Stomach Flashcards
How do we avoid trauma during stomach procedures?
Appropriate instruments, stay sutures and atraumatic needles. Want to preserve blood supply and ensure good haemostasis.
A dog has just undergone surgery and is in recovery. How long should we wait until drinking and feeding resumes?
12 hours water & glucose.
Highly palatable low residue high digestible food every 4 hours.
Resume normal diet gradually.
When does normal strength return to stomach during healing?
14 days
Describe chronic gastric outflow obstruction.
Cause- pyloric hypertrophy or tumours
Causes chronic vomition.
Y-U pyloroplasty, excise to restore lumen diameter.
When would you do gastrotomy?
FB removal, biopsy, mucousa inspection
How do you determine wall viability?
Serosa colour
Gastric wall perfusion
Vessel
Palpation
Describe gastric dilatation volvulus where it’s common & clinical signs.
Twisting of stomach.
Usually large breeds.
Salivation, restless, abdominal distension, retching
Why does dilatation occur after volvolus?
First stomach twists then fluid & gas accumulates.
How does GDV cause peritonitis?
Ulcerations from gastric acid can perforate & cause peritonitis
Why do you get endotoxaemia from GDV patient?
Decreased hepatic circulation so endotoxins/bacteria in GIT cannot be removed
What is the most common rotation of GDV?
220-270 degrees clockwise
Pylorus & duodenum go ventral & left
Describe pre-operative, operative & post operative treatment of GDV.
Preop- stabilise, gastric decompression.
Op- Derotate stomach & spleen, gastric wall viability, splenectomy, haemostasis, gastropexy, Y-U pyloroplasty, abdominal lavage. ALWAYS do exploratory celiotomy.
Postop - Amoxicillin & metronidazole prevent sepsis & peritonitis. Nil per os 3days.
What’s the best gastropexy techniques?
Incisional
Smeak costal
Circumcostal
Which condition causes vomiting of undigested food 6-8 hrs after eating usually projectile vomiting?
Gastric stasis - motility inhibition
How do we treat gastric stasis?
Diet
Metoclopramide
Cisapride
What causes gastric stasis?
Primary gastric disease Hypokalaemia Chronic dilatation Chronic pyloric obstruction Decreased gastric emptying
