Approach to pt with abd pain - GI Exam Flashcards
Acute Abdomen
medical jargon that refers to any acute condition within the abdomen that requires immediate medical or surgical attention.
Approach to the Patient With Abdominal Pain
- Note the patient’s age, gender and past medical history, precipitating factors, location of the pain, radiation and associated symptoms.
Types of Abdominal Pain (3)
- Visceral Pain (colic pain)
- Parietal Pan
- Referred Pain
Visceral Pain (colic pain):
source is usually hollow organ caused by distension or stretching. Comes and goes, crescendo/decrescendo pattern. Cramping not well localized.
Parietal Pain
Caused by inflammation of the peritoneum. Steady aching pain that is usually well localized.
Referred Pain
From a distant sight
Gall badder pain referred to?
right shoulder
Spleen pain referred to?
Left shoulder
Pancreas or aorta pain referred to?
back
_____of the pain is one of the best determinants of the diagnosis.
location
Melena
= Black tarry stools
- 50-60 ml of blood in the stomach can produce melena
- Above the “Ligament of Treitz” (very general rule)
Hematochezia
- Blood unchanged by passage through the gut usually at the level of the colon or lower
- Blood in the bowel is a cathartic
Blood mixed with stool suggests _____, blood outside the stool suggests_____.
upper colon…… sigmoid or rectum
Jaundice
Staining of tissue and body fluids with bilirubin
Jaundice - Signs and Symptoms (5)
- Yellow skin
- Scleral yellowing
- Pruritus = generalized itching all over
- Urine color – darken urine from conjugated
- Acholic feces – malodorous, gray to light colored stools
Unconjugated hyperbilirubinemia
Unconjugated bilirubin being produced at a rate exceeding the maximal rate of liver conjugation and excretion or decreased conjugation.
Unconjugated hyperbilirubinemia Etiologies (6)
- Hemolysis
- Red cell defects – sickle cell
- Ineffective erythropoiesis
- Deficient hepatic uptake
- Deficient hepatic conjugation – - hepatitis
Conjugated Hyperbilirubinemia
Impaired excretion of conjugated bilirubin from hepatocytes in the bile canaliculi or obstruction of biliary flow.
In Conjugated Hyperbilirubinemia Serum alkaline phosphatase is…..
elevated out of proportion to the transaminases
Conjugated Hyperbilirubinemia Etiologies (2)
- Intrahepatic cholestasis – hepatocellular disease, drugs, sepsis, primary biliary cirrhosis
- Extrahepatic obstruction – gallstones, biliary carcinoma, sclerosing cholangitis, parasites, pancreatic cancer, pancreatitis
Ascites
An increase accumulation of peritoneal fluid by any one or more of several mechanisms:
- Transudation of fluid from portal hypertension
- Lymphatic obstruction
- Decreased plasma oncotic pressure
- Peritoneal inflammation – peritonitis
Ascites 4 signs of free Fluid
- Bulging flanks
- Tympany at the top of the abdomen
- Fluid wave
- Shifting dullness
Ascites Most Common Differentials (3)
- Cirrhosis (80-85%)
- Malignancy (10%)
- Congestive heart failure (3%)
Fluid wave
Place patient’s or assistant’s hand in midline. Tap on one flank and palpate with the other hand. An easily palpable impulse suggests ascites.
Shifting dullness
percuss the patient on their
back and then their side. Note where the sound
changes from tympany to dull and the shift of the
sound when the patient is turned to the side.
The physical examination of the abdomen and rectum includes: (6)
- Inspection
- Auscultation
- Percussion
- Palpation
- Rectal examination
- Special techniques
Adequate exposure of the abdomen =
Xiphoid to the pubis
Inspection of the Abdomen (5)
- Must adequately expose the abdomen
- Skin - scars, striae, superficial veins
- Umbilicus – hernia, “Caput medusa”
- Contour – flat, scaphoid, protuberant
- Pulsations or peristalsis
Auscultation of the Abdomen
- Listen for bowel sounds before palpation and percussion.
- All 4 quadrants
- RLQ – best place to listen - Listen for bruits in the
midline between the
xiphoid and umbilicus.
Femoral arteries B/L.
Normal bowel sounds =
high pitched “tinkle” about every 3-5 seconds.
Absent Bowel Sounds =
No bowel sounds after 2 minutes
Borborygmi
- Increased, hyperactive bowel sounds,
- Low pitched rumbling
- Hyperperistalsis
Abdominal bruits
A soft sound made by disrupted arterial flow through a narrowed artery. causes a “hissing sound”
Location of aortic bruits
between the umbilicus and xiphoid
Location of Renal artery bruits
just lateral to the aorta
Location of Femoral Artery Bruits
along the inguinal ligament
