Total intravenous anesthesia(TIVA) is desirable technique for a number of reasons. The first is that it implies all the components of general anesthesia : hypnosis, amnesia, analgesia, and muscle relaxation by combination of several drugs and the lungs are ventilated with oxygen-enriched air. A combination of fentanyl-propofol were used as TIVA for laryngomicrosurgery (LMS) with high frequency jet ventilation(HFJV). 41 patients were studied. Glycopyrrolate was given 1 hour before anesthetic induction. Propofol 2 mg/kg was intravenously administered 1 minute after fentanyl 1.5 ug/kg intravenously injection for induction. Endotracheal intubation was performed after succinylcholine administration with internal diameter 4.0-6.0 mm LASER tube through oral cavity or 8 fr. polyethylene catheter through nasal airway. After then, HFJV was started with frequency 108-120 cycles/minute and driving pressure 2.0-2.5 kg/cm(2). The adequacy of ventilation was evaluated with arterial blood gas analysis. For maintenance a continuous propafol infusion of 10 mg/kg/hour was used for the first 10 minutes, followed by 8 mg/kg/hour for the next 10 minutes and 6 mg/kg/hour, thereafter. Continuous dripping of succinylcholine was used for muscle relaxation. The patients showed relatively stable hemodynamic status during procedure (Fig. 1). Two recovery times were as followed: the interval from cessation of infusion until opening eyes on command(4.90+/-3.41 min), and that until correct response to simple question (5.50+/-3.49 min). There was a correlation between total amount of propofol given to patients and recovery times(P<0.05)(Table 1). Interestingly. a group of patients weighed over 70 kg showed carbon dioxide retension on arterial blood gas analysis(Fig. 2). In conclusion, fentanyl-propofol cobination with muscle relaxant is proper regimen for TIVA in LMS with HFJV. More stable and better recovery are the main reasons. However, carbon dioxide retension should be consider to the patients weighed over 70 kg with the HFJV.

BACKGROUND: Though the surgical treatment of stage IIIB lung cancer is not generalized due to low complete remission rate high morbidity and mortality there are several reports on the improvement of long term survival after preoperative and postoperative adjuvant therapy. In this study we analyzed the prognostic factors affecting long term survival after surgical treatment of stage IIIB lung cancer MATERIAL AND METHOD: We analyzed the long term survival for age pathology invaded mediastinal organ n stage type of operation complete or incomplete resection and adjuvant therapy through a retrospective review of patients underwent surgical treatment. RESULT: From 1990 to 1998 56 patients(51/male 5/female0 with stage IIIB lung cancer were trated surgically. Forty two patients underwent radical resection and morbidity and mortality were 17% 12% respectively. The survival rate for overall patients and the radical resection group were 9% 12% respectively. In the radical resection group excluding explothoracotomy only(n=14) and the surgical mortality patients(n=5) the age the type of operation celly type resectability and N stage had no influence on the long term survival. The survival rate of radical resection group was significantly better than that of the explothoracotomy only group(p=0.04) The long term survival rate of postoperative combination therapy group was significantly better than chemotherapy or radiotherapy alone(p=0.04) CONCLUSION: Age type after surgical treatment of stage IIIB lung cancer. We conclude that combined modality of adjuvant treatment after radical resection of stage IIIB lung cancer seems to offer better long term survival in selective patients. The numbers of patients involved was small. Nevertheless these preliminary findings indicate questions that will need to be experienced further in larger studies.

BACKGROUND: Surgical resection is the standad therapy for the stage I lung cancer. We analysed the risk facturs of stage I lung cancer patent and tryed to establish more effective and aggressive treatment modality. MATERIALS AND METHODS: A detailed analysis was undertaken to evaluate the surgical results and to define the risk factors associated with the recurrence and the survival time in 146 consecutive patients with stage I lung cancer who were diagnosed, and resected at Yonsei Medical Center from January 1990 to December 1996. RESULTS: There were 115 males and 31 females. Their ages ranged from 27 to 79 years (mean age:58.9+/-9.3 years). The histologic types were squamous carcinoma in 72 cases (49.3%) and adenocarcinoma in 45 cases (30.8%). A pulmonary resection and mediastinal lymph node dissection were done in all cases. A lobectomy was performed in 96 cases (65.7%) and a pneumonectomy in 48 cases (32.9%). There were 5 operative mortalities (3.4%) and complications occured in 24 cases (16.5%). The overall 5-year survival was 64.1%, and survival time did not depend on the type of operation or histologic type. Significant predictors of decreased survival were visceral pleural invasion (p=0.0079), T2 lesion (p=0.0462), and tumor size (> or =5 cm) in adenocarcinoma (p=0.0472). The overall incidence of recurrence was 33.3% (47 cases; local or regional 6.4%, distant 26.9%). Almost all recurrences (44cases) occurred in T2 lesions. The distant organs that failed were the contralateral lung in 13 patients, the brain in 12, the bone in 10, and other organs in 3. CONCLUSIONS: even in stage I lung cancer, we suggest that postoperative adjuvant therapy is recommended in patients with poor prognostic factors such as visceral pleural invasion, T2 lesions, and a tumor size (> or =5 cm) in the adenocarcinoma.

