Most patients with carcinoma of the cervico-thoracic esophagus present with locally advanced disease. For this reason, therapeutic efforts have been largely palliative, focused on eradicating locoregional dis- ease, and have been attended by high morbidity rates. A 61 year old man was diagnosed to advanced cervicothoracic esophageal cancer(Type 1) and reli ved concurrent chromo-radiotherapy for 2 months in St. Mary's Hospital. And then he underwent transhiatal subtotal esophagectomy and radical dissection of cervical and superior mediastinal Iymph nodes with thoracoscopy. The histologic diagnosis was early esophageal cancer(Type 0-llb, SM2) and the curability of operation was calculated to highly curative(Clll). And the postoperative course was unevenful.

We describe a case of adult tracheoesophageal fisula incidentally found during laparotomy. A 41 year old male came to the emergency room due to multiple injuries from a car accident. An emergent laparotomy was given to the patient to rule out hemoperitoneum, and progressive distension of the stomach was noted with each positive pressure ventilation. The diagnosis of tracheoesophageal fistula was made via an intraoperative esophagogram. Detailed inquiry of the patient's history from his mother together with extensive destructive changes over the right upper lung field on the patient's chest X ray suggested that the fistula was longstanding and not of traumatic origin, obviating the need of urgent operation. The fistula was divided via the right thoracotomy 24 days later. Postoperative course was uneventful.

Hemangioma in the esophagus is an uncommon tumor. There have only been about 30 cases reported in the world literatures. It occurs predominantly in men and although majority are asymptomatic, may cause bleeding and dysphagia. Hemangioma in the esophagus was diagnosed with a barium swallowed esophagography and endoscopy. The main treatment modes recommended are surgery and endoscopic resection. We experienced one case of cav ernous hemangioma occurring at the distal esophagus. The patient was a forty-six year old male with dysphagia and indigestion. Barium esophagogram showed a filling defect at the distal portion. Esophagoscopy showed a bluish polypoid mass. Surgical resection was per formed and the pathologic diagnosis was confirmed as cavernous hemangioma. Postoperative course was uneventful and the patient had been followed up without any problems.

A 21 year old male patient was admitted for pain, edema and a tingling sensation in his right arm. He underwent venography and an MRI scan, and he was diagnosed with Paget-Schroetter syndrome. Thoracoscopic first rib re-section was performed after failure of thrombolytic therapy, The symptoms were relieved after the operation and he was discharged with warfarin medication. First rib resection is generally performed through the standard transaxillary or supraclavicular route. We report here on a successful thoracoscopic first rib resection.

Coronary artery spasm immediately after the coronary artery bypass graft (CABG) surgery is rare but it can cause sudden and severe hypotension or a ventricular arrhythmia. We report a case of low cardiac output syndrome caused by a right coronary artery spasm following CABG that did not show any significant stenotic lesions on preoperative coronary angiography.

Purpose: Myocardial perfusion scintigraphy is a useful technique to diagnose and to predict prognosis in patients with suspected or known coronary artery disease. The purpose of the present study is to evaluate the prognostic value of normal exercise $^{99m}Tc$-MIBI myocardial perfusion single photon emission computed tomography (SPECT) and to analyze results with regard to those of exercise electrocardiography or coronary angiography. Materials and Methods: We evaluated 301 patients (mean age $52{\pm}10$ years, 166 males and 135 females) with normal exercise $^{99m}Tc$-MIBI myocardial perfusion SPECT performed for suspected coronary artery disease. Subject were evaluated for cardiac events and followed for 8-55 months (mean $19{\pm}10$ months) after imaging. Results: During the follow-up period, there was no cardiac death but only one non-fatal myocardial infarction (event rate 0.21% per year). In addition, only one patient underwent coronary revascularization. There was no significant difference in cardiac event rate between patients with positive (n=27) and negative (n=235) exercise electrocardiography (p:NS). There was no cardiac event in 17 patients who underwent coronary angiography (4 patients with >50% luminal narrowing, 2 patients with vasospasm and 11 patients with no significant lesion). Conclusion: Patients with normal exercise $^{99m}Tc$-MIBI myocardial perfusion SPECT has a very low risk for cardiac events regardless of exercise electrocardiographic and coronary angiographic findings.

