[Clinical use of autologous frozen blood in the surgery of three esophageal cancer patients].
Autologous frozen blood transfusion (AFBT) has advantages both of autologous and frozen blood transfusion. In AFBT there are no remarkable adverse effects which often emerge after usual heterologous blood transfusion. As a rule, four hundred milliliters of blood were drawn twice from patients and reserved as autologous frozen blood (AFB) preoperatively. It is supposed that radical operation of esophageal cancer using only AFB is difficult to perform because of various kinds of preoperative risks. In this paper three cases of radical esophageal cancer operations, in which only AFBT were used are reported. Pre- and postoperative liver functions were uneventful. RBC counts, Hb and Hct dropped after drawing blood and did not recover until the day of operation. Postoperatively, they deteriorated further but recovered to initial values without any specific treatment within 5 months after operation. Pre- and postoperative PaO2 values of AFBT were not different from those of the usual blood transfusion. Thus using only AFBT, esophageal cancer operations were performed without any disadvantageous effects.
