Evaluation of Preoperative Percutaneous Cholangiography in Long Term Biliary Carriers of Typhoid and Paratyphoid

During one year period of 1973, 15 cases of long term biliary carriers of typhoid and peratyphoid underwent surgical treatment of biliary tracts, in all of which the gallstones were observed. To get the evidence of the stones as many and clearly as possible, all cases received either one of the following two techniques of percutaneous cholangiography immediately before the operations. 1. Percutaneous cholecysto-cholangiography. Guided by duodenal sweep, gas shadow of the colon, and if obtained the gallbladder contour by orally or intravenously applied cholecystography and positive stone shadow under the fluoroscopy, the puncture was done from abdominal anterior wall below the right costal margin or from 7th or 8th ICS of the right thorax to the gall bladder and injected the contrast medium to get the picture of gallbladder and biliary tracts. 2. Percutaneous transhepatic cholangiography Intrahepatic bile duct was punctured through the right side of the thorax to get visualization of the bile ducts and gall bladder. The puctures were succeeded in 13 cases out of 15 and X-ray and operative diagnosis were consistent in them. In two unsucceeded cases who had gallbladder stones, there were technical failures owing to their too much obesity.
