Two Cases of Colon Adenocarcinoma Transformed from Colonic Adenoma / 대한소화기내시경학회지

The prevalence of colorectal cancer is increasing now in Korea and the principal strategy of its management is early detection and surgical resection. Current discussion of the topic of colorectal polyps and cancer is largely based on the concept of the adenoma-carcinoma sequence, which is thought to be the most probable pathogenesis for colorectal cancer. But the case reports about colonic adenocarcinoma arising from adenoma in clinical practice between short interval are rare in Korea. We experienced two cases of colon cancer, which were transformed from small adenoma can not be removed because of patients' refusal, 3 years ago. So we present these cases with a review of relevant literatures.

A Case of Bleeding from Rectal Dieulafoy-like Lesion Treated by Endoscopy / 대한소화기내시경학회지

Dieulafoy-like lesion is a relatively uncommon disease which is a potential source of life-threatening gastrointestinal bleeding. The lesion comprises mainly of an abnormally large submucosal artery that protrudes through a small mucosal defect. The lesion is frequently found at distal portion of gastroesophageal junction but may occur anywhere in gastrointestinal tract including small bowel, colon and rectum. Moreover bleeding from dieulafoy-like lesion of rectum is very reae. It has been reported that rectal Dieulafoy-like lesion is very rare source of lower gastrointestinal bleeding and its pathogenesis may be associated with constipation. Recently, endoscopy has an important role in the diagnosis and treatment (including injection and coagulation therapy) of bleeding from Dieulafoy-like lesion. We herein report a case of a patient who presented wih massive hemorrhage from a small rectal ulcer with adherent blood clots. Bleeding was controlled with endoscopic treatment by utilizing bipolar electrocoagulation without complication and recurrence.

Three Cases of the Gastric Carcinoid Tumor Combined with the Gastric Adenoma / 대한소화기내시경학회지

Carcinoid tumor in the stomach is neuroendocrine tumor originated from enterochromaffin cells in submucosa in the stomach. It is very rare, account for 0.3% of gastric tumor. It is likely to be demonstrated with other tumor in the stomach simultaneously, such as adenocarcinoma. According to paper published in Korea, it is only 4 cases that gastric carcinoid combined with other gastric tumors have been reported. But there has been no reports of gastric carcinoid combined with gastric adenoma, such as our cases. We report 3 cases of gastric carcinoid tumor combined with atypical adenoma, with review of paper presented.

The Parascalene Technique of Brachial Plexus Block for the Operation of the Upper Extremity and Shoulder / 대한마취과학회지

BACKGROUND: Brachial plexus is invested by a fascial envelope, which forms a perineural and perivascular space that extends all the way from the cervical intervertebral foramen to the distal axilla. Therefore a single injection of a local anesthetic into any sites of this space can provide anesthesia of the entire brachial plexus. Nowadays many methods of brachial plexus block have been developed but there are some severe complications and they can't prevent tourniquet pain completely. METHODS: We have performed parascalene technique for brachial plexus block in 206 cases from Jan., 1992 to Dec.,1994. We studied the cases retrospectively by reviewing patients' anesthesia records. The technique for parascalene block is the injection of local anesthetic solution into the lower part of the posterior triangle of the neck at the point 1.5~2.0 cm above the clavicle at the lateral border of the anterior scalene muscle. RESULTS: We could provide the proper anesthesia for the upper extremity and shoulder operation without any remarkable complications except Honor's syndrome of 3 cases. And there were no tourniquet pain in all 96 cases who had used tourniquet. CONCLUSIONS: The parascalene approach is the useful, safe and reliable method for brachial plexus block.

A Case of Mediastinal parathyroid adenoma localized by technetium-99m sestamibi scanning / 대한내분비학회지

We present a patient with primary hyperparathyroidism in whom preoperative Tc-99m sestarnibi scanning cleary demonstrated mediastinal parathyroid adenoma. After resectian of tumor through median sternotomy, he was restored to the normocalcemia. This case suggests that Tc-99m sestamibi scanning may be a useful method in the preoperative localization of mediastinal parathyroid adenoma.

