Transcatheter hepatic arterial embolization (THAE) is one of the treatment modalities that can be applied to hepatocellular carcinomas (HCC) and metastatic tumors of the liver. Complications such as cholecystitis and gallbladder necrosis, are common with THAE, but liver and peripheral bile duct necrosis are rare, and intrahepatic stones with main bile duct necrosis have never been reported. To prevent intrahepatic spread during operative manupulation and to decrease the vascularity and size of the tumor, we performed a THAE on a huge-sized HCC five times before performing the hepatectomy. We succesfully undertook a right lobectomy after the THAE with lipiodol, gelform, and adriamycin. However, severe bile duct stricture and intrahepatic stones were confirmed during the operation.

BACKGROUND AND AIMS: When acute gastric anisakiasis is clinically suspected, endoscopic removal of larva is the only definite treatment method. However, there has been little known for endoscopic findings of gastric anisakiasis. METHODS: In 39 patients with gastric anisakiasis, the ingested species of marine products and clinical findings were investigated. The form of larvae, the mucosal changes of the insertion site, close and distant area were also analysed during endoscopic examination. RESULTS: Twelve patients (30.8%) ate raw Astroconger myriaster solely, and the most frequent mucosal insertion site of larvae was around the greater curvature of the body (59.5%). Endoscopic findings of erosion (33.3%), hemorrhagic erosion (33.3%) and redness of the mucosa (11.9%) were observed at the insertion site. The adjacent mucosal changes were edema and fold enlargement. All patients were treated medically. CONCLUSIONS: When acute gastric anisakiasis is suspected, the careful endoscopic examination of larva was necessary for confirmatory diagnosis and definite treatment of the disease.

We describe a patient with cutaneous angiocentric immunoproliferative lesion (AIL) associated with the Epstein-Barr virus (EBV). An organ system survey revealed no evidence of internal involvement. A skin biopsy specimen .showed infiltrating cells involving mainly deeper dermis and subcutaneous tissue. An examination of the reticular dermis revealed polymorphous angiocentric and angioinvasive infiltrate containing some atypical lymphocytes and histiocytes. EBV encoded RNA (EBER) was demonstrated in lesional skin by the in situ hybridization technique. On the basis of these findings, we conclude that our case may represent a form of AIL associated with EBV showing histologic features of classical lymphomatoid granulomatosis.

Myelopathy or dysfunction of the spinal cord, can be caused by degenerative processes of the cervical vertebrae. Cervical spondylotic myelopathy can be divided into five distinct syndromes on the basis of clinical presentation by Ferguson. Absolute indication for surgery is the progression of neurologic deficit. Decompression may be achieved using an anterior, posterior, or a combined approach, but each patient has unique clinical conditions that require individualized treatment. The purpose of the study was to evaluate the operative results by the clinical manifestation. In evaluating the results, the evaluation system established by the Japanese Orthopedic Association was employed. The average preoperative score in the 14 patient was 8.7 points and the average postoperative score was 12.7 points. The better results have been obtained for those who were managed with decompression within 1 year after onset of symptoms and those who had lateral type. In conclusion, the prognosis for the recovery of the spinal cord function is related with the onset of clinical symptoms and degree of neurological deterioration, so early detection and operative decompression for cervical spondylotic myelopathy may be the best method for the prevention of those unwanted and potentially devastating neurological deteriorations.

Acute esophageal necrosis (AEN) is a very rare disorder typically presenting as a diffuse black esophageal mucosa on upper endoscopy. For this reason, AEN is often considered to be synonymous with 'black esophagus'. The pathogenesis of entity is still unknown. We report a case of AEN with duodenal ulcer causing partial gastric outlet obstruction. A 53-year-old man presented with hematemesis after repeated vomiting. The upper gastrointestinal endoscopy revealed circumferential black coloration on middle 315 to lower esophageal mucosa that stopped abruptly at the gastroesophageal junction. Pyloric ring deformity and active duodenal ulceration with extensive edema was observed. After conservative management with NPO and intravenous proton pump inhibitor, he showed clinical and endoscopic improvement. He resumed an oral diet on day 7 and was discharged. In our case the main pathogenesis of disease could be accounted for massive esophageal reflux due to transient gastric outlet obstruction by duodenal ulcer and following local ischemic injury.

