a disorder characterized by repeated stool
evacuation in inappropriate places in children over
the age of four
encopresis
primary: children who never reached continence
secondary: children who reached continence for at
least a year and are now relapsed
involuntary
sympathetic nervous
When the rectum is empty, the SNS inhibits the
system role
contraction of the rectal wall, and contracts the
internal anal sphincter (IAS) to prevent leakage
when the rectum is filled post mass transit, it stretches
and the PNS sends information to the CNS to
parasympathetic nervous coordinate bowel elimination. The rectum then
system role contracts in conjunction with the ENS and the IAS
relaxes. Feces then moves down the anal canal to the
external anal sphincter (EAS)
, The intrinsic nervous system within the bowel wall.
enteric nervous system This system responds to a variety of stimuli and
generates peristalsis
the involuntary relaxation of the IAS when the rectum
rectoanal inhibitory reflex is stretched that allows feces to move down anal
canal
when rectal contents contact Anoderm (receptors at
distal anal canal) for differentiation
sampling reflex
allows squamous epithelium below the Denate Line
with sensory receptors that differentiate between
solid, liquid, gaseous rectal contents
with cotton swab, swipe at 5 and 7 o'clock on the
buttocks with the patient in the modified lithotomy
position
anal wink
a focused physical exam that assesses prostate and
pelvic muscle control and verifies function of
pudendal nerve
in modified lithotomy position, squeeze penis glans to
verify external anal sphincter wink or flick the clitoris
in females
bulbocavernosus reflex
a focused physical exam that assesses prostate and
pelvic muscle control and verifies function of
pudendal nerve
1: colonic transit, stool volume, and consistency
2: sensory awareness
5 factors that promote
3: sphincter competence
continence
4: rectal compliance and capacity
5: extrinsic factors
The absorptive capacity of the bowel is overwhelmed
secretory diarrhea by the volume of water and electrolytes that are
secreted into it
, osmotic (absorptive) inadequate or reduced absorption of the bowel
diarrhea
functional (motility) Increased motility results in decreased contact time of
diarrhea the stool with the lumen and intestinal mucosa
composed of smooth muscle that maintains sphincter
external anal sphincter tone (contraction) and striated muscle that permits
voluntary control/contractility
parasympathetic nervous part of the autonomic nervous system that acts to
system promote colonic peristalsis and motility activity
sympathetic nervous part of the autonomic nervous system that acts to
system reduce intestinal motility and secretions
foods that contain soluble fiber have the ability to
absorb and retain water
soluble fiber
*use to help resolve diarrhea
foods that contain insoluble fiber add bulk to the
stool and do not absorb water
insoluble fiber
*use to help resolve constipation
cause is unknown but thought to be multifactorial
including: multifactorial: visceral hypersensitivity,
enhanced GI permeability known as "leaky gut",
irritable bowel syndrome altered composition of the GI microbiota, low-grade
inflammation, altered immune response, autonomic
nervous system dysfunction, altered bile acid
metabolism, and psychological distress
Abdominal pain, bloating and distention, feelings of
incomplete emptying, changes in stool frequency and
IBS s/s consistency, pain relieved by defecation, Abdominal
pain associated with eating and intraluminal
stimulation such as gas, constipation and/or diarrhea
