Expandable metallic stents(EMS) were implanted in 7 patients with malignant (4 cholangio- carcinnoma, 1 pancreatic cancer, 1 ampullary carcinoma and 1 lymph node metastasis) biliary stricutres and 17 patients with benign(13 intrahepatic strictures of primary intrahepatic stone patients, 2 postoperative stricutres, 1 ampullary stenosis followed by endoscopic sphineterotomy and 1 bilioenteric anastomosis) biliary stricutures. In the fifteen patients out of 17 patients with benign biliary stricture, relief of cholangitis, improvement of liver function or loss of pruritus was observed. But in the 2 patients with.biliary cirrhosis, no clinical improvement was noted. In the malignant strictures with cholangio-carcinoma, the occlusion of EMS occurred in 3 patients and the duration of stent patency was average 2 months in those patients.

A statistical analysis was performed with 623 intracranial tumor cases of which diagnoses were confirmed at the Department of Neurosurgery of Seoul National University Hospital from Sep. 1957 to Apr. 1981. The authors classified the intracranial tumors according to Russell and Rubinstein's classification. Epidermiological factors were analysed in general, and especially for the changes after CT introduction. The results were as follows: 1. Intracranial tumors were found most frequently in middle age group(20.9%), and the ratio of male to female was 1.8:1. 2. Among the intracranial tumors, gliomas were found most frequently(20.9%), and followed by granulomatous lesions(15.7%), pituitary adenomas(14.3%), Meningiomas(10.9%), vascular tumors(10.0%), schwannomas(5.1%). 3. The incidence of gliomas was less than that of otjer countries, especially glioblastoma multiforme. Pituitary adenomas occupied 14.3% of all intracranial tumors and as a single entity these were the highest incidence. Granulomatous lesions occupied 15.7% of all intracranial tumors. 4. Intracranial tumors occurred more frequently in supratentorial region. The most frequent location was wellar and parasellar regions(19.9%), and followed by frontal(17.2%), cerebellar(14.4%), parietal(14.0%), temporal region(9.5%). 5. Gliomas are the most frequent tumors irrespective of age group and in children then comes granulomatous lesions, medulloblastomas, vascular tumors and in adults then comes pituitary adenomas, granulomatous lesions, meningiomas in that order. 6. Since the advent of CT scan, the detection rate of intracranial tumors was increased, but there was no specific change in proportion of tumors.

A 39-year-old female patient presenting with epigastric discomfort and jaundice was diagnosed as diffuse hilar cholangiocarcinoma with vascular tumor invasion. After preoperative management with percutaneous transhepatic biliary drainage and right portal vein embolization, the patient underwent modified hepatoligamentopancreatoduodectomy; this included extended right hepatectomy, caudate lobectomy, portal vein segmental resection, enbloc resection of hepatoduodenal ligament together with proper hepatic artery resection and with leaving a replaced left hepatic artery from the left gastric artery, and paraaortic lymph node dissection. Intraoperative frozen histologic examination revealed multiple paraaortic lymph node metastases, which was generally regarded as definite distant metastasis. There was no postoperative complication except for persistent drainage of ascites that occurred only during the immediate postoperative period. She did not receive postoperative adjuvant chemotherapy or radiotherapy. The patient is now living well 11 years 2months after surgery without recurrence. Although this patient revealed hilar vascular invasion and paraaortic lymph node metastasis, she survived more than 10 years without tumor recurrence. This implicate that aggressive surgical treatment of hilar cholangiocarcinoma can result in long-term survival even in the presence of paraaortic lymph node metastasis.

PURPOSE: To assess the role of the preoperative portal vein embolization (PVE) in patients in need of major hepatectomy. MATERIALS AND METHODS: Total of 11 cases consisted of Klatskin tumor (n:6), gallbladder cancer (n=2), and hepatocellular carcinoma (n=3). After percutaneous transhepatic puncture of portal vein (right:7, left:4), the embolization of 1st order branch of right portal vein was done with Gentamicin soaked Gelfoam cubes. Radiologically, the angle between the middle hepatic vein and the inferior vena cava was measured on pre- and post-PVE CT (F/U :10 days) to evaluate the hypertrophy of the left lobe. Clinically, amount and nature of the drained bile through the PTBD tube of both lobes were analyzed in 5 patients with Klatskin tumor. The interval between PVE & operation was 10-24 days. Operative findings & the changes of postop. total bilirubin were analyzed and the complication after procedure was checked. RESULTS: There was decrease in mean angle between the middle hepatic vein and the inferior vena cava from 35.9 degree to 23.9 degree, but it was insignificant statistically (p=0.09). The embolization of right portal vein was done and there was increase in amount of drained bile from the nonembolized left lobe by 2-3 folds 8-14 days after PVE. The color and consistency between both lobes were significantly different; right lobe was darker in color and softer in consistency. Postoperative total bilirubin increased by 2-3 folds 1 to 4 days after PVE and normalized 10 to 14 days after PVE. Most of the patients had mild abdominal pain and fever after PVE and 1 patient had localized hematoma at puncture site which was subsided spontaneously. CONCLUSION: The preoperative portal vein embolization is a useful method for minimizing postoperative liver failure in patients in need of major hepatectomy.

