enterocolitis - due to poop just sitting in colon
When trying to tidentify Hirschsprung's disease early, what diagnostic studies are
preformed?
complete and careful history, x-ray, barium edema studies, anorectal manometric
examination, rectal biopsy to confirm diagnosis
What surgery should be anticipated for Hirschsprung's disease?
Soave pull-through
How does the Soave pull-through work?
the section of the colon without cells to help with peristalsis is removed, and then the
good part of the colon is pulled through
What should the nurse anticipate pre-op care would look like for a Soave pull-through?
saline enemas, antibiotics, colonic irrigations, abdominal measurements, prevent
enterocolitis
