[Intestinal triplication--a case report of embryogenesis of tubular and cystic small intestine duplication].

Case report of a triplication of the ileum that has not been described so far in this form, with tubular as well as additional cystic duplication within the first malformation, in a boy of 3 years of age. Due to recurrent massive bleeding per anum and the impossibility of separation, resection of the entire involved intestine was performed. The cause of bleeding was found to be a 10 to 8 mm ulcer within the dystopic gastric mucosa that extended into the submucosa. The theories of pathogenesis are discussed, implying that there is no uniform genesis of this disorder. The clinical pattern, diagnosis and therapy are that of the duplication.
