DISEASES OF THE
STOMACH
Stomach Diseases: Acute Gastritis
Acute Gastritis
◦
◦
Commonly seen in dogs
Spoiled food
Change in diet
Food allergy
Infections (bacterial, viral, parasitic)
Toxins (chemicals, plants, drugs, organ failure)
Foreign objects
Signs
Anorexia
Vomiting (maybe dehydration)
Painful abdomen
Hx of diet change, toxin ingestion, infection, parasites
Acute Gastritis
Dx
◦
Hx and PE
◦
CBC, Chem Panel to assess dehydration, metabolic imbalance, organ failure
Rx
◦
◦
NPO until vomiting stops
4-6 sips of water q1h
Fluid therapy (SQ or IV)
Gradually start feeding
◦
◦
Bland food (Hill’s I/D, boiled chicken/rice)
Antiemetics
Maropitant (Cerenia)
Metoclopramide (Reglan)
Coating agents
Sucralfate
◦
H2-blockers (famotidine, ranitidine, cimetidine)
◦
Antibiotics—often prescribed, rarely needed
Acute Gastritis
Client info
Avoid abrupt changes in diet
Gradually
mix new food in with old (1 wk)
If pet vomit 2-3 times, NPO x 24 h; if it continues
see vet
Dogs and cats do not need variety
Immune-Mediated Inflammatory Bowel Disease
(Chronic gastritis, Enteritis, Colitis)
A decreased tolerance to the diet or to the normal flora
results in accumulation of inflammatory cells in lining
of stomach, Small Intestine, or Large Intestine
Clinical Signs
Chronic vomiting, wt loss
Diarrhea, straining to defecate, mucus in stool
Immune-Mediated Inflammatory Bowel Disease
(Chronic gastritis, Enteritis, Colitis)
Diagnosis
Fecal to r/o parasites
CBC, Chemistry panel, urinalysis to r/o metabolic
disorder
FeLV, FIV to r/o those diseases
Endoscopy of stomach, SI, and colon, and biopsy for
definitive diagnosis
Immune-Mediated Inflammatory Bowel Disease
(Chronic Gastritis, Enteritis, Colitis)
Treatment
Azathioprine—immunosupressant
Cyclophosphamide—inhibits immune system response
Sulfasalazine—a sulfa drug with anti-inflammatory/antibacterial
effects
Most effective against colitis
Metronidazole
Prednisone
Hypoallergenic diet
Free from preservative, additives
Highly digestible protein (rabbit, lamb, duck, chicken)
Homemade diets with rice base
Some commercial diets are available
Inflammatory Bowel Disease
Client
info
Definitive
Life-long
diagnosis is through biopsy
condition
Immunosuppressive
drugs have side-effects
(PU/PD/PP, wt gain, skin/urinary infections)
Use
lowest dose that provides effect
Stomach Diseases:Gastric Ulceration
Usually a result of long-term NSAIDs (aspirin, ibuprofen,
phenylbutazone)
Signs
Vary from asymptomatic to vomiting
blood
Anemia, edema
Melena
Anorexia
Abdominal pain
Septicemia if perforation occurs
Gastric Ulceration
Dx
X-ray using contrast medium (Barium) to show
ulceration in stomach lining (caution if perforation is
suspected)
Endoscopy
Gastric Ulceration
Rx
◦
Fluid therapy for dehydration
◦
NPO (as before)
◦
Coating agents/antacids
◦
Cimetidine—H2 antagonist (↓ HCl production)
◦
Omeprazole—↓ HCl production (proton-pump inhibitor)
Client info
◦
Do not use NSAIDs without veterinary supervision
◦
Give NSAIDs with meal/antacids
Stomach Diseases: Gastric
Dilatation/Volvulus
Primarily a disease of large, deep-chested dogs (2-10 yrs)
Dilation—gas filled; Volvulus—twisted along longitudinal axis
Cause: Food/exercise? Etiology unclear
Signs
◦
Abdominal pain/distension
◦
Weakness, collapse, depression, nausea, salivation
◦
Increased HR, RR – may lead to arrhythmias
Gastric Dilatation/Volvulus
Gastric Dilatation/Volvulus
Stomach Diseases: GDV
Diagnosis
◦
PE shows depressed, weak animal with dpoor
perfusion (↑CRT)
◦
X-rays show air filled stomach- “double-bubble”
◦
ECG may show vent arrhythmia or sinus
tachycardia
◦
CBC and Chem panel necessary to assess
electrolyte levels and pH imbalances
Gastric Dilatation/Volvulus
Treatment
◦
Goals
Decompress stomach
◦
◦
◦
◦
Pass stomach tube
18 gauge needle
Stabilize patient (fluids, electrolytes, ECG)
Rx for shock
IV fluids
Corticosteroids
◦
Antibiotics
Prepare for Sx
Surgery ASAP
Gastric Dilatation/Volvulus
Gastric Dilatation/Volvulus
Post-Op
ECG
Blood
Pain
pressure
management
Monitor
urine output
Antibiotics
Maintain
fluids (oral, IV)
Gastric Dilatation/Volvulus
Client info
Avoid
large meals
Limit
exercise after meals
Feed
high-quality protein diet
Tack-down
procedure not 100% preventative
Gastric Neoplasia
Most common malignant neoplasia in dogs is adenocarcinoma; in cats
lymphoma
Signs
Wt loss
Vomiting w/ or w/o blood
Obstruction
Usually seen in older animals
Dx
Endoscopy and biopsy for diagnosis
X-ray with Barium contrast
Gastric Neoplasia
Treatment
Surgery is treatment of choice
Many
tumors are too far advanced (inoperable)
Chemotherapy
Radiation less successful for gastric tumors
Client info
Prognosis is poor; gastric neoplasia is a fatal disease
Supportive care, control of vomiting, good nutrition
are needed for these animals
