    Keywords : Irritable bowel syndrome; functional gastrointestinal disorder; immunohistochemistry; full-thickness biopsy; enteric nervous system; autoantibody; gastroenteritis; risk factor;

    Abstract : Aims of the thesis: To study new pathogenetic mechanisms in IBS; to find out if IBS is a neuromuscular disease affecting the small bowel; to study humoral factors in gut dysmotility associated with visceral neuropathy; and to study the natural history of post-infectious gastro-intestinal (GI) symptoms and risk factors for their development. Material and methods: In studies I and II, full-thickness jejunum biopsies from patients with severe IBS were investigated with immunohistochemistry. READ MORE
