I now have solid clinical material from two textbooks. Let me compile the full format for you.

Pediatric GI Case Format - Complete History Taking with Clinical Reasoning

Based on: Textbook of Family Medicine 9e and Tintinalli's Emergency Medicine

SECTION 1: IDENTIFICATION & DEMOGRAPHICS

Question	Why You Ask It
Name, age, sex, weight	Age is the single most important filter - differential diagnosis for vomiting/abdominal pain is completely different by age (newborn vs toddler vs school-age). Weight tracks nutritional status and calculates drug doses.
Who brought the child	Helps gauge reliability of history; grandparent may not know feeding details, while parent knows better.
Referred or self-referred	Indicates severity perception and access to prior care.

SECTION 2: PRESENTING COMPLAINT (PC) & HISTORY OF PRESENTING ILLNESS (HPI)

For Any GI Complaint - Use SOCRATES + WHY

A. ABDOMINAL PAIN

Question	Why You Ask It
Site - Where does it hurt? Point with one finger.	Localisation guides anatomy. RIF = appendix/terminal ileum/ovary. Periumbilical = small bowel/early appendicitis. Epigastric = stomach/duodenum/pancreatitis. Diffuse = peritonitis, mesenteric adenitis, functional pain.
Onset - Did it start suddenly or gradually?	Sudden severe onset = perforation, volvulus, intussusception (surgical emergency). Gradual = inflammatory (appendicitis early), IBD, constipation.
Character - Crampy/colicky or constant?	Colicky (comes and goes in waves) = hollow viscus obstruction - bowel, biliary, ureteric. Constant = peritoneal involvement (somatic pain).
Radiation - Does the pain go anywhere else?	Biliary pain radiates to right shoulder (diaphragm irritation). Renal pain to groin. Testicular torsion pain to abdomen.
Associated symptoms - Fever, vomiting, diarrhea, constipation?	Fever + RIF pain = appendicitis until proven otherwise. Vomiting before pain = often medical. Pain before vomiting = often surgical. Obstipation = bowel obstruction.
Timing - How long? Getting better or worse?	Appendicitis typically worsens over 12-24 hours. Functional/recurrent pain in school-age children follows a pattern - often 3+ episodes over 3 months.
Exacerbating/relieving factors - What makes it worse? Better?	Pain worse with movement = peritonism. Relieved by defaecation = large bowel origin. Worse with eating = peptic ulcer, malabsorption.
Severity - Pain score 0-10 (use faces scale for younger children)	Anchors severity and helps monitor change over time. Functional pain is rarely score 10.

B. VOMITING

Question	Why You Ask It
When did it start? Acute or recurrent?	Acute = infection, obstruction, metabolic. Recurrent since infancy = GERD. Recurrent in school-age = cyclic vomiting syndrome, migraine, psychogenic.
How many times per day?	Quantifies severity and dehydration risk. >6-8 episodes/day = high risk of dehydration in infants.
What does the vomit look like?	This is the most critical vomiting question: Bilious (green) = obstruction DISTAL to the ampulla of Vater - malrotation with volvulus until proven otherwise (surgical emergency in neonate). Bloody = oesophagitis, Mallory-Weiss tear, varices. Projectile, non-bilious in infant 2-8 weeks = pyloric stenosis (forceful, like "shot across the room"). Undigested food = achalasia, proximal obstruction. Clear/mucoid = non-specific.
Does vomiting come before or after pain?	Vomiting before pain = gastroenteritis (medical). Pain before vomiting = appendicitis, obstruction (surgical). This is a key surgical vs medical discriminator.
Is the child able to keep anything down?	Determines hydration strategy - oral vs IV rehydration.
Is the child a "happy spitter" or distressed?	Happy infant who vomits but gains weight well = uncomplicated GERD (no investigation needed). Distressed infant = workup required.
Any blood or coffee-ground material?	Upper GI bleed. Coffee-ground = slow bleed, oxidized blood. Fresh red blood = active bleed. Both need urgent assessment.

