Stomach Flashcards
(19 cards)
What is the normal appearance of the stomach?
Normal size and content
Assessment should consider when the patient last ate.
What are the differentials for a fluid dilated stomach?
Gastric dilation and volvulus (GDV), functional ileus, pyloric outflow obstruction
It’s important to differentiate between these conditions.
What is the significance of taking 3 views of the abdomen?
It allows for better visualization of different parts of the GIT
Lateral and VD views help in assessing gas movement.
What are the two types of small intestine obstructions?
Mechanical obstruction and functional ileus
Mechanical obstructions are often surgical, while functional ileus can indicate gastroenteritis.
What is the diagnostic test of choice for pancreatitis?
Ultrasound (US)
Radiography is not effective for diagnosing pancreatitis.
What is the typical appearance of the pancreas on ultrasound?
Usually not seen; may appear as a hypoechoic area amidst severe steatitis
Steatitis appears as large hyperechoic areas.
True or False: Hypoadrenocorticism can be diagnosed through imaging.
False
Diagnosis requires bloodwork testing after observing small adrenal glands on US.
What is the most common reason for taking abdominal radiographs in practice?
Assessment of the stomach’s content
Plain radiographs are preferred for this purpose.
What should be done before performing radiography on a patient?
Fast the patient for at least 12 hours
Knowing the last feeding time is crucial for GIT interpretation.
What indicates the presence of a gastric foreign body?
Presence can cause vomiting without obstruction
Foreign bodies can be clinically silent and obscured by ingesta.
What is the normal gastric emptying time for liquid in dogs?
Maximum of 2 hours
Ingesta can remain in the stomach for up to 3 days.
What does a pyloric outflow obstruction look like on a left lateral view?
Formed soft tissue opaque foreign body in the pylorus
It may not be visible on the right lateral view due to fluid effacing.
What are some causes of fluid dilation of the stomach?
- Functional ileus
- Gastritis
- High obstruction (pyloric outflow obstruction or duodenal obstruction)
Differentiation may require ultrasound or contrast studies.
What is the key to diagnosing gastric dilation and volvulus (GDV)?
Identifying the pylorus in an abnormal dorsal location
The pylorus should be on the left side in DV views.
What is the normal wall thickness of the GIT determined by?
It cannot be determined on radiographs
Fluid in the lumen can make the wall appear thick.
What is the typical location of the pylorus in dogs compared to cats?
In dogs, it is on the right side; in cats, it is more caudal and on the midline
This affects the angle of the pylorus in lateral views.
Fill in the blank: Gastric emptying time in healthy dogs is highly variable and takes an average of ______.
3 days in hospital
What is the appearance of ingesta in the small intestine compared to the stomach?
Homogenous soft tissue opacity in the small intestine
Ingesta can be seen if there is a lot in the stomach.
What is the role of endoscopy in gastrointestinal imaging?
Not considered ‘diagnostic imaging’
It is limited to the stomach, proximal duodenum, and colon.
