title: Gastrointestinal pathology in South America.
abstract: Non-neoplastic gastrointestinal disease in South America is largely related to environmental conditions. Parasitic disorders, including Chagas' disease with megacolon, predominate in endemic regions. Common enteritides of various etiologie are frequent, whereas appendicits, diverticulosis of the colon, ulcerative colitis and Crohn's disease are extremely rare. There was no appendicitis in native Indians of Paraguay.