BACKGROUND: The prognosis for young patients generally considered to be poor. The purpose of this study was to determined whether the clinical characteristics and the survival rate in young lung cancer patients after surgical treatment differs from that in older patients. MATERIAL AND METHOD: Of 526 patients, 28(5.3%) were 30 to 40 years old. We studied the clinical characteristics and prognosis of 28 patients aged 40 years or less(Group 1), in whom primary lung cancer was diagnosed and operated between 1990 and 1997, and compared them with those 498 patients aged more than 40 years(Group 2). RESULT: The differences in sex ratio that were higher for women in Group 1, but there was no significant difference (p=0.297). The percentages for smokers and symptoms in Group 1 were significantly less than in Group 2.(p=0.049, p=0.008). Adenocarcinoma was significantly more common (p=0.018) and squamous cell diagnosed was diagnosed as stage IIIb or stage IV in 9 patients(32.1%), while 12.0% of the patients older than 40 years of age had either stage IIIb or stage IV(p=0.002). The 5-year survival rate was 41.3% in Group 1 ; 37.7% in Group 2, and the median survival time was 24.3 months in Group 1 ; 27.0 months is Group 2. There were no significant difference in survival between two age groups(p=0.808). CONCLUSIONS: Younger patients have more adenocarcinoma, however have less squamous cell carcinoma, less symptoms and less smoking history. Although younger patients tended to have more advanced disease and less complete resection rate, the recurrence and the long term survival in these patients did not differ that of older patients.

OBJECTIVE: If bowels and other structures are in the pathway of high-intensity focused ultrasound (HIFU) beam during magnetic resonance image-guided HIFU (MRgFUS) therapy, filling to the bladder and the rectum and then emptying the bladder (i.e., the BRB technique) is used to avoid them. A modified BRB technique might be useful method to using a uterine elevator method or by inducing uterus downward traction to lower the position of the uterus. METHODS: A total of 156 patients who had undergone MRgFUS surgery treatment for uterine fibroids from March 2015 to February 2016 were included in this retrospective study. Of the 156 patients, 40 were treated using a uterine elevator while 29 were treated using downward traction of uterus. HIFU was performed using Philips Achieva 1.5 Tesla MR and Sonalleve HIFU system. RESULTS: MRgFUS surgery was feasible with modified BRB technique in 69 cases. Using uterine elevator method, the intensity of HIFU for group with antefletxio uteri was significantly lower than that for the group without antefletxio uteri (105.37±17.62 vs. 118.71±26.88 W). The group with downward traction of uterus induced was found to have significantly lower intensity of HIFU compared to the group without downward traction of uterus induced (110.26±22.60 vs. 130.51±27.81 W). CONCLUSION: Modified BRB technique was useful in avoiding bowels and other structures located in HIFU beam pathway during MRgFUS treatment to ablate uterine fibroids.

BACKGROUND: Surgery has been considered the most effective and standard treatment modality in non-small cell lung cancer(NSCLC). However in stage IIIA lung cancer, the role of surgery is still controversial. To evaluate the role of surgery for stage IIIA NSCLC, we investigated the survival after surgery and the prognostic factors. MATERIAL AND METHOD: We evaluated 158 consecutive cases of stage IIIA NSCLC patients operated on between 1990 and 1996. There were 130 male patients and 28 female patients, and the mean age was 58.5 years. All patients except one underwent lung resection beyond lobectomy and extended mediastinal dissection. Postoperative adjuvant therapy were undertaken in 145(94.8%) patients. All patients(153) were followed and the mean follow-up period was 21.4months. RESULT: Twenty nine cases of the postoperative complications developed in 25 patients (15.8%). There were 5 operative mortality cases(3.2%) and the main cause of death was acute respiratory distress syndrome (ARDS). Local or distant recurrences developed in 84 patients(54.9%). The 5-year survival of 153 patients was 29.6% and the median survival time was 18.0 months. The 5-year survival of non N2 disease group(36.8%) was better than that of N2 disease group(26.6%)(p=0.35) and the 5-year survival of squamous cell carcinoma (38.1%) was better than that of adenocarcinoma(25.7%)(p=0.39) however there were no significant differences. Regarding the postoperative adjuvant therapy, in combined therapy group(84 patients), radiotherapy group(37 patients) and chemotherapy group(24 patients), the 5-year survival were 31.3%, 32.4%, and 14.6% respectively. There was no difference of survival between radiotherapy and combined therapy group(p=0.31), however the survival of the combined therapy group was better than the chemotherapy group(p=0.005). The survival of the complete resection group(31.9%) was better than the incomplete resection group(16.6%) however there was no significant difference(p=0.19). CONCLUSION: These observations indicate that the good 5-year survival(29.6%) in patients with stage IIIA NSCLC result from the agressive surgical treatment including extensive mediastinal nodes dissection.

