Chiba-needle percutaneous cholangiography - a method without risk to the patient?
This critical review of PTC with the skinny needle was prompted by an unexpected complication - an intrahepatic hematoma. A negative PTC does not exclude the presence of dilated bile ducts. In the case of an obstructed biliary tree, bile leakage occurs in approximately 5%. Even after the Chiba needle or other techniques have become established, peritoneoscopy is still of value in the diagnosis of cholestasis. Thus, this method is not without some risk and optimistic reports should be judged with a certain reserve.

[Percutaneous transhepatic--versus endoscopic retrograde cholangiography in the differential diagnosis of cholestasis? (author's transl)].
Since the introduction of the Chiba needle the percutaneous transhepatic cholangiography (PTC) became an established method in the differential diagnosis of cholestasis beside the endoscopic retrograde cholangiography (ERC). From the clinical point of view it is sometimes difficult to decide which of these two techniques should be preferred. In case of absolute or relative contraindications or in case of failure of one of the two methods ERC and PTC can be used alternatively. In all other cases we feel that the PTC by means of the Chiba needle is superior because of easier technical handling and higher success rate. In addition PTC is less trying for the patients. However on the basis of our own experience is should be stressed, that even by using skinny needles there is danger of bile leakage, which necessitates an immediate surgical intervention in the presence of biliary obstruction.

Report on 3 cases of thrombosis of the axillary vein (Paget-von Schroetter-syndrome). In this relatively rare condition phlebography and early thrombolytic treatment are required.

[Septate gallbladder (author's transl)].
In 3,8% of 2,437 in-side patients, examined by x-rays, septs of the gallbladder, supposed to be congenital form variations, were found. There were no differences in sex distribution of the segmented organs and no recognizable correlation to increasing age. Usually, septations were found by accident without clinical relevance. In the proximal parts of the gallbladder located septs occasionally cause symptoms not to be differentiated from those of cholelithiasis. In these cases ectomize is indicated. Calculi are found to be more frequent in septate gallbladders than in unsegmented ones. Sex differences between concrement-bearing, septate gallbladders and unsegmented organs containing stones, were not observed. Likewise, there was no correlation of gallbladder-septs to other diseases, particularly to hepatitis.
