Approximately 80% of children afflicted with Hirschsprung disease will have aganglionosis confined to the rectum and rectosigmoid. The principles of operation for Hirschsprung disease are to remove the aganglionic section of the rectum and sigmoid and to perform a coloanal anastomosis in a portion of the colon with biopsy-proven ganglion cells present. In order to define the point of resection and pull-through, biopsies must be obtained. Often a clear transition from spastic, narrow distal bowel to the often thickened, dilated colon can be visualized (Figure 1).
