Chronic intussusception is a rare but completely correctable cause of failure to thrive in infants and children. The presenting features differ from acute intussusception. We present the case of a 16 month old boy presenting with a three week history of anorexia, diarrhoea, and weight loss with subsequent delayed diagnosis.

Of a series of ninety-six young male Syrian Golden hamsters, 13% developed lethargy, anorexia, diarrhoea and colocolic intussusception when their diet was changed from a basal laboratory-grade rodent chow to a nutritionally complete semi-purified diet. Histologically, the colon of the hamsters with intussusception had markedly reduced mucus production. Plasma levels of gastric inhibitory polypeptide (GIP) were reduced 80% (P less than 0.01) but peptide tyrosine/tyrosine and enteroglucagon in plasma were increased 290 and 526% respectively in hamsters with intussusception. Variations in dietary fatty acid composition had no effect but intussusception was not observed after changing the dietary carbohydrate from sucrose to starch.

The immunosuppressive activities of a newly discovered macrolide extracted from Streptomyces tsukubaensis, FK506, were examined using 38 renal allografts in the beagle dog. The median survival time was 15.5 days in dogs without treatment, 61 days with a dose of 0.08 mg/kg/day and 176 days with a dose of 0.16 mg/kg/day of intramuscularly administered FK506. Prolongation of survival was statistically significant when compared with controls (P = 0.02, 0.0044, respectively). None of 6 recipient dogs receiving the agent at a dose of 0.16 mg/kg/day encountered rejection during the treatment course. Three of them survived over 200 days. Oral administration of FK506 at a dose of 0.32 mg/kg/day did not prolong the median survival time (20.5 days) compared with the placebo treated control (16.5 days), but oral treatment with 1.0 mg/kg/day resulted in all of the recipient dogs surviving over 130 days. Histological studies of 7 kidney graft biopsy specimens of the dogs surviving over 3 months revealed no cell infiltration or only some degree of reversible interstitial cell infiltration, but vascular and glomerular changes were not observed in any of the specimens. Irregularity of nuclear shape and cytoplasmic vacuolation of the pars recta of the proximal tubules were observed in one dog each. Liver biopsy specimens showed no consistent evidence of hepatocellular damage. Three dogs died of intussusception 2-3 weeks posttransplant. The dogs treated intramuscularly with 0.32 mg/kg/day suffered from anorexia. Two dogs receiving oral treatment at a dose of 1.0 mg/kg developed papilloma of the skin around day 60, but the tumors disappeared by day 120. We conclude that FK506 is a powerful immunosuppressant in the dog with tolerable side effects.

A 10-month-old Alsation dog with history of anorexia, diarrhoea, dehydration and vomition developed a double intussusception which affected the distal jejunum and proximal ileum. Necropsy revealed the intussusception to be swollen and congested with fibrinous adhesions between the intussusceptum and intussuscepiens. Two pieces of bone believed to be the inciting cause were found within the intussusceptum. Clostridium welchii and Clostridium bifermentans were isolated from the lesions.

Clinical examination of a ten month old Holstein heifer with a history of colic and anorexia revealed a distended viscus in the midline and a hard, sausage-shaped mass in the right lower posterior quadrant of the abdomen. At surgery, the mass was exteriorized and found to be an intussusception of the colon into the spiral colon. The intussusception was reduced by traction and the animal made an uneventful recovery.

A 21-month-old German shepherd crossbreed presented with a nine-month history of intermittent vomiting, anorexia and melaena interspersed with periods of clinical normality. Investigations suggested recurrent pancreatitis and the vomiting resolved with supportive therapy but recurred two weeks later. Abdominal radiographs revealed evidence of an intermittent abdominal mass which, on ultrasonography, had the typical appearance of an intussusception. At laparotomy, a gastroduodenal intussusception was found obstructing the pancreatic and bile duct outflows with perforation of the duodenal wall. The dog was euthanased. Postmortem examination and histology showed no obvious cause for the intussusception but confirmed pancreatic involvement. This is believed to be the first case of gastroduodenal intussusception reported in an animal.

Trichobezoars are accumulations of hair casts in the stomach associated with trichophagia. The typical patient is an adolescent female who presents with alopecia and an upper abdominal mass which on moving can cause intermittent gastric outlet obstruction. Only a minority of patients have severe psychiatric disorders. When hair strands extend from the main mass in the stomach, all along the small bowel and reaching the cecum, the condition is termed the Rapunzel syndrome. In about 5% of patients there are separate hair masses in the stomach. The clinical presentation includes abdominal pain, loss of appetite, weight-loss, vomiting, loose stools, pancreatitis, jaundice, anemia and hypoalbuminemia. These signs and symptoms raise the suspicion of malignancy. Complications of bezoars include ulcers, perforation of the bowel, obstruction and intussusception. Diagnosis can be established either by barium swallow or by CT scan. Ultrasound might suggest the diagnosis, but sonographic features are definitely not pathognomonic. Treatment is surgical, as endoscopic removal is usually unsuccessful. We present 2 children in whom trichobezoars were found.

Postmortem examination of a 3-year-old male Iranian native sheep with a history of anorexia and severe colic, revealed an intussusception of the small intestine, 30 cm proximal to the ileocaecal junction. Scattered hyperplastic lesions were present in the jejunal and ileal mucosa especially in intussuscipien. Microscopic examination of these lesions showed severe papillary hyperplasia of the epithelium associated with developmental stages of coccidia in the epithelial cells. An unusual type of intussusception and the presence of the proliferative nodular form of coccidiosis in the intestinal wall of intussuscipien suggested that coccidiosis could be considered as the possible cause of the problem.

Impaction of the gizzard was diagnosed in 33 1-to-4-wk-old lesser rhea (Pterocnemia pennata) raised on farms in Patagonia, Argentina. The birds showed anorexia, lethargy, constipation, dehydration, weight loss, and weakness. Necropsy revealed gizzard impaction by fibrous material, sand, rocks, and rubbish. Also, excess fibrous material was observed in the small intestine, and intussusception was found in one chick. Impaction of the gizzard observed in the present study was similar to that reported in other ratite species and confirmed that this disease can affect lesser rhea chicks raised in captivity. This disease affected 33 out of 41 (80%) dead lesser rhea chicks submitted to the Animal Health Unit of The National Institute of Agricultural Technology, Bariloche, Argentina, during the study period, so it can be a significant cause of mortality in farmed rheas in Argentina.

A 4-year-old Thoroughbred stallion was referred for signs of mild to moderate colic, anorexia, and decreased water intake of 3 weeks' duration. Ultrasonographic examination revealed an intussusception, the most common of which would be a cecal inversion or ileocecal intussusception. Surgical exploration identified an ileocecocolic intussusception with extension of the intussusceptum into the right ventral colon; however, the cause of the intussusception could not be identified. The intussusception could not be surgically corrected, and the horse was euthanatized. A side-to-side jejunocecostomy that had been performed previously was identified at necropsy. The ileal stump had intussuscepted into the right ventral colon and become hypertrophied, causing partial obstruction of the cecocolic orifice and clinical signs of colic. In horses requiring an ileocecal or jejunocecal anastomosis, the ileal stump may be left to slough within the cecum as part of the treatment for an irreducible ileocecal intussusception or intentionally inverted into the cecum when the ileal stump is necrotic and cannot be exteriorized and resected. Efforts should be made to minimize the size of the ileal stump to reduce the liklihood of intussusception.
