In summary, severe hyperchloremic acidosis developed in two patients as a late complication after jejunoileal bypass for morbid obesity. This acidosis was associated with episodes of dizziness, ataxia, headache, weakness, confusion and transient loss of consciousness. Recognition of this symptom complex in the patient with a jejunoileal bypass should suggest metabolic acidosis as a complication of this surgical procedure. Bicarbonate replacement provided prompt, but temporary, improvement in the symptoms and the acidosis. Revision of the intestinal bypass was required for correction. Special studies to rule out renal tubular acidosis were performed and definitely excluded the kidney as a source of the acidosis.

Accumulation of D-lactate after gastrointestinal surgery, particularly jejuno-ileal bypass, is an uncommon and often misdiagnosed clinical disturbance. The syndrome may be complicated by dizziness, ataxia, confusion, headache, memory loss, and aggressive behavior. Serum chemistries are often deceptive because the anion gap is frequently normal in spite of severe metabolic acidosis. Moreover, the urine anion gap may be positive, incorrectly suggesting a defect in renal net acid excretion. Indeed, the combination of a normal anion gap metabolic acidosis and positive urine anion gap may erroneously suggest a diagnosis of renal tubular acidosis. Importantly, all reported cases of D-lactic acidosis secondary to bypass surgery have been encountered within 5 to 10 years following the surgery. Here we present an unusual case of D-lactic acidosis (complicated by encephalopathy) presenting 23 years after a jejuno-ileal bypass procedure. The patient was initially diagnosed with a drug intoxication secondary to benzodiazepines. Ultimately, the diagnosis of D-lactate encephalopathy was established after challenging the patient with a carbohydrate load. Thus, administration of 40 kcal/kg over 16 hours reproduced the clinical syndrome and was accompanied by a marked increment in serum and urine D-lactate concentration. The patient had sustained resolution of her symptoms after treatment with oral vancomycin.