BACKGROUND: Many institutes are interested in lung metastatectomy than before because of the improved long term survival, low mortality, and low morbidity after lung metastatectomy. However, prognostic factors affecting long term survival are controversial. We attempt to analyze the prognostic factors affecting retrospectively by comparing the results of lung metastasectomy. MATERIAL AND METHOD: Between Jan. 1990 and Dec. 1997, 74 operations were taken in 63 patients with pulmonary metastases in various primary sites. We analyzed the postoperative long term survival according to sex, cell type, laterality, disease free interval(DFI), operation, the number of metastases, and the size of the largest metastasis. RESULT: There were 27 male and 36 female patients. Sex did not appeared to affect survival time(p=0.849). The primary tumor was carcinoma in 32, sarcoma in 28, and others in 3. Cell type, considering carcinoma and sarcoma, did not relate to survival time(p=0.071). DFI had no influence on the outcome(p=0.902). The type of operative procedure had no influence on the outcome(p=0.556). The laterality of metastases, 47 unilateral(74.6%) and 16 bilateral(25.4%), had no influence on the outcome(p=0.843). The number of metastases excised(one, two or three, four or more) did not appear to affect survival(p=0.263). The size of largest metastasis(<=10mm, 11mm-30mm, and >30mm) did not appear to affect survival(p=0.751). Previous factors were evaluated in both the carcinoma and sarcoma patients respectively. DFI was the only significant prognostic factor in metastatic lung sarcoma(p=0.0026). CONCLUSION: Survival was not related to sex, cell type, laterality, DFI, operative procedure, number of metastases, nor the size of the largest metastasis. DFI was related to the survival time in sarcoma group but further study is needed.

Bafckground: Thr role and indication of surgery in the treatment of small cell lung cancer (SCLC) is currently limited and unsettled. MATERIAL AND METHOD: We analyzed the surgical results of 9 patients with SCLC at Yosei Medical Center from January 1990 to December 1996. There were 8 males and 1 female, and their mean age was 57.2 years (range; 35-76). Preoperatively SCLC was confirmed in 5, but the other 4 cases were diagnosed as undifferentiated squamous cell carcinoma. All patients underwent pulmoinary resection (lobectomy;5, lobectomy, segmentectomy and en-bloc resection of rib;1, bilobectomy; 2, pneumonectomy;1) and mediastinal lymph node dissection. RESULTS: There were no operative mortality with two complications (postoperative bleeding;1, arrhythmia;1). All cases were diagnosed as SCLC histologically and their TNM staging were confirmed as follows: T1N0M0;1, T2N0M0;4, T3N0M0;1, T3N1M0;1, T2N2M0; 1, T4N0M0;1. All patients had received postoperative chemotherapy, and radiotherapy was combined in 4 patients. During follow up period (range 1-63 months; mean 33.0months), there was only one metastasis to pelvic bone among 8 patients without lymph node metastasis, and all patients were alive. On the other hand, among 3 patients who had regional and/or mediastinal lymph node metastasis or T4 lesion, all patients had recurrences (local;2, brain;1), and 2 patients died. CONCLUSION: We suggest that the use of TNM staging is beneficial, and surgical resection should be recommended in the patients with early staged SCLC as an important treatment modality.

OBJECTIVE: This study was performed to assess our clinical experience with single-port access (SPA) laparoscopic cystectomy and myomectomy and the surgical outcomes of those procedures at our institution. METHODS: The authors evaluated the surgical outcomes of SPA laparoscopic cystectomy in 293 patients and SPA laparoscopic myomectomy in 246 patients. The surgical outcomes comprised operation time, the amount of blood loss during the operation, the change in hemoglobin (before and after the operation), the change in hematocrit (before and after the operation), switching to the multi-port access method, complications, transfusions, and the duration of the postoperative hospital stay. RESULTS: The Pearson correlation coefficient and the Spearman correlation coefficient between the operation time and the amount of blood loss were 0.312 and 0.321 for SPA laparoscopic cystectomy, respectively, and 0.706 and 0.674 for SPA laparoscopic myomectomy, respectively. The drops in hemoglobin and hematocrit were 1.33~0.78 g/dL and 4.14%~2.45%, respectively, in SPA laparoscopic cystectomy, while the corresponding figures were 1.34~1.13 g/dL and 4.17%~3.24% in SPA laparoscopic myomectomy, respectively. CONCLUSION: This study reported the surgical outcomes of SPA laparoscopic cystectomy and myomectomy and compared them to previously published findings on traditional laparoscopic cystectomy and myomectomy. No significant differences were found in the surgical outcomes between SPA and traditional laparoscopic cystectomy and myomectomy.

Carcinomas of the lung, breast and lymphoma account for approximately 75% of malignant pleural effusions and the metastatic ovarian carcinoma is the fourth leading cause of malignant pleural effusions. The diagnosis of a malignant pleural effusion is established by demonstrating malignant cells in the pleural fluid or in the pleural biopsy. Chemical pleurodesis should be considered in cases of patients with malignant pleural effusion, who were not responded with systemic chemotherapy. We experienced a case of malignant pleural effusion treated by chemical pleurodesis, which was developed in a patient with ovarian carcinoma and we report it with the brief review or literatures.
