Inflamm. of stomach m. membranes causing abnormal. motility, vomition, anorexia & abd. Pain
It may be acute or chronic. It may be assoc. w. enteritis.
Overfeeding causing Gast. dilatation. & gastritis.
Physical agent (Very Cold or very hot food).
Chemical agents (arsenic, lead, copper, mercury ).
Foreign bodies. Damaged, moldy, fermented feeds.
Causes of Gastritis
Causes of gastritis Bacterial agents (oral necro-bacillosis,
Hrgc entero-toxem., colli-bacillosis & salmonell. Leptosp. & hepatitis (dog)
Viral agents (RP, MD). Fungal (Moniliasis). Parasites in cattle (Trich., ostertagia,
hemonchus, paramphist.) In horse: Larvae of Habronema
megastomum.
Helicobacter
Signs of acute gastritis:1-Vomition: mucoid, bloody in chemical or posoin.
gastritis. Periodical in allergic enteritis of dog. Expulsive in decomposed food
gastritis.
2-Reduced appetite & Excess. thirst.
3-Rank smell breath.
Signs of gastritis:
4-Diarrhea may assoc. gastroent. or soft pasty feces.
5- Abdominal pain.
6-Dehydration and alkalosis, emaciat.
In Chronic gastritis Signs are Less severe with depraved
appetite. Sporadic vomiting.
Diagnosis of Gastritis History of over feeding or feeding abnormal
food.
Gastritis should be diff. from: Gast. dilatation, in which vomiting which is
more projectile. Esoph. Obst: vomitus is not acid or rancid. Intest. Obst.: Vomitus is alkaline and
containig bile acids.
Treatment of Gastritis
Gast. Sedatives: Kaolin, pectin- charcoal. Bismuth sub nitrate. Mg. hydroxide or Mg. carbonate.
Gast. Astringents: Mix. of Tannic acid and Catechu. Gentamycin / sulphaguandin
Treatment of Gastritis
Fluid and nutrition therapy: I.v. Ringer sol. (Na, K, Ca, Mg). Glutamic acid.
Anti-emitic (dog) Vit. B6 (5-60 g/ other day). or Diphenylhydramine Hcl
Evacuation of stomach in G. dilatation: laxative (Mineral oil)
Easily dig. Palatable food
Gastric UlcersUlceration of G. mucosa means removal of some parts of the protective m. m of the stomach.
It is charct. by signs of abdom. pain, anorexia, other GIT motility disturb. (diarrhea, constiptaion).
It may cause gastric bleeding and by turn emaciation and anemia.
Causes of Gastric Ulcers Traumatic causes.
Long feeding of corrosive or chemical substances.
Sequllae to chr. Vagus indigestion.
Untreated Gastritis
Long standing parasitic inf. (Gastrophilus, Habronema megastoma)
Other causes:
Stress of grain overfeeding.
Uremia.
Long standing Steroid therapy.
Hyperparathyroidism (25%).
Coexistent duodenal ulcer disease.
Signs of Gastric ulcer
Signs of abdomen. pain, anorexia, diarrhea or constipation.
Mucoid vomiting in dog, cat and may bloody (Hematemesis).
Severe hemorrhagic anemia.
Black, pasty, soft feces (Melana).
Emaciation, lassitude and death.
Bleeding Gastric ulcerBleeding Gastric ulcer
Diagnosis of G. UlcerHistory of abd. Pain, emesis or hematemesis.
Signs of anemia.
Leucocytosis and neutrophilia
Fecal analysis: Hemonchus, Gastrophillus, Habronema)
X- ray examination.
Endoscopy of gast. mucosa.
Gastric mucosa (G. Ulcer)Gastric mucosa (G. Ulcer)
Treatment of G. Ulcer.Prolonged use of protective and astringent drugs.
To stop bleeding inject Ca & Vit. K.
Inject hematincs or blood transfusion if necessary.
Easily digestible food or parentral feeding.
Surgical repair may be useful.
HealingMost gastric ulcers clear completely in 6-8 weeks.
With healing, ulcer ▼ in size and is more likely to appear linear
Radiating folds become more prominent and extend to crater.
Between 50-90% of healed gastric ulcers produce visible scars on Double Contrast study
Gastric ruptureOccurs in the great curvature of horse stomach due to sever g. dilatation.
Gastric rupture
Causes:
Severe impaction and indigestion.
Strongly spoiled and ferment. Food.
Complication of G. ulcer.
Sever attach of spasmodic colic.
Clinical findings.
Severe abdominal pain.
Followed by relief and vomition.
Profuse sweeting.
Dog sitting position.
Inclination of head
Hypothermia and death.
Abdominal pain
Abdominal pain
