Objectives . This study was conducted in order to investigate the degree of recognition, acceptability, and altitude towards day surgery of patients who were hospitalized with diseases that were candidates for day surgery; in order to analyze the average length of stay for treatment of the ailments; and to analyze the percentage of patients who could be discharged on the same day after the surgery ,using the post-anesthesia discharge scoring system. Methods : Data was collected between February 1 and March 31, 1999 from 353 patients who received surgery for cataract, adenoid hypertrophy, inguinal hernia, strabismus, ptosis, cholelithiasis, hemorrhoid, or anal fistula, at a general hospital in Daegu city. The patients were interviewed and surveyed by a post-anesthesia discharge scoring system(PADS) in order to collect data on patient condition such as vital signs, activity and mental status, pain, nausea and vomiting, surgical bleeding, intake and output after the surgery. Results : Among the 353 patients, 52.7% were after of the day surgery and 52.7% were interested in day surgery. Of the respondents, 43.1% said 'my ailment was not serious and the surgery was simple' and 30.4% said 'according to my condition rest at home was desirable' as the reasons for wanting day surgery Alternatively, 56.5% of those declining day surgery said the 'uncertainty of staying home' was the reason. The greatest concern in discharging within 24 hours after surgery was a post-op emergency situation. On the other hand, the shortened hospitalization was the largest advantage of day surgery with 39.1% responding this way, followed by the savings in hospitalization costs (25.8%) and emotional stability (13.7%). The majority of those surveyed (47.6%) believed that discharge should be determined within 1-2 days after the surgery. The average hospital stay was 3.1 days for dischargeable ailments. Pain (45.6%), nausea and vomiting (10.5%), and headache (7.9%) were the common symptoms following surgery. The percentage of patients who were able to be discharged within 24 hours after surgery revealed 95.2% were dischargeable after approximately 3 hours, 99.2% dischargeable after 12 hours, and 100% dischargeable after 24 hours. Conclusions : According to the PADS score, the cataract extract and strabismus correction patients were eligible for day surgery and the further evaluation concerning the reason for delayed recovery of the other diseases is needed.

Purpose: We have preoperatively and postoperatively investigated the characteristics of anemia in patients with gastric cancer in order to provide optimal medical care for the patients. Materials and Methods: Preoperative hemoglobin, serum iron, serum ferritin, serum vitamin $B_{12}$, and serum folic acid were measured for 321 patients with gastric cancer. These were measured again for 287 patients 6 months postoperatively. Results: Ninety-four patients (29.3%) had preoperative anemia. Preoperative hemoglobin, serum iron, and serum vitamin $B_{12}$ levels were higher in the patients with early gastric cancer than in patients with advanced gastric cancer. Preoperative hemoglobin, serum iron, and serum ferritin levels were higher in male patients than in female patients. The patients who had preoperative anemia showed a high probability of having postoperative anemia (P<0.001), and the patients who had low serum ferritin levels preoperatively showed a high probability of having low serum ferritin levels and iron deficiency anemia postoperatively (P<0.004). Conclusion: Preoperative ferritin deficiency should be improved by iron supplement, even though the patient may not be anemic at that time. Periodic postoperative measurements of the hemoglobin, serum iron, serum ferritin, serum vitamin $B_{12}$, and serum folic acid levels are highly recommended because postgastrectomy anemia is not rare. Finally, if any low hemoglobin, serum iron, serum ferritin, serum vitamin $B_{12}$, or serum folic acid levels are found, they should be treated in an appropriate way.

Background: Postoperative pulmonary complications are important problems that prolong the length of the hospital stay and increase patient mortality. However, our knowledge of the postoperative factors that increase the risk of these complications is less than complete. Methods: We conducted a prospective study to determine the risk factors for postoperative pulmonary complications. A total of 199 patients were referred to the Pulmonology Department for preoperative pulmonary evaluation. We reviewed the perioperative variables according to the National Surgical Quality Improvement Program (NSQIP). Postoperatively, we collected data on the occurrence of postoperative pulmonary complications and we evaluated the relationship between the perioperative variables and outcomes. Results: Twenty two patients (11%) had pulmonary complications; 6 had respiratory failure, 4 had pneumonia, 13 had pleural effusion and, 2 had atelectasis. Five variables were statistically significantly associated with pulmonary complications on the bivariate analyses. Multiple logistic regression analyses revealed that three of these variables were independently associated with an increased risk of pulmonary complications; a high cardiac risk index (OR 16.5, p=0.002), emergency surgery (OR 10.3, p=0.017), and thoracic/abdominal surgery (OR 3.8, p=0.047). Conclusion: The risk factors for postoperative pulmonary complications are a high cardiac risk index, emergency surgery and thoracic/abdominal surgery.

