Palpation of the belly for pathology is a fine art.
One tool for outlining the solid organs of the belly or detecting large amounts of blood vs air is the scratch test.
It works because sound transmits differently through solid vs hollow objects.
a stethoscope, The better the quality the better the “resolution” especially if you have post deployment hearing…….
a pen, I prefer a sharpie but a ball point works fine most days
Try this at home on your self or a family member in 3 easy steps.
1) Take the scope and place it just below the right rib cage on the mid clavicular line for starters. This is right over the liver…. on a good day.
2) Next begin using that high tech fingernail to scratch the skin surrounding the stethoscope. Listen for the initial change in sound volume.
3) Mark with the pen where the sound volume changes.
Hey! it is shaped like the liver! A dense blood filled object.
A normal adult liver should be about 7cm tall at the mid clavicular line.
You will hear the bone if you place it over the rib, this is not helpful.
This test can also detect an enlarged spleen. Normal is not detectable below the left costal margin.
A large hemoperitineum can be detected as well as a large stool.
The test is not needed to detect common autologus cranio rectal transplantation as that malady is self evident when the patient speaks.
Good luck and hope this test works as well for you as well as it has for me in austere settings.
