D-Lactic acidosis 25 years after bariatric surgery due to Salmonella enteritidis

D-lactic acidosis is a rare complication that occurs in patients with short bowel syndrome due to surgical intestine resection for treatment of obesity. The clinical presentation is characterized by neurologic symptoms and high anion gap metabolic acidosis. The incidence of this syndrome is unknown, probably because of misdiagnosis and sometimes symptoms may be incorrectly attributed to other causes. Therapy is based on low carbohydrate diet, sodium bicarbonate intravenous, rehydratation, antiobiotics, and probiotics that only produce L-lactate. In the case we describe, D-lactic acidosis encephalopathy occurred 25 y after bypass jejunoileal, due to Salmonella enteriditis infection. (C) 2012 Elsevier Inc. All rights reserved
