title: Idiopathic megacolon.
abstract: This leading article refers to the paper by Meier-Ruge WA, Muller-Lobeck H, Stoss F, Bruder E. The pathogenesis of idiopathic megacolon. Eur J Gastroenterol Hepatol 2006; 18:1209-1215. We apologise to all concerned for the dissociation between the two papers, which was due to an administrative error. The pathogenesis of idiopathic megacolon is still unclear. Besides abnormalities of the enteric nervous system, alterations in the function of intestinal smooth muscle cells and connective tissue elements might play an important role. A permanent extension of the bowel diameter without concrete hints to its aetiology is termed idiopathic megacolon. Evidence exists that idiopathic megacolon comprises a heterogeneous group of conditions characterized by alterations of the enteric nervous system, smooth muscle cells and/or connective tissue. Innovative molecular techniques are needed to get further insights into the pathogenesis of these intestinal motility disorders.