Background: Myxoma makes up close to 50% of adult primary cardiac tumors, and this mainly occurs in the left atrium, and rarely in the right atrium or ventricle. The patients clinically present with symptoms of hemodynamic obstruction, embolization or constitutional changes. Diagnosis is currently established most appropriately with 2-D echocardiography. Surgical resection of myxoma is a safe and effective treatment, Material and Method: We reviewed our clinical experience in the diagnosis and management of 57 cases of cardiac myxoma that were seen over a 20-year period from July 1984 to July 2004. Result: The mean age of the patients was $53.5{\pm}14.0$ years (range: 12 to 76 years). There were 38 (67%) females and 19 (33%) males. The preoperative symptoms included dyspnea on exertion in 27 patients, palpitation in 4, chest pain in 9 and syncopal episode in 4. The diagnosis was made by echocardiography alone in 51, and by combination of echocardiography, CT and angiography in 6. The tumor attachment sites were the interatrial septum in 50, the mital valve annulus in 3 and the left atrial wall in cases, The tumor was excised successfully via biatriotomy in 33 (58%), left atriotomy in 15 (26%), the septal approach via right atriotomy in 3, Inverted T incision in 3 and the extended septal approach in 3. The follow-up time ranged from 1 to 229 months (mean follow-up: $84.0{\pm}71.3$ months). There were no early and late deaths and no recurrence during the follow-up period except for follow-up loss in 5 patients. Conclusion: It's concluded that excision of cardiac myxoma is curative and the long-term survival is excellent. Immediate surgical treatment was indicated because of the high risk of embolization or of sudden cardiac death. Radical tumor excision may prevent recurrences.

Background: Some controversy still exists concerning the operative indications of coronary fistulas. Nevertheless, a short-term and long-term outcomes are excellent with surgical interventions. In this study, we assessed our surgical results on this disease entity during the last 20 years. Anatomic diversity was described as well. Material and Method: From April 1986 to March 2005, 20 patients with coronary fistulas underwent surgical correction in Seoul National University Children's Hospital. Their medical records were reviewed retrospectively. Result: Twelve patients ($60\%$) were asymptomatic prior to surgery. All had electrocardiogram and echocardiogram and all but 3 had coro-nary angiogram preoperatively. Anatomically, none of them had two or more coronary fistulas. The sites of origin were left coronary system in 11 patients and right in 9. The draining sites were right ventricle in 11, right atrium in 3, left ventricle in 3, main pulmonary artery in 2, and superior vena cavae in 1. All of the involved, the coro-nary arteries were dilated or aneurismal. In 1 case, there was atherosclerotic change but no ischemic evidence in preoperative electrocardiogram. Operative techniques included external obliteration (13), internal obliteration (5), and both (2). External obliteration was done by ligation of the fistulous tract only in T patients, by fstula ligation plus plication in 3 and by plication or patch closure via fistulotomy in 3. There was no operative mortality. All of postoperative morbidities including transient sinus arrhythmia (2), complete atrioventricular block (1), decreased left ventricular function (2), ventricular tachycardia (1), pericarditis (1), and seizure (1) improved on discharge. The mean follow-up was 55.1$\pm$50.2 months (4.0 months${\~}$18.0 years) and there were no recurrences of fistula. There was 1 second operation for aortic root aneurysm, which developed after external patch closure of right coronary fistula. Conclusion: We demonstrated here that coronary fistulas can be cured with excellent clinical outcome and low operative risk under precise diagnosis. Understanding the anatomic diversity will help to construct surgical plans.

Background: Although great concerns have been raised regarding the suitability of the use of the radial artery as a bypass conduit after transradial catheterization, there has been no studies that examined this issue in Korea. The purpose of this study was to compare clinical and angiographic results of radial artery grafting between patients with and without previous transradial catheterization. Material and Method: From January 2000 to February 2004, a total of 93 patients underwent coronary artery bypass grafting using the radial artery: 49 patients received preoperative transradial catheterization for coronary angiography (group I) and 44 patients did not (group II). These patients were retrospectively reviewed. Result: There was no significant difference in sex ratio, age, clinical diagnosis, risk factors, ejection fraction and early clinical outcomes between two groups. The graft patency rates in groups I and II were both 100% in the internal thoracic artery and in the radial artery, and 85% and 86% in the saphenous vein. respectively. The stenosis-free graft patency in groups I and II were 93% and 81% in the radial artery respectively but no statistical significance was shown. Conclusion: There was no significant difference in graft patency at postoperative coronary angiography between two groups. Radial artery graft after transradial catherization seems to be suitable for bypass conduit in short-term analysis.
