Comprehensive Guide to Abdominal Examination

Introduction

The abdominal exam follows a thorough history that confirms abdominal involvement. It proceeds with a systematic physical examination consisting of a general survey, inspection, palpation, percussion, and auscultation, plus special maneuvers such as hernia assessment and rectal examination.

1. General Survey & Prerequisites

• Informed consent and patient privacy are mandatory before any examination.
• Ensure the patient is comfortable, lying supine on a well‑covered table.
• Record consciousness, orientation, nutritional status (BMI), and any obvious skin lesions.

2. Inspection

• Abdominal contour:
• Scaphoid (sunken) – often seen in chronic illness or malnutrition.
• Distended – may indicate fluid, gas, pregnancy, obstruction, tumor, or a full bladder.
• Objective assessment: Place a ruler or scale across the abdomen; a flat abdomen touches the scale along its length, whereas a scaphoid abdomen touches only at the ends.
• Organ position: Normal liver tip lies midway between the right costal margin and the umbilicus. Displacement upward suggests a pelvic mass; downward displacement suggests a subphrenic process.
• Skin examination:
• Look for discoloration, scars, sinuses, or stretch marks.
• Cullen’s sign (periumbilical bruising) may indicate intra‑abdominal hemorrhage.
• Dilated veins suggest obstruction.
• Visible masses: Note size, shape, and location; describe any surface changes.
• Abdominal movements:
• Respiratory movement (normal rise/fall).
• Peristaltic waves (visible in obstruction).
• Pulsations (aortic, renal, or pathological aneurysms).
• Hernia screening: Inspect inguinal, umbilical, and incisional areas for bulges.
• Spine and back: Observe for scoliosis, kyphosis, or lumbar tenderness that may affect abdominal findings.

3. Palpation

• Patient positioning: Knees flexed, arms relaxed at the sides to reduce abdominal wall tension.
• Superficial palpation:
• Assess temperature, tenderness, and superficial masses.
• Begin away from the area of maximal pain and work toward it.
• Deep palpation:
• Use the flat of the hand, moving from the right lower quadrant upward for the liver; feel the hepatic edge on inspiration.
• For the spleen, palpate the left upper quadrant with the patient in the right lateral decubitus position.
• Kidneys are examined by placing one hand posterior to the flank and the other anterior, applying gentle pressure.
• Mass evaluation:
• Determine size, consistency, mobility, surface, and relation to surrounding structures.
• Fixation test: Ask the patient to contract abdominal muscles; a fixed mass becomes less prominent, whereas a mobile mass may become more evident.
• Special signs:
• Murphy’s sign (palpation of the gallbladder during inspiration) – not detailed in the transcript but part of standard exam.

4. Percussion

• Technique: Tap lightly over the abdomen in a systematic grid (starting at the second intercostal space, moving downwards).
• Findings:
• Tympanic sounds over gas‑filled bowel.
• Dullness over solid organs or fluid collections.
• Shifting dullness: Patient lies supine, percussion reveals dullness that shifts when the patient rolls onto the opposite side – indicates free fluid.
• Fluid wave test: Light tapping on one flank produces a wave felt on the opposite side, confirming ascites.

5. Auscultation (Oscultation)

• Bowel sounds: Use the diaphragm of the stethoscope; listen in all four quadrants for frequency and character (hyperactive, hypoactive, or absent).
• Vascular sounds:
• Listen for bruits over the aorta, renal arteries, and iliac vessels.
• Splashing sound: After the patient drinks water, ask them to shake; a splash indicates fluid in the stomach or bowel.
• Special maneuvers:
• Place the stethoscope over the epigastrium and ask the patient to cough; increased turbulence may reveal obstruction.

6. Special Examinations

• Hernia assessment: Palpate inguinal canals with the patient standing and supine; ask the patient to cough to elicit a bulge.
• Rectal examination (left lateral position):
• Inspect perianal skin for fissures, fistulas, or hemorrhoids.
• Perform a digital rectal exam to assess tone, prostate size, and any palpable masses.
• Use a proctoscope if needed for direct visualization, biopsy, or therapeutic procedures.
• Virchow’s node: Palpate the left supraclavicular fossa for a hard, enlarged node that may indicate intra‑abdominal malignancy.

7. Concluding the Examination

• Summarize findings from each step.
• Formulate a provisional diagnosis and decide on further investigations (ultrasound, CT, labs).
• Document any abnormal signs, their location, and clinical significance.

8. Practical Tips

• Maintain eye contact and observe facial expressions for pain cues.
• Synchronize palpation with the patient’s breathing – press gently during expiration.
• Practice the sequence repeatedly to develop speed and accuracy.
• Ensure the patient is well‑hydrated before percussion and auscultation for optimal sound transmission.

This structured approach ensures a thorough, objective, and reproducible abdominal examination, reducing the need for video review.

A systematic, step‑by‑step abdominal exam—starting with consent, followed by inspection, palpation, percussion, auscultation, and targeted special tests—provides reliable clinical information and allows accurate diagnosis without needing to watch the original video.
