RESUMEN
OBJECTIVE: To determine the prognosis in horses with cecocolic or cecocecal intussusception. DESIGN: Retrospective study. ANIMALS: 30 horses with cecocolic intussusception or cecocecal intussusception. PROCEDURE: Information on history, physical examination findings, and laboratory values was summarized from the medical records. Laboratory data included results of hematologic examination, serum biochemical analysis, and peritoneal fluid color, total nucleated cell count, and total protein concentration. A one-year follow-up via the telephone was used to determine long-term survival. RESULTS: Horses ranged from 7 months to 30 years old, but 63% were < or = 3 years. Standardbred horses were significantly overrepresented. Twenty-six horses had acute-to-subacute disease, and 4 had a chronic wasting disease. Cecal intussusceptions were suspected on the basis of finding a mass on abdominal palpation per rectum (14 of 24 horses) and positive ultrasonographic findings (2 of 3 horses). Thirteen horses with colic for > 1 day had scant, soft feces. Six horses died or were euthanatized without undergoing surgery, and 24 were treated surgically. Six of the latter horses were euthanatized during surgery because of peritonitis, rupture of the cecum, and irreducible intussusception. All 4 horses with a chronic disease were euthanatized because of irreversible changes in the cecum. Of the 18 horses allowed to recover from surgery, 15 survived long-term. Surgical treatments were reduction, with or without partial typhlectomy (6 horses), partial typhlectomy through a colotomy and reduction (6), reduction through a colotomy and partial typhlectomy (3), partial typhlectomy for a cecocecal intussusception (1) and an ileocolostomy (2). CLINICAL IMPLICATIONS: Cecal intussusception has a good prognosis with surgical correction without delay. Reduction through colotomy has a high success rate. Bypass by ileocolostomy should be used as a last resort.

An experiment with ileostomized adult roosters was conducted to determine the ileal digestibility and urinary excretion of D-xylose and L-arabinose. As a reference, D-glucose was included in the experiment. The sugars were tested at graded dietary levels of 2.5, 5.0, 7.5, and 10.0%. Mean ileal digestibility of D-glucose and D-xylose was nearly 100%. Ileal digestibility of L-arabinose decreased linearly (P less than .05) with increasing dose level. The corresponding ileal digestibilities for L-arabinose at dietary levels of 2.5, 5.0, 7.5, and 10.0% were 95.5, 93.6, 80.3, and 74.6%. Both pentose sugars were partly excreted in the urine. The extent of this urinary excretion in percentage of intake increased linearly (P less than .05) as the dietary level increased. In roosters fed the 2.5% D-xylose diet, 7.2% of the D-xylose consumed appeared in the urine. This level increased to 20.2% when roosters were fed a diet containing 10.0% D-xylose. Corresponding values for L-arabinose at these dietary inclusion levels were 8.7 and 16.6%.

Described in this paper are ileocecal cannulation and ileorectostomy, two methods used for quantitative collection of chyme in the context of protein assessment on the basis of prececally absorbable amino acids. Reference is made to the manufacture of new, flexible intestinal cannulas of biocompatible material and to the surgical approaches in connection with either method. Determination of prececal digestibility of crude nutrients and absorption of amino acids in three rations fed to pigs with ileorectal anastomoses and ileocecal cannulas gave identical data or fair agreement with the extension of two amino acids. The conclusion was drawn that data recorded by means of the two methods can be used in the preparation of tabulated values.

O objetivo foi avaliar a funcionalidade da adaptaçao deum esfincter artificial originalmente descrito por Schiller a um reservatorio ileal, no intuito de se obter um reservatorio ileal que associasse facilidade na sua execuçao a uma eficiente continencia. Foram operados 16 caes, nos quais adaptamos esta modalidade de esfincter a um reservatorio ileal em "J". Pelos resultados observados, observamos que esta tecnica conferiu continencia aos reservatorios no periodo analisado, nao tendo sido observadas perdas entre as entubaçoes, apesar das sobrevidas curtas em funçao da grande morbidade das ileostomias em caes.
