[Combined gastroduodenoscopy and suction biopsy of the small intestine].

We are reporting on a simple method for performing gastro-duodenoscopy and biopsy of the small intestine on one course of examination. The biopsy probe for the small intestine carries a looped thread located behind the biopsy cartridge. This loop is grabbed by the biopsy forceps of the gastroduodenoscope. After both instruments have been inserted simultaneously, the biopsy probe may be pushed through the pylorous visibly and without any effort. This is followed by the gastro-bulbuscopy, if necessary with biopsy, and thereupon followed by the biopsy of the small intestine. To date we have examined 15 patients using this method. The examination was delayed in 2 patients only who had a markedly scarred bulb. We consider this method suitable for routine diagnostics since time is saved for both the examiner and the patient, since a two-fold insertion of instruments may be avoided, since the exposure to radiation is reduced, and since it is possible to obtain complete endoscopic findings with biopsy.
