What it is

Palpation is the last stage of the abdominal exam: it comes after inspection, auscultation and percussion so that bowel sounds are not altered and painful steps come last. It is first light, to find tenderness, guarding and wall masses, then deep, to outline organs and masses. Telling voluntary from involuntary guarding (rigidity) is key: the second signals peritoneal irritation and usually needs surgical assessment.

Landmark anatomy

The rectus abdominis, obliques and transversus abdominis form the wall; their reflex contraction (guarding) protects an inflamed parietal peritoneum.
The parietal peritoneum has somatic nerve supply from the lower intercostal and lumbar nerves: it localizes pain well and triggers rigidity.
In a thin person the aorta, the liver edge, the sigmoid colon and the lower pole of the right kidney may normally be felt.

Technique, step by step

Patient supine, arms at the sides, knees flexed to relax the wall; the examiner's hands warm and nails short.
Ask where it hurts and start in the quadrant farthest from that spot.
Light palpation: with the palm and fingers together, press the wall down about a centimeter with gentle circular movements across all nine regions.
While palpating, watch the patient's face for pain and feel whether the muscles tense under your hand.
If the wall is tense, distract the patient or ask for deep breaths through the mouth: if it eases it was voluntary; if it persists it is involuntary.
Deep palpation: with one hand over the other, press deeper and slowly to outline organs and masses.
Feel the aorta with both hands on either side of the midline above the umbilicus and estimate its width.
Palpate the liver, spleen and kidneys with their specific techniques, and check the groins and scars for hernias.
Leave painful maneuvers (rebound, specific signs) for the end.

Abnormal findings

Localized tenderness with guarding: an underlying inflammatory process (appendicitis in the right iliac fossa, cholecystitis in the right hypochondrium, diverticulitis in the left iliac fossa).
Generalized rigidity: diffuse peritonitis, for example from a perforated ulcer.
Severe pain with a soft, barely tender abdomen: suspect mesenteric ischemia.
Hard, irregular mass: cancer; a mass that moves with breathing belongs to the liver, spleen, gallbladder or kidney.
A widened, expansile palpable aorta: abdominal aortic aneurysm.

Common errors

Cold hands or starting at the painful spot cause voluntary guarding and hide findings.
Digging in with the fingertips instead of using the palmar surface of the fingers.
In older adults, immunosuppressed people or those on corticosteroids, guarding may be absent even with peritonitis.
Palpation does not replace imaging when clinical suspicion is high.

Test yourself

Think of the answer, then tap the question to see it.

How do you tell voluntary from involuntary guarding?

Voluntary guarding eases when the patient is distracted or breathes deeply; involuntary guarding is a sustained reflex contraction that persists and signals peritoneal irritation.

Why start palpating away from the painful area?

To avoid triggering guarding and losing the patient's trust at the outset, so the rest of the abdomen can be assessed relaxed.

Which features of an abdominal mass do you describe?

Site, size, shape, consistency, tenderness, movement with breathing and whether it pulsates.

What does a board-like abdomen suggest?

Generalized peritonitis, classically from perforation of a hollow organ such as a peptic ulcer.
