Early gastric cancer is defined carcinoma that is limited to the gastric mucosa and submucosa and that does not extend into the muscularis propria. The development and widespread use of upper gnstrointestinal endoscopy with biopsy and cytology have enhanced our ability to make early diagnosis of gastrie carcinoma. Gastric cancinoma is being diagnosed at an ealry stage aad the survival rates for these patients are significantly greater than those with advanced gastric carcinoma. These ealry lesion can be cured in over 90% of the cases. In fact, it is almost impossible to follow up cases of early gastric cancer without surgical treatment. We report a case developed advanced gastric carcinoma 34 months after initial endoseopic diagnosis of early gastric cancer. A, 48-year-old woman was diagnosed early gaatrie cancer on June 21, 1985 by endoscopy. Proper surgical intetvention was not carried out due to her liver cirrhosis. The follow-up endoscopic examination was done on March 16, 1988. The gastric cancer looked like an advanced stomach and extended to other site.

PURPOSE: Differential diagnosis of solitary pulmonary nodule with cavity includes lung abscess, tuberculoma, bronchogenic carcinoma, metastasis and trauma, etc. We analyzed the CT appearance of tubercuioma presenting as a solitary pulmonary nodule with cavity and describe the findings which suggest tuberculoma in the differential dignosis of soliary pulmonary nodule with cavity. MATERIALS AND METHODS: 25 patients with solitary pulmonary nodule(diameter less than 4 cm) without surrounding parenchymal consolidation on chest radiograph, who had a cavity within the nodule on CT, were included in our study. Density of the nodule, maximal wall thickness, the character of inner and outer wall margin, location of cavity within the nodule, location of the nodule, presence or absence of satellite lesions and calcification were analyzed. RESULTS: Solitary tuberculoma with cavity showed maximal wall thickness more than 15 mm in 40%(10/25) and 5-14 mm in 56%(14/25), eccentric cavitation in 84%(21/25) and concentric cavitation in 16%(4/25), spiculated outer wall margin in 56%(14/15) and Iobulated margin in 32%(8/25), smooth inner wall margin in 60%(15/25) and nodular margin in 40%(10/25). CT density of the cavity wall compared with the chest wall muscle was low in 84%(21/25) and isodense in 16%(4/25). Accompanying satellite lesions were seen in 84% (21/25) and calcification was visible in 28%(7/25). CONCLUSION: The CT findings of solitary tuberculoma with cavity are relative peripheral location, eccentric cavitation, finely spiculated outer wall margin, and mean maximal wall thickness of 13.2 mm, which are also the common features of malignant nodule. However, relative low density of the nodule compared to the chest wall muscle and surrounding satellite lesions can be additional clues favoring solitary tuberculoma with cavity on CT.

Surgical removal of impacted mandibular third molars frequently require tooth sectioning or bone removal. In this study, 361 mesioangular or horizontal impacted mandibular third molars are removed surgically by tooth section, the methods of tooth section are classified as 4 stages and 12 grades in the number of times and technics of crown or roots section and difficulties. Grades and their cases are followings: 1. occlusal crown first section(100, 28%) 2. distal crown first section(69, 19%) 3. occlusal crown second section(29, 8%) 4. distal crown second section(52, 14%) 5. occlusal crown first section and root section(10, 3%) 6. distal crown first section and root section(27, 7%) 7. occlusal crown third section(3, 1%) 8. distal crown third section(22, 6%) 9. occlusal crown second section and root section(13, 3%) 10. distal crown second section and root section(17, 5%) 11. occlusal crown third section and root section(2, 1%) 12. distal crown third section and root section(17, 5%)

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.
