sac-like outpouchings of colon mucosa; little herniation of GI wall.
: multiple diverticula that are not inflamed; asymptomatic
: inflamed diverticula that may cause potentially fatal obstruction, abscess, and hemorrhage(perforation-symptomatic, eventually fatal like perforation..
- => Pathophysiology
- Diverticula develop with loss of muscle mass/collagen with aging and deficiency in dietary fiber (higher risk if you're constantly constipated b/c pressure from colon.)
Fecal material or food particles collect, causing obstruction and inflammation
Erosion of the wall can occur, leading to microperforations
May lead to localized abscess or peritonitis w/ bigger perforation
Repeated attacks lead to the formation of scar tissue and strictures and obstruction
