[Mucosal relief patterns in the colon (author's transl)].

Various types of mucosal relief patterns in the colon were classified on the basis of 270 double contrast examinations. Ten patterns were distinguished. In about 60% of examinations a normal pattern could be recognised, consisting of fine linear or reticular shadows. All other patterns depend on a substrate of morphological changes, which may result from surgical anastomoses, from stenoses or from inflammatory changes.
