Staple closure of bronchial stump was compared with manual suture closure among 100 cases of pneumonectomy during the recent 5-year period, We have reviewed the incidence of bronchpleural fistula between autosutured group and manual sutured group. Material and Method: During the recent 5-year period, 100 patients underwent pneumonectomy at Hanyang University Hospital. Staple closure of bronchial stump was performed in 65 patients and manual suture in 35 patients. There were 55 males and 10 females in the autosutured group, and 26 males and 9 females in manual sutured group, which showed no significant statistical difference between the two groups. The mean ages of patients for autosutured group and manual sutured group were 56.7$\pm$10.3 years and 61.4$\pm$9.2 years, respectively, which showed no significant statistical difference between the two groups. There were 38 cases of left pneumonectomy and 27 cases of right pneumonectomy in autosutured group, and 22 cases of left pneumonectomy and 13 cases of right pneumonectomy in manual sutured group. There were 53 cases of malignancy and 12 cases of benign imflammatory disease in autosutured group, and 27 cases of malignancy and 7 cases of benign imflammatory disease in manual sutured group. Result: The incidence of bronchopleural fistula was 6.1% in autosutured group and 5.7% in manual sutured group. The incidence of other postoperative complication between the two groups showed no significant statistical difference. Conclusion: The incidence of bronchopleural fistula between autosutured group and manual sutured group was not different stastically. Both method for closure of bronchial stump can be performed in pneumonectomy.

Background: It has been known that see antigen was used in diagnosis of uterine cervical cancer and also known to be higher in squamous cell lung cancer. There has been no report about see antigen in squamous cell lung cancer in Korea. This study was designed to evaluate the usefulness of see antigen as a diagnostic tool and index for follow up after treatment. Method: The serum level of see antigen was measured in 12 cases with squamous cell lung carcinoma, 9 patients with other types of lung cancer, 7 patients with benign lung disease and 7 normal subjects by radioimmunoassay with Abott see Riabeap radioimmunoassay kit. We also measured see antigen after treatment in 6 patients who had received chemotherapy or sugery. Result: 1) The level of see antigen ($mean{\pm}1$ SD) was $2.27{\pm}1.53$, $0.67{\pm}0.38$, $0.62{\pm}0.53$, $0.53{\pm}0.36\;ng/ml$ respectively. 2) The see antigen activity in squamous cell lung carcinoma according to stage were as gollows. I; $2.07{\pm}1.56$, $III_a$; $5.04{\pm}0.53$$III_b$; $1.94{\pm}0.7$ IV; $1.07{\pm}0.64$ (ng/ml). 3) In squamous cell lung cancer, 5 of 12 (42%) cases was shown more than 2.0 ng/ml see antigen. (sensitivity; 42%), but there was no case in any other type of lung cancer, benign lung disease, and in control groups (specificity; 100%). 4) The serum sec antigen level after treatment was significantly decreased in patients with partial or complete remission (p<0.01). Conclusion; It was suggested that see antigen might be used as a useful tumor marker for the response of treatment and assessment of prognosis in squamous cell lung cancer, but further study should be performed for the clinical use of see antigen.
Background: There have been several reports using animal experiments that CD1-restricted T-cells have a key role in tumor immunity. To address this issue, we studied the expression of markers for CD1c+ myeloid dendritic cells (DCs) isolated from peripheral blood in the clinical setting. Material and Method: A total of 24 patients with radiologically suspected or histologically confirmed lung cancer who underwent pulmonary resection were enrolled in this study. The patients were divided according to histology findings into three groups: primary