[Nonspecific ulcer of the colon: a report on 12 endoscopically diagnosed cases]

Report on 12 patients with nonspecific ulcers of the colon diagnosed by colonscopy and biopsy. In 10 patients the course was favorable with conservative management. In 2 patients the symptoms were aggravated; in both patients this was due to a penetrating malignant tumour diagnosed at laparotomy a few weeks later. It is proposed that nonspecific ulcers of the colon should be managed conservatively. Further investigations and laparotomy are indicated only when symptoms progress.
