Echo guided percutaneous transhepatic cholangiography with puncture transducer.

Conventional percutaneous transhepatic cholangiography (PTC) has some disadvantages because it is customarily performed blindly. If the bile duct is made visible, these disadvantages are eliminated. The biliary tree, if dilated, can be clearly delineated by ultrasound technique. By combining the B-mode examination of the biliary tract with the ultrasonic puncture transducer, percutaneous transhepatic cholangiography was performed successfully in 16 examinations on 12 patients. PTC needle could be inserted directly into the lumen of the bile duct without appreciable difficulty. The echo guided PTC was found to be an easier, safer, and more reliable method than the conventional blind technique.

A multiclinic double-blind trial of pyridinolcarbamate and inositol niacinate in ischemic ulcer due to chronic arterial occlusion.

A double-blind multiclinic trial compared the efficacies of pyridinolcarbamate and inositol niacinate in the patients with the ischemic ulcer due to chronic arterial occlusion. A thrice-daily dose of 1.5 g of pyridinolcarbamate or 1.2 g of inositol niacinate was given at random to the patients during cold seasons, and the effectiveness of treatment was assessed mainly on the basis of the clinical course of the ischemic ulcer and the rest pain. The patients were classified into 4- and 6-week groups. Beneficial results were recorded in 16 of 32 cases (50.0%) of the 4-week pyridinolcarbamate group, and in 24 of 42 cases (57.1%) of the 4-week inositol niacinate group. In the 6-week group favorable results were observed in 54 of 79 cases (68.4%) on pyridinolcarbamate, and in 36 of 74 cases (48.6%) on inositol niacinate. Although sympathectomy is currently indicated for these ischemic lesions, long-term treatment with pyridinolcarbamate is recommended on the basis of the finding that the 6-week treatment appears superior to the 4-week treatment and also to the 6-week treatment with inositiol niacinate.
