Abdominal Examination H.A.Soleimani MD Gastroenterologist Adapted by Judy Gearhart, MD Gastrointestinal History www.rightdiagnosis.com Be a detective! Think about what all could cause this presentation. What are risk factors? How to perform the physical examination? Exposing only the area that are being examined Offer a chaperone for both sexes. Explain what you're going to do Sequential Important aspects of physical examination The examiner should continue speaking to the patient Showing care to his disease and answer to patient’s questions Gloves should be worn when.. Examining any individual with exudative lesions or weeping dermatitis When handling blood-soiled or body fluid-soiled sheets or clothing General principles of exam Have the patient empty their bladder before examination Have the patient lie in a comfortable, flat, supine position Have them keep their arms at their sides or folded on the chest General principles of exam Before the exam, ask the patient to identify painful areas so that you can examine those areas last During the exam pay attention to their facial expression to assess for sign of discomfort General principles of exam Use warm hand, warm stethoscope, and have short finger nails Approach the patient slowly and deliberately explaining what you will be doing General principles of exam Stand right side of the bed (tradition-depends on patient, room, and situation) Exam with right hand (again, it depends) Head just a little elevated Ask the patient to keep the mouth partially open and breathe gently General principles of exam If muscles remain tense, patient may be asked to rest feet on table with hips and knees flexed Other helpful points on examination Take a spare bed sheet and drape it over their lower body such that it just covers the upper edge of their underwear General principles of exam If the patient is ticklish or frightened, initially use the patient’s hand under yours as you palpate When patient calms then use your hands to palpate. Watch the patient’s face for discomfort. Think Anatomically When looking, listening, feeling and percussing, imagine what organs live in the area that you are examining. Right Upper Quadrant (RUQ) liver, gallbladder, duodenum, right kidney and hepatic flexure of colon Right Lower Quadrant (RLQ) Cecum, appendix (in case of female, right ovary & tube) Left Lower Quadrant (LLQ) Sigmoid colon (in case of female, left ovary & tube) Left Upper Quadrant (LUQ) Stomach, spleen, left kidney, pancreas (tail), splenic flexure of colon Epigastric Area Stomach, pancreas (head and body), aorta Landmarks of the abdominal wall, Costal margin, umbilicus, iliac crest, anterior superior iliac spine, symphysis pubis, pubic tubercle, inguinal ligament, rectus abdominis muscle, xiphoid process. Physical Examination of the Abdomen Inspection Auscultation Percussion Palpation Special Tests Appearance of the abdomen Is Aortic pulsation? Is it flat or Scaphoid (Normally)? Distended? If enlarged, does this appear symmetric? With bulging or moving? Appearance of the abdomen Global abdominal enlargement is usually caused by air, fluid, or fat. Appearance of the abdomen Localized enlargement, probably distended GB space occupying lesion, hepatomegaly…. An aortic aneurysm Palpable mass Patient feeling of pulsation On rare occasions, a lump can be visible. Appearance of the abdomen (Skin) Abnormal venous patterns Abnormal discoloration Umbilicus is sunken Striae Stretch marks are a light silver hue. Pregnant and obese individuals Cushing’s syndrome (more purple or pink). Appearance of the abdomen (Skin) Tattoos Scars Cullen’s sign Ecchymosis, periumbilical. (intraperitoneal hemorrhage ruptured ectopic pregnancy, hemorrhagic pancreatitis..) Grey-Turner’s sign Ecchymosis of flanks. (retroperitoneal hemorrhage such as hemorrhagic pancreatitis) Upward flow direction indicates IVC obstruction Outward flow pattern from umbilicus in all directions ? Portal HTN Appearance of the abdomen Areas which become more pronounced when the patient valsalvas are often associated with ventral hernias Visible Pulsations More conspicuous in the thin than in the fat Greater in the old than in the young. Increased in thyrotoxicosis, hypertension, or aortic regurgitation) In those with an aortic aneurysm and tortuous aorta In those who have a mass joining the aorta to the anterior abdominal wall. Visible gastric Peristalsis Visible intestinal Peristalsis Gastric peristalsis is commonly seen in neonates with congenital hypertrophic pyloric stenosis Intestinal peristalsis in partial and chronic intestinal obstruction Colonic obstruction is usually not manifest as visible peristalsis Appearance of the abdomen Patient's movement Patients with kidney stones will frequently writhe on the examination table, unable to find a comfortable position Appearance of the abdomen Patient's movement Patients with peritonitis prefer to lie very still as any motion causes further peritoneal irritation and pain. Auscultation Abdominal examination Auscultation for bowel