후두암의 치료는 병변의 위치, 크기 등에 따라 치료방법이 다양하고 그 예후 또한 상이하다. 일반적으로 초기 후두암에서는 수술이나 방사선 요법이 비슷한 치료결과를 보이고, 진행된 후두암에서는 수술적 치료가 더 좋은 예후를 나타내는 것으로 알려져 있으나 발성장애를 초래하는 경우가 대부분이다. 저자들은 1986년부터 1990년까지 5년간 강남성모병원에서 후두암치료를 받았던 환자 81명을 대상으로 치료방법에 따른 음성보존 성적을 분석하였다. 1. T1 성대암 환자 18명중 16명 (88.9%)에서 방사선치료 또는 수술로써 음성을 보존할 수 있었다. 2. T2 후두암 환자 11명중 6명은 수술후 음성보존이 가능하였다. 3. 진행암환자 (T3, T4) 50명중 33명에 대해 수술을 시행하였고 이중 16명(48.5%)은 후두부분 또는 근전적출술 및 기관-식도 누공술에 의해 음성기능을 보존할 수 있었다. 4. 진행암환자에서 유도화학요법과 방사선치료의 병용요법만을 받은 17명 모두 6개월 이내에 재발하였고, 수술 혹은 수술과 방사선 치료를 병용한 33명중 27명이 최소한 6개월 이상 평균 2년 이상의 무병상태였다. 5. 후두부분 또는 근전적출술은 총 81명중 28명에서 시행되었고 그중 5명 (17.9%)에서 재발하였다.

배경: 일반적으로 다제내성 폐결핵의 경우 화학요법만으로는 치료성적이 만족스럽지 못하였다. 이에 수술적 치료와 항결핵 화학요법의 병합사용이 높은 균음전율과 장기 생존율을 보여주고 있으므로 이러한 치료전략이 다제내성 폐결핵환자의 일반적인 치료방법으로 정립되리라는 전망을 갖게 하고 있다. 대상 및 방법: 1995년 1월부터 1999년 12월까지 국립마산결핵병원에서 폐결핵에 대한 수술을 시행받은 130례 중 다제내성 폐결핵으로 폐절제수술을 받은 49례를 대상으로 의무기록 및 검사기록 등을 근거로 후향적 조사를 실시하였다. 결과: 대상환자들의 평균연령은 35세였고, 내성약제의 수는 평균 4.5였다. 43례(87.8%)의 환자에서 공동성 병소를 보였으며 31례(63.3%)의 환자에서 술전 객담내 균양성 소견을 보였다. 수술술식은 12례에서 전폐적출술을, 28례에서 폐엽절제술을, 7례에서는 폐엽절제술과 구역절제술 혹은 설상절제술 등을, 그리고 설상절제술과 공동성형술을 각각 1례에서 시행하였다. 술후 지속적인 내과적 약물치료를 병합하여 장기적인 균음전율은 93.5%였고 술후 사망환자는 없었다. 술후 합병증으로는 1주일 이상 지속되는 공기유출 6례와 술후 출혈, 창상분열이 각각 1례씩 있었다. 결론: 다제내성 폐결핵환자에서 폐절제 수술에 대해서는 적절한 적응증, 수술후 처방, 그리고 술후 치료기간 등에 대한 이견이 있지만 적극적으로 고려되어야 하며 술후 내과적 치료와 병행함으로 좋은 치료효과를 얻을 수 있었다.

Purpose: The purpose of this study is to determine whether it is possible to evaluate patients with pN2 or pN3 early gastric cancer (EGC) as being in an advanced stage before and during the operation. Materials and Methods: 4,430 patients underwent a gastrectomy for cancer from 1990 to 2003. Eight of the 552 patients with EGC included pN2 or pN3. The estimated clinical and surgical stage before and during the operation were compared to the pathological results, and a follow-up of progression was done. Results: The patients were evenly distributed among all age groups with seven men and one woman. The pre-operative estimate of T1 by CT was 25% (2/8). In the main, the cT stage was over estimated. The estimate of over N2 was 50% (4/8). One patient was preoperatively staged as la sT1 during operation was 57.1% (4/7), and the estimate of over N2 was 67% (4/6). Two patients were intraoperatively evaluated as Ia. Only one patient survived over 5 years, and the mean survival of these patients was 15 months $(95%\;Cl:\;0{\sim}35.5)$. Conclusion: It was generally possible to evaluate patients with EGC of over pN2 as being in an advanced stage before and during the operation. Although very rare (2/552, 0.04%), there were EGC patients whose stages were not predictable at all. Therefore, more precise preoperative and intraoperative staging methods are warranted.

