[Functional and morphological studies on diverticulosis of the large bowel]

In comparison to the normal colon, longitudinal and circular musculature in diverticular disease (DD) was investigated--regarding motility and morphology--and a comparative measurement between musculature and mucosa was also performed with following results: 1. Only the tenia in DD revealed a spastically contracted muscle. 2. There was a ribbon formation due to contraction only in tenias of DD, although there was hypertrophy in both muscle groups. 3. The longitudinal muscle in DD was found to be shortened.
