A case of Meckel's bleeding diverticulum diagnosed by emergent arteriography is presented. Arteriography revealed an extravasation of contrast medium into the distal ileum and an abnormal ileal artery which passed to the antimesenteric border of the ileum. The diverticulum was demonstrated by double contrast study of the small intestine. The merits of emergent arteriography and other examinations for diagnosing Meckel's diverticulum are discussed.
Eighy cases with carcinoma of the pancreas were divided into 10 groups according to the location and size of the tumor. Drip infusion cholangiography, percutaneous transphepatic cholangiography, hypotonic duodenography and endoscopic retrograde cholangiopancreatography were employed for this classification. Comparison of cholangiopancreatograms (ERCP) with results of the biliary and pancreatic secretory function assessed by pancreozymin secretin test (PS test clarifies secretory capacity of the exocrine pancreas. But combination of ERCP and PS test with cytology is necessary for the correct diagnosis of the pancreatic cancer and it is hoped that the combination may excavate the disease in the early stage.
