GI Disorders - Diverticular Disease Flashcards
Etiology, pathophysiology, manifestations, diagnosis, and treatment
Diverticular Disease
Multiple diverticular (bowel protrusions) d/t increase intraluminal pressure pushing on the weak points.
Prevalence? Percentage?Why?
Occurs in 80% of 85 year olds d/t degenerative changes
Where does it occur majority of the time? Why?
- Large intestines but mostly in sigmoid colon ( S shaped)
- Stool is more formed .
Outpouching?
Extension in the wall of the gut.
Singular? Plural? Adjective?
Diverticulum = singular Diverticula = plural Diverticular = adj.
What are polyps?
abnormal tissue growth in the lumen that bulges and pushes outwards
What are required for Diverticulum to happen?
- increased intra-luminal pressure
2. weakened bowel walls (occurs w/ age)
Etiology/Risks?
Aging - d/t degenerative change
Low fibre - fiber facilitate bowel motion
Constipation - causes an increase in pressure in gut
Inactivity/poor lifestyle - activity increases peristalsis –> decrease transit time (time it takes for content to move in gut) –> less water absorbed in gut –> more watery stool
Pathophysiology
- vessel entry points on bowel wall causes weak spots
- hx of bowel sx leads to formation of scar tissues
if intraluminal pressure increases, then mucosa can herniate and push thru the muscularis externa and form diverticula
What does herniates mean?
push thru
When does outpouchings occur?
diverticula occurs
What is Diverticulosis?
Formation and appearance of diverticula
Characteristics of Diverticulosis:
- non-inflamed
- little risk of obstruction in the bowel
- usually asymptomatic
What is Diverticulitis?
Inflammation of diverticula
Characteristics of Diverticulitis:
- inflamed
- risk for perforation/rupture of the diverticula and releasing waste and intestinal bacteria into the body cavity
- risk for further complications
