What is the difference between light and deep abdominal palpation?

Light palpation is superficial, pressing to approximately 1 cm depth to identify superficial organs, masses, and abdominal wall crepitus. Deep palpation applies firm pressure to examine internal organs like the liver, kidneys, spleen, and stomach, and can detect organomegaly and aortic aneurysm. Both techniques are essential for comprehensive abdominal assessment.

How should you position and prepare a patient before performing abdominal palpation?

Position the patient supine with proper draping to maintain modesty. Explain the procedure and obtain consent. Ask the patient to identify painful areas and examine those last to minimize guarding. Encourage abdominal relaxation by having the patient bend their knees and breathe with their abdomen. These measures reduce voluntary muscle resistance and improve exam accuracy.

What technique should you use when examining the liver during abdominal palpation?

Place your right hand lateral to the rectus muscle below the liver's percussed border, fingers oriented cephalad. Ask the patient to take a deep breath; the liver descends and its edge meets your fingertips. Continue moving upward to feel the edge, typically a few centimeters below the right costal margin. Note the edge's texture and regularity as you palpate.

How do you detect an enlarged spleen during palpation?

A normal spleen is rarely palpable, but an enlarged spleen displaces downward below the rib cage and medially across the abdomen. Starting in the left lower quadrant, move your fingers slightly upward with each inspiration and expiration, pressing downward and toward the patient's head. If not felt initially, repeat with the patient lying on their right side.

What is the two-hand palpation technique and when should it be used?

In two-hand palpation, place your non-dominant hand on top of your dominant hand. Keep the lower hand relaxed and press with the upper hand's fingers on the distal phalangeal joints of the lower hand. This technique is useful in obese patients or when voluntary muscle resistance is present, allowing one hand to produce pressure while the other feels the underlying structures.

How do you perform kidney palpation to detect enlargement?

Position your left hand at the costophrenic angle and palpate with your right hand pressing forward, attempting to capture the kidney between your hands. Ask the patient to take a deep breath and feel for the kidney on inspiration. If felt, ask the patient to exhale and hold their breath to feel the kidney return to its expiratory position. Repeat on the left side.

What information does abdominal palpation provide during patient assessment?

Abdominal palpation identifies areas of tenderness, organomegaly, and tumors, providing valuable information about problem localization and severity. It integrates findings from history and other abdominal exam components to guide subsequent diagnostic steps. For skilled examiners, palpation assesses both large superficial organs and smaller deeper structures, though patient anatomy may affect examination difficulty.

Abdominal Exam III: Palpation

1. Light palpation

Light palpation allows for determination of the areas of tenderness and abdominal wall resistance due to rigidity (involuntary muscle spasm) or guarding (voluntary contraction of the abdominal wall musculature). It also permits identification of the superficial organs or masses, or, much less frequently, crepitus of the abdominal wall (caused by gas or fluid within the subcutaneous tissues).

Make sure that the patient is positioned correctly, and explain the procedure.
Ask the patient to indicate the area of pain or tenderness, and examine this area last (to avoid generalized abdominal resistance due to apprehension). Examine the painful areas gently, and don't try to re-elicit the pain.
To improve the abdominal relaxation, you might need to have the patient change position or lie with the knees bent. You might also need to ask the patient to breathe abdominally, while you move your hand up and down and trying to palpate as the abdominal wall moves during the inspiration/expiration cycles. These measures usually decrease voluntary guarding.
Using your dominant hand, keep your fingers together and press to a depth of approximately 1 cm using the pads (flat surfaces) of your fingers with a gentle circular motion.
Examine all of the abdominal regions, moving in a clockwise direction. Slightly lift your hand as you move to a different spot, and avoid sudden jabs.
If the patient is ticklish, ask place the patient's hand under yours, and then slip your hand underneath the patient's hand after a few moments.
As you palpate, watch the patient's face for any signs of discomfort or pain.
Note the presence of irregularities of the abdominal wall, superficial organs or masses, and crepitus (crunching feeling during palpation produced by gas or fluid within subcutaneous tissues).

2. Deep palpation

While the superficial palpation provides information about potential areas of tenderness, superficial structures, and the abdominal wall, deep palpation permits inspection of the internal organs and delineation of the intra-abdominal masses. Additional areas of tenderness could be identified by deep palpation as well.

