Abstract
Motilities of the rectum, ileum, and ceca were examined in surgically prepared turkeys by using strain gauge transducers implanted on these sites after cecal ligation or colostomy. All birds were provided ad libitum access to feed and water throughout the study. Cecal ligation increased the frequency of small anti-peristaltic contractions in the proximal (P < .01) and distal (P < .05) rectum and the frequency of defecations (P < .05) compared with intact controls. Cecal ligation decreased the frequency of single contractions in the proximal ileum (P < .05) and that of all contractions in the distal ileum (P < .05), and ligation (P < .01) and colostomy (P < .05) increased the frequency of single contractions in the distal site. However, major and minor cecal contractions were not affected by colostomy in the proximal and distal cecum. The results suggest that the effects on contractile activities of the hindgut must be considered when interpreting responses to cecal ligation and colostomy.
