| Abstract;Endoscopic injection sclerotherapy (EIS) is a very potent therapy for esophageal varices. However, its effect can only be achieved if done by an experienced endoscopist. It is difficult to ensure the placement of needle at varices for sufficient duration using the present therapeutic regimen. This is mainly due to an involuntary movement of the esophagus. As it is difficult to fix the endoscope at a variceal point, the needle may be fallen off even after entering into the varices. The aims of the study was to develop a new device for EIS so that the following purposes can be achieved; 1) proper maintenance of expanded visual field, 2) fixation of the endoscope at a vaiceal point. We modified a commercially-available straight type of transparent hood. We made a concave groove in this hood measuring 6.5 * 5.0 mm. This groove was adjusted to the endoscope so that it remains at 8 O'clock position. The groove of the hood remain aligned to the variceal point perfectly after the entry of the endoscope. Then 5% ethanolamine oleate iopamidol (EOI) was injected into the varix. EIS using this new device showed better therapeutic effects. For example, it was possible to introduce EOI in 89% of the supplying vessels by this new device compared to 30% by the previous method (p < 0.05). This new device is cheap, easy to use, has no complication and ensures better EIS. (author abst.) |