C. DIARRHEA

Question	Why You Ask It
When did it start? Sudden or gradual?	Abrupt onset = infectious (viral > bacterial). Gradual onset over weeks = malabsorption (coeliac, IBD, cow's milk protein intolerance).
How many stools per day? What's normal for this child?	Context matters - exclusively breastfed infants may have 8-10 loose stools/day normally. A toddler having 6 watery stools/day is abnormal.
Describe the stool - colour, consistency, blood, mucus, smell	Watery = secretory (viral, toxin-mediated). Fatty/greasy/pale/foul-smelling = steatorrhoea = fat malabsorption (coeliac, cystic fibrosis, pancreatic insufficiency). Bloody + mucus = dysentery = bacterial (Salmonella, Shigella, Campylobacter, E. coli O157) or IBD. Bloody without mucus in infant = intussusception, necrotising enterocolitis. Currant-jelly stool = intussusception (classic - blood + mucus mixed). Black/tarry (melena) = upper GI bleed.
Nocturnal diarrhea?	Functional/IBS pain and diarrhea does NOT wake a child from sleep. Organic disease (IBD, infection) often does. This is a high-yield differentiating question.
Is the child passing urine? How often?	Assesses dehydration. Normal urine output = 1 mL/kg/hr in children. Decreased urine output = significant dehydration requiring urgent rehydration.
Any tenesmus (straining, urgency, feeling of incomplete emptying)?	Tenesmus = rectal/colonic inflammation - points to dysentery or proctocolitis.
Contact history or travel?	Daycare/school cluster = norovirus, rotavirus, Shigella. Recent travel to endemic area = Giardia, typhoid, cholera, amoeba.
What has the child been eating/drinking?	Raw meat/eggs = Salmonella, Campylobacter. Unpasteurised milk/juice = E. coli O157, Listeria. Antibiotics recently = C. difficile-associated diarrhea.

D. RECTAL BLEEDING

Question	Why You Ask It
Fresh red blood or dark/altered blood?	Fresh red = lower GI (anal fissure most common in infants/toddlers, polyp, Meckel's, intussusception, IBD). Dark blood = upper GI source.
Blood on surface of stool or mixed in?	On surface/paper only = anorectal (fissure, haemorrhoid). Mixed throughout = colonic source (polyp, IBD, infection).
Associated with hard stool and pain on defaecation?	Anal fissure - the most common cause of rectal bleeding in children. Child cries when passing stool, blood on surface, constipation history.
Painless rectal bleeding?	Painless fresh bleeding = Meckel's diverticulum (ectopic gastric mucosa causes peptic ulceration). Classically in child <2 years with large painless bleed.
Age of child?	Age helps narrow diagnosis: Neonate = haemorrhagic disease of newborn, NEC, swallowed maternal blood. Infant = intussusception, anal fissure. Toddler = Meckel's, polyp, fissure. School-age = IBD, polyp, infectious colitis.

E. JAUNDICE

Question	Why You Ask It
Age at onset of jaundice?	Neonatal jaundice appearing within 24 hours = haemolytic (Rh/ABO incompatibility - pathological, not physiological). Day 2-7 = physiological jaundice (normal). Persisting >2 weeks = investigate (biliary atresia, hypothyroidism, infection). In older child = hepatitis, haemolysis, Gilbert's.
Is the jaundice isolated or with pale stools and dark urine?	Pale stools + dark urine + jaundice = obstructive (conjugated) jaundice = biliary atresia, choledochal cyst, hepatitis. This triad demands urgent imaging. Jaundice without pale stools = haemolytic or Gilbert's (unconjugated).
Itching (pruritus)?	Cholestasis causes bile salt deposition in skin = intense itch. Confirms obstructive picture.
Fever + jaundice?	Infectious hepatitis (hepatitis A most common in children), cholangitis.
Contact with jaundiced person? Vaccination status?	Hepatitis A - faecal-oral, common in unvaccinated children in endemic areas.

SECTION 3: FEEDING & NUTRITIONAL HISTORY

Question	Why You Ask It
Breastfed or formula fed? (for infants)	Breastfed = lower infection risk, different stool pattern (yellow, seedy, frequent). Formula type matters - cow's milk formula can cause allergy/intolerance presenting as vomiting, diarrhea, blood in stool.
When were solids introduced?	Gluten introduction = triggers coeliac in susceptible children (typically presents months after wheat started).
Appetite - normal, increased, decreased?	Decreased appetite + weight loss = organic disease (IBD, coeliac, malignancy). Increased appetite + weight loss = malabsorption (coeliac, CF).
Any specific food avoidances or reactions?	Child may have subconsciously learnt to avoid trigger foods (e.g., dairy in lactose intolerance, wheat in coeliac).
Weight trend - gaining, static, or losing?	Weight loss or failure to thrive is the single most important red flag in paediatric GI - it mandates thorough investigation regardless of diagnosis.

