In children <4 years-need 1 month of symptoms
- <=2 BM/week d
- o ≥ 1 episode incontinence/wk (after toilet trained)

- History of large-diameter stools that may obstruct the toilet
Name 10 Alarm Signs and
Symptoms That Suggest the Presence of an
Underlying Disease Causing the Constipation?
Constipation starting extremely early in life (<1 mo) Passage of meconium >48 h Family history of HD Ribbon stools Blood in the stools in the absence of anal fissures Failure to thrive Fever Bilious vomiting Abnormal thyroid gland Severe abdominal distension Perianal fistula Abnormal position of anus Absent anal or cremasteric reflex Decreased lower extremity strength/tone/reflex Tuft of hair on spine Sacral dimple Gluteal cleft deviation Extreme fear during anal inspection Anal scars Weight loss Urinary retention
What are the components of constipation management?
Education
Behavioural modification
Disimpaction
Daily maintenance stool softeners (should continue until after toilet trained to eliminate fear of defecation)
Dietary modification
What are 2 time periods where children are prone to functional constipation?
At the time of toilet learning (age 2-4 years)
During the start of school
What is fecal impaction?
Presence of a large and hard mass in the abdomen
Dilated vault filled with stool on rectal examination
History of overflow incontinence
Name 3 methods of fecal disimpaction
PEG 3350 1-1.5g/kg/day x 3 days
Enema x 6 days
High dose mineral oil
PEG via NG tube until clear effluent
What dose of PEG 3350 do you use for maintenance therapy?
Starting dose at 0.4 g/kg/day – 1 g/kg/day
For infants-dose up to 0.8 g/kg/day
Increasing the dose every two days until the child has1-2 soft stools per day
What are behavioural modifications that can be recommended in constipation?
- Routine scheduled toilet sitting for 3 min to 10 min 1-2x a day
- Ensure that the child has a footstool on which they can support their legs to effectively increase intra-abdominal pressure (valsalva)
- There should be no punishment for not stooling during the toileting time
- Praise and reward for stooling and the behaviour of toilet sitting can be offered.
- Regular physical activity
- Stool diaries
What are recommendations for dietary modifications in constipation?
- A balanced diet that includes whole grains, fruits and vegetables
- Carbohydrates (especially sorbitol) found in prune, pear and apple juices
- Fibre intake of 0.5 g/kg/day (to a maximum of 35 g/day) for all children
- For infants: reduce cow’s milk intake, increase fluid intake
How long should patients with constipation be treated for?
6 months
Until stools soft
Until after toilet training done
What stool softener is contraindicated in infancy?
Mineral oil is contraindicated in infants because of uncoordinated swallowing and the risk of aspiration and subsequent pneumonitis.
