To two patients suffering from intractable upper abdominal pain associated with recurrent carcinomatosis following previous gastrectcmy, 10 per cent saline solution was administered through an indwelling epidural (T 7-8) catheter. The results are as follows: 1) The method effectively relieved the pain in both patients. 2) The durations of pain relief were variable. It is noteworthy, however, that the method is. remarkably effective in relieving intractable pain associated with incurable malignancies. 3) The pain accompanying saline injection could be modified by prior administration of xylocaine through the same catheter. 4) The method was simple without complications, hence ambulatory application was possible.
