Hemorrhagic gastroenteritis (HGE) is a disease of dogs characterized by sudden vomiting and bloody diarrhea. The symptoms are usually severe, and HGE can be fatal if not treated. HGE is most common in young adult dogs of any breed, but especially small dogs such as the Toy Poodle and Miniature Schnauzer. [1] It is not contagious.
Bowel obstruction, also known as intestinal obstruction, is a mechanical or functional obstruction of the intestines which prevents the normal movement of the products of digestion. [2] [5] Either the small bowel or large bowel may be affected. [1] Signs and symptoms include abdominal pain, vomiting, bloating and not passing gas. [1]
Dogs are ten times more likely to be infected than humans. The disease in dogs can affect the eyes, brain, lungs, skin, or bones. [15] Histoplasmosis* is a fungal disease caused by Histoplasma capsulatum that affects both dogs and humans. The disease in dogs usually affects the lungs and small intestine. [16]
Biofeedback has been shown to improve symptoms (improved frequency of bowel movements, reduced straining) and also reduce need for laxatives, [16] and patients stop needing to self-digitate. [24] Biofeedback can successfully treat abnormal contraction and relaxation of muscles in the anorectum during defecation. [ 24 ]
Pouchitis is an umbrella term for inflammation of the ileal pouch, an artificial rectum surgically created out of ileum (the last section of the small intestine) in patients who have undergone a proctocolectomy or total colectomy (removal of the colon and rectum). [1]
Treatment targets nutritional support, improving intestinal motility, and minimizing surgical intervention. [4] Bacterial overgrowth of the small intestine can occur in chronic cases – presenting as malabsorption, diarrhea, and nutrient deficiencies [12] – which may require the use of antibiotics.
Initial treatment for sigmoid volvulus may occasionally occur via sigmoidoscopy or with a barium enema. [3] Due to the high risk of recurrence, a bowel resection within the next two days is generally recommended. [3] If the bowel is severely twisted or the blood supply is cut off, immediate surgery is required. [1]
Intussusception is a medical condition in which a part of the intestine folds into the section immediately ahead of it. [1] It typically involves the small intestine and less commonly the large intestine. [1] Symptoms include abdominal pain which may come and go, vomiting, abdominal bloating, and bloody stool. [1]
