 The significance of the GTF type gastrocamera in light of the marked increase of the panendoscope today lies in the fact that it is a side-viewing fiberscope and high quality photographs can be obtained by the camera situated at the tip. The panendoscope can be used for endoscopy of all of the upper GI tract whereas the GTF type is used strictly for the stomach. The GTF type is a gastrocamera with a fiberscope attached and thus, it can be called a gastrocamera in its broad sense. The recent GTF adopts a method of illumination using the lamp tip as well as a light guide. These consist of the S-type with which biopsy cannot be performed and the B-type with which biopsy is possible.

 Next to the high observational capacity of the GTF type, it makes possible the taking of outstanding photographs using the gastrocamera and diagnosis is made by a detailed reading of these pictures. At times, lesions left undetected during observation are discovered later with this method and therefore, the reading of GTF photographs is extremely vital.

 There have been recent progress in improving panendoscopic pictures, however generally, emphasis is laid on diagnosis during observation. Due to the fact that the GTF type is a side-viewing fiberscope, one must abide by the basic rule to confirm that the patients possess no diseases such as in the esophagus and cardia which make this method of examination contraindicated to certain patients.

 Because panendoscopy is easy to perform, it is gradually replacing the x-ray and GTF method. However, the GTF should be used in order to make a more detailed diagonsis as well as follow-up.
