Abdominal Exam Inspection Auscultation Percussion Palpate
percussion includes percussion of liver span, light and deep palpation, palpation of liver edge, spleen tip, kidneys, and aorta. The abdominal examination consists of inspection, auscultation, percussion including percussion of liver span, light and deep palpation, palpation of liver edge, spleen tip, kidneys, and aorta. The abdominal exam is done with the patient supine at 90o Order of exam is critical. Auscultate BEFORE palpating!

Physical Examination General Appearance and Vitals (sick vs Not sick)
Abdominal exam -Inspection (scars, masses, ecchymosis, distention) -Auscultation (bowel sounds, bruits), -Percussion (organomegaly, dullness) -Palpation (tenderness, guarding, rebound, referred pain, masses) -Don't forget GU, Rectal and Pelvic examination

Empty bladder Patient comfort (pillows and draping) Arms at side or crossed over chest Ask the patient to point to any painful areas; examine last Warm hands and stethoscope Ticklish or nervous patients: slow movements, distraction, use their hands

Examine the patients hand

Hernia sites Ask the patient to stand up and turn his face to one side and cough, if there is an impulse on coughing suggests presence of an. hernia

Ascites Prominent veins (caput medusae)

ABDOMEN: Inspection There should be adequate exposure of the abdomen for proper inspection. The patient should be exposed from the inferior chest to the anterior iliac spines bilaterally. ABDOMEN: Inspection There should be adequate exposure of the abdomen for proper inspection. The patient should be exposed from the inferior chest to the anterior iliac spines bilaterally.

ABDOMINAL EXAMINATION AUSCULTATION
Place the diaphragm of the stethoscope to the right of the umbilicus Bowel sounds (borborygmi) are caused by peristaltic movements Occur every 5-10 sec. Absence of b.s.: paralytic ileus or peritonitis Bruits over aorta and renal a. could be a sign of an aneurysm and stenosis

Percussion Percussion Percussion: the left and right abdomen should be percussed above and below the umbilicus. Most examiners will percuss 8 or more areas. Note: This percussion is performed as a screening maneuver. Later, the liver Percussion: the left and right abdomen should be percussed above and below the umbilicus. Most examiners will percuss 8 or more areas.

ABDOMINAL EXAMINATION FLUID THRILL
Place the palm of your left hand against the left side of the abdomen Flick a finger against the right side of the abdomen Ask the patient to put the edge of a hand on the midline of the abdomen If a ripple is felt upon flicking we call it a fluid thrill = ascites IF IT IS NOT CLEAR

Percussion: Liver span
The liver span is estimated by percussion. Remember that it is easier to hear the change from resonance to dullness – so proceed with percussion from areas of resonance to areas of dullness. Upper border: In the midclavicular line start percussing in the chest moving down towards the abdomen about ½ to 1 cm at a time. Note where the percussion notes change from resonate to dull. Lower border: In the midclavicular line begin percussion below the unbillicus and proceed upward until dullness is encounter. 127: Percussion: Liver span The liver span is estimated by percussion. Remember that it is easier to hear the change from resonance to dullness – so proceed with percussion from areas of resonance to areas of dullness. Upper border: In the midclavicular line start percussing in the chest moving down towards the abdomen about ½ to 1 cm at a time. Note where the percussion notes change from resonate to dull. Lower border: In the midclavicular line begin percussion below the unbillicus and proceed upward until dullness is encounter. The distance between the two areas where dullness is first encountered is the liver span. Liver span is normally 6 to 12 cm in the midclavicular line. The distance between the two areas where dullness is first encountered is the liver span. Liver span is normally 6 to 12 cm in the midclavicular line.

Liver Span: Scratch Test
Start in the same areas above and below the liver as you would with percussion. Instead of percussing lightly, scratch moving your finger back and forth while listening over the liver. Since sound is conducted better in solids than in air, when the louder sounds are heard you are over the liver. Mark the superior and inferior boarders of the liver span in the midclavicular line Liver Span: May Do Scratch Test If you are unable to determine liver span by percussion then the scratch test may be used. Start in the same areas above and below the liver as you would with percussion. Instead of percussing lightly scratch moving your finger back and forth while listening over the liver. Since sound is conducted better in solids than in air, when the louder sounds are heard you are over the liver. Mark the superior and inferior boarders of the liver span in the midclavicular line

