The image resolution of fiberoptic and video endoscopy was compared in a series of patients with early gastric cancer. Eighteen patients were divided into two groups. One group of patients (n = 9) was evaluated with fiberoptic endoscopy while the second group (n = 9) was evaluated using video endoscopy. The extent of cancer invasion, with special attention to size, shape and type of the lesions, was evaluated in each patient. Attempts were also made to identify the proximal and distal limits of tumor invasion and the endoscopic and postoperative findings were compared. Endoscopic delineation of lesions was possible in more patients undergoing video endoscopy compared to fiberoptic endoscopy. Video endoscopy gave better endoscopic images for determination of the limits and of the size of cancer invasion. Indigo dye spraying enhanced the accuracy rates in both groups of patients. The results of this study suggest that video endoscopy may be more useful than fiberoptic endoscopy in the evaluation of minimal mucosal changes of the gastrointestinal tract. We believe that video endoscopy may have a useful role in the gastrointestinal endoscopy if the problem of expense, which is its main drawback, can be solved.
在一系列早期胃癌患者中比较了纤维内镜和视频内镜的图像分辨率。18例患者被分为两组。一组患者（n = 9）接受纤维内镜检查，而另一组（n = 9）接受视频内镜检查。评估了每位患者的癌症浸润范围，特别关注病变的大小、形状和类型。还试图确定肿瘤浸润的近端和远端界限，并比较内镜检查结果和术后结果。与纤维内镜检查相比，更多接受视频内镜检查的患者能够在内镜下清晰显示病变。视频内镜在确定癌症浸润的界限和大小时能提供更好的内镜图像。靛胭脂喷洒提高了两组患者的准确率。本研究结果表明，在评估胃肠道最小黏膜变化方面，视频内镜可能比纤维内镜更有用。我们认为，如果视频内镜作为主要缺点的费用问题能够得到解决，那么它在胃肠内镜检查中可能会发挥有益作用。
