Fifty-four cases of minute esophageal cancer (1 cm or less in the greatest dimension) were collected and analyzed. Of these 67% were mucosal cancer and 28% were submucosal cancer. Prognosis was anticipated to be good as there was only one case of lymph node metastasis and three of vascular invasion. A lesion of 1 cm can be regarded as curable regardless of its depth of invasion. The endoscopic approach with use of a dye staining technique is useful for detection of or screening for minute esophageal cancer.
We have adapted a new, high-performance magnifying fibercolonoscope (FCS-ML II) developed by Machida Industries, for clinical use. We have observed the remission process of ulcerative colitis with this new instrument and have compared our findings with those obtained by clinical examination, X-ray, ordinary gastroscope, and histologic examination of biopsy specimens. Our results show that the findings of magnifying fiber-colonoscopy correspond to those obtained with biopsy and histology, indicating that this new instrument promises to be a highly effective tool for the accurate assessment of the degree of remission of ulcerative colitis.
Abstract. Percutaneous transhepatic cholangiography using a very thin needle has been performed in 885 patients with a variety of underlying hepatic, biliary, and pancreatic disorders. The procedure was successful in 99% of the patients with dilated intrahepatic bile ducts and in 85% of those with non-dilated ducts. Complications which required surgical intervention occurred only in two cases (0.2%). In patients with obstructive jaundice, external bile drainage was performed immediately after visualization of the bile duct. Percutaneous transhepatic cholangiography is an extremely useful and safe method for investigating disorders of the biliary tract, for localizing the cause of obstructive jaundice, and for reducing the degree of jaundice and improving the general status of patients with obstructive jaundice.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
