In IBD there is an increase in the inflammatory cell population in the intestinal mucosa. The predominant inflammatory component can be lymphocytic-plasmacytic (most common type), eosinophilic, neutrophilic, or granulomatous. Primary causes of intestinal inflammation that should be considered include parasites, bacteria (specific agents or bacterial overgrowth), fungal disorders (e.g., Histoplasma, pythiosis), immune-mediated diseases, and food sensitivities. Many cases of IBD are likely idiopathic in nature. A presumptive diagnosis of IBD is made on the basis of history, physical exam and elimination of other disorders by laboratory tests and other studies such as radiography and ultrasonography. A definitive diagnosis can be made only by intestinal biopsy.

The bactericidal function of the hepatic reticuloendothelial (RE) system may be compromised in hepatic disease, especially if hepatic blood flow or oxygen tension is altered, resulting in septicemia. In hepatic bacterial encephalopathy, antibiotics are used to help reduce colonic bacterial numbers in an effort to decrease ammonia formation. Cholangitis has several causes, including bacterial invasion, which warrants antibiotic therapy. The regimen may be modified in accordance with specific information obtained from cultures of bile, hepatic tissue or blood. In cases of compromised hepatic RE function (e.g. hepatitis from any cause, septicemia) the antibiotics selected generally are directed against intestinal organisms.

In IBD there is an increase in the inflammatory cell population in the intestinal mucosa. The predominant inflammatory component in cats with IBD can be lymphocytic-plasmacytic (most common type), eosinophilic, or neutrophilic. Changes in mucosal architecture and cell morphology should also be noted (crypt lesions including abscesses, villus atrophy or fusion, edema, epithelial erosions or ulceration, fibrosis). The etiology of IBD is poorly understood. Primary causes of initiation and perpetuation of intestinal inflammation that should be considered include parasites, bacteria (specific agents including normal luminal bacteria or bacterial overgrowth), immune-mediated diseases, and food sensitivities. Many cases of IBD are likely idiopathic in nature.

Causes of anatomic obstruction include foreign bodies (linear or nonlinear), pyloroantral hypertrophic disease, polyps, intussusception, intramural masses (neoplasia, granulomatous enteritis, phycomycosis, satrictures, hematoma), and extramural compression (adhesions, strangulation, volvulus). Functional obstruction is caused by such disorders as adynamic ileus (e.g., surgical operations, peritonitis, sepsis, metabolic abnormalities). Intestinal obstruction can be classified as acute or chronic, partial or complete, and simple or strangulated.

Design-Prospective cross-sectional study. Setting-University teaching hospital. Samples-Seven commercial enteral diets for cats. Interventions-Labels were evaluated to determine if diets were intended to be nutritionally complete and balanced. One diet under storage techniques partially representative of clinical conditions was sampled on days 0, 1, 3, 5, and 7 of storage for aerobic bacterial culture. Measurements and Main Results-All 7 diets were analyzed for key nutrients and results were compared to Association of American Feed Control Officials (AAFCO) Nutrient Profiles for Adult Cats for maintenance and National Research Council recommended allowance (NRC-RA). From label information, 4 diets were classified as complete and balanced and 3 diets were classified as not complete and balanced. All 7 diets had at least 1 nutrient less than the AAFCO minimums and the NRC-RA. The total number of nutrients less than AAFCO minimums ranged from 3 to 9 (median = 4), with iron, potassium, and manganese being the most common. Concentrations of some nutrients were undetectable. None of the samples tested had a positive aerobic culture at baseline (day 0) or on subsequent samples from days 1, 3, 5, and 7 under any storage condition. Conclusions-None of the diets analyzed met all of the minimum nutrient concentrations. While short-term feeding may not be of concern for an individual patient, clinicians should be aware of potential nutritional limitations when feeding enteral diets to ill or injured cats.

Radiography and fluoroscopy in the 3 birds demonstrated variable degrees of gastric abnormalities, suggesting the presence of foreign material or stricture-like defects. Upper gastrointestinal rigid endoscopy by ingluviotomy revealed foreign bodies that were removed endoscopically. Minor postoperative complications were pulmonary congestion or mild aspiration and cardiac arrhythmia, both of which resolved, and no serious deleterious effects were associated with endoscopy in the short or long term. Endoscopy is recommended for examination and removal of foreign bodies from the upper gastrointestinal tract because it is less invasive and traumatic than traditional surgical approaches.

It can result from primary intestinal disease (e.g., parasitism, various inflammatory disorders, infectious problems, neoplasia), disorders of the liver or pancreas that affect normal intestinal digestive and absorptive processes, and a number of other factors or conditions that adversely affect intestinal function in some way (e.g., dietary indiscretion, adverse food reactions, drugs [e.g., antibiotics], systemic disorders including renal disease, hyperthyroidism). Diarrhea is often classified according to location (small or large intestinal in origin), mechanism(s) of diarrhea (osmotic decreased solute absorption, secretory hypersecretion of ions, exudative increased permeability, and abnormal motility), and etiology.

Aspiration of acidic, alkaline, or ingesta-containing gastric contents can cause serious morbidity and mortality. Clinicians must be aware of conditions and clinical situations in which there is increased risk of aspiration. The most important aspect of the mitigation of the pneumonic complications of aspiration is prevention.
