What vessels do we worry about being compressed with GDV?
|
Caudal vena cava
Portal vein |
|
Why do we worry about hypovolemia and septic shock with GDV?
|
Because the caudal vena cava and portal veins are compressed
|
|
How can you tell if you completely untwisted a GDV?
|
Look at the splenic vasculature
|
|
The majority of vascular damage to the stomach with GDV is in which anatomical region?
|
Fundic
|
|
Which two organs do you really want to inspect well after untwisting a GDV?
|
Stomach
Spleen |
|
True/false: Gastroplexy prevents both GDV and bloat.
|
False, only GDV
|
|
Which portion of the stomach is sutured to the right body wall with gastroplexy?
|
Pyloric antrum
|
|
What is prophylactic gastroplexy?
|
Doing a gastroplexy prior to an animal having GDV (i.e. you might want to offer it in a large breed deep chested dog at the time of spay/neuter)
|
|
Name some breeds that are susceptible for chronic hypertrophic pyloric gastropathy.
|
Boxers
Bostons Shih Tzu Maltese |
|
What is the best way to diagnose chronic hypertrophic pyloric gastropathy?
|
Endoscopy
|
|
What surgical procedure would you use to correct chronic hypertrophic pyloric gastropathy?
|
Pyloroplasty - a full thickness incision is made and tissue is reoriented to increase the diameter of the outflow tract
|
|
Which form of pyloroplasty has the best results?
|
Y-U technique
|
|
True/false: When you do a pyloroplasty to correct chronic hypertrophic pyloric gastropathy, you should always go ahead and get a full thickness biopsy.
|
True
|
|
An incision into the lumen of the stomach is AKA:
|
Gastrotomy
|
|
Creation of an artificial opening into the gastric lumen is AKA:
|
Gastrostomy
|
|
Permanent adherence of the stomach to the body wall is AKA:
|
Gastropexy
|
|
You should withold food for how many hours prior to performing a gastric surgery?
|
8-12 to be sure the stomach is empty
|
|
Why are bacteria scarce in the stomach compared to other parts of the GIT?
|
Due to low pH; so those with healthy immune function rarely require antibiotics following gastrotomy
|
|
The esophagus enters the stomach through the:
|
Cardiac ostium
