Abstract

The innervations of the large intestine is responsible for it peristalsis and contractibility. Investigations of the enteric nervous system in many colon diseases have revealed changes in this structure. No study has been carried out on morphological changes of the enteric nervous system in the human large intestine with carcinoma. The aim of this study was to investigate potential changes in the structure of the enteric neurons in patients with sigmoid and rectal cancer. Material for the study was obtained from patients undergoing operations due to carcinoma of the sigmoid colon and rectum. Microscopic observation of the cancerous tumor of the human large intestine revealed changes in the enteric nervous system innervating this part of the gastrointestinal tract. In the region of the enteric plexuses located close to the tumour, disruption of their correct placement and structure was observed. The changes also consisted of the disappearance of neurons and nerve fibers forming these plexuses. In the solid cancerous tumour, elements of the enteric nervous system were not present. Destruction of the enteric nervous system in the course of carcinoma of the large intestine may cause disruption of proper intestinal function and may be responsible for part of symptoms which the patients suffer.
