week 9: Upper GIT Flashcards
what is an issue of imaging oesophagus
movement from peristalsis.
what is double contrast/ used for
barium + Co2 (i.e postive+negative)
- good for detecting small pathologies
what three impressions are on oesophagus
- aortic arch
- left main bronchus
- left atrium
Barium swallow indications
- dyshpasia (cant swallow)
- Anaphasia (wont swallow)
- reflux
- foriegn body
- cancer
- aspiration (food breathed into airways)
type of contrast used in barium swallow
can use single or double (efferecent grannules added after)
- thick for upper oesophagus, thin for lower
pathologies to know
- carcinoma,
- achalsia (reflux of lower oesophagus)/ bird beak deformity
- ## varices (caused by portal hypertension/cirhosis
body habitus and stomach shape
asthenic (skinny+tall)
hyposthenic
sthenic
hypersthenic (fat)
- hypersthenic will have most lateral stomach.
asthenic will have vertical stomach
is patient prone or supine (stomach barium position)
Prone= bariuim in pylorus (inferior) Supine= Barium in fundus (superior)
Barium Meal indications
reflux dyspepsia (indigestion) abnormal mass weight loss - will normally follow a barium swallow - aspiration (food breathed into airways)
PAtient prep for barium meal
- 8hr fast (food +water can mimic pathology)
- dont smoke or chew gum
and willl affect coating of stomach wall
Barium meal procedure
will comence erect (after barium swallow)
table goes horizontal. pt eats and swishes stomach around to coat walls
- may do trendlenberg
procedure: small bowel follow through
- barium meal
procedure: small bowl enema
very thin barium
catheter through nose/mouth to inject contrast
(bypass stomach)
how do we image small bowel
- small bowel enema (contrast bypass stomach)
- small bowel follow through (con in stomach)
