Carcinoid tumors arise from enterochromaffin cells that are located predominatly in the gastrointestinal mucosa. The vast majority of rectal carcinoid tumors are benign and can be safely treated by local excision. Lesions larger than 2 cm and invading the museular wall of the rectum should be considered malignancy and treated by more radical surgery such as abominoperined resection. We report 6 cases of rectal carcinoid tumor, three cases of them were less than 1 cm in size without metastasis. Two of these, small carcinoid tumor were treated with endoacopic polypectomy and one was treated with segmental resection. The others were 2.0 cm or larger in size with regional or liver mestasis. They were treated with segmental resection or electrical fugalization for tumor and transcatheter arterial embilization for liver metastasis or none.

Traditionally, radical hysterectomy is the main surgical method for the treatment of early cervical carcinoma and always results in the loss of fertility. But, large numbers of young women are recently being diagnosed with cervical carcinoma and fertility preservation has become a concern. So, there has been a move towards more conservative approaches for the treatment of cervical carcinoma in recent years. Radical trachelectomy, which allows preservation of uterus but removes the cervix, parametrium and upper one third of the vagina, is a conservative but locally radical procedure. We performed radical abdominal trachelectomy with pelvic lymphadenectomy for two cases of invasive cervical carcinomas, which may be the first report in korea. One patient was 37 years old single women who had stage Ib cervical cancer and was disease free for 17 months after treatment. The other patient was 19 years old student who was also single and had stage IIa cervical cancer and was disease free for 14 months after treatment. We report the first two cases and review the literature on radical trachelectomy.

BACKGROUND AND OBJECTIVE: Percutaneous transluminal coronary angioplasty of chronic total occlusion has been limited by a relatively low success rate and a high restenosis rate. This study investigated procedural outcome, factors predictive of procedural success and safety of coronary angioplasty for chronic total coronary occlusion. MATERIALS AND METHODS: The study population was composed of 45 lesions attempting PTCA with or without stent implantation for recanalization of chronic total coronary occlusion between January 1997 and July 1999. The clinical and angiographic data of the 45 lesions were reviewed. The results of successful PTCA in 28 lesions were compared with those in 17 lesions whose PTCA was failed. RESULTS: The overall success of balloon angioplasty and stenting was achieved in 28 lesions (62.2%) and did not differ significantly by clinical variables. The most common cause of failure of balloon angioplasty was inability to pass the guide wire across the occlusion( 14 of 23 lesions, 61%). Procedural success was more common in patients with occlusions with a tapered entry configuration(77.2% vs. 47.8%, p=.042), with lesions without side branches(82.3% vs. 50%, p=.03). Multiple logistic regression analysis identified the absence of side branch(p<0.01) and the presence of a tapered entry configuration(p<0.05) as independent predictors of procedural success. One case(2.2%) needed emergency coronary bypass surgery after failure to recanalize the occluded vessel. There was no Q wave acute myocardial infarction, death. CONCLUSIONS: The favorable cases(>60%) of chronic total coronary occlusions can be successfully dilated by balloon angioplasty with or without stent implantation, with a major complication rate of 2.2%. Therefore, with careful patient selection, we need to try the aggressive recanalization for chronic total coronary occlusion.

Serum aspartate aminotransferase (AST) is a common enzyme for the evaluation of the hepatic, muscular and cardiac diseases and is produced also at kidney, brain, pancreas, lung, leukocytes, erythrocytes, etc. The elevation of its activity is usually caused by the necrosis of hepatocytes when there are not muscular injuries or myopathies. Recently, it is found that AST can exist as a macroenzyme by forming a complex with an immunoglobulin and this complex is erroneously considered to indicate the presence of liver disease as a result of elevation of AST activity on routine blood chemistry analysis. We experienced the patient with isolated AST elevation due to the formation of AST-mmunoglobulin complex confirmed by AST isoenzyme electrophoresis (EP).
