Abstract
We report our own experience of the use of “PANENDOSCOPE for upper G.I. tracts”, model UGI-RA, whose feature is forward viewing small outside diameter (O.D.) with insertion section of biopsy forceps, manufactured by FUJI PHOTO OPTICAL CO., LTD. The newly developed fiber scope has 8 mm O.D. of flexible section, in which 2 mm diameter of biopsy forceps channel is incorporated. The specifications of the scope are as follows;
•Field of view : 105°
•Observation range : 2 mm to 120 mm
•Bending capability : UP 200°, DOWN 90°
•Total length : 1270 mm
•Working length : 1110 mm
The fiberscope is a type which adds a forceps channel to the model UGI-RU which was previously reported by Okada and others (Gastroenterological Endoscopy 25 (5) 802, 1983) . Although O. D. of its flexible section increases to 8 mm from 6.4 mm of UGI-RU, insertion is done as easily as UGI-RU. According to patients, no difference in pain has been felt compared with similar models during examinations. Image quality was the same as the one acquired by UGI-RU. Some increase in the 0. D. remains. However, additional functions of the model such as suction capability and sampling of tissue by biopsy make it suitable for use in quick examination for screening and part of close examination. We have carried out 60 cases of observation and treatment by using this model. Observation of esophagus, stomach, and duodenal bulb was centered and it provided satisfactory image quality. Limitation in biopsy forceps movement of Up and Down may give an operator slight inconveniences during examin-ations. As a result, we appraise the model UGI-RA a useful equipment for initial screening and group examinations.
