Summary
New instruments for dilatation of the upper gastrointestinal tract are described:
1. A hollow plastic bougie with an inside diameter of approximately 10 mm to allow
a 9 mm endoscope to pass. The diameter of this tube-like bougie increases in four
steps up to 16 mm.
2. A second-similar bougie employs a flexible bronchoscope for guidance of the bougie.
This system permits bougienage from 4 to 11.5 mm.
The system permits stepwise bougienage of stenoses using only two instruments. For
the first time complete endoscopic control of bougienage is possible.
Key words:
Bougienage - Bougie - Dilatation - Dilator - Therapeutic endoscopy
