JULY 23, 2015
Learning Objectives1. To learn what aspects are important in medical history (present illness, past
family and personal history)
2. To establish a differential diagnosis for chronic abdominal pain
3. To recognize red flags in children with chronic abdominal pain
4. To review the management and basic investigations pertinent to children with chronic abdominal pain
Bidirectional Gut-Brain Axis
DefinitionChronic abdominal pain is defined as

B. 3 episodes of severe pain in a child >3 years old for atleast 3 months
C. Pain of more than 2 weeks duration
D. Severe pain in a child >3 years old for more than 3 months

Key History Questions Present Illness
◦ Description of pain- location, quality, frequency, duration and timing of episodes
◦ Associated symptoms
Past Family History◦ Recurrent abdominal pain◦ Peptic ulcer◦ IBS/IBD◦ Food allergies◦ Lactose intolerance◦ Gall bladder disease
◦ Kidney stones◦ Migraine headaches◦ Mediterranean descent
Personal History◦ Travel history◦ Congenital or acquired immunodeficiencies◦ Intra-abdominal surgeries◦ Dietary history◦ Medications◦ Sexual activity◦ Menses
Case A 9-year-old girl is brought to your office with a 6-month history of peri-umbilical pain. Characteristics of pain are described as follows: it occurs mainly after eating, lasts from 10 minutes to one hour, frequency varies since there might be times when she complains of pain twice a day but there are other times when she is symptom free for a month. She described the pain as if someone was “punching” her belly. Her symptoms worsen at school but acknowledge she eats a lot of junk food. There is no history of nocturnal pain but halitosis has been noticed. Her weight, appetite and energy level have been stable. Further history revealed BMs every 3 days and stools are hard and some intermittent soiling. Mild headaches have been associated. Her family history revealed migraines and irritable bowel syndrome on the mother.
There were no abnormalities on exam; anthropometrics plotted her on the 25th percentile.

Physical Exam OSCE Station Vitals are vital
Growth parameters: weight, height, growth velocity
Inspection◦ General Appearance and level of comfort or discomfort
Abdominal Exam◦ Auscultate◦ Percuss Palpation (to assess enlarged organs or masses)◦ Carnett sign (differentiate visceral from abdominal wall pain
DRE ◦ Impacted stool, perinanal fistuals or deep fissures
±Pelvic Exam if history suggests
Red Flags
Adapted from Uptodate
Red Flags
Differential Diagnosis Ask yourself is this ORGANIC or FUNCTIONAL?◦ Think about information
gathered from history and physical
