cancer!
obstruction xray imaging will show what?
xray: air/fluid levels and bowel loops
what can you txt a volvulus with?

sigmoid volvulus
symptoms of volvulus
crampy abd pain that comes and goes, constipation high-pitched bowel sounds

intestinal ischemia from volvulus can lead to … (Weeds)
intestinal ischemia leading to edema, petechial hemorrhages, necrosis, gangrene, perforation.
best imaging for volvulus? what do you see?
CT- shows mural edema, necrosis as obstruction persists (bowel wall thickening- means ischemia)
if theres a perf you see free air
xray of obstruction/volvulus may show what kind of pattern?
“stair-step” of gas-filled loops
what do you need for Dx of obstruction?
