CLASSIFICATION

Intestinal obstruction may be classified into two types: /uni25CF Dynamic , in which peristalsis is working against a mechanical obstruction. It may occur in an acute or a chronic form ( Figure 78.1 ). /uni25CF Adynamic , in which there is no mechanical obstruction; peristalsis is absent or inadequate (e.g. paralytic ileus or pseudo-obstruction).
