Colonoscopy is frequently done in elderlies with complaints of abdominal pain, constipation, alteration in bowel habits and bleeding in stool essentially to rule out Colonic Cancer.
Quite often, there is no cancer but there is Colonic Diverticulosis.
Diverticulum is basically an outpouching of the weakened intestinal wall.Looking from the outside of the intestine such As during surgery, the Diverticulum will appear like an outpouching or lump on the surface.But looking from the inside surface of the bowel at colonoscopy,the Diverticulum(plural.=Diverticulae) appear like holes/discrete depressions on the inner surface of the bowel (see pics. below).
Diverticulosis can occur anywhere in the hollow intestinal tract,but frequently occur in the colon.
Colonic Diverticulosis are usually part of the ageing, chronic degenerating process.
Small bowel Diverticulosis tend to occur in younger people and they are related to congenital weakness of the bowel walls.
Uncomplicated Bowel Diverticulosis are usually asymptomatic, but complicated ones may present with symptoms much like bowel cancer.
Diverticulosis can be complicated by Infection(Diverticulitis) due to the impacted faecal matter in the Diverticulum(as seen by the yellow stuff sticking to the diverticulum in the picture above)