Background: After general anesthesia, decrease of functional residual capacity and lung compliance, ventilation/perfusion imbalance, and transpulmonary shunting can provoke hypoxemia during postoperative periods. Diaphragmatic dysfunction may be the main cause of these physiological abnormalities. Thus, we evaluated the change of pulmonary function after general anesthesia according to the operative sites, which could suggest clinical course and critical period of respiratory care of postoperative patients. Method: Preoperative portable spirometric evaluation and arterial blood gas analysis were performed at sitting or most-sitting position just previous day of surgery. Pulmonary function tests were also as same condition from postoperative day 1 to day 5. Results: 1) For thoracic surgery, FEV1 and FVC were not recovered at day 5, but FEV1/FVC was not decreased. $PaCO_2$ was slightly elevated at postoperative one day. 2) After upper abdominal surgery, postoperative day 5 did not show the recovery of FEV1 and FVC, but mild hypoxemia was developed at postoperative day 1. 3) Pulmonary function was recovered as preoperative value at postoperative day 5 in lower abdominal operation, but mild hypoxemia was also noted at postoperative day 1. 4) Surgery of peripheral areas did not show significant pulmonary function change and hypoxemia and hypercapnia from postoperative day 1. Conclusion: Surgery involving diaphragm provoke significant postoperative pulmonary function change after day 5. For the operation of peripheral sites adequate respiratory care during operation and postoperative period within 24 hours could prevent patients from respiratory complication.

구강과 구인두에서 발생되는 유표피암은 전체 예수병원 암환자의 3.9%를 차지한다. 만 20 년 간의 월발성 유표피암 환자 5%명에 대한 고찰결과, 혀 전방 2/3 에서 29%로써 가장 높은 발생빈도를 보였으며 faucial arch, base of tongue 및 tonsil을 포함한 구 인두는 28%의 발생빈도를 나타냈다. 그외는 잇몸, 구강저, 구순, 구개 (palate) 및 구강내 점막의 빈도순이었다. 환자 중 153 명 만이 근치적 치료를 받았다. 1974 년 이전에는 치료 정책에 수술만이 활용되었던 까닭으로 역행성 분석결과 74 명에서는 수술만 시행케 되었으나, 그 이후의 70 명에서는 종합적치료를 시행하였으며 그중 9 명은 확실한 방사선요법을 받았다. COMMANDO 수술과 복합절제술 (Composite resection) 을 시행했던 환자들의 비교검토는 매우 의의가 있었다. 수술만 받은 환자와 비교해 볼때, 수술후 방사선요법을 병행했던 수술환자의 경우에 있어서 재발율은, Stage III 에서는 50%에서 41%로, Stage IV 는 79%에서 68%로 각각 감소를 보였다. 또한, COMMANDO 수술 경우만 국한시켜 비교할 때는 수술만 받은 환자와 비교할 때 수술후 방사선치료를 받은 환자와 비교하여 2 년간 무병율 (disease free interval) 이 수술후 방사선요법을 병행함으로써 17.3%에서 29.3%로 증가됨을 알 수 있었다.

Background: The detection of circulating microemboli by transcranial Doppler ultrasonography (TCD) has the potential to select the patients with high risk for future symptomatic brain embolism. We prospectively evaluated the positive rate and the frequency of microembolic signals (MES) before and after the heart valve surgery (HVS). Material and Method: Fifty in-patients with heart valve disease were enrolled in this study. Patients with history of previous stroke or heart valve surgery were excluded. Two unilateral TCD monitoring sessions were peformed from middle cerebral artery for 1-hour, before and after HVS. Result: Mechanical Heart valves were implanted in 28 patients, tissue valves were implanted in 10 patients, and remaining 12 patients received mitral valve repair. Positive rate of MES was significantly increased after HVS (50%), compared to that of before HVS (8%, p=0.00). There was no relation between MES after HVS and intensity of anticoagulation, cardiac rhythm, patients' age, and history of hypertension. The positive rate of MES after implantation of mechanical heart valve (71.4%) was significantly higher than those after implantation of tissue valve or mitral valve plasty (p=0.002). Conclusion: Positive rate of MES was increased significantly after the implantation of HVS. The changes of MES in those with mechanical prosthesis may be related to the increased risk or embolism after Hvs.

Purpose : Rarity of olfactory neuroblastoma makes it difficult for treating Physician to Practice with a consistent protocol. This study is peformed to analyze our experience with various treatment modalities for patients with olfactory neuroblastoma. Discussion includes review of some recently published literatures. Methods and Materials : Between June of 1979 and April of 1997, 20 patients were treated under the diagnosis of olfactory neuroblastoma at Seoul National University Hospital. There were 14 male and 6 female patients. Age at initial treatment ranged from l3 to 77 years with median or 24 years. fifteen or 20 patients had Kadish stage C. They were treated with various combinations of surgery, radiation therapy and chemotherapy; surgery+postoperative radiation therapy+adjuvant chemotherapy for 2 patients, surgery+postoperative radiation therapy for 6, neoadjuvant chemotherapy+surgery for 1, surgery+adjuvant chemotherapy for 1, surgery only for 2, neoadiuvant chemotherapy+ radiation therapy for 3, radiation therapy+adjuvant chemotherapy for 1, radiation therapy only for 3, and no treatment for 1 patient. Results : Follow-up ranged from 2 month to 204 months with mean of 39.6 months. The overall 5- and 10-year survival rates are 20% and 10%, respectably. Four patients are alive at the time of data analysis. One of four living patients was treated with radical surgery, postoperative radiation therapy and adjuvant chemotherapy, two patients with radical surgery and postoperative radiation therapy, and one with radical surgery only. Conclusion : Multidisciplinary approach, including radical surgery, pre- or post-operative radiation therapy and chemotherapy, should be addressed at the initial time of diagnosis. Although limited by small number of the patients, this study suggests importance of local treatment modality, especially radical surgery in the treatment of lofactory neuroblastoma.
