A teaching model for endorectal ultrasound-guided biopsy and drainage of pararectal tumors.

For determination of histology of small solid and microbiology of liquid pararectal tumors there is no other method than endorectal ultrasound-guided biopsy. Also for therapy of abscesses or seromas drainage application is possible. With this technique an operation may be prevented. In awareness of possible complications such as major injury of rectal wall, bleeding, persistent fistula and sepsis, teaching and training in this method is consequently necessary. For a training program a lifelike model of the rectum was developed. It has been used by 780 participants in 20 training courses organized by the Surgical Department of University Hospital Würzburg.
