A total of 72 cases of internal biliary drainage procedure has been done percutaneously at Departement ofRadilogy, Seoul Natinal Universtiy Hospital for recent 4 and half years since August 1981. Five different types ofinternal drainage including endoprosthesis were applied to various conditions with different obstruction levels.The different method of procedure in each type of internal drainage was described and the results were analysed.1. Among the clinical diagnosis in 72 cases, carcinoma of bile duct was in 37 cases as the most frequent one. Thenext was pancreas head carcinoma in 16 cases, followed by metastatic carcinoma and other disease. 2. Type Iinternal drainage, classical internal and external type with distal end in duodenum, was applied in 43 cases asthe most comon one. Type II, modification of type I with distal end in CBD, was applied in 17 cases. Type III,endoprosthesis distal end into duodenum, was applied in 7 cases. Type IV, endoprosthesis just across theobstruction in bile duct, was applied in 2 cases, Type V, combined type of any internal drainage with externaldrainage, was applied in 3 cases. 3. According to various obstruction level, prefered type could be selected. Forproximal obstruction type II and IV were preferred and for distal obstruction type III was chosen. However, type Icould be applied in any situation. 4. Early complication occurred in 9 cases(12.5%). Clinical imporvement withdecrease in bilirubin level was observed 17 of 21 cases in which follow-up data was available over 2 months. 5.Though the experience with those 72 cases it is recommended that appropriate type of internal biliary drainageshould be selected according to prognosis, obstruction level and clinical findings of each patient.

In general, pelvic fracture carries higher mortality especially from motor veicle accident, we have retrospectively reviewed charts and radiographs of 185 patients in order to identify clinical fading, kinds of fracture, hemodynamic changes and associated injuries in patients with pelvic fractures. We attempted to classify pelvic fractures according Young classification. The following results were obtained; 1. On age and sex distribution, the pelvic fractures showed peak incidence between 2nd decade and 5th decade. Male was affected more frequently than female, the ratio being male to female, 2.6 to 1. 2. The mechamisn of injury was motor veicle accident in 155(83.8%), fall in 25(13.5%), others in 5(2.7%). 3. The associated injuries of pelvic fractures: extremity, thoracic, urinary system, intraperitoneal and head injury. 4. Of the 185 cases of the pelvic fractures, simple pelvic fractures are 101 cases(54.6%), lateral compression in 39(21.1%), anteroposterior compression in 18(9.7%), vertical shearing in 17(9.2%), mixed pattern in 10(5.4%). 5. Retroperitoneal hematoma and urinary tracts injuries were the most common associated in mixed pattern. 6. The incidence of hemodynamically unstable fractures were 19.8% in simple pelvic fracture but, as expected was higher in major pelvic ring disruptions except to acetabular fracture(52.4%). 7. Mortality rates were 5.9% in all pelvic fractures but 10.7% in major pelvic ring disruptions except to acetabular fractures. Prognostic factor in pelvic fractures were the amount of hemorrhage and associated injuries, therefore early diagnosis and managements are essential to reduce the mortality in pelvic fracture.

PURPOSE: We evaluated the importance of redistribution and 24 hour reinjection images in Tl-201 SPECT assessment of myocardial viability after acute myocardial infarction (AMI). MATERIALS AND METHODS: We performed dipyridamole stress-4 hour redistribution-24 hour reinjection Tl-201 SPECT in 43 patients with recent AMI (4-16 days). The myocardium was divided into 16 segments and perfusion grade was measured visually with 4 point score from 0 to 3 (absent uptake to normal uptake). A perfusion defect with stress score 2 was considered moderate. A defect was considered severe if the stress score was 0 or l (absent uptake or severe perfusion decrease). Moderate defect on stress image were considered viable and segments with severe defect were considered viable if they showed improvement of 1 score or more on redistribution or reinjection images. We compared the results of viability assess-ment in stress-redistribution and stress-reinjection images. RESULTS: On visual analysis, 344 of 688 segments (50%) had abnormal perfusion. Fifty two (15%) had moderate perfusion defects and 292 (85%) had severe perfusion defects on stress image. Of 292 severe stress defects, 53 were irreversible on redistribution and reversible on reinjection images, and 15 were reversible on redistribution and irreversible on reinjection images. Two hundred twenty four of 292 segments (76.7%) showed concordant results on stress-redistribution and stress-reinjection images. Therefore 24 hour reinjection image changed viability status from necrotic to viable in 53 segments of 292 severe stress defect (18%). However, myocardial viability was underestimated in only 5% (15/292) of severe defects by 24 hour reinjection. CONCLUSION: The 24 hour reinjection imaging is useful in the assessment of rnyocardial viability. It is more sensitive than 4 hour redistribution imaging. However, both redistribution and reinjection images are needed since they complement each other.
