[The debut of Crohn's disease as a gastrocolic fistula].

The case of a 66-year-old women admitted for the study of chronic diarrhea and an important deterioration in her general state is reported. Following the study undertaken the presence of a gastrocolic fistula was observed without clarifying the nature of the same thereby leading to surgical treatment. Anatomopathologic analysis confirmed the presence of a gastrocolic fistula in relation to Crohn's disease. The origin of these fistulas is usually neoplastic and the presentation as a complication of an inflammatory disease is very infrequent.
