Simultaneous endoscopic and radiologic examination of the colon.

The selective radiologic visualization of pathologic ileocolonoscopic findings using contrast medium offers various advantages over endoscopy or radiologic evaluation performed alone. It allows one to combine a macroscopic biopsy with the radiologic examination and documentation procedure. The technique proves useful to document benign and malignant stenoses and tumors of the colon, diverticular disease, and mucosal abnormalities in long-standing ulcerative colitis and Crohn's disease, and to visualize fistulae, the appendix, or terminal ileum. Up to now, 146 patients have been examined without complication.
