Faecal stasis in proctocolitis.

Six cases of faecal stasis in active proctocolitis are reported. In each case the left colon was severely diseased but the right colon was unaffected. X-ray studies showed retention of barium in the right colon for as long as five weeks. In two patients subacute intestinal obstruction developed and in three patients constipation was a major symptom during the active phase of colitis.