Start with the quadrant opposite to the one where the pain is located. Continue watching the patient's face for signs of pain or discomfort as you proceed.
Place the flat of your hand on the abdominal wall, and apply firm pressure downward and longitudinally. Keep your fingers relatively fixed on the skin, and use a rolling motion.
Use the two-hand palpation in obese patients or if voluntary muscle resistance is present.
1. Place your non-dominant hand on top of your dominant hand.
2. Keep the lower hand relaxed, and press with the fingers of the upper hand on the distal phalangeal joints of the lower hand. This way, one hand produces the pressure while the other is used to feel.
Palpate over the all four abdominal quadrants. The palpable abdominal organs include the liver, caecum, sigmoid colon, and, sometimes, the transverse colon and stomach. Enlarged kidneys, gall bladder, spleen, and aortic masses might be palpable as well. (Figure 1)

3. Liver palpation

The lower edge of the liver can be palpable on inspiration about 3 cm below the right rib cage. The liver palpation can be performed with one hand or bimanually, and in the case of obese patients, the so-called "hooking" technique might be helpful as well.

One-hand liver palpation
1. Place your right hand on patient's abdomen, lateral to the rectus muscle, well below the level of percussed border of liver dullness.
2. Orient your fingers towards the patient's head or slightly diagonally towards the midline. Press your fingers firmly in and up (towards the patient's head).
3. Ask the patient to take a deep breath. On inspiration, the liver descends, and its edge meets the fingertips of the palpating hand.
4. Continue palpating, moving your hand toward the coastal margin until you feel the liver edge (usually a few cm below right costal margin). Note liver edge texture and regularity. Slight tenderness on palpation is normal.
5. When your fingers meet the liver edge, slightly reduce the pressure on the abdominal wall while the patient is still taking a deep breath in. This maneuver allows the examiner to feel the anterior liver surface as it slips under the finger pads. Make a note of the consistency of the liver surface-nodes, granularity, etc. (Figure 2)
Bimanual liver palpation
1. Place your left hand posteriorly at the level of the patient's two lower ribs, and gently press upward to elevate the liver into a more accessible position.
2. Ask the patient to take a deep breath, and perform palpation with your right hand as described above.
The "hooking" technique
This can be helpful when the liver is not palpable by the standard techniques.
1. Stand on the right of the patient, facing the patient's feet.
2. Place your flexed fingers over the edge of costal margin.
3. Ask the patient to take a deep breath and try to feel the liver edge as you press downward and upward (towards the patient's head).

4. Spleen palpation

A normal-sized spleen is rarely palpable. Occasionally, the tip of the spleen can be felt at the left costal margin. When the spleen is significantly enlarged, it displaces the stomach and expands downward below the rib cage and medially across the abdomen, and might be felt as low as at right lower quadrant (Figure 3).

Ask the patient to take a deep breath; then, try to palpate the lower margin of the spleen during expiration.
Starting in the right lower quadrant, move your fingers slightly up with each inspiration-expiration.
Palpate pressing down and towards the patient's head and then releasing, in the same motion as for palpating of the lower edge of the liver.
If the spleen is not felt, repeat the exam with patient lying on the right side.
Some examiners use the bimanual palpation technique, during which the palpation is performed with the right hand while the left hand of the examiner is placed behind the left rib cage, and is pressed on the ribs and soft tissues upwards.

5. Kidney palpation

Kidneys are retroperitoneal organs and are rarely palpable in a healthy adult. Sometimes enlarged kidneys can be assessed using bimanual "balloting" technique (derived from the French word ballotte, meaning "toss"). The palpating hand is positioned in the upper quadrant lateral to the rectus muscle, while the other hand is placed at the costophrenic angle and is pressing upwards (thus bringing the kidney closer to the anterior abdominal wall) (Figure 4). The maneuver is performed on deep inspiration, when the kidneys descend, and one might feel their lower poles.

To palpate the right kidney, ask the patient to take a deep breath, and palpate with your upper hand while pressing forward with your lower hand position at the right costophrenic angle.
Attempt to "capture" the kidney between your hands, or feel it with your upper hand.
If you feel the kidney on inspiration, ask the patient to exhale deeply and hold the breath for a moment. You might feel the kidney moving back to its expiratory position.
Repeat the maneuver on the left side. Some examiners prefer to stand on the left side of the patient, and palpate with the left hand while balloting the kidney with the right hand; other examiners palpate with the right hand, reaching with the left hand over the patient.
