Pseudoaneurysm due to chronic pancreatitis is uncommon, but it can cause recurrent and massive hemorrhage. Because of high morbidity and mortality associated with the pseudoaneurysm, early detection and treatment is essential. Surgical ligation or resection of the aneurysm has a high mortality and therefore, transcatheter embolization is preferably carried out. We report a case in which gastroduodenal artery pseudoaneurysm caused by chronic pancreatitis was successfully treated by transcatheter embolization using Gelfoam and Gianturco spring coils.

We evaluated the role of retroperitoneal laparoscopic ureterolithotomy (RPLU) for upper ureter stones. Between February 1998 and July 2004, 12 patients (10 men and 2 women) underwent RPLU for upper ureter stones (mean size 18.1 mm, range 10-25). RPLU was carried out in 5 patients as a salvage treatment after failed shock wave lithotripsy (SWL) (3) and both of failed SWL and ureteroscopy (URS) (2), and in 7 patients as primary treatment for large impacted stones. Total 6 of 12 cases were converted to open surgery. The reason of open conversion was failure of locating ureter due to severe adhesion in 5 cases and vascular injury in 1 case. In 6 successful cases, mean operation time, mean estimated blood loss, and mean postoperative hospital stay were respectively 109 min (90-120 min), 50 mL (10-100 mL), 4.6 days (2-7 days). There was no serious postoperative complication except for one patient who showed delayed urinary leakage but was cured with conservative management. Our experience suggested that RPLU was not easy to perform simply because it was indicated mainly in ureter stones with severe adhesion or after failed SWL and/or URS. Nevertheless, it can be considered as a primary procedure before open ureterolithotomy.

We report a case of histopathologically confirmed hepatic angiosarcoma. A 29-year old patient was admitted with fever and palpable tender mass in the right upper abdomen. On ultrasonography, a large, well circumscribed mixed echoic mass was seen in the right lobe of the liver. On CT scan, irregular enhancement was seen mainly in the peripheral portion of the mass ; the central portion was not enhanced. The mass showed low signal intensity on T1W1, and high signal intensity on T2WI. Peripheral nodular enhancement was noted on Gd-enhanced MR images; In the peripheral portion of the mass,

PURPOSE: The purposes of this study were to evaluate the plain radiologic findings of the childhood intussusception and to evaluate the role of plain abdominal films in predicting the success of air or barium reduction. SUBJECTS AND METHODS: We retrospectively reviewed 140 cases with the diagnosis of intussusception in children. The radiological signs that included soft tissue mass, dilatation of small bowel suggesting obstruction, crescent sign, and target sign were evaluated in terms of frequency. The relationship between radiological findings and outcome of reduction was analyzed. The site of soft tissue mass or crescent sign seen on plain radiographs was correlated with the position of the apex of the intussusceptum seen at the beginning of barium enema. The degree of dilated small bowel was evaluated by calculating the proportion of air-filled small bowel occupying peritoneal cavity and measuring the maximal diameter of dilated bowel lumen. The radiological finding for small bowel obstruction is determined by observation of the degree of small bowel dilatation and/or air-fulid levels. RESULTS: Ninety-two cases out of 140 showed one or more radiographic signs. Two most common signs were soft tissue mass and small bowel obstruction. The success rate of air or barium reduction was significantly lower in patients with most severe degree of dilatation of small bowel and/or more than 7 air-fulid levels on erect view. The suspected location of intussusception on plain radiographs correlated well with the true location of intussusception seen in the first few seconds of barium reduction. CONCLUSION: Plain abdominal radiography is useful in the diagnosis of intussusception and provides helpful informations for the reduction procedure as well as for the exclusion of the contraindications such as bowel perforation.

PURPOSE: To evaluate useful findings and diagnostic value of TI-201 thyroid scan in differentiating benign from malignant nodules. MATERIAL AND METHOD: We studied 77 cold thyroid nodules proven histologically(27 malignat and 50 benign). Early (5--15rain) and delayed images(3--5hours) were obtained after intravenous injection of thallium 201. In these nodules, we retrospectively analyzed the degree of TI-201 uptake in early and delayed images, histopathologic type, size, and presence or absence of cystic change in the sonograms of 22 malignant nodules. RESULTS: Useful finding for diagnosis of malignant nodules was strong uptake of TI-201 in early and delayed images(specificity:98%, sensitivity:63%, positive predictive value:94.4%). Useful finding for benign nodules was no uptake of TI-201 in delayed image(specificity :88.9%, sensitivity :68%, positive predictive value :91.9%). The accuracy of TI-201 thyroid scan in differentiating benign from malignant nodules was 66.2%. The nodules with strong TI-201 uptake in early image and low TI-201 uptake in delayed image were malignant in 29.4%. Cystic changes were found in 40% of malignant nodules with atypical TI-201 uptake. TI-201 thyroid scan showed high specificity in follicutar neoplasm and adenomatous goiter in which differentiation of benignancy and malignancy is difficult with only cytologic examination. CONCLUSION: We consider that TI-201 thyroid scan is valuable in differentiating benign from malignant nodules and when combined with fine needle aspiration and ultrasound examination, it will enable more accurate differential diagnosis between benign and malignant thyroid nodules.

