Neurologic disorder impairing sphincter function
-
Having the patient strain during the rectal exam is useful for diagnosing patients with what?
Dyssynergic defication, rectal prolapse
-
How do you do a physical examination for a rectocele?
Have female patient strain with the examining finger oriented anteriorly
-
In a patient with constipation you can do a barium X ray to identify what 4 disorders
obstruction, megarectum, megacolon, hirshsprungs disease
-
Atonic Colon
loss of normal colonic relfexes and sensation
-
Adynamic colon
colon that is dialated and the patient is unable to move through the colon, thus they are dependent on more and more laxitives for defecation
-
Dyssynergistic defication
- in coordination of contraction of colonic and rectal muscles and internal and external sphincters
- leads to attempts to defecate against closed anal sphincters
- with or without difficulty deficating strain even with soft stools
- on examination they are inable to voluntarily relax the external sphincters on request
-
Megacolon
- Lifelong constipation
- occasional passage of an enormous formed stool
- causes are congenital (hirschsprung disease) or aquired defects in the intrinsic innervation of the colon
-

- fiber fluids fun
- D/C or change offending meds if possible
- bowel retraining
- educations and reassurance
-
What must you give with fiber/bulk laxitives?
WATER
-
How do surfactants work?
Lower stool surface tension and soften so that more water enters more easily not as good as laxatives
-
What are osmotic agents?
- Non-absorbable agents to promote fluid shift
- intestinal water secretion increases
- increases stool frequency
-
Name some osmotic agents
PEG, Lactulose, Saline
-
How do stimulant laxatives work?
Alter electrolyte transit at mucosa and increase motor activity
-
What is a fecal impaction?
- Large mass of bulky dry hard stool in the rectum secondary to chronic constipation
- watery stool may form higher in the bowel and leak around the impaction causing soiling or diarrhea
-
What are some complications of fecal impaction

- rectal tears
- rectal tissue necrosis
-
What are some symptoms of fecal impaction?
- Urge to deficate without ability to have a BM
- abdominal pain
- bloated or hard abdomen
- anorexia
- nausea and vomiting
- rectal discomfort
- generally ill feeling
- confusion
- leakage of wet stool or thin/pencil stool
-
What is a contraindication to manual disimpaction, suppositories and enemas for fecal impation?
Patients who are myelosuppressed or have altered bleeding times
-
What are some motility tests that can be done for a patient with chronic constipation
- anorectal manometry
- defecography
- pelvic floor electromyography
- anal endosonography
-

Anal fissure
-
Hematochezia
blood on toilet paper or stool
-

dont prolapse
-
second degree hemorrhoids
prolapse through anus on straining but spontaneous reduction
-
Third degree hemorrhoids
