12. (2) The aganglionic LAS of patients with HD was more strongly innervated by cholinergic nerves than the normal IAS (p<0.05).

13. It could be shown that neurogenic megacolon in adults is not only caused by aganglionosis but also by non-aganglionic innervation disorders.

14. This finding can be explained by the high tonus of the rectum oral to the aganglionic bowel which was left after rectal myectomy.

15. In contrast to the early manifestation of aganglionosis, non-aganglionic or acquired alterations to the intramural nerve plexus often remain unrecognised up to adulthood.

16. The absence of myenteric ganglia in Hirschsprung’s disease results in massively increased parasympathetic activity with abundant acetylcholine release and pseudo-obstruction in the aganglionic segment.

17. Since the musculature at the oesophageal entrance is arranged in a screw-like fashion the aganglionic zone lies obliquely to the longitudinal axis of the oesophagus.
