Electrical activity was recorded from the stomach, duodenum, jejunum and ileum of 8 mongrel dogs which survived for more than two years after 90% massive bowel resections. Despite a considerable delay in gastric emptying time in the dogs with massive bowel resections, the electrogram revealed no substantial difference between the electrical activities of the stomach in normal dogs and the dogs with massive bowel resections. The basic electrical rhythm in the jejunum orad to the anastomotic line was 15-17 cycles/min., and in the ileum caudad to the anastomosis was 8-12 cycles/min. This evidence indicates that the gradient of the slow wave rhythm is maintained even for more than two years after jejunoileal anastomosis and the frequency of the slow wave of the residual digestive tracts generally tend to decrease in compensatory stage.
