Wernicke-Korsakoff disease with sensory-motor neuropathy was diagnosed in three out of a series of 1663 patients (0.18%), with onset 2, 3 and 5 months after biliopancreatic diversion. Precipitating factors were vomiting, minimal food intake, anorexia, rapid weight loss, and glucose-containing intravenous feeding. Recovery was partial in two and complete in one of the patients. In the early postop, prophylactic thiamine should be given to the patients with excessively limited eating capacity. Larger doses of thiamine should be instituted parenterally either in the case of suspected Wernicke-Korsakoff encephalopathy or before starting feeding for protein malnutrition.
