Diseases Of The Stomach Flashcards
What are the potential causes of gastritis?
Drugs, hyperacidity, infectious, primary gastritis, stress/ exercise induced, systemic
Acute gastritis
CS <2 weeks
Dogs > cats
Vomiting food +/- bile, inappetence
What are the possible causes of acute gastritis?
(Normal PE)
Dietary indiscretion
Food intolerance
Gastric FB
Stomach worm
Tx of acute gastritis with normal PE
Small amounts of liquid
Deworm
Easily digestible diet then gradual transition to normal diet
Protectants/ absorbants
Prognosis for for acute gastritis if PE normal
Good and self- limiting
Complete recovery
more dx if progression
Diagnostics for acute gastritis if PE abnormal
Coagulogram with hematemesis
Abnormal US or rads
Cortisol or ACTH, total T4 (cats)
Gastric mucosal bx and histopathology
Tx for for acute gastritis if PE abnormal
IV fluids for dehydration and abnormal electrolytes
Antiemetics (if no obstruction)- maropitant
Antacids and gastroprotectants
Deworm
Diet therapy
Chronic gastritis
CS > 2 weeks
Idiopathic and adverse food reaction
Inflammatory
Bx required
MOA of chronic gastritis
↑ pro inflammatory mediators
↓ immunomodulatory mediators
Inflammation
Common causes of chronic gastritis
Metabolic disorder, parasitic, neoplasia, infectious agent
CS of chronic gastritis
Intermittent persistent vomiting
Hematoemesis
WL
Anorexia/ hyporexia
Dermatological signs: hypersensitivity and nutritional
Chronic gastritis differentials
Acute gastritis
Idiopathic gastritis/ dietary intolerance
Inflammatory gastritis
Pyloric stenosis
Gastric mass (neoplasia or granuloma)
Gastric mucosal hyperplasia
Ruling out the metabolic causes of vomiting (chronic gastritis)
CBC, serum chemistry, urinalysis
Dog: cortisol/ ACTH, TLI, CPLI
Cat: total T4
Pre and post bile acids
Bile culture
Endoparasite dx (chronic gastritis)
Fecal cytology
Sheathers
Zinc sulfate
Baerman technique
Deworm
Fenbendazole trial
Tests for infectious causes of vomiting (chronic gastritis)
Dog: Pythian serology
Cat: Dirofilaria Ag and Ab tests, FeLV/ FIV
Histoplasma urinary Ag test
Tests for chronic gastritis
Bx: endoscopy, laparoscopy, exploratory laparotomy
Histopathology +/- immuniphenotyping
Inflammatory features of chronic gastritis
Lymphocytic/ Plasmacytic*
Eosinophilic
Pyogranulomatous
Suppurative
Lymphoid folliculat hyperplasia
Neoplasia
What is lymphocytic/ plasmacytic (chronic gastritis) seen with
Seen with IBD (chr. inflamm enteritis/ CIE)
Food responsive GI dz
High exercise-induced gastroenteritis (alaskan shed dogs)
Dx lymphocytic/ plasmacytic
Histopathology
Distinguish from lymphoma with immunophenotyping