Dosage Dependent Neurologic Impairment after Cerebral Air Embolism in Rabbit / 대한마취과학회지

BACKGROUND: A long-term objective is to understand the pathogenesis of neurologic injuries associated with cardiac surgery, cardiopulmonary bypass, and circulatory arrest. Our specific aims are to establish a dose of air which results in moderate to severe neurologic defects in normothermic (37degrees C) rabbits. METHODS: To first establish a dose of air which would cause unequivocal neurologic impairment, anesthetized rabbits received either 0, 50, 100 or 150 microgram l/kg of air into the internal carotid artery(n=5 in each group). One hour later, anesthesia was discontinued and animals were recovered. Animal were neurologically evaluated at 24 hours using a zero(normal) to 97(coma) point scale. RESULTS: There was a clear relationship between the dose of air injected and the severity of neurologic impairment at 24 hours, p=1.1x10(-7). Rabbits receiving 50 micrograml/kg of air were minimally affected and were difficult to distinguish from controls. In contrast, rabbits receiving 150 micrograml/kg of air were uniformly and unequivocally impaired. CONCLUSION: we recommend for future cerebral air embolism studies, 150 microgram l/kg as the optimal dose of air which would reliably produce viable subjects for 24 hours with marked unequivocal, neurologic impairment.

Comparison of Coronary Angiographic Findings between Patients with and Those without Stable Angina Pectoris Prior to Acute Myocardial Infarction

BACKGROUND: Many investigators found that there were more severe and extensive atherosclerosis in patients with stable angina pectoris than those with unheralded acute myocardial infarction(AMI). But coronary angiographic findings in patients with or without stable angina pectoris(SAP) prior to acute myocardial infarction are somewhat controversial. And in many articles that compared the coronary angiographic findings between patients with and those without angina prior to acute myocardial infarction, the definition of angina and significant coronary artery stenosis were not uniform. So, coronary angiographic finding were compared between patients with and those without stable anginal pectoris prior to AMI according to scoring system suggested by Bogarty. METHOD: Coronary angiography was performed in 141 patients with AMI. Angiographic findings of patients with SAP prior to AMI were compared to those without SAP prior to AMI. Risk factors of coronary artery disease were also compared. RESULTS: 1) Numbers of the patients with SAP were 34(24%) and those without SAP were 107(76%). 2) Numbers of stenosed vessels, Numbers of tenosed lesions, extent index and percent of diffuse pattern were higher in SAP group(p<0.05). 3) Numbers of diseased vessels and occluded lesions were not different between two groups(Pvalue was 0.07 and 0.5, respectively). 4) patients with SAP were older than those without SAP(p = 0.03). 5) Sex ratio and prevalence of hypertension, diabetes and smoking were not different between two groups. 6) Lipid profiles were not different between two groups. CONCLUSION: Patients with SAP prior to AMI had more severe and extensive atherosclerosis than those without stable angina pectoris prior to AMI.

A Case of Primary Sclerosing Cholangitis with Ulcerative Colitis / 대한소화기내시경학회지

Sclerosing cholangitis is cholestatic disease, characterized by progressive fibrotic inflammation and obliteration af intrahepatic bile ducts and extrahepatic bile ducts and sometimes associated with ulcerative colitis. The pathogenesis of this disease is not understood well. In this disease, however, have been proposed infectious agent, endotoxin of bacteria and immunological event. In Europe and U.S.A., the incidence of sclerosing cholangitis associated with ulcerative colitis was between 2,4 and 4.0 percent. The association is strongest in patients with pancolitis, with a prevalenee of 5.5 percent, compared with patients with disease confined to the distal colon, with a prevalence of 0.5 percent. But, in Korea, it has not been reported sclerosing cholangitis associated with ulcerative colitis. A 30-year old man was diagnosed as an ulcerative colitis 9 years ago and has been followed up, intermittently. Recently, he has experienced hematochezia and dizziness. Colonoscopy showed active ulcerative colitis(pancolitis), blood chemistry elevated alkaline phosphatase and y-GTP. ERCP and liver biopsy specimen revealed sclerosing cholangitis. we concluded that this case was a sclerosing cholangitis as a complication of ulcerative colitis and the first case report of primary sclerosing cholangitis with ulcerative colitis in Korea, Hence, we reported a case of primary sclerosing cholangitis with ulcerative colitis with a review of literatures.
