The liver and spleen are carefully evaluated for size, consistency, and tenderness, as enlargement of these organs frequently points to the etiology of the fluid buildup. This systematic assessment goes beyond simply noting a distended abdomen; it involves specific maneuvers to confirm the presence of fluid, estimate its volume, and identify the underlying cause.
Ascites Versus Other Abdominal Fluids: Key Exam Differences
The fluid will shift, creating a new dullness on the dependent side. Shifting dullness is a classic maneuver where the patient lies supine; the clinician percusses the abdomen until the fluid line is identified, then quickly rolls the patient to the side.
A positive fluid wave test involves the patient pressing their hands firmly against the midline abdomen while the clinician strikes one flank; the impulse is transmitted through the fluid and felt on the opposite side, indicating a substantial volume of intraperitoneal fluid. The clinician feels for the abdominal wall veins, which may become prominent and engorged, often directing upward toward the chest in cases of portal hypertension.

Stretch marks, or striae, may be visible if the distension has occurred rapidly. The practitioner must differentiate between true fluid accumulation and simple obesity or gaseous distension, where the fluid wave and shifting dullness tests would be negative.
