In clinical centers in which colorectal surgery is carried out, stoma therapy units should be set up. The stoma therapist is the most important partner of the surgeon in providing pre- and postoperative care, and giving instruction and information to stoma patients and their relatives. For various reasons, this has been realized only insufficiently but has been implemented in some cases. It should, however, not be overlooked that further developments in stoma therapy have meanwhile had positive effects in other fields of surgery and nursing. Engaged stoma therapists have not only assisted surgeons in patient care but have also imparted new knowledge and shown competence in surgical therapy.
