[Endoscopic removal of foreign bodies and intraoperative endoscopy (author's transl)].

Foreign bodies of the upper GIT are regularly extracted with endoscopes, provided, that they have neither left the pylorus, changed their form, nor perforated the wall. Endoscopic extraction is recommended when safe and spontaneous discharge is uncertain. Impacted rectal foreign bodies usually need proctologic or abdominal surgery. Intraoperative endoscopy should be limited to those organs that are not attainable by preoperative inspection like cholangioscopy and peroral jejunoileoscopy.
