Background: This study assessed the efficacy of pulmonary metastasectomy for synovial sarcoma in adult patients. Methods: Fifty patients, diagnosed with pulmonary metastasis from June 1990 to August 2010, were reviewed retrospectively. Twenty-eight patients underwent complete pulmonary metastasectomy, and their survival was evaluated. Age, sex, time to metastatic progression, laterality, number of tumors, size of largest nodule, and number of metastasectomies were analyzed as potential prognostic factors. Results: In all, 29 patients underwent at least one pulmonary metastasectomy, and 51 resections were performed. One intraoperative mortality occurred, and the 5-year survival rate was 58.4%. Bilateral metastases and early metastatic progression were associated with poor survival in multivariate analyses. Conclusion: Surgical resection can be a good option for treating pulmonary metastasis in patients with synovial sarcoma. Repeated resection was feasible with low mortality and morbidity.

Purpose: Incidents of suicide attempt and acute poisoning in the elderly population is rising. This study investigated the clinical nature of acute poisoning and differences between the survival and mortality groups in the elderly. Methods: We retrospectively investigated 325 patients with acute poisoning who visited the emergency department. Patients were divided into two groups, one survival and one death group. Information regarding patient sex, age, root cause of poisoning, time of year of poisoning, type of intoxicant, duration of time between intoxicant ingestion and arrival at the emergency department, total length of hospital stay, and any previous suicide attempts and subsequent hospitalization were collected. An initial Glasgow Coma Scale (GCS) and an initial and final Poison Severity Score (PSS) for each patient was calculated. Results: The survival rate for men was higher than for women in this study. The most common reason of drug intoxication was suicide, with accidental ingestion and substance abuse occurring in descending frequency. Seasonal factors were reflected in the data with the highest number of incidents occurring in spring and the lowest number in winter. Compared with the mortality group, the survival group had a lower initial PSS with a higher GCS. Conclusion: We conclude that being female, having suicide as a root cause, agrochemicals as an intoxicant, low initial Glasgow Coma Scale and high initial Poisoning Severity Score, are all associated with poor prognosis.
From January 1984 to December 1991, One hundred sixty five patients with carcinomoa of the esophagus were treated surgically at the department of Thoracic and Cardiovascular Surgery, Seoul National University Hospital. Among them, hospital records were available in 121 patients and were included in this study. There were 115 men and 6 women, with ages ranging from 40 years to 79 years[mean age of 59.2 years]. The most frequent preoperative symptoms included dysphagia[72.7%], weight loss[60.3%], chest pain or discomfort[14.9%], general malaise[13.2%]. All were treated surgically: 100 patients were managed by curative or palliative resection with reconstruction, and 6 by palliative bypass surgery. In 15 patients, explorative thoracotomy or laparotomy was only done due to unresectability. [operability: 87.6%, resectability: 82.6%] All specimens[those from resectable 100 cases] were sent to pathology, and histopathologic examinations were done; squamous cell carcinomas were found in 95 cases, adenocarcinoma in l. Adenosquamous carcinomas were found in 3, and malignant melanoma in l. Postoperative complications occurred in 34 cases; anastomotic site leakage[10], which was followed by empyema in 9 of them, wound problem[7], hepatic failure[6], pneumonia [3], post-operative bleeding[3], chylothorax[2], post-operative stricture[2], sepsis[1], and tracheobronchial fistula[1]. Hospital deaths were in 6 cases[Hospital mortality: 5.0%]. During the follow up period, 26 patients were proven to be recurrence of cancer locally or distantly. The one, two, and five-year actuarial survival raf.es were 71.3$\pm$4.5%, 57.4$\pm$5.6%, 34.7$\pm$8.9%, respectively. The data from this study suggested that esophagectomy with reconstruction of gastrointestinal tract could be performed with a low operative mortality and a few serious postoperative complications and achieved reasonable long term palliation for carcinoma of the esophagus.
From August 1982 to December 1991, 58 consecutive infants with tetralogy of Fallot underwent primary repair. Age ranged from 22 days to twelve months [n=58, 8.7$\pm$2.7 months] and body weight from 3.1 to 13 kilograms [n=58, 7.8$\pm$1.7 kilograms]. Qne infant had absence of the pulmonary valve; one had Ebstein`s anomaly and one had supramitral ring. Thirty-two patients [56%] experienced anoxic spell. Preoperative pulmonary artery indices were measured in 38 cases, ranging 126-552mm2/M2BSA[n=38, 251$\pm$79mm2/M2BSA]. All infants required a right ventricular outflow tract patch; in 41, the patch extended across the pulmonary valve annulus, in 13 of them, monocusps were constructed. All had patch closure of ventricular septal defect. Two infants had REV operation for avoiding injury to the canal branch of the right coronary artery which cross the right ventricular out flow tract. Post repair PRV/LV were measured at operating room in 40 cases, which revealed mean value of 0.49$\pm$0.12 [range: 0.25-0.74]. The hospital mortality was 10.3% [6 patients], and causes of deaths were right heart failure due to sustained right ventricular hypertension[4] and right ventricular outflow tract obstruction, intractablesuraventricular tachyarrhythmia[1], hypoxia[1] due to residual right to left shunt across the atrial septal defect in patient associated with Ebstein`s anomaly. All infants were doing well at follow-up from 1 to 101 months[20.6 months /patient, 1, 072 patient-month] Serial postoperative echocardiograms revealed no residual ventricular septal defects and estimated RVOT gradients between 0 and 40 mmHg except 3 cases [50, 50, 60 mmHg]. There were no late deaths and late ventricular arrhythmias or congestive heart failure. Redo operations were done in 2 cases because of residual right ventricular outflow tract obstruction. This experience with infants with tetralogy of Fallot suggests that, if mortality is tolerable, eletive repair of tetralogy of Fallot could be reasonably undertaken during the first year of life, and even better results could be anticipated along with improvement of methods of myocardial protection and postoperative care.
