Management of maple syrup urine disease in the peri-operative period.

Abstract Maple syrup urine disease (MSUD) has an incidence of 1:125,000 newborns in Ireland. Patients, when fasting, or in a catabolic state build up toxic metabolites leading to progressive neurological dysfunction. We describe the necessary peri-operative management of a patient with MSUD who developed symptomatic gallstones requiring a laparoscopic cholecystectomy.
