Small intestine
pyloric sphincter to ileocecal junction
three regions
duodenum
jejunum
ileum
Function - chemical digestion and absorption
microvilli, villi and circular folds increase surface area
4. Small bowel surgery
5. Small intestine
6. Review of Anatomy and Physiology Large intestine - colon
ileocecal valve to anus
Cecum - first part of intestine - appendix
Colon divided into 3 parts

8. Large Intestine
9. Assessment of Bowel Function Subjective

associated symptoms
10. Sample Interview Questions Can you describe the type of cramping and abdominal pain you are having?
Have you every had bleeding from your rectum?
Have you noticed any changes in your bowel habits?
11. Assessing the Abdomen Inspection, auscultation, percussion and palpation as described
Rectal exam - polyps
Stool for occult blood
+ requires further testing for colon CA or GI bleeding 2nd to peptic ulcers, ulcerative colitis or diverticulosis
12. Blood and Stool Melena - black tarry stool
Blood on Stool - bleeding sigmoid colon, rectum
Blood in Stool - colon, ulcerative colitis,
diverticulitis, tumor, ulcer
Stool black, hard = oral iron

28. Appendicitis
Clinical Manifestations
continuous mild generalized upper abd pain
then intensifies and localizes to RLQ
rebound tenderness - tenderness on release of pressure at McBurney’s point
+ Rt heel tap pain
What about pain medications?
nausea, anorexia, vomiting, low-grade fever
perforation - increased pain, temp, abscess
29. Appendicitis Pathophysiology The appendix can become obstructed by fecalith (hard masses of feces) a stone, inflammation or parasites.
As a result of the obstruction the appendix becomes distended with fluid.
This increases pressure within the appendix and impairs its blood supply.
The lack of blood supply leads to inflammation, edema, ulceration, and infection of the tissue.
Can become necrotic and perforate if treatment is not indicated.
