Treatment of idiopathic hepatic lipidosis in cats: 11 cases (1986-1987).

Idiopathic hepatic lipidosis was diagnosed in 11 cats. Cats were treated by delivery of balanced nutrients supplemented with L-carnitine via a surgically placed gastrostomy tube. Feeding through the gastrostomy tube was initiated in the hospital and was continued at home in all cats. The mean duration of gastrostomy tube feeding was 48 days (range, 22 to 98 days). Vomiting associated with feeding (3 cats) and localized cellulitis at the gastrostomy site (2 cats) were the most frequent complications. Vomiting was controlled by reducing the volume of food administered at each feeding or by administration of metoclopramide. Cellulitis was treated successfully by parenteral administration of antibiotics and local wound cleansing. Seven of 11 cats (65%) survived and have remained clinically healthy for 15 to 29 months (mean, 20 months) since diagnosis. The other 4 cats died of peritonitis (n = 1), pneumonia (n = 1), hepatic encephalopathy (n = 1), or cardiopulmonary arrest (n = 1) between 0 and 10 days after surgery.