Percuss for shifting dullness 1

ABDOMINAL EXAMINATION PALPATION
Tenderness: discomfort and resistance to palpation Involuntary guarding: reflex contraction of the abdominal muscles Rebound tenderness: patient feels pain when the hand is released Tenderness + rigidity: perforated viscus Palpable mass (enlarged organ, faeces, tumour) Aortic pulsation ABNORMAL FINDINGS

Palpation Palpation of the abdomen should be performed in a systematic way using the 9 named segments of the abdomen: right and left hypochondrium, right and left flank, right and left iliac fossa, the umbilical area, the epigastrium and the suprapubic region. -

Abdominal Palpation Palpate lightly in all 4 quadrants. Press down around 1 cm. Remember to look at the patient’s face during palpation to see if any tenderness is elicited Palpation: Lightly, all 4 quadrants Palpate lightly in all 4 quadrants. Press down around 1 cm. Remember to look at the patient’s face during palpation to see if any tenderness is elicited.

One should use two hands. Press down around 4 cm
Palpation: Deeply, all 4 quadrants Palpation: Deeply, all 4 quadrants One should use two hands. Press down around 4 cm One should use two hands. Press down around 4 cm

Palpation: Liver Stand on the pt’s right side. Place your left hand behind the patient’s R side under the 11th and 12th rib area. Press upward with the L hand. Place your R hand on the pt’s abdomen well below where you percussed the liver edge : Palpation: Liver Stand on the pt’s right side. Place your left hand behind the patient’s R side under the 11th and 12th rib area. Press upward with the L hand. Place your R hand on the pt’s abd well below where you percussed the liver edge Ask the patient to take a deep breath and gently push your R hand inward and upward trying to feel the liver edge as it comes down during inspiration. Gradually move your R hand more superior repeating the process until you feel the liver edge or you get to the costal margin.

ABDOMINAL EXAMINATION MURPHY’S SIGN
Pain in RUQ Inflammation of gallbladder (cholecystitis) Courvoisier's law Murphy's sign sign of gallbladder disease consisting of pain on taking a deep breath when the examiner's fingers are on the approximate location of the gallbladder. Pain on inspiration during gentle palpation below the right subcostal arch. As the patient breathes in, the liver moves down exposing the gallbladder to pressure from the examiners hand. Murpy’s sign may also be present with hepatitis. The gallbladder (GB) is filled with echogenic sludge (Sl) and a gallstone (red arrow) is impacted in the gallbladder neck. The gallbladder wall (red arrowheads) is markedly thickened indicative of wall edema and there are pericholecystic fluid (blue arrows) pockets surrounding the gallbladder. Courvoisier's law states that in the presence of an enlarged gall bladder which is nontender and accompanied with jaundice, the cause is unlikely to be gallstones.

130-131: Palpation of Liver: Alternative Method
It is acceptable during palpation of the liver to use both hands to palpate abdomen. You use the fingers of one hand to palpate and the other hand is used to apply pressure to the dorsum of the other hand. Thus the hand you are using to palpate does not need to be used to apply pressure It is acceptable during palpation of the liver to use both hands to palpate abdomen. You use the fingers of one hand to palpate and the other hand is used to apply pressure to the dorsum of the other hand. Thus the hand you are using to palpate does not need to be used to apply pressure.

Cases… A 23 year old female presents with severe, intermittent right lower quadrant pain associated with nausea and vomiting. She has no medical history. Her vital signs reveal tachycardia but are otherwise normal. Physical exam shows a soft abdomen, RLQ TTP without peritoneal signs. Pelvic (which is part of the physical exam), shows scant discharge. If you could only order one test, what would it be? What is on your differential?

