[Study of the quality of colonoscopies]

The quality of colonoscopy in Denmark has been questioned over the last few years. In order to explore any differences between international standards and local department performance a prospective study of the quality of colonoscopies was made.

Over 5 months 342 consecutive colonoscopies were examined at Randers Hospital, surgical department K. Success rate, patient characteristics, time usage, endoscopic procedures, charge and usage of x-ray were monitored.

Patient characteristics were comparable with other studies. The rate of success for cecal intubation was 93% of all colonoscopies. Mean time for cecal intubation was 12 minutes and 17 seconds for experienced doctors while the group of trainees used 17 minutes and 54 seconds. Experienced doctors performed 80% of all colonoscopies. X-ray was used in 5 colonoscopies.

The usage of time and the rate of success in cecal intubation reach the quality standards of comparable international studies. In addition, usage of x-ray seems irrelevant in achieving cecal intubation. The distribution of colonoscopies between experienced doctors and trainees lowers opportunities for education of trainees.
