A rare complication of adjustable gastric banding: Wernicke's encephalopathy.

BACKGROUND

Wernicke's encephalopathy is an uncommon complication seen after morbid obesity surgery. Neurological and cardiac symptoms can occur. Early and adequate replacement of thiamin is crucial.

METHODS

A patient, who was operated by adjustable silicone gastric banding had severe vomiting 1 week after the operation. Physical examination showed no abnormalities except neurological signs consisting of ataxia, disorientation and diplopia. All radiological and biochemical parameters were in the normal range.

RESULT: After replacement of vitamin B1 (thiamin) intravenously 20 mg twice daily, all the neurological signs regressed day by day. Oral thiamin pills have been continued.

CONCLUSION

Wernicke's encephalopathy which occurs as a result of thiamin deficiency is a rare complication that has serious morbidity with rapidly progressing neurologic symptoms, and must be treated immediately. Surgeons who treat morbidly obese patients must follow the metabolic and nutritional status of the patient.
