What are diverticula?

(Diverticulosis are multiple diverticula...diverticulitis is the inflammation of one or more diverticula)
congenital or acquired pouchlike herniations of mucosa through the muscular wall of small intestine or colon
Where can diverticula occur?
in any part of small or large intestine, but occur mostly in SIGMOID COLON
Define etiology?
cause of disease
Define pathophysiology?
the study of how normal physiological processes are altered by disease
Describe the pathophysiology of the formation of diverticula?

it becomes herniated...so where do diverticula seem to occur?

ha! as part of the aging process
the musculature of the colon hypertrophies, then thickens, then becomes rigid...and then what happens to the mucosa and submucosa of the colon wall?

hmmm...at points of weakness in the intestinal wall, often at areas where blood vessels interrupt muscular continuity....and how does muscle weakness develop, you in the back?
All by themselves, diverticula cause few problems. However, if _____ or ______ become trapped in a diverticulum, however, blood supply to that area _______ and bacteria invades the diverticulum. And so how does diverticulis result from there?

PERITONITIS!

bacteria

diminishes

the diverticulum perforates and a local abscess forms....and so what can form if the perforated diverticulum progresses to intra-abdominal perforation?

localized inflammation in areas of ________ ______ tissue?

diverticulum
Hemorrhage can result when a ______ _____ is eroded within a diverticulum

fistulas to other organs, such as bladder and vagina.
inflammation...and so inflammation can also result in ______?
What has been implicated in the development of diverticula?
diets with small amounts of fiber because they cause less bulky stool and possible constipation
What must happen for diverticulosis and diverticulitis to occur?
there must be an increase in intraluminal pressure and muscle contractions to move fecal material through the colon
What is the etiologic factor in diverticulitis?
retained undigested food in diverticula, which compromises blood supply to that area and facilitates bacterial invasion of the sac
