title: Vitamin B12 absorption in total gastrectomy. Study with (57Co) B12 and radioimmunoassay.
abstract: Vitamin B12 absorption and real amount of circulating cyanocobalamin were determined by Thurangh Schilling's test and radioimmunoassay respectively, in 28 patients undergone total gastrectomy. The methods are described and the results discussed, in relation to the parameters under consideration, that is: age, sex, pathology of lesion, time elapsed from surgery, and type of reconstruction of intestinal continuity.