PURPOSE: To measure the normal size of the styloid process using 3D (three-dimensional) reconstruction CT. MATERIALS AND METHODS: We retrospectively analyzed 3D reconstruction images obtained after coronal and axial CT scanning of the temporal bone or neck of 115 patients. The length and shape of both sides of the styloid process, the location of its tip, and calcification of the stylohyoid ligament were retrospectively analysed. RESULTS: The mean length of the styloid process was 26.6 (+/-7.9)mm on the right side, and 26.4(+/-8.3)mm on the left, a statistically insignificant difference (p=0.694). Its mean length was 26.2 (+/-8.5)mm in men and 26.7 (+/-7.2)mm in women, a statically in significant difference (p=0.733). As for variation with age, mean length tended to increase until the third decade, but not beyond. Segmental type (104/230, 45.2%) and fragmental type (73/230, 31.7%) were more commonly seen in shape of styloid process, and tapering tip of styloid process (156/230, 67.9%) is more commonly seen than clubbing tip of it (74/230, 32.1%). The process was angulated in six cases (2.6%); its tip was more frequently located between the internal and external carotid artery (211 cases, 91.7%) than more medially (19 cases, 8.3%). In the former location, the length of the process was 26.2(+/- 7.2)mm, and in the latter, 37.0(+/-6.0)mm. The difference was statistically significant (p=0.000). Calcification had occurred in 33 cases (14.3%). CONCLUSION: The length of a normal styloid process was 18-32 mm. There were no statistically significant differences between its two sides, or between the sexes. Length tended to increase until the third decade, but not beyond. Predominantly the tip was located between the internal and external carotid artery, though the process was longer when its tip was located medially.

The causes of the chylothorax can be classified to the congenital cases, such as the atresia of thoracic duct and thoracic duct-pleura fistula, and the acquired ones, such as thoracic surgery, trauma, malignant disease, venous thrombosis, infection and so on. We experienced a case of left chylothorax in a 10-year-old girl with a lymphangiomatosis of left thorax extending from axillar to buttock. She first received the two weeks of conservative management, which was unsuccessful to subside the chylothorax. Then she was taken the partial pleurectomy and chemical pleurodesis under the thoracoscopy as a surgical intervention, but this is also insufficient to reduce the chylous effusion. Finally she received 10 times of radiotherapy on left thorax, then the chylothorax is controlled completely.

This study was conducted to evaluate the accuracy of the official death registry in rural area. The base data used for the study was 379 deaths registered during the period of 1993 and 1994 in 4 rural townships of Chonnam Province. The interview survey for cause-of-death was performed on the next of kin and/or neighbor. Additional medical informations were collected from hospitals and medical insurance associations for the purpose of verification. The underlying cause-of-death of 278 cases presumed by the survey was compared to the cause on official death registry. There was a prominent disagreement of cause-of-death between the survey data and the registry data(agreement rate: 38.9~44.6%%, according to disease classification method). These results may be caused by extremely low rates of physicians' certification, which were mostly confined to the poisoning and injury. Symptoms, signs, and ill defined conditions on death registry could be classified into circulatory disease(32.3%), neoplasm(21.2%), digestive disease(7.l%), injury and poisoning(7.l%) and so on. These results suggest that careful attention and verification be required on utilization of death registry data in rural area.

PURPOSE: The purpose of this study was to determine the efficacy of sonography in the evaluation of normal pseudocapsular morphology and the detection of complications after total hip arthroplasty. MATERIALS AND METHODS: Between Janvary 1997 and June 2000, 47 patients [35 men and 12 women aged 24 to 84 (mean, 61) years] using real-time linear-array, convex US units with 3.5-MHz and 10-MHz transducers. Normal capsular morphology in 30 with total hip replacements, who had been asymptomatic for at least one year, was studied, and the prosthetic joint infection demonstrated in six of 17 who had experienced was confirmed at surgery or by US-guided aspiration. RESULTS: Sonograms indicated that a normal pseudocapsule lay straight over the neck of the prosthesis or was slightly convex toward the neck, and that the mean bone-to-pseudocapsule distance was 2.9 mm. However, in the 11 symptomatic patients in whom no evidence of infection was revealed by cultures, th mean distance was 4.7 mm; in the remaining six patients, whose joints were infected (a condition strongly suggested by the presence of extracapsular fluid), the mean distance was 5.5 mm, with no significant difference between the two groups. CONCLUSION: Sonography can be used to evaluate normal caspular morphology after total hip replacement and to diagnose infection around hip prostheses. In all patients in whom sonography revealed the presence of extra-articular fiuid, infection had occurred.

PURPOSE: Percutaneous cholecystostomy (PC) using a pig-tail catheter is indicated for high risk acute cholecystitis. However, this procedure is time consuming, expensive and requires radiological equipment. This study compared PC using a pig-tail catheter with central venous catheterization set. METHODS: From January 1992 to June 2003, 44 patients underwent PC without a malignancy or a combined hepato- biliary-pancreatic disease were selected. A retrospective study was performed on the time interval to procedure, cost, complications and therapeutic results of the central venous catheter group (A, 15) and the pig-tail catheter group (B, 29) RESULTS: The time interval was 1.8 days in group A, 3.52 in group B (p=0.002). The cost was 188,684 won in group A, 327,814 won in group B. There were 4 complications in group A (2 leakage, 1 dislodgment, 1 malfunction) while 5 in group B (2 dislodgement, 1 sepsis, 2 malfunction). Although PC, 2 in group A and 5 in group B were discharged hopelessly or died due to the progression of the underlying disease. Twenty-two patients underwent a delayed cholecystectomy with 7 patients in group A (3 laparoscopy, 4 open) and 15 in group B (6 laparoscopy, 8 open, 1 conversion to open). The complication rate was slightly high in group A but there were no statistical significance, no clinical problems and no difference in the mortality rate and surgical method. CONCLUSION: In high risk acute cholecystitis, PC using central venous catheter is easy, economic, effective and performed at early stage in the emergency room by medical doctors or surgeons.