Despite early aggressive treatment, post myocardial infarction(MI) ventricular septal defect(VSD) revealed high surgical mortality. We reviewed the 10-year experiences of surgically treated post-MI VSD in Yonsei University. Material and Method: From Jan. 1991 to May 2001, 17 patients underwent surgical repair of post-MI VSD. Ages ranged between 47 and 77 years(mean age＝63.2$\pm$9.1). There were 10 males and 7 females. VSD was located at anterior in 16 patients and at posterior in one. IABP was inserted preoperatively in 12 patients due to cardiogenic shock. Mean interval from MI to occurrence of VSD was 5.6 days. Among patients undergoing early surgical correction(n＝13), mean interval from occurrence of VSD to operation was 2.5 days. In 11 patients, concomitant CABG was performed during repair of VSD. Result: Four patients died within 30 days after the operation(30 day mortality＝23.5%). Among 12 patients with preoperative cardiogenic shock, 4 patients died within 30 days(30-day mortality＝33.3%). During mean follow up period of 52 months, one patient died of unknown cause and 10-year survival of discharged patients was 66.7%. All follow-up patients were in NYHA functional class I or II when their last OPD visit. Conclusion: In the treatment of post-MI VSD, aggressive medical treatment with early surgical correction seems to be very important in terms early and long-term survival of patients.

Background: Surgical resection is the only way to cure non-small cell lung cancer(NSCLC) and the prognosis of NSCLC in patients who undergo a complete resection is largely influenced by the pathologic stage. After surgical resection, recurrences in distant sites is more common than local recurrences. An effective postoperative adjuvant therapy which can prevent recurrences is necessary to improve long tenn survival Although chemotherapy and radiotherapy are still the mainstay in adjuvant therapy, the benefits of such therapies are still controversial. We initiated this retrospective study to evaluate the effects of adjuvant therapies and analyze the prognostic factors for survival after curative resection. Method: From 1990 to 1995, curative resection was perfomled in 282 NSCLC patients with stage I, II, IIIa, Survival analysis of 282 patients was perfonned by Kaplan-Meier method. The prognostic factors, affecting survival of patients were analyzed by Cox regression model. Results: Squamous cell carcinoma was present in 166 patients(59%) ; adenocarcinoma in 86 pmients(30%) ; adenosquamous carcinoma in II parients(3.9%); and large cell undifferentiated carcinoma in 19 patients(7.1%). By TNM staging system, 93 patients were in stage I; 58 patients in stage II ; and 131 patients in stage rna. There were 139 postoperative recurrences which include 28 local and 111 distant failures(20.1% vs 79.9%). The five year survival rate was 50.1% in stage I ; 31.3% in stage II ; and 24.1% in stage IIIa(p <0.0001). The median survival duration was 55 months in stage I ; 27 months in stage II ; and 16 months in stage rna. Among 131 patients with stage rna, the median survival duration was 19 months for 81 patients who received postoperative adjuvant chemotherapy only or cherne-radiotherapy and 14 months for the other 50 patients who received surgery only or surgery with adjuvant radiotherapy(p=0.2982). Among 131 patients with stage IIIa, the median disease free survival duration was 16 months for 21 patients who received postop. adjuvant chemotherapy only and 4 months for 11 patients who received surgery only(p=0.0494). In 131 patients with stage IIIa, 92 cases were in N2 stage. The five year survival rate of the 92 patients with N2 was 25% and their median survival duration was 15 months. The median survival duration in patients with N2 stage was 18 months for those 62 patients who received adjuvant chemotherapy and 14 months for the other 30 patients who did not(p=0.3988). The median survival duration was 16 months for those 66 patients who received irradiation and 14 months for the other 26 patients who did not(p=0.6588). We performed multivariate analysis to identify the factors affecting prognosis after complete surgical resection, using the Cox multiple regression model. Only age(p=0.0093) and the pathologic stage(p<0.0001) were significam prognostic indicators. Conclusion: The age and pathologic stage of the NSCLC parients are the significant prognostic factors in our study. Disease free survival duration was prolonged with statistical significance in patients who received postoperative adjuvant chemotherapy but overall survival duration was not affected according to adjuvant therapy after surgical resection.

