In gastroenterology, the<unk>  is a physical examination maneuver that can be used to detect the presence of ascites.
It is useful for detecting small amounts of ascites -- as small as 120 mL; shifting dullness and bulging flanks typically require 500 mL.
In relation to auscultatory percussion, the<unk>  is more specific, but less sensitive.
