Assessment of Abdomen

1. Assessment of Abdomen

2. Large cavity extending from diaphragm to pelvis Vertebral column & paravertebral muscles along the back Lower rib cage & abdominal muscles in front 4 layers of large flat muscles joined midline by linea alba

3. Viscera

4. Abdominal Organs Liver fills most of RUQ, extends over to left midclavicular line. Lower edge may normally be palpable. Stomach lies below diaphragm between liver & spleen. Gallbladder lies under posterior surface of liver, just lateral to midclavicular line.

5. Small intestine lies in all 4 quads; from stomach’s pyloric valve to RLQ where it joins the colon Spleen lies obliquely under the diaphragm. Lymphatic tissue that runs parallel to 10th rib. Width extends from 9th to 11th rib. Not palpable normally.

6. Aorta lies just left of midline in upper part of abdomen, descending behind the peritoneum. 2cm below umbilicus, it bifurcates into right & left iliac arteries. Can easily palpate aortic pulsations in upper anterior abdominal wall. Right & left iliac arteries become femoral arteries in the groin area. Pulsations easily palpated ½ way between anterior superior iliac spine & symphysis pubis.

7. Abdominal Vascular Sounds

8. Pancreas is a soft lobular gland behind the stomach; lies obliquely across the posterior abdominal wall. Kidneys are bean shaped organs that are posterior to abdominal contents; protected by posterior ribs & musculature.

9. Costovertebral Angle

10. Abdominal Quadrants

11. History Appetite changes Weight changes, over what period of time Dysphagia Food intolerances Abdominal pain N/V Bowel history meds

12. Assessment of Breast

13. Lie anterior to pectoralis major & serratus anterior muscles between 2nd & 6th ribs; extend from side of sternum to midaxillary line. Tail of Spence projects up & laterally into the nipple Nipple is rough, round, & usually protrudes outward. Surface is wrinkled with milk duct openings.

14. Areola surrounds the nipple for 1-2cm radius. Montgomery’s glands are small elevated sebaceous glands on the areola that secrete a protective lipid material during lactation Areola & nipple have a darker pigmentation than the rest of the breast.

15. Glandular tissue 15-20 lobes radiate from the nipple, made up of lobules. In each lobule are clusters of alveoli that produce milk Lobules drain into lactiferous ducts then drain milk to the lactiferous sinus (storage reservoirs behind the nipple)

16. Suspensory ligaments Also called Coopers ligaments Fibrous bands that extend vertically & attach to chest wall muscles Give support to breast tissue

17. Adipose tissue Layers of subcutaneous fat that provides the bulk of the breast Proportion of these 3 varies depending on age, cycle, pregnancy, lactation & nutritional state.

18. Map out on the breast using 4 quadrants. Vertical & horizontal lines that intersect at the nipple. UOQ contains the Tail of Spence – projects into axilla, close to pectoral group of axillary lymph nodes.

19. Breast Lymphatics Central axillary lymph nodes – high up in middle of axilla Pectoral – along the lateral edge of the pectoralis major (just inside the anterior axillary fold) Subscapular – along the lateral edge of the scapula (deep in posterior axillary fold) Lateral – along the humerus (inside the upper arm)

20. Male Breast Rudimentary structure consisting of a thin disc of undeveloped tissue underlying the nipple Gynecomastia- enlarged male breast tissue, usually temporary & unilateral. Occurs during adolescence & with aging Distinguish between soft fatty enlargement of obesity and firm disc of glandular enlargement (gynecomastia)

21. Supernumerary Nipple During embryonic life, milk lines curve from the axilla to the groin bilaterally. The rest of the ridge usually atrophies. Occasionally a supernumerary nipple persists along the track of the mammary ridge.

22. Breast Self Examination No longer ROUTINELY recommended to Canadian women. Available evidence supports that BSE does not decrease mortality associated with breast cancer & carries the risk of potentially increasing benign biopsy rates. BUT, if after being informed of risks & benefits of BSE, a woman makes an informed decision to perform BSE, then she should be taught to perform this self assessment screening technique proficiently

23. Routine Breast Health Screening Women aged 40-69 have CBE by a trained HCP at least once every 2 years Women aged 40-69 discuss their risk of breast cancer & the risks & benefits of routine mammography screening with their HCP Women aged 50-69 have a screening mammogram every 2 years Women aged 70 & older discuss routine breast cancer screening with their HCP (Canadian Cancer Society, 2008)

24. Canadian Statistics 1 in 9 Canadian women will get breast cancer If a first degree relative with breast cancer, risk is 1 in 6 Risk of breast cancer in men is 1% or 170 cases per year Only 5 – 10% of cancers have an identifiable breast cancer gene (BRCA1 or BRCA2) Breast cancer is the 2nd major cause of death from cancer in women

25. History Pain Lump Discharge Rash Swelling Family hx of breast disease Breast surgery Self-care behaviors Axilla tenderness, lumps, rash

26. Abdominal Shape

27. Shifting Dullness

29. Fluid Wave

30. Breast Palpation – Vertical Strip

31. Breast Palpation - Spokes

32. Breast Palpation - Spiral
