wk 4 4 Benign colon conditions Flashcards
diverticular disease most likely to occur
sigmoid colon
main cause of diverticular disease
low fibre intake
define diverticular disease
mucosal herniation through muscle coat
clinical features of diverticulitis
LIF pain/tenderness
septic (fever,tachycardia)
altered bowel habit (may)
possible complications of diverticulitis 5
pericolic abscess perforation haemorrhage fistula (abnormal channel through 2 epithelial surfaces) stricture
all fistulas are complications of
a pericolic abscess
recurrent UTIs are suggestive of
fistula between bladder and colon - especially male
what else may be seen in a fistula between bladder and colon in male
passing of air during urination
bubbling
t/f uncomplicated diverticulitis does not need treatment
true
selflimiting
hartmanns procedure
removing diseased part of colon, then restore continuity by joining 2 areas
when would a laparoscopy be required for diverticulitis
when there is purulent peritonitis
surgery if fecal peritonitis
t/f h.pylori gives colitis
false
more likely to give gastritis
4 types of colitis
infective
ulcerative
crohns
ischaemic
symptoms of acute colitis
diarrhoea +/- blood
abdominal cramps
dehydration
sepsis
t/f haemoglobin will be reduced significantly if 1l of blood is lost
false
t/f weight loss and anaemia would be observed in chronic colitid
true
thumb printing is a sign of
severe mucosal inflammation
on RHS
lead piping is
lack of folds, seen usually at sigmoid
t/f treatment for ulcerative and crohns colitis begins as same
true
IV fluids
IV steroids - once diagnosed
GI rest
how would u know if the colitis had settled
not going to toilet lots of times observations settled (tachycardiac? tachypnoeac? ect)
crohns disease affects which part of colon
anywhere in colon
side usually affected by colonic angiodysplasia
right side
major GI bleed, what investigation
CT angiogram
volvulus - possible locations
twist
sigmoid
transverse
in neonates - whole of small bowel
differences between large and small intestine
large -
white strips of muscle (tenaie coli)
fat surrounding - appendages
signs of bowel obstruction
distension
absolute constipation
pain
vomiting
if vomiting came early what is this indicating
small intestine obstruction
if distension is late (days/weeks after constipation) what is this indicating
small intestine obstruction
which disease may become gangrenous
sigmoid volvulus
treatment for sigmoid volvullus
flatus twist - untwisting with endocopy
if not surgical resecrtion
pseudo-obstruciton
presents with signs symptoms of obstruction
no real mechanical obstruction
poor general health causes
electrolyte disturbance - organ failure
causes of constipation
low fibre
high caffeine
dehydrated
slow transit - motility problem
if patient gets better with laxatives, what does this suggest
can improve with dietary changes
thyroid and parathyroid problems can cause bowel problems t/f
true
