  • Abstract
  • Look Inside

 We are of the opinion that hypotonic duodenography is the method of choice in the diagnosis of lesions in the duodenum, and in this paper is introduced our procedure. Also is decribed a guide wire for facilitating the introduction of duodenal probe together with the gist of probe insertion utilizing the wire.

 The essentials of x-ray diagnosis of lesions in the duodenum are also presented after dividing them into functional abnormalities, congenital ones, diverticulum, neoplasms, inflammation and others.

 As was proposed by Dr.Hayashi of the Department of Pathology in our College of Medicine, the papillary region is defined as that conical area within the duodenal lumen where choledochopancreatic duct is surrounded with the sphincter of Oddi. Hayashi assumed that papillary cancer mostly arises from the bile duct within the duodenal wall, but from the viewpoint of roentgenologic diagnosis we believe that papillary cancer should be considered as a lesion of the duodenum.

 In x-ray diagnosis of cancer and other lesions of the papillary region, simultaneous coemployment of hypotonic duodenography and percutaneous transhepatic cholangiography is most effective.

 A case of carcinoma in the minor papillaiy illustrated as well, with some comments on the necessity in future of many-sided investigations regarding the accesory papilla. Finally, some problems in dealing with duodenal lesions have been discussed.
