[Wernicke's encephalopathy developed several years after total gastrectomy. Report of 2 cases].
We present here 2 cases of Wernicke's encephalopathy developed several years after total gastrectomy. Case 1. A 48-year-old male developed impaired recent memory and unsteady gait. He had undergone total gastrectomy for advanced gastric cancer 5 years previously; he had been on tegafur regimen for 4 and a half years. He had had 630 ml of beer every day for 6 months until admission. On admission, there were bilateral abducens palsy, horizontal nystagmus, gait ataxia, and areflexia. Cranial MR imaging was unremarkable. After intravenous infusion of vitamin B1, the patient improved. Case 2. A 56-year-old male developed exertional dyspnea, memory loss, and unsteady gait. He had undergone total gastrectomy for a large submucosal tumor 4 years previously; he had had 300-500 ml of sake almost every day thereafter. Examination revealed bilateral abducens palsy, severe gait ataxia, and areflexia. Chest CT scans demonstrated moderate amount of pericardial effusion. Blood vitamin B1 level was abnormally low. After administration of vitamin B1, he improved. Both patients had had alcoholic drinks; laboratory findings demonstrated no liver dysfunction. Drinking alcohol, even in relatively small quantities, could precipitate the development of Wernicke's encephalopathy in gastrectomized individuals. Our 2 cases stress the importance of supplementary vitamin B1 administration after total gastrectomy.
