[Radiographic examination of the colon in Denmark. A questionnaire study].

Technical and practical routines for barium enema X-ray examinations in Denmark were investigated using of questionnaire to all hospitals and clinics. Most departments use a routine double contrast technique. In spite of the limited size of the country there are great variations in preparation and technique. Only a few departments used laxatives and increased fluid intake for one to three days. All departments send written instructions to out-patients but only a few have written instructions for in-patients. The time interval from referral to examination is short for in-patients but varies for out-patients.
