Ileal stenosis
Ileal stenosis This patient had a history of Colitis in Crohn´s disease. In a double contrast enteroclysis a severe stenosis of the terminal ileum is suspected. Since all surrounding intestine shows a normal mucosal pattern phasic contractions are also considered. The stenosis remains unchanged during the course of the examination. Six months later ileus develops. The stenosis is confirmed intraoperatively and cleared by stricturoplasty.
