The purpose of this paper is to show the changes of the intestinal motility following the end-to-end anastomosis. Dogs were used as experimental animals. The recordings of spike burst and slow potential were made from the intestinal walls of anastomosed site.
(1) When anastomosis was performed between duodenum and Treiz lig., the gradient of basic electrical rhythm (BER) of intestine remained unchanged.
(2) Anastomosis in the lower level of Treiz lig. induced the marked fall of BER of anal part compared with that of oral part of anastomosis. In this condition, BER of anal part was coincided with that of terminal ileum. This fall of BER in anal part persisted for about two months after the operation.
(3) During the first postoperative week, the marked suppression of spike burst generation was observed in both oral and anal parts, although the suppression was stronger in anal part than oral part.
(4) The increasing of intraluminal pressure was effective to recover from the suppression of spike burst generation.
These findings were suggestive of existence of higher background excitability in oral part of anastomosis in early postoperative days.
