D-Lactic Acidosis in a Patient with Jejunoileal Bypass

D-Lactic acidosis is an unique complication of jejunoileal bypass occurring because of alteration of colonic bacterial flora with selective proliferation of D-lactate-producing bacteria. The D-lactate accumulation in the serum is associated with encephalopathy, which responds to oral antibiotic drugs in most patients. Because gastroenterologists may encounter such patients for some time to come, we report a new case and review the literature.
