Abstract

The main pancreatic duct was studied endoscopically by inserting an ultra-thin pancreatoscope into the normal papilla of Vater. Recently, we developed a new pancreatoscope system and improved the image, the durability, and the ease of use. A special video converter was connected to the head of the pancreatoscope. The sequential electronic endoscope images were observed on a TV monitor. We performed examinations with this new system in 52 cases (8 with pancreatic cancer, 19 with chronic pancreatitis and 25 normal cases). We studied the brightness, color and quality of the images on 35-mm film and on videotape. As a result, it has become clear that the images obtained with this system are much better than those obtained by the conventional method. Although further improvement in the ability to angulate the endoscope is necessary, this new pancreatoscope system should help diagnose diseases of the pancreas.

摘要

通过将超薄胰管镜插入正常的 Vater 乳头对主胰管进行内镜研究。最近，我们开发了一种新的胰管镜系统，并改善了图像、耐用性和易用性。一个特殊的视频转换器连接到胰管镜的头部。在电视监视器上观察连续的电子内镜图像。我们用这个新系统对52例患者进行了检查（8例胰腺癌、19例慢性胰腺炎和25例正常病例）。我们在35毫米胶片和录像带上研究了图像的亮度、颜色和质量。结果表明，该系统获得的图像比传统方法获得的图像要好得多。尽管内镜的角度调节能力仍需进一步改进，但这种新的胰管镜系统应有助于胰腺疾病的诊断。
