We carried out measurement of gastric lesions in the inner surface of the stomach with a measuring system, which is composed of a stereo endoscope and a personal computer. Basically, the length on a flat board from 10 mm to 50 mm was measured by varying the distance between the lens and the board and the angles of the endoscope at first. The error of the measurement was less than 8.5%. Secondly, ten physicians of our clinic attempted the measurement of the pasted discs on the inner wall of a stomach model with the endoscope. The average measurement error and the average time required for endoscopy became more better using the newly developed system than a measuring rod. Clinically, we measured the length of stomach lesion and of normal mucosa in six patients and compared the values obtained with those of resected fresh specimens. The length of stomach lesions could be measured more accurately than that of normal mucosa of stomach. From our observations, it can be said that this system is as available as the basic examination procedures in use at present and worth using in clinical procedure for it's high reliability.
我们使用由立体内窥镜和个人计算机组成的测量系统对胃内表面的胃部病变进行了测量。首先，通过改变镜头与平板之间的距离以及内窥镜的角度，测量平板上10毫米至50毫米的长度。测量误差小于8.5%。其次，我们诊所的十名医生尝试用内窥镜测量胃模型内壁上粘贴的圆盘。与测量杆相比，使用新开发的系统时，平均测量误差和内窥镜检查所需的平均时间有了更大改善。临床上，我们测量了6例患者胃部病变和正常黏膜的长度，并将所得值与切除的新鲜标本的值进行了比较。胃部病变的长度比胃正常黏膜的长度能更准确地测量。从我们的观察来看，可以说该系统与目前使用的基本检查程序一样有用，因其高可靠性而值得在临床程序中使用。
