UGIS Flashcards
The size, shape, and position of the stomach depend on (1) and vary with (2) and (3)
- body habitus
- posture
- amount of stomach contents
Different body habitus and percentage
Hypersthenic (5%)
Sthenic (50%)
Hyposthenic (35%)
Asthenic (10%)
When identifying the types of stomach, always take note of these two stomach anatomy
- Incisuer angularis/ angular notch
- Pylorus/ pylori bulb
Tyeps of stomach
- Eutonic
- Hypotonic
- Steer Horn
Eutonic stomach common to what body habitus?
Sthenic
Hypotonic stomach common to what body habitus?
Asthenic and hyposthenic
Steer horn stomach common to what body habitus?
Sthenic and some hyposthenic
Pylorus and IA are at the same level
Eutonic
Pylorus is above the IA
Hypotonic
IA is above the pylorus
Steer Horn
Subtypes of stomach
- Transverse
- Infantile
- Cascades
Stomach subtype common to hypersthenic habitus
Transverse
Stomach lies horizontally in relationship w LA of of body
Transverse
Fundus is at the level of the body
Transverse
Stomach subtype common to infants
Infantile
Pylorus is behind the body
Infantile
Oblique or lat posn is use especially in spot-film
Infantile
Common to Sthenic or Hyposthenic habitus
Cascades
Fundus fills first and spills over
Cascades
Most uncommon subtype of stomach
Cascades
Stomach moves posteriorly and superiorly due to abdominal pressure and presence of liver superiorly; movement is more to the left
UGIS Prone position
RP when in prone position (UGIS)
est 2.5” from vertebral column
Stomach bn mammary lines;
fundus= within L mammary line;
pylorus= at R mammary line
UGIS Supine posn
Stomach moves toward anthrax inferiorly and anteriorly, and contect of stomach is deposited within antra portion of stomach
UGIS RAO Posn
Pylorus tends to move anterior to the body of stomach and take posterior part to cover retro-gastric portion
UGIS LAO Posn
Not ideal for retrogastric
UGIS LAO Posn
Stomach moves slightly posterior and pylorus is fixed w the body almost anterior than pylorus
UGIS Right Lat Rec
Stomach moves inferiorly because fo gravity, and moves anteriorly
UGIS Left Lat Rec
Fluid level is appreciated and possible demo of epigastric mass
UGIS Left Lat Rec
Barium fills body of stomach w fundus, and pylorus is filled w air
UGIS Pt in Prone
Ba fills fundus and pylorus, and body w air
UGIS Pt in Supine
Ba is appreciated w/in pylorus and antrum while body and fundus w air
UGIS Pt in RAO
Ba is within fundus and body while pylorus and antrum is w air
UGIS Pt in LAO
Ba flows towards pylorus and antrum and air is w/in the fundus and body
UGIS Pt in Lat Upright
1 glass barium introduced prior to the examination to demo extrinsic pathology
UGIS Sinle Ba Method
1 glass ba susp intoruced an hr before the exam and 1 glass again given during actual exam (to distend SI and stomach)
UGIS Double Barium
Thick ba to demo mucosal lining; thin to demo extrinsic pathology
UGIS Fractionated
Single and double contrast taken at a time in a day (double then single phase where 15% wt/volume of Ba s given for single side
UGIS Biphasic Examn
