The present experimental study analyzed the spontaneous intestinal movements of proximal jejunum and distal ileum in rats, after ordered plication in ileum. Thirty-one albino rats were utilized, distributed into three groups submitted to the same experiment: group A - animals reoperated on 10th day after ordered ileal plication; group B - animals reoperated on 20th day; group C - animals reoperated on 60th day. Ordered plication of the ileum was performed in four intestinal segments, each of length 2 cm. In the reoperation, a sectioning procedure was performed, removing the plicated intestinal segments with the pre-plication jejunal segment and post-plication ileal segment, as a single piece. Two chemographs were utilized for simultaneous recording of the spontaneous intestinal waves. Analysis was done of frequencies of types I, II and III physiological waves in the proximal jejunal and distal ileal segments of groups A, B and C, separately and together. The statistical study was performed using the non-parametric methods of Kruskal-Wallis, Friedman and Wilcoxon. The results of the present experiment concluded that ordered partial ileal plication does not interfere in spontaneous intestinal movements represented by types I, II and III waves in the pre-plication jejunal segment and in the post-plication ileal segment after two months of the operation.
