Vitamin A absorption test was performed in 15 patients after hepatic portoenterostomy (1 to 7 years old); eleven patients were jaundice free (T. Bil.< 2.0mg/dl), four patients were jaundiced (T. Bil.> 2.0mg/dl). In patients without jaundice, plasma vitamin A levels were 56.4±26.5μg/dl at fasting and showed a rise to about six time the fasting level on average during the 4 to 6 hours following administration of a test dose of 7,500u/kg retinol palmitate. In patients with jaundice, plasma vitamin A levels were 21.4±5.8μg/dl and vitamin A absorption test showed lower absorption curves. These results suggest that vitamin A absorption is disturbed in patients with jaundice whereas patients without jaundice showed almost normal absorption.
