Abstract
The origin of anti-peristaltic discharge occured in the distal stomach of canine after transection followed by end-to-end anastomosis is uncertain. The purpose of this paper is investigate electromyographycally whether the mucosa of the distal stomach effects on occurence of anti-peristaltic discharge.
By appling lidocaine to the lumen of the distal stomach after transection followed by end-to-end anastomosis, the retardation of propagation velocity of normo-peristaltic discharge and the decrease of frequency of anti-peristaltic discharge were noted on the antrum.
On respect of frequency of anti-peristaltic discharge, the findings above were remarkable in the high appearant group (5 dogs; ≥80%) compared with low appearant group (2 dogs; ≤60%).
Conclusively, it was suggested that the occurrence of anti-peristaltic discharge was related to the enteric nervous system in the mucosa and/or submucosa.