SECTION 4: BOWEL HABIT HISTORY

Question	Why You Ask It
Normal stool frequency and consistency?	Baseline varies widely by age and diet. Breastfed infant: multiple loose stools/day (normal). Formula-fed: 1-2/day. School-age: 1-2/day. Anything outside baseline needs context.
Has stool pattern changed?	Change in bowel habit in a child = alarm symptom requiring investigation (IBD, Hirschsprung's, malignancy, coeliac).
Hard stools, straining, pain on defaecation?	Functional constipation is extremely common - accounts for most rectal bleeding in children via fissures. Understanding constipation explains a huge number of paediatric abdominal presentations.
Soiling/encopresis?	Overflow incontinence from severe constipation. Child with chronic constipation develops a loaded colon, liquid stool leaks around the impacted mass - looks like diarrhea but is constipation. KEY distinction.
Ribbon/pencil stools?	Narrow caliber stools = colorectal narrowing (stricture, mass, Hirschsprung's long segment).

SECTION 5: SYSTEMIC & ASSOCIATED SYMPTOMS

Question	Why You Ask It
Fever?	Infective GI pathology, appendicitis, IBD flare. Fever >38.5°C with diarrhea and blood = dysentery, treat empirically if toxic.
Weight loss or failure to thrive?	RED FLAG - always document weight trend. IBD, coeliac, malignancy, chronic infection (TB), liver disease.
Mouth ulcers?	Aphthous ulcers = Crohn's disease (can present years before bowel symptoms).
Skin rash?	Dermatitis herpetiformis = coeliac. Erythema nodosum, pyoderma gangrenosum = IBD. Jaundice with purpura = liver failure.
Joint pains (arthralgia/arthritis)?	Extra-intestinal manifestation of IBD - can precede bowel symptoms. Also seen in reactive arthritis post-infectious diarrhea (Reiter's syndrome).
Eye symptoms (redness, pain)?	Uveitis, episcleritis = IBD extra-intestinal manifestation.
Urinary symptoms?	Urinary tract infection commonly presents as abdominal pain in children (especially girls). Always ask - do NOT assume all abdominal pain is GI. Renal calculi cause severe loin-to-groin colicky pain with haematuria.
Respiratory symptoms?	Recurrent chest infections + diarrhea + failure to thrive = cystic fibrosis. Right lower lobe pneumonia can mimic RIF pain (diaphragmatic peritoneum).
Headache with vomiting?	Raised intracranial pressure presents as vomiting (especially morning vomiting without nausea, with headache = red flag for CNS cause).
Menstrual history (post-pubertal girls)?	Ectopic pregnancy, ovarian torsion, mittelschmerz. Always ask LMP in adolescent girls with abdominal pain.

SECTION 6: PAST MEDICAL HISTORY

Question	Why You Ask It
Previous similar episodes?	Recurrent abdominal pain (3+ episodes over 3 months) = functional pain syndrome or IBD. Recurrent intussusception in infant = Henoch-Schonlein Purpura, lymphoma as lead point.
Previous abdominal surgery?	Adhesions = most common cause of bowel obstruction in a child with prior surgery. Stoma presence changes GI anatomy completely.
Previous GI investigations (scopes, imaging)?	Avoids repeating tests; gives baseline for comparison.
Chronic conditions - coeliac, IBD, CF, liver disease?	Contextualises current presentation as flare vs. new pathology.
Jaundice in newborn period? How treated?	Neonatal hyperbilirubinaemia history relevant to haemolytic conditions, biliary atresia workup.

SECTION 7: DRUG & ALLERGY HISTORY

Question	Why You Ask It
Current medications?	NSAIDs = peptic ulcer, GI bleed. Antibiotics = C. difficile, antibiotic-associated diarrhea, change in gut flora. Steroids = mask peritonism (pain absent despite serious pathology). Metformin = diarrhea. Iron supplements = constipation, black stools (mimics melena).
Recent antibiotics?	C. difficile in children is increasing. Prior antibiotic use is mandatory history in any child with diarrhea.
Food allergies or intolerances?	Cow's milk protein allergy in infants = vomiting, diarrhea, blood in stool. Lactose intolerance = bloating, diarrhea, cramping after dairy.
Drug allergies?	Before prescribing any treatment.

