Polyneuropathy, Myocardial Dysfunction and Pericardial Effusion Following Duodenal Switch.

Duodenal Switch procedure is a type of bariatric surgery that was reserved for severely morbid obese people. Patients undergoing this procedure are at high risk for nutrient deficiencies. In this report we present a case of a patient who had developed polyneuropathy, generalized muscle weakness, Wernicke encephalopathy, myocardial dysfunction and pericardial effusion six years following this operation. He was treated by multivitamins and trace elements with a complete resolution of all of these disturbances. The patient was fully rehabilitated.