Purpose: Combined resection of an invaded organ in advanced gastric cancer (AGC) with infiltration of adjacent organs is essential to achieve R0 resection. However, when the tumor invades the head of the pancreas or duodenum, R0 resection interferes with the lower resectability and results in a higher morbidity. Wereviewed these cases retrospectively and considered the proper extent of the surgical resection. Materials and Methods: We retrospectively analyzed cases where patients underwent surgery for gastric adenocarcinoma at the Department of Surgery, Presbyterian Medical Center, between January 1998 and December 2003. Among the 45 patients who were suspected to have pancreatic head or duodenum invasion by a primary tumor or metastatic lymph nodes based on the operative findings, we included 22 patients without incurable factors. The patients were classified into three groups: 4 patients that underwent a combined resection (PD group), 12 patients that underwent a palliative subtotal gastrectomy (STG group) and 6 patients that underwent bypass surgery only (GJ group). We analyzed the clinicopathological features, operative data and results. Results: The patients of the PD group achieved R0 resection by PD with D3 Dissection in all Patients. A pancreatic fistula was observed in one patient (morbidity 25%). There was no surgery-associated mortality (mortality 0%). All patients of the PD group were in stage IV. However, the 2-year survival rate (SR) was 75% and the 5-year SR was 50%. Six patients of the STG group underwent surgery with marginal resection and the other six patients of the STG group had a positive distal resection margin. The 2-year SR was 41.7% and the 5-year SR was 16.7%. Most of the patients of group GJ were of old age (mean age: $72.7{\pm}8.6$ years) or had chronic diseases. The 2-year SR was 0%. Conclusion: Combined resection of the pancreas and duodenum in AGC with pancreatic head invasion is relatively safe with moderate morbidity and a lower mortality. One can expect long-term survival if combined resectionis performed in cases without incurable factors.

Objective : Atypical and malignant meningiomas(AM, MM) are known to be rare and show aggressive behavior. Limited data are available concerning the clinical features, effectiveness of surgical removal and role of radiation therapy with AM, MM. The authors report our experience of AM, MM, with respect to clinical features. Methods : Twenty-four cases of AM and 28 cases of MM, who were operated between 1988 and 1999 were retro-spectively studied review of medical records and radiological findings. These were compared with control group of 24 cases of menigiomas manifestating usual clinical course, which are selected arbitrarily among operative cases between Apr. 1999 and Dec. 1999. Mean follow-up periods were 26(1-91) months for AM and 23(1-62) for MM. Authors analyzed the prognostic factors for survival, and statistical analysis were accomplished by Kaplan-Meier method and log-rank test. Results : Differences of clinical features between control groups and these atypical and malignant meningioma group were not significant. However, the location of MM was frequent in non-basal area(p<0.01). In AM, there were 4 patients of recurrence, and 3 patients of mortality. Among mortality cases, only one patient died of tumor progression, the other patients died of other causes. The survival at 2 year and 5 year in this group were 88% and 74% respectively, and in MM, 11 patients died due to tumor progression and 2 had spinal metastasis. The survival at 2 year and 5 year were 72% and 20%, respectively. For extent of resection, total removal(Simpson grade 1 or 2) was less often achieved in MM compared with AM(50% vs. 83%). Extent of resection of tumor and postoperative radiation therapy did not affect survival in both AM, MM. Conclusions : Clinical behavior of AM showed more benign than that of MM. Prognostic factor for survival is not related extent of resection of tumor and postoperative radiation therapy. However, further investigation with long-term follow-up and additional cases is mandatory.