sounds It is performed before percussion or palpation Auscultation for bowel sounds Normal sounds are due to peristaltic activity. Peristalsis: A pregressive wavelike movement that occurs involuntarily in hollow tubes of the body. Auscultation Listening for 15-60 seconds Bowel sounds cannot be said to be absent unless they are not heard after listening for 3-5 minutes. Three things about bowel sound Are bowel sounds present? If present, are they frequent or sparse (i.e.quantity)? What is the nature of the sounds (i.e.quality)? Bowel sound decrease Inflammatory processes of the serosa After abdominal surgery In response to narcotic analgesics or anesthesia. Bowel Sounds Increase Inflammation of the intestinal mucosa will cause hyperactive bowel sounds. Auscultation for bowel sounds Processes which lead to intestinal obstruction initially cause frequent bowel sounds, referred to as "rushes." Auscultation for bowel sounds “Rushes" means as the intestines trying to force their contents through a tight opening. Auscultation for bowel sounds “Rushes" is followed by decreased sound, called "tinkles," and then silence. Bruits Bruits confined to systole do not necessarily indicate disease. Auscultation for vascular sounds (bruits) Aortic (midline between umbilicus and xiphoid Renal (two inches superior to and two inches lateral to umbilicus) Common iliac (midway between umbilicus and midpoint of inguinal ligament) Auscultation for vascular sounds (bruits) Presence of a bruit on the renal artery would lend supporting evidence for the existence of renal artery stenosis. Percussion Abdominal examination Percussion Sounds Resonance (heard over lung tissue) Tympany (heard over most of abdomen) Dullness (heard over solid organs) Flatness (heard over muscle) Percussion (technique) DIP joint of third finger (pleximeter) pressed firmly on the abdomen remainder of hand not touching the abdomen Same technique as for lungs Percussion (technique) Striking hand should move only at the wrist, with only little more than force of gravity Percussion (technique) Middle finger of striking hand (plexor) should knock the pleximeter firmly, with a strong note There are two basic sounds with Percussion Tympanitic (drum-like) sounds produced by percussing over air filled structures. There are two basic sounds with Percussion Dull sounds that occur when a solid structure (e.g. liver) or fluid (e.g. ascites) lies beneath the region being examined. Examination of Liver (Percussion) Midclavicular line is noted Second intercostal space is noted Two solid organs are percussable in the normal patient Liver: Covered by the ribs. Edge may protrude 1-2 centimeter below the costal margin. Spleen: smaller and protected by the ribs. To determine the size of the liver Percuss hepatic dullness from above (lung) and below (bowel). Normal liver span = 6 to 12 cm in the midclavicular line. To determine the size of the liver Start just below the right breast in a line with the middle of the clavicle. Percussion here should produce a resonant note. To determine the size of the liver As you move your hand down you will percuss over the liver, which will produce a duller sound. To determine the size of the liver Continue downward until the sound changes once again. This is the inferior margin of the liver. Examination of Liver (Percussion) Upper margin is noted by first dull percussion note Lower margin is noted by first tympanitic note Examination of Spleen (Percussion) Percussion at Castell’s Spot Castell’s Spot identified Left anterior axillary line identified Left lower costal margin identified Percussion at Castell’s Spot while patient inhales and exhales deeply Dull tone indicates possible splenomegaly Spleen percussion Enlarged spleen: produces a dull tone, in the LUQ Palpation Abdominal examination Abdominal Palpation Technique Light Deep Liver edge Spleen tip Kidneys Aorta Masses Abdominal palpation To palpate four quadrants superficially from LLQ counterclockwise Light Palpation Light Palpation First warm your hands by rubbing them together before placing them on the patient. Abdominal wall depressed approximately 1 cm Palpation (light) Any areas of pain or tenderness are reserved for evaluation at the end of the exam Palpation Light palpation assesses Tenderness (muscle splinting, wide eyes, moaning, teeth gritting). Muscle tone, Cutaneous hypersensitivity (suggests peritoneal irritation) Palpation Light palpation assesses Superficial mass (intramural): more prominent with head raised Intra-abdominal mass: less prominent with head raised Deep Palpation Deep Palpation Use palmar surface of fingers Deep, firm, gentle maneuver Use finger pads (do not “dig in” with finger tips) Deep Palpation Palpate tender areas last Try to identify abdominal masses or areas of deep tenderness Two handed technique When deep palpation is difficult, examiner may want to use left hand placed over right hand to help exert pressure Normal structures that may be palpable Sigmoid colon Liver Kidney Abdominal aorta Iliac artery Distended