OBJECTIVE: The purpose of this study is to evaluate the accuracy and safety of pedicle screws in the treatment of thoracic spine disease. METHODS: Thirty-eight patients who had undergone thoracic pedicle screw fixation between January 2003 and December 2007 were retrospectively studied. Postoperative computed tomography scans were obtained using 3-mm axial cuts to evaluate the pedicle screw placement. The screws were further evaluated by the location and degree of the perforation. RESULTS: Of the 214 thoracic pedicle screws placed, 174 (81.3%) were fully contained within the pedicle or anterior cortices of the vertebral body. Of the remaining 40 (18.7%) screws, 25 (62.5%) were lateral perforations, 12 (30.0%) were medial perforations, and 3 (7.5%) were anterior perforations of the vertebral body. The screws inserted at T1-T4 (28.5%) and T5-T8 (34.8%) revealed a higher perforation rate than the screws inserted at T9-12 (11.4%). No neurologic or vascular complications were encountered, but one screw 6 mm above a medial perforation required reinsertion. CONCLUSION: Although clinical outcomes were not affected by mild displacement of thoracic pedicle screws, accurate measurements and considerable experience were required in the placement of screws, especially screws placed in the upper and midthoracic spine.

OBJECTIVE: The clinical and radiographic success of a two-level discectomy and autologous iliac bone fusion with anterior cervical plate fixation (ACDFP) was compared with that of a one-level corpectomy and fusion using a titanium mesh cage (corpectomy) for the treatment of degenerative cervical disc disease. METHODS: From January 2004 to December 2007, there were 45 consecutive cases of two disc level degenerative cervical disc disease treated with either ACDFP or corpectomy. The medical records and radiological studies were reviewed, retrospectively. The clinical outcomes were measured using Odom's criteria. The radiologic assessment was performed using images showing the lordosis and bony fusion. RESULTS: Twenty-seven patients were treated with ACDFP. Eighteen patients were treated with corpectomy. The clinical outcome was excellent or good in 25 cases (93%) and 17 cases (94%) treated with ACDFP and corpectomy, respectively. The fusion rate was 96% and 94% for ACDFP and corpectomy, respectively. There was a slight increase in the cervical lordosis in both groups, but there was no significant difference between the 2 groups. There were no irriversible complications in both groups. Reversible complications were encountered in 1 case of corpectomy, and 7 cases of ACDFP, which were mainly associated with donor site. CONCLUSION: Either a ACDFP or a corpectomy provides good clinical outcome and similar bone fusion rates for degenerative disc diseases. However, absence of donor site complications makes a corpectomy better than ACDFP.

To evaluate the usefulness of computed tomography (CT) in radiotherapy treatment planning in malignant tumors of thoracic cage, the computer generated dose distributions were compared between plans based on conventional studies and those based on CT scan. 22 cases of thoracic malignancies, 15 lung cancers and 7 esophageal cancers, diagnosed and treated in Department of Therapeutic Radiology of Seoul National University Hospital from September, 1982 to April, 1983, were analyzed. In lung cancer, dose distribution in plans using AP, PA parallel opposing ports with posterior spinal cord block and in plans using box technique both based on conventional studies were compared with dose distribution using AP, PA and two oblique ports based on CT scan. On esophageal cancers, dose distribution in plans based on conventional studies and those based on CT scans, both using 3 port technique were compared. The results are as follows: 1. Parallel opposing field technique were inadequate in all cases of lung cancers, as portion of primary tumor in 13 of 15 cases and portion of mediastinum in all were out of high dose volume. 2. Box technique was inadequate in 5 of 15 lung cancers as portion of primary tumor was not covered and in every case the irradiated normal lung volume was quite large. 3. Plans based on CT scan were superior to those based on conventional studies as tumor was demarcated better with CT and so complete coverage of tumor and preservation of more normal lung volume could be made. 4. In 1 case of lung cancer, tumor localization was nearly impossible with conventional studies, but after CT scan tumor was more clearly defined and localized.
