Use of propofol for anesthesia in cats with primary hepatic lipidosis: 44 cases (1995-2004).

OBJECTIVE-To determine morbidity and fatalities in cats with hepatic lipidosis that received propofol to facilitate placement of a feeding tube. STUDY DESIGN-Retrospective case series. ANIMALS-44 Cats with presumed primary hepatic lipidosis anesthetized for placement of a feeding tube. PROCEDURES-Medical records from January 1995 through December 2004 were reviewed to identify cats that matched the inclusion criteria (histologic confirmation of hepatic lipidosis, anesthetized for placement of feeding tube, complete intensive care unit [ICU] records, and recorded outcome). Data extracted included age, body weight, sex, anesthetic drugs, drug dosages, type of feeding tube, duration of anesthesia, number of hours in ICU, administration of blood products, and survival until discharge from ICU. RESULTS-44 Cats (21 females and 23 males) were included in the analysis. Age range was 3 to 15 years (median, 8 years), and body weight ranged from 1.8 to 9.0 kg (4.0 to 19.8 lb), with a median of 4.8 kg (10.6 lb). Twenty-seven cats were administered propofol. There was no significant association between the use of propofol or the dosage of propofol and any risk factor, need for blood products, number of hours in the ICU, or survival. There was no significant difference between cats that received propofol and cats that did not receive propofol with regard to interval until discharge from the ICU. CONCLUSIONS AND CLINICAL RELEVANCE-The use of propofol did not increase morbidity or fatalities in cats with primary hepatic lipidosis. Thus, propofol can be used in these cats for placement of a feeding tube.

Gallbladder mucocoele and concurrent hepatic lipidosis in a cat.

A 3-year-old Domestic Shorthair cat was presented with weight loss, anorexia and icterus. Feline hepatic lipidosis and gallbladder mucocoele were diagnosed; this is the first report of gallbladder mucocoele in the cat. The case was managed successfully with cholecystojejunostomy, gastrostomy tube placement and tube feeding for 3 months. The cat has survived over the long term with minimal complications.

[Lipid island (xanthelasma) of the duodenal mucosa--a rarely found diagnosis and differential diagnosis]. / Die Lipidinsel (Xanthelasma) der Duodenalschleimhaut--ein seltener Befund Diagnose und Differentialdiagnose.

A case report ist given on a 54-year-old patient with the so called lipid island (xanthelasma) in the duodenal mucosa. Xanthelasmas are very rarely located in the duodenal mucosa. The diagnosis and differential diagnosis of this entity are reported. The relevance of histochemistry and immunohistochemistry for differentiation of signet ring carcinoma cells in the mucosa is discussed.

[Ultrastructural findings in secondary lipoidosis of the cornea]. / Ultrastrukturelle Befunde bei sekundärer Lipoidose der Hornhaut.

A patient suffering from a progressive keratopathy which could not be identified clinically underwent penetrating keratoplasty. Light microscopy showed cholesterol deposits in deep stromal regions. Further ultrastructural investigations confirmed these findings and, in addition, fibrous long spacing collagen was found in that region; this represents a new factor in the possible pathogenesis of corneal lipid degenerations.

[Problems of the stone-free gallbladder, a report on 276 cholecystectomies]. / Zur Problematik der steinfreien Gallenblase, ein Bericht über 276 Cholezystektomien.

Different kinds of disease of the gallbladder without stones are demonstrated. The indication for cholecystectomy is given by anamnesis, radiological findings and the exact exploration of the adjoining organs. There is made a difference between absolute and relative indications. Among 6,311 cholecystectomies there are 276 gallbladders without stones (4.37%). The results of postoperative controls are reported, more than 76% of the patients are absolutely free, 16% are relatively free of complaints.

[Cholesteatosis of gallbladder (author's transl)]. / Cholesteatose der Gallenblase. Eine vergleichende Untersuchung chirurgischer und sezierter Fälle

741 cholecystektomies were examined for cholesterosis. In 92% gallstones were present and in 8% there were no stones. Cholesterosis of the gallbladder was found in 0,9% of 4417 autopsies. It was combined with gallstones in 25% and in 75% it was not. There was no difference concerning the clinical symptoms between cholesterosis with and without stones in the surgical patients. Cholesterosis without stone presented the same picture as gallstones. In the autopsy material however no typical symptoms could be found indicating either cholesterosis with gallstones or without. In the histological examination 80,5% of the cases with gallstones in the surgical and autopsy group had inflammatory changes of the gallbladder wall whereas only 22% of the cases with stoneless cholesterosis showed these alterations. Fibrosis of the gallbladder wall however was found in 86,1% in cases with cholesterosis without stones and in 88% in cases with stones. From these findings the conclusion is made that cholesterosis is no well defined disease. Clinical symptoms seem to appear only when other factors, such as stones, inflammation or functional disturbances probably because of fibrosis of the wall, become manifest in addition.
