC or age-appropriate scale
- serial diet advance from clear liquids → full liquids → soft → regular as tolerated
- family-bedside-instruction documentation on return precautions for recurrence signs

Setting (outpatient) monitoring:
- Pediatrician visit at 1-2 weeks, 4-6 weeks, then routine well-child care
- Pediatric GI at 4-6 weeks if recurrent / atypical-age for lead-point workup
- Pediatric surgery at 2-4 weeks post-op
- Rheumatology per HSP schedule
- Vaccination catch-up review at every well-child visit

Follow-up plan: Pediatrician follow-up within 1-2 weeks; return precautions reviewed with caregivers (recurrence signs: return of paroxysmal pain episodes, vomiting, bloody stool, lethargy — present to ED). Recurrent intussusception (≥ 2 episodes) → pediatric GI consult for lead-point workup: contrast study (upper-GI / small-bowel follow-through) + Meckel's scan (Tc-99m pertechnetate) + considered colonoscopy if age-appropriate; MR enterography for polyposis syndromes (Peutz-Jeghers). HSP-associated cases → rheumatology follow-up for HSP management beyond acute event. Rotavirus vaccine surveillance: report post-vaccine cases to VAERS (CDC surveillance) per AAP recommendation; family counseling that net benefit far exceeds individual case risk.
- Close-out criterion: Follow-up scheduled + return precautions delivered + lead-point workup queued if recurrent

Monitoring phase: Post-enema: vitals q1-2h × first 6 h then q4h; serial abdominal exams q2-4h watching for recurrence (return of paroxysmal pain pattern) or post-procedure complication; advance diet from clear liquids → full liquids → soft → regular as tolerated; family at bedside + bedside instructions on recurrence signs (return of pain episodes, vomiting, bloody stool). Post-surgical: standard post-op care + early ambulation + diet advance per surgeon; ileus monitoring; wound infection surveillance.

Disposition

Current setting: outpatient — Post-discharge pediatrician + (if indicated) pediatric GI + pediatric surgery + rheumatology follow-up. Most intussusception cases recover completely with no long-term sequelae. Recurrent cases (≥ 2 episodes) require lead-point workup. HSP-associated cases require rheumatology follow-up.

Disposition criteria:
- Sustained recovery — normal diet + bowel function + growth at age-appropriate baseline + no recurrent episodes in 6-12 mo + lead-point workup negative if performed + family demonstrating return-precaution knowledge

Escalation triggers (move to higher acuity):
- New episode of paroxysmal pain + vomiting + bloody stool → return to ED for repeat US + management (recurrent intussusception)
- Persistent post-op symptoms (pain, distention, abnormal bowel function) → urgent pediatric surgery + GI reassessment
- New palpable purpura + abdominal pain in age-appropriate child → HSP-associated suspicion; rheumatology + ED reassessment
- Family caregiver acute distress / PTSD symptoms after traumatic illness → mental-health referral

Earlier-Return Triggers

Return-precaution thresholds (watch for):
- [LIFE_THREATENING] Intussusception with perforation (free air on KUB, peritonitis on exam) OR hemodynamic compromise (hypotension by age threshold, tachycardia with poor perfusion, capillary refill > 3 s, mottling) OR shock (lactate ≥ 4, vasoactive medication required) — life-threatening surgical emergency; enema is CONTRAINDICATED; emergent operating room + ICU + IV fluid resuscitation + broad-spectrum antibiotics (ACR Appropriateness Criteria; SSC peds 2020 for shock physiology)
- [LIFE_THREATENING] Enema complication — perforation during pneumatic or hydrostatic enema (air or contrast extravasation on fluoroscopy, sudden hemodynamic decompensation, sudden abdominal distention) — life-threatening; immediately stop enema, decompress with needle aspiration if tension pneumoperitoneum, emergent OR + ICU + broad-spectrum antibiotics + vasoactive if shock; perforation rate ~ 1% per attempt with appropriate technique (ACR Appropriateness Criteria; Daneman 2003)
- [SEVERE] Intussusception in atypical age band — < 3 months OR > 6 years — high index of suspicion for pathologic lead point (Meckel's diverticulum, intestinal polyp, lymphoma, duplication cyst, vascular malformation); surgical management preferred over enema in these cohorts; consider lead-point workup pre- or post-reduction depending on stability (ACR Appropriateness Criteria; Daneman 2003)