Abdominal pain What else do you want to know?
What is on your differential diagnosis so far? (healthy male with RLQ abd pain….) How do you approach the complaint of abdominal pain in general? Let’s review in this lecture: Types of pain History and physical examination Labs and imaging Abdominal pain in special populations (Elderly, HIV) Clinical pearls to help you in the ED

What kind of pain is it? Visceral Parietal Referred
Involves hollow or solid organs; midline pain due to bilateral innvervation Steady ache or vague discomfort to excruciating or colicky pain Poorly localized Epigastric region: stomach, duodenum, biliary tract Periumbilical: small bowel, appendix, cecum Suprapubic: colon, sigmoid, GU tract Parietal Involves parietal peritoneum Localized pain Causes tenderness and guarding which progress to rigidity and rebound as peritonitis develops Referred Produces symptoms not signs Based on developmental embryology Ureteral obstruction → testicular pain Subdiaphragmatic irritation → ipsilateral shoulder or supraclavicular pain Gynecologic pathology → back or proximal lower extremity Biliary disease → right infrascapular pain MI → epigastric, neck, jaw or upper extremity pain

Moving on to the Physical Exam
General Vital Signs Abdomen Look for distention, scars, masses Auscultate – hyperactive or obstructive BS increase likelihood of SBO fivefold – otherwise not very helpful Percuss for tympany Palpate for tenderness, masses, aortic aneurysm, organomegaly, rebound, guarding, rigidity Look for hernias! rectal exam Pelvic exam Vaginal discharge – Culture Adenexal mass or fullness Cardiac Lungs Orthostatic VS are less reliable in the diabetic, elderly, those on beta-blocker. Pulse increase of 30 or presyncope on standing are highly sensitive for loss of 1 L of blood or 3L of fluid. BP changes are less reliable. Patient must be standing at least one minute before measurements are taken.

Abdominal Findings Guarding Rebound
Voluntary Contraction of abdominal musculature in anticipation of palpation Diminish by having patient flex knees Involuntary Reflex spasm of abdominal muscles aka: rigidity Suggests peritoneal irritation Rebound Present in 1 of 4 patients without peritonitis Pain referred to the point of maximum tenderness when palpating an adjacent quadrant is suggestive of peritonitis Rovsing’s sign in appendicitis Rectal exam Little evidence that tenderness adds any useful information beyond abdominal examination Gross blood or melena indicates a GIB Heme positive stool – 10% of people over the age of 50 sent home with diagnosis of NSAP and heme positive stools were found to have cancer within a year. Heme positive stool in the setting of suspected PUD should elicit more urgent referral for further evaluation

Differential Diagnosis
Use history and physical exam to narrow it down Rule out life-threatening pathology

Abdominal Pain in the Elderly
Mortality rate for abdominal pain in the elderly is 11-14% Perception of pain is altered Altered reporting of pain: stoicism, fear, communication problems Most common causes: Cholecystitis Appendicitis Bowel obstruction Diverticulitis Perforated peptic ulcer Don’t miss these: AAA, ruptured AAA Mesenteric ischemia Myocardial ischemia Aortic dissection

Abdominal Pain in the Elderly
Appendicitis – do not exclude it because of prolonged symptoms. Only 20% will have fever, N/V, RLQ pain and ↑WBC Acute cholecystitis – most common surgical emergency in the elderly. Perforated peptic ulcer – only 50% report a sudden onset of pain. In one series, missed diagnosis of PPU was leading cause of death. Mesenteric ischemia – we make the diagnosis only 25% of the time. Early diagnosis improves chances of survival. Overall survival is 30%. Increased frequency of abdominal aortic aneurysms AAA may look like renal colic in elderly patients

Mesenteric Ischemia Consider this diagnosis in all elderly patients with risk factors Atrial fibrillation, recent MI Atherosclerosis, CHF, digoxin therapy Hypercoagulability, prior DVT, liver disease Severe pain, often refractory to analgesics Relatively normal abdominal exam Embolic source: sudden onset (more gradual if thrombosis) Nausea, vomiting and anorexia are common 50% will have diarrhea Eventually stools will be guiaic-positive Metabolic acidosis and extreme leukocytosis when advanced disease is present (bowel necrosis) Diagnosis requires mesenteric angiography or CT angiography

Abdominal Aortic Aneurysm
Risk increases with age, women >70, men >55 Abdominal pain in 70-80% (not back pain!) Back pain in 50% Sudden onset of significant pain Atypical locations of pain: hips, inguinal area, external genitalia Syncope can occur Hypotension may be present Palpation of a tender, enlarged aorta on exam is an important finding May present with hematuria Suspect it in any older patient with back, flank or abdominal pain especially with a renal colic presentation Ultrasound can reveal the presence of a AAA but is not helpful for rupture. CT abd/pelvis without contrast for stable patients. High suspicion in an unstable patient requires surgical consult and emergent surgery.