bladder Gravid and nongravid uterus Xyphoid process spleen Abdominal mass Intra abdominal masses or enlarged liver, gallbladder or spleen Abdominal wall mass Intra abdominal masses or enlargements of the liver, gallbladder or spleen will shift down with inspiration and back with expiration. (not true of masses within the abdominal wall or retroperitoneal structures). Abdominal pain and Tenderness: Visceral Somatic Visceral pain Pain from an organic lesion or functional disturbance within an abdominal viscus (dull, poorly localized, and difficult for the patient to characterize). Somatic pain Painful lesion of the skin Sharp, bright, and well localized Indicates involvement of parietal peritoneum or the abdominal wall itself Abdominal muscle spasm Voluntary guarding Tensing abdominal muscles due to patient anxiety, ticklishness, or toprevent palpation to a painful area Involuntary guarding Muscular spasm or rigidity due to peritoneal inflammation May be localized (early appendicitis )or diffuse (perforated bowel) Board-like rigidity Abdominal wall is tense, even as rigid as a board. Caused by the spasm of abdominal muscle due to peritoneal irritation. Palpation of Liver, Spleen, and Aorta Liver palpation (Standard Method) Start in the RUQ,10 centimeters below the rib margin in the midclavicular line Place left hand posteriorly parallel to and supporting 11th & 12th ribs on right. Standard Method Liver palpation Ask the patient to take a deep breath. You may feel the edge of the liver press against your fingers. Liver palpation (Standard Method) Palpating hand is held steady while patient inhales Liver palpation (Standard Method) Palpating hand is lifted and moved while the patient breathes out Alternate Method Liver palpation Stand by the patient's chest. "Hook" your fingers just below the costal margin and press firmly. Hepatojugular reflux sign If you press the liver, you will find the dilated jugular vein becomes more bulged or distended, as from the enlargement of liver passive congestion resulted from right failure. Spleen palpation Support lower left rib cage with left hand while patient is supine and lift anteriorly on the rib cage. Spleen palpation Palpate upwards toward spleen with finger tips of right hand, starting below left costal margin. Have the patient take a deep breath. Seldom palpable in normal adults. Palpation of Aorta Press down deeply in the midline above the umbilicus with flat palm. The aortic pulsation is easily felt on most individuals. Examination of Aorta Hands then oriented vertically on either side of midline with distal fingers at level of pulsation; equal pressure applied until pulsation is palpated A well defined, pulsatile mass, greater than cm across, suggests an aortic aneurysm. Special exam Murphy’s Sign McBurney’s Point Rovsing’s Sign Psoas Sign Obturator Sign Re bound Tenderness Costovertebral tenderness Shifting Dullness Fluid wave Murphy’s Sign (acute cholecystitis) Examiner’s hand is at middle inferior border of liver. Patient is asked to take deep inspiration. If positive patient will experience pain and will stop short of full inspiration Hepatitis, subdiaphragmatic abscess Cholecystitis McBurney’s Point Localized tenderness Just below midpoint of line between right anterior iliac crest and umbilicus. Heel strike, riding over bumps in road while driving, coughing, will produce pain. McBurney’s Point (Common Causes) Appendicitis Incarcerated or strangulated hernia Ovarian torsion (twisted Fallopian tube) Pelvic inflammatory disease Abdominal abscess Hepatitis Diverticular disease Meckel''s diverticulum Rovsing’s Sign Patient will experience right lower quadrant pain (in region of McBurney’s Point) when left lower quadrant is palpated. Non-Classical Appendicitis Iliopsoas Sign Obturator Sign Iliopsoas Sign Patient lies on side, extends leg at the hip or lies on back, flexes hip against resistance of examiner’s hand on thigh. Inflamed retrocecal appendix pain Iliopsoas Sign Anatomic basis for the psoas sign: inflamed appendix is in a retroperitoneal location in contact with the psoas muscle, which is stretched by this maneuver. Obturator Sign Internally rotate right leg at the hip with the knee at 90 degrees of flexion. Will produce pain if Obturator Sign Anatomic basis for the obturator sign: inflamed appendix in the pelvis is in contact with the obturator internus muscle, which is stretched by this maneuver. Rebound Tenderness (For peritoneal irritation) Warn the patient what you are about to do. Press deeply on the abdomen with your hand. After a moment, quickly release pressure. If it hurts more when you release, the patient has rebound tenderness. [4] Costovertebral Tenderness (Often with renal disease) Use the heel of your closed fist to strike the patient firmly over the costovertebral angles. Compare the left and right sides. Examination for Shifting Dullness Patient rolled slightly toward the examined side; movement of the dull point medially is described as “shifting dullness” and suggests ascites Fluid wave