As of today, the frequency of primary lung cancer is one of the improved problems in modern medicine and is increasing rapidly year by year. This study dealed with 138 cases of primary lung cancer proved by histopathologic examination in Thoracic & Card iovascular Surgery Dept. of N.M.C. from Sept. 1966 through June 1981. The majority of patients belong to 5th and 6th decade. Ratio between male and female was 3.7: 1. Initial symptoms were cough, blood tinged sputum, hemoptysis, chest pain, dyspnea and duration of symptoms before admission was within 6 months [60%] and 12 months [78%]. Histopathologically, 64 cases [61%] of them were the squamous cell carcinoma, 21 cases [15%] were the adenocarcinoma, 20 cases [14.8%] were the anaplastic carcinoma. Fifty-six cases were resectable: 43 cases were subjected to pneumonectomy and 13 cases were to lobectomy. The remaining 82 cases were nonresectable, but exploratory thoracotomy was performed in 22 cases of them. Among 56 resected cases, 33 cases were radically operated and 17 cases were subjected to palliative operation and 6 cases were subjected to extended operation. [Concomitant pericardium resection in 1 case and concomitant chest wall resection in 5 cases]. Surgical mortality was 10.7% and causes of death were aspiration of contralateral lung, respiratory insufficiency, postop. empyema with B.P.F, cardiogenic failure. This study analysed the cancer stage between preop clinical T.N.M. stage and postop. T.N.M. stage in 78 cases; resectable 56 cases and non-resectable 22 cases.
1. The purpose of this study is to provide a series of statistical "bench marks" from which one can begin to think systematically about the required development of the Korean food and fertilizer needs over the next quarter-century. 2. The Korean population has been estimated by the characteristics of the population and its social and political situations today. Because fertility and mortality rates are relatively stable and are under control of politics concerned, the estimation rates were established with 1.6% over 1975-1980, 1.3% over 1981-1990, and 1.0% over 1991-2000. 3. Annual per capita absorption of milled rice has fluctuated rather closely around 140kg, since 1968, with no evidence of declining trend. Per capita absorption of barley and wheat around 120 kg, and legumes around 10.6kg, However because the case of wheat and corn productions are rather difficult the self-sufficiency in the future, the rice is considered to be accelerate its yield growth surplus the level of self-sufficiency to export. 4. The fertilizer demand in each element has been calculated by mechanical multiplication of "the recommend index of fetilizer application" to yield a unit production over the need of national food supply by crop year. 5. As a results refer to Table (8), the estimated quantities of total fertilizer demand to meet the national food supply of the years of 1974, 1980, 1985, 1.990, 1995, and 2000 are reached around 871500, 1138150, 1375480, 1515030, 1652090 and 1799850 metric tons in each year.
This report describes our 10-year experience with intracardiac repair in 42 patients older than 16 year with tetralogy of Fallot. The mean age was 22.0$\pm$5.18 years[range 16~41]. The preoperative clinical manifestations were cyanosis & clubbing[93%], frequent URI [55%], anoxic spell[40%], pulmonary tuberculosis[21%], tuberculous empyema[7%], chronic renal failure[7%], congestive heart failure[7%] and subacute bacterial endocarditis [2%], etc. The previous shunt procedure for palliation had been performed in 7 patients. The type of VSD were typical perimembranous type[67%], total canal defect[28%] and combined type[5%]. The right ventricular outflow tract obstruction were combined type[69%], infundibular type[21%] and valvular type[10%]. Transannular patch was used in 50% of patients. Associated cardiovascular anomalies were ASD[33%], PFO[31%], Rt. aortic arch[10%], Lt. SVC[10%], single Rt. pulmonary artery, single Lt. coronary artery, ASI, proximal stenosis of Rt. pulmonary artery and anomalous systemic venous return, etc. Hospital mortality was 7.1%[3 cases]in overall. The causes of hospital deaths were revealed low cardiac output & acute renal failure[2 cases], postoperative bleeding[1 case]. There were 2 late deaths 3 & 68 months after surgery. Residual intracardiac shunt was detected in 2 patients. one patient was successfully reoperated and another patient had Qp /Qs ratio less than 1.5.
Background: The experience of a single-institution regarding surgery for small cell lung cancer (SCLC) was reviewed to evaluate the surgical outcomes and prognoses. Materials and Methods: From July 1990 to December 2009, thirty-four patients (28 male) underwent major pulmonary resection and lymph node dissection for SCLC. Lobectomy was performed in 24 patients, pneumonectomy in eight, bilobectomy in one, and segmentectomy in one. Surgical complications, mortality, the disease-free survival (DFS) rate, and the overall survival rate were analyzed retrospectively. Results: The median follow-up period was 26 months (range, 4 to 241 months), and there was one surgical mortality (2.9%). Six patients (17.6%) experienced recurrence, all of which were systemic. Eight patients died during follow-up; four died of disease progression and the other four died of pneumonia or of another non-cancerous cause. The three-year DFS rate was $79.2{\pm}2.6%$ and the overall survival rate was $66.4{\pm}10.5%$. Recurrence or death was significantly prevalent in the patients with lymph node metastasis (p=0.001) as well as in those who did not undergo adjuvant chemotherapy (p=0.008). The three-year survival rate was significantly greater in the patients with pathologic stage I/II cancer than in those with stage III cancer (84% vs. 13%, p=0.001). Conclusion: Major pulmonary resection for small cell lung cancer is feasible in selected patients. Patients with pathologic stage I or II disease showed an excellent survival rate after surgery and adjuvant treatment. Prospective randomized studies will be needed to define the role of surgery in early-stage small cell lung cancer.
