ENDOSCOPY 3 gastroscopes duodenoscopes colonoscopes




GASTROINTESTINAL FIBERSCOPES
(INCLUDING GASTRoSCOPES,
DUODENOSCOPES AND COLONOSCOPES)
Based on the angle of view, there are three types of instruments:
1.      Forward or oblique (foreoblique) viewing for examination and biopsy This is suitable for examining the esophagus, most of the stomach and the upper part of the duodenum.
2.      Side or lateral viewing for examination, biopsy and operative procedures in the duodenum This is needed when full examination of esophagus, stomach, duodenum and biliary system is required. This includes the fundus of the stomach and the duodenal bulb.
3.      Forward viewing with two channels for complex operative procedures This is generally larger in diameter than the previous two and has suitable dimension channels incorpo­rated for operating instruments. A wide range of procedures can be undertaken.
         All three types of instruments can be obtained from several manufacturers.