Objective : Paraclinoidal aneurysms termed that aneurysms arising from proximal internal carotid artery(ICA) between the site of emergence of the carotid artery from roof of the cavernous sinus and origin of the posterior communicating artery(PCoA). These aneurysms pose conceptual and technical surgical problems with regard to acquisition of proximal control and safe intracranial exposure. The efficiency of surgical technique according to the location of paraclinoidal aneurysm was studied for minimal exposure. Materials and Methods : Over the past four years, the authors treated surgically 171 cases of cerebral aneurysm, among them ten patients were paraclinoidal aneurysms with two patients unruptured aneurysms. Mean age was 47 years old, and all patients were female. Three patients were proximal posterior carotid artery wall aneurysms(one large, one giant), four patients carotid-ophthalmic artery aneurysms and three patients superior hypophyseal artery aneurysms. Results : There could be done clip in all cases, there were no deaths and no complication. And no patient developed sustained neurological deficits including visual function except hydrocephalus in one case. Four patients complained of visual disturbance but two patients had recovery after postoperation and two patient were not longer to bad. Conclusion : Our recent experience suggests that preoperative scrutiny of diagnostic angiography allows classification of all paraclinoidal aneurysms regardless of size and surgical technique which this classification has focused on operative approaches unique to each aneurysm projection was helpful to improve the operative outcome with good visual function and to shorten the operative time.

Objective : To determine the role of preoperative embolization on postoperative neurological outcome in the treatment of cerebral AVMs, we retrospectively evaluated an effectiveness of combining preoperative embolization and microsurgery for arteriovenous malformations(AVM) of the brain. Method : Two groups(10 patients who underwent preoperative superselective embolization and surgery versus 27 patients who underwent surgery only) were compared and categorized by Spetzler-Martin grade, the size of AVM and postoperative clinical outcome using Glasgow Outcome Scale. The 37 patients included 23 males and 14 females, ranging in age from 11 to 74 years(mean 36 years). Results : The arteriovenous malformations in preoperative embolization and surgery group had a larger average greatest diameter(4.45cm versus 3.83cm) and were of higher Spetzler-Martin grade(80% versus 52% grade III through V). At 1 week after surgery, the preoperative embolization and surgery group represented a better outcome(60% versus 44% with Glasgow Outcome Scale score of 5). And over 6 months after surgery, the embolization and surgery group displayed more favorable clinical outcome(80% versus 63% with Glasgow Outcome Scale score of 5). Conclusion : Combined treatment with superselective preoperative embolization using N-butyl cyanoacrylate and direct surgery may help neurosurgeon treating the high grade AVMs thus improving the postsurgical outcome.

This study was attempted to identify the factors relating to the medical service satisfaction on the patients utilizing a day-case surgery center in Korea. A questionnaire survey was conducted to patients were utilizing a day-surgery center, independently operated by one general hospital from January 13 to February 13, 2009. The results of this study can be summarized as follows. First, in the characteristic related with health and medical situations, day-surgery patients had little experience with surgery or hospitalizing and much interest in their health. Secondly, there were significant differences in regard to the quality of medical service for surgery waiting time and surgery time(p<0.05). Thirdly, multiple regression analysis revealed that age and level of education affected patients perception of day surgery(p<0.05). In conclusion, in order to increase the rate of day-surgery, it is necessary to give information about the advantages of day-surgery center and preoperative education.

This study aimed to investigate the awareness and performance of safety in operating room nurses. There were 161 operating room nurses from eight general hospitals included for analysis in this study. The data were analyzed with t-test, one-way ANOVA, correlation analysis, and Scheffe's test. The results show that their perception of patient safety was 3.33 out of a total of 5 points. Moreover, the score of safety management activity for patients in the operating room was 4.28 out of 5 points. As the perception of patient safety in operating room nurses was significantly correlated with their safety management activities, nurses with higher awareness of patient safety were found to have higher degree of performance of safety management activities. In conclusion, to improve safety management activities, open discussion about patient safety should be encouraged and periodic education regarding patient safety should be implemented for operating room nurses to increase the perception of patient safety.
