title: [Endoscopic study of the small intestine].
abstract: The author summarises the possibilities of small bowel endoscopy. In case of haemorrhage of unknown origin, enteroscopy may be helpful. Sonde type fiber- or video-enteroscopes can be used. This procedure is time-consuming and needs an experienced team. In case of life-threatening bleeding intraoperative enteroscopy is recommended. "Push" enteroscopy is the best, rapid method in the diagnostics of suspected diffuse intestinal diseases or circumscript lesions of the proximal small bowel. Adult or pediatric colonoscopies or jejunoscopes are available for this investigation. Endoscopic biopsy specimens are suitable for histological examination and for enzyme assay as well. Aspiration of jejunal fluid for bacteriological culture is a way for revealing of bacterial overgrowth. The author emphasises the importance of the deep duodenoscopy made by an upper panendoscope in the diagnostics of villous atrophy.