PURPOSE: Liver transplantation (LT) is regarded as an important management option for fulminant hepatitis (FH), which is associated with considerable mortality under conservative management. The aim of this study was to evaluate the outcome of children with FH according to management. METHODS: We reviewed medical records of patients presented with FH from January 1994 until April 1999. The children were grouped according to the treatment. Group A was classified for supportive treatment only and group B for supportive treatment plus LT. Children were considered as candidates for LT if the level of factor V decreased to below 20% of normal or the patient's condition deteriorated despite intensive care during the initial 48 hours. Underlying disease, duration after jaundice, grade of encephalopathy, laboratory findings, treatment and outcomes were analyzed. RESULTS: The study group comprised 7 females and 8 males aged from 8 months to 15 years old (median age of 4 years). The causes of FH were Wilson disease (4 cases), Epstein-Barr virus infection (1 case), drug (1 case) and idiopathic (9 cases). There were 5 children in group A and 10 in group B, and there were no significant differences in age, sex ratio, underlying diseases, grade of hepatic encephalopathy and laboratory findings between the two groups. One out of 5 in group A and 9 out of 10 in group B survived. But all the children in group A who met the criteria for LT and received only supportive care died. One out of 10 in group B died because of grade IVa hepatic encephalopathy which advanced to brainstem herniation. CONCLUSION: This study showed that patients who were managed with supportive care only, although LT was indicated, died and that 9 out of 10 who received LT survived. Therefore, we suggest LT should be considered in the management of FH.

The treatment of choice for Cushing's disease is surgical removal of tumor, the source of ACTH overproduction. In occasional patients in whom a surgical approach including total adrenalectomy is not feasible or surgical removal of tumor is not complete, medical treatment may be necessary because pituitary irradiation requires a long 1ag time to remission. Although ketoconazole, an imidazole derivative with inhibitory activity on adrenal steroidogenesis has been reported to be effective in the treatment of Cushing's disease, the limited effectiveness in lowering very high level of cortisol and occasional hepatotoxicity restrains its wide use. In this report, we describe a woman with Cushing's disease due to pituitary microadenoma. Transsphenoidal pituitary adenomeetomy followed by ketoconzole treatment had been unsuccessful in achieving remission of the disease, but combined treatment with ketoconazole and octreotide accomplished successful reduction in cortisol production.

BACKGROUND: Leptin, produced in the adipose tissue, is involved in the regulation of body weight. The release of the leptin is increased in obese adults even in children. This study investigated whether the serum leptin in cord blood was related to babys birth weight and metabolic parameters. METHODS: 71 pairs of singleton pregnancy babies and their mother were studied. Babies are classified in LGA (large for gestational age), AGA (appropriate for gestational age), SGA (small for gestational age) three groups. After delivery, cord blood and maternal venous blood samples were drawn. We measured the plasma leptin, insulin-like growth factor (IGF)-1, insulin and proinsulin in cord and maternal serum. RESULTS: The concentration of leptin from cord blood was increased in LGA babies and decreased in SGA babies compued with the level in AGA babies. There was positive correlatian (r=0.55, p<0.01) between the plasma leptin level in cord and birth weight. There were positive correlatian between both the plasma proinsulin (r=0.37, p<0.01) and IGF-1 (r=0.32, p<0.01) and birth weight, too. But there was no difference between female and male baby's cord blood leptin level. In multiple regression analysis, cord blood leptin level was found independent factor related to birth weight ( p=0.001) CONCLUDION : The plasma leptin, proinsulin and IGF-1 is correlates to the birth weight. These data provide evidence that leptin and proinsulin are highly related to the nutritional status already during the fetal periods, and effect on the intrauterine fetal growth.

OBJECTIVE: To analyze the causes of arterial bleeding after living donor liver transplantation (LDLT) and to evaluate the efficacy of transcatheter arterial embolization (TAE). MATERIALS AND METHODS: Forty-two sessions of conventional arteriography were performed in 32 of the 195 patients who underwent LDLT during the past 2 years. This was done in search of bleeding foci of arterial origin. TAE was performed with microcoils or gelatin sponge particles. The causes of arterial bleeding, the technical and clinical success rates of TAE and the complications were retrospectively evaluated. RESULTS: Forty-two bleeding foci of arterial origin were identified on 30 sessions of arteriography in 21 patients. The most common cause of bleeding was percutaneous procedures in 40% of the patients (17 of the 42 bleeding foci) followed by surgical procedures in 36% (15/42). The overall technical and clinical success rates of TAE were 21 (70%) and 20 (67%) of the 30 sessions, respectively. The overall technical success rate of TAE for the treatment of bleeding from the hepatic resection margin, hepatic artery anastomotic site and hepaticojejunostomy was only 18% (2/11), whereas for the treatment of bleeding in the other locations the technical and clinical success rates of TAE were 100% and 95%, respectively. No procedure-related major complications occurred. CONCLUSION: In the case of arterial bleeding after LDLT, percutaneous procedure-related hemorrhages were as common as surgery-related hemorrhages. There were technical difficulties in using TAE for the treatment of hepatic arterial bleeding. However, in the other locations, TAE seems to be safe and effective for the control of arterial bleeding in LDLT recipients.

We recently encountered a case of posttraumatic SMAVF(Superior mesenteric arteriovenous fistula), which has treated by coil embolization. He had history of stab wound and emergent operation. Operative diagnosis was gastric perforation and mesenteric laceration which was simply repaired. After history of abdominal stab woung and operation, he developed palpitation and thrill in left upper abdomen. Recentrly he have experienced syncope twice. On superior mesenteric arteriogram, early visualiation of superior mesenteric vein and portal vein was noted. We embolized the SMAVF by using coils. Since coil embolization, palpitation and thrill disappreared.
