RAD-146 PATHOLOGY OF LARGE INTESTINE

• inflammation of the small intestine
• gastroenteritis

a chronic inflammatory condition of unknown pathology involving any part of the GI tract but mostly common involving the terminal ileum

a infection of the lumen of the small intestine due to the flagellate protozoan (giardia lamblia ) spread by contaminated food or water and person to person contact

an intestinal obstruction

• this is due to the cessation of peristalsis
• causes include peritonitis appendicitis or presence of certai ndrugs

• a physical blackage of the bowel
• may be due to tumors adhesions or hernias

• a failure of the embryonic connection with the yolk sac to disappear
• as an outpouching size of a small finger of the distal ileum

inflammatory condition of the large intestine that may be cause by many factors including bacteria infection diet stress and other environemental conditions

• severe form of colitis
• leads to ulcers developing along the mucosal wall

• small outpouchings of the mucosal wall resulting from herniation of the inner wall of the colon (usually the sigmoid )
• this is a benign condition that is usually asymptomatic and is believed to be caused by a low fiber diet

the condition of having numerous diverticula

when diverticula become infected and inflamed

• "new growth" and is another word for tumour
• they are malignant or benign
• it is most common cancer of large intestine in sigmoid and rectum
• it commonly encircles the lumen of the colon and causes "apple core" or napkin ring llesions

sac like projection similar to diverticula except they project inward

a loop of bowel twisting upon itself

a teloscoping of one part of the intestine into another

a condition in which part of the intestine bulges through a weak area in muscles in the abdomen and thigh region it occurs in the groin

• occurs as a result of an absence of ganglion cells in the rectosigmoid region
• preistalsis is lacking and as a result the normal evacuation of stool is impaired and large amts of feces are retained in the sigmoid colon
