Percutaneous cholecystostomy is regarded as a new method of treatment in patients with acute cholecystitis, especially patients with empyema who are considered unsuitable for cholecystectomy. In recent 2 years, authors performed percutaneous cholecystostomy for drainage purpose in 10 patients with poor surgical candidate. Under the guidance of real time ultrasound or fluoroscope, transhepatic access route for gallbladder intervention were chosen in all cases. successful decompression were obtained in 7 cases (70%; 6 patients with acute cholecystitis had decompression of gallbladder and 1 patient with common bile duct stone had biliary decompression. In three patient with cholecystitis, who had severe liver cirrhosis (N=1) or sepsis (N=2) as underlying condition, gallbladder drainage was not effective. Neither bile peritonitis nor hypotension occurred in any of these 10 cases. Percutaneous cholecystostomy has proved to be safe and effective treatment for patients with gallbladd r disease who are poor surgical candiate.

The classical roentgenographic features of tuberculosis of the spine (narrowing of the intervertebral disc, collapse of the vertebral bodies, with or without the shadow of a cold abscess) presents as specific picture of the actual pathological process. However the diagnosis of tuberculosis is not positive unless confirmed by biopsy, or the finding of the tubercle bacillus. 151 cases of spinal tuberculosis, proved at Seoul National University Hospital during the periods from June 1969 through June 1975, were studied and analysed. The result were as follows: 1. The ratio of male to female was 1.1:1. The age preference was under 10 years old (28%). 2. The most frequent site of involvement of the spinal tuberculosis was thoracic spine (38%), the next was lumbar (30%). 3. The incidence of lytic type is 56%, mixed type in 36%, and sclerotic type in 5%, respectively. 4. Ventral type wedging or collapse of vertebral body, is more predominant in younger age group and intervertebral art cular type in older age. 5. The incidences of typical radiologic finding were narrowings of intervertebral space (93%), collapse of vertebral body (74%), and cold abscess (52%), respectively.

The study was to evaluate the normal variations of abdominial aorta and its major branches in Koreans. Using a total of 363 abdominal angiograms and selective organ angiograpms, normal variation of aorta and its major branches including level of aortic bifurcation and of origin of major branches, multiplicity of renal arteries and variations of celiac trunk ewer observed and analyzed. The results are as follows ; 1. The celiac trunk usually arises form aorta at the level between middle 1/3 of 12 th thoracic vertebra and upper 1/3 of 1st lumbar vertebra, most frequently at the level of the lower 1/3 of 12 th thoracic vertebra. 2. The superior mesenteric artery usually arises form aorta at the level between disc space of 12 th thoracic vertebra and middle 1/3 of 1st lumbar vertebra, most frequently at the level of upper 1.3 of 1st lumbar vertebra. 3. The both renal arteries usually arise form aorta at the level between middle 1/3 of 1st lumber vertebra and disc space of 1st lu bar vertebra, most frequently at the level of lower 1/3 1st lumbar vertebra. The frequently of the multiple renal artery was 19% and right than left side in 56%. 4. The level of aortic bifurcation is usually at the level between middle 1/3 of 4th lumbar vertebra and disc space of 4th lumbar vertebra, most frequently at the level of lower 1/3 of 4th lumbar vertebra. 5. The classical normal pattern of celiac and hepatic arteries was shown in 74.6%, Anomalous origin of common heaptic artery was seen in 1.9%, anomalous origin of right hepatic artery in 5.8% and accessory right hepatic artery in 2.9% . Anomalous origin of splenic artery was in 1.3% and originated from superior mesenteric artery.

Purpose : To evaluate the role of bile duct obstuction in the development of atrophy of the liver, using ananimal model. Materials and Methods : Seven rabbits were divided into two groups : group 1(n=5), in which therewas selective bile duct ligation, and group 2(n=2), which underwent a sham operation. Each group was evaluatedusing CT for changes in hepatic volume after selective bile duct ligation or a sham operation. In group I, thediameter of dilated bile duct was measured 2, 4, 8, 12 and 16 weeks after bile duct ligation, while gross andhistologic change were evaluated in all cases. Results : In group 1, bile duct dilatation was seen on CT two weeksafter selective bile duct ligation, and did not change significantly during follow-up. In four of five cases, CTrevealed no evidence of significant atrophy of the involved segment. Pathologic specimens, however, revealeddilatation of the bile duct, periductal fibrosis, infiltration of chronic inflammatory cells, and periportalfibrosis. One of five cases showed segmental liver atrophy after selective bile duct ligation. In addion to theabove pathologic findings, there was obstruction of the portal vein by foreign body reaction. In group 2, noevidence of dilated bile duct or liver atrophy was revealed by CT or pathologic specimen after a sham operation.Conclusion : During long-term follow-up of 16 weeks, obstruction of the bile duct did not play a major role in thedevelopment of lobar atrophy in the rabbit.

Two patients with clinical and biochemical evidences of islet cell hyperfunction underwent percutaneous transhepatic portal and pancreatic vein catheterization and hormone assays. Local step-ups of insulin level in the protal venous system, found in two patients with insulinoma, corresponded to tumor sites at surgery. One patient had single insulinoma and the other had malignant insulinoma and liver metastasis. Percutaneous transhepatic protal and pancreatic vein catheterization with measurement of radioimmunoactive insulin concentration is a safe and reliable method, and may play an important role in the localization of adenoma in patients with hyperinsulinism.

Chest CT is the most useful modality in the diagnosis of primary lung cancer, particularly in patients with recurrent pneumonia which are resistant to antibiotic therapy and in high risk age groups for cancer. The purpose of this examination is to assess the usefulness of CT in pneumonic types of lung cancer. The authors retrospectively analyzed 15 histologically proven cases of pneumonic type lung cancer, which had no evidence of primary lung mass, mediastinal lymphadenopathy or other metastatic lesion on plain chest radiography. On CT scan, a primary lung mass was identified in 13 patients(87%), bronchial obstruction was identified in 12 patients(80%), and metastatic foci was found in the bone(one patient), liver(one patient), and spleen(one patient). In Conclusion, CT scan is a useful method to detect the mediastinal lymphadenopathy or pulmonary mass and also should be the initial radiolographic procedure for diagnosis of lung cancer in patients with recurrent pneumonia on imple chest radiography.

Purpose : To evaluate the air contamination of the gelfoam in the angio-intervention room. Materials andMethods : After exposing four groups of gelfoam(group A1 : gelfoam fragment, group A2 : gelfoam fragment+ saline +contrast media, group B1 : gelfoam powder, group B2 : gelfoam powder + saline + contrast media) to air in theangio-intervention room, we inoculated gelfoam in each group to 30 agar plates each at every fifteen minutes forone hour with aseptic cotton buds. Cultivating them in the incubator for one day, we evaluated the growth ofbacteria or fungus. Results : Out of 480 inoculated agar plates, the growth of coagulase(-) staphylococci wasvisible in 14 ; in group A1, two at 30 minutes, three at 45 minutes, and four at 60 minutes ; in group A2, one at45 minutes and two at 60 minutes ; in group B1 and B2, one each at 45 minutes. The stastical analysis on bacterialcontamination according to time sequence and group revealed no significance(p〉0.05). Conclusions : If gelfoam isexposed to room air for less than 30 minutes, it is possible to reduce contamination by air-borne bacteria. Sincecoagulase-negative Staphylococci resistant to commonly used antibiotics, it is ideal to reduce exposure of gelfoamto room air for less than 30 minutes.
