There are few studies of changes in chemistry after this operation. Wernicke-Korsakoff encephalopathy was seen in two patients at 3 months after bypass surgery (1). In one patient megaloblastic anemia appeared 6 years after surgery (2). Serum vitamin B12was below normal in 26% of 69 patients (3). We are not aware of studies of vitamin B12absorption or of the effect of oral supplementation in patients who have had bypass surgery. After a low serum vitamin B12level was found in several patients, this study was done....References1. HAID R, GUTMANN L, and CROSBY T. Wernicke-Korsakoff encephalopathy after gastric plication.