SECTION 8: FAMILY HISTORY

Question	Why You Ask It
IBD in family?	Crohn's and UC have strong genetic component. First-degree relative with IBD = 10x increased risk.
Coeliac disease in family?	HLA-DQ2/DQ8 has familial clustering.
Liver disease, jaundice, gallstones?	Familial hyperbilirubinaemia (Gilbert's, Dubin-Johnson). Gallstones in children often linked to haemolytic conditions (sickle cell, spherocytosis) - strong family history.
Cystic fibrosis carrier status?	Autosomal recessive - ask about both parents.
Polyposis syndromes?	FAP, Peutz-Jeghers - familial colorectal polyps presenting with GI bleeding in children.
Consanguinity?	Increases risk of autosomal recessive conditions (CF, metabolic disorders, Hirschsprung's).

SECTION 9: SOCIAL & DEVELOPMENTAL HISTORY

Question	Why You Ask It
School attendance/performance?	Functional abdominal pain classically causes school avoidance. "Stomach ache every Monday morning" = psychosomatic, school refusal.
Stressors - new school, family change, bullying?	Functional GI disorders (recurrent abdominal pain, IBS) in children are heavily linked to psychological stress. You CANNOT diagnose functional pain without excluding organic disease, but stress history supports it.
Developmental milestones normal?	Developmental regression + GI symptoms = metabolic/systemic disease.
Immunisation status?	Rotavirus vaccination - reduces severity of gastroenteritis. Hepatitis A, B vaccination - prevents viral hepatitis. Unvaccinated child with jaundice = hepatitis A until proven otherwise.
Daycare/school contact with sick children?	Daycare clusters = norovirus, rotavirus, Giardia, Shigella. High yield epidemiological question.
Travel history?	Giardia, typhoid, hepatitis A, amoebic dysentery. Ask where, when, water source, food eaten.

SECTION 10: REVIEW OF RED FLAGS (Always Ask These)

These questions directly change management urgency:

Red Flag	Question to Ask	Clinical Significance
Bilious vomiting	"Is the vomit green?"	Surgical emergency (obstruction below ampulla) until proven otherwise - especially in neonates
Bloody stool	"Any blood in the stool?"	Wide differential - requires urgent workup
Severe dehydration	"Is the child passing urine? Tears when crying? Eyes sunken?"	Determines need for IV fluids
Failure to thrive	"Has weight been normal? Plotted on growth chart?"	Chronic organic disease
Nocturnal symptoms	"Does pain/diarrhea wake the child from sleep?"	Rules out functional disease - organic until proven otherwise
Weight loss	"Has the child lost weight recently?"	IBD, malignancy, coeliac, chronic infection
Persistent/progressive pain	"Is it getting worse over hours?"	Appendicitis, obstruction, volvulus
Age <3 months + vomiting	-	Any cause of vomiting in a neonate/young infant = investigate fully

QUICK SUMMARY TEMPLATE (For Case Presentation)

[Child's name], a [age]-year-old [male/female], presented with [main complaint] 
for [duration]. The [complaint] is described as [character], located at [site], 
[radiating to], [onset pattern], scored [X/10], [exacerbating/relieving factors].

Associated symptoms include: [fever / vomiting / diarrhea / weight loss / etc.]

Stool: [frequency / consistency / colour / blood / mucus]
Vomit: [frequency / character - bilious? bloody? projectile?]

Feeding: [breastfed/formula/solids - normal intake? reduced?]
Weight trend: [gaining / static / losing / FTT]

Past history: [prior episodes / surgery / conditions]
Medications: [antibiotics / NSAIDs / other]
Family history: [IBD / coeliac / CF / liver disease]
Social: [school attendance / stress / contacts / travel / immunisation status]

Red flags present/absent: bilious vomiting / bloody stool / dehydration signs / 
nocturnal symptoms / weight loss / failure to thrive

Key Clinical Principles to Remember:

Age is everything in pediatric GI - the differential completely shifts at each age group
Bilious vomiting in any child = surgical emergency until proven otherwise
Pain before vomiting = surgical; vomiting before pain = medical
Nocturnal GI symptoms = organic disease (rules out functional)
Weight loss/FTT = always investigate fully regardless of suspected diagnosis
Constipation with soiling ≠ diarrhea - overflow incontinence is a classic trap
Urinary symptoms always ask - UTI mimics GI pain in children
