Angiographic evaluation of the abnormal endoscopic pancreatogram.

Out of 1,269 pancreatograms, 122 were abnormal. Angiography was performed in these patients. Fifty-five were found to have pancreatic carcinoma. In the remaining 67 patients a false positive angiographic diagnosis of either chronic pancreatitis or pancreatic cancer was made in 11%. In one patient a hemangioma was diagnosed as a pancreatic cyst. The remaining 58 patients all had normal pancreatic angiograms in spite of gross ductal abnormality on endoscopic retrograde cholangiopancreatography (ERCP). All these patients were followed for an average of 19 months and showed no clinical evidence of pancreatic disease. It is suggested that angiography should be considered a complementary examination to ERCP and is particularly useful to exclude carcinoma when the pancreatogram is abnormal.

[Transhepatic biliary drainage for obstructive jaundice (author's transl)].

Sixty-five patients with obstructive jaundice out of a total of 71 patients, were treated successfully by PTCD. The markedly elevated total bilirubin and alkaline phosphatase in the serum were reduced significantly and the general condition of the patient improved rapidly. On the other hand, severe obstructive jaundice which had persisted for several weeks was not amenable to treatment in this way. Occlusion of the extrahepatic bile ducts by tumour was treated by internal PTCD; this provided satisfactory flow of bile into the duodenum for at least six months. PTCD is simpler for the patient than surgery and is therefore the method of choice in obstructive jaundice. Finally, PTCD can be used for the introduction of antibiotics for the treatment of suppurative cholangitis or liver abscesses. This rapidly leads to reduction in fever and absorption of the abscesses.

Comparison of barium swallow and left gastric angiography in the diagnosis of esophageal varices, with special reference to the management of variceal bleeding.

Seventy-five patients with portal hypertension and esophageal varices were studied by means of barium swallow and selective left gastric angiography. The relative merits and limitations of these techniques in demonstrating the presence, extent, and severity of the varices are discussed, with reference to the selection of patients for prophylactic transection of the esophagus to prevent bleeding from the varices.

Experience with percutaneous transhepatic cholangiography using the Japanese needle.

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.

The diagnosis of the small resectable pancreatic carcinoma.

ERCP and angiography are essential for the accurate diagnosis of pancreatic carcinoma. ERCP is of value in detecting a pancreatic tumour and is the only examination which makes it possible to detect a small pancreatic carcinoma. Angiography is indispensable for the evaluation of the extent and size of the carcinoma, for prediction of resectability, and for differentiation between pancreatitis and carcinoma. Thirty-one out of 32 pancreatic carcinomas (96%) were correctly diagnosed pre-operatively by the use of a combination of the two examinations. Ten of them (31%) were resectable, and of these six measured less than 2 cm in diameter.
