small intestine may be used as a continent mechanism for this patient? -
Ans✔✔-ileocecal valve
the ileocecal valve is smooth muscle that can function to prevent stoma output
from a continent diversion

is not necessary to sustain life. the small intestine villi are able to transform to
some degree and are able to increase the absorptive capacity taking on some
of the colon function when the colon is surgically removed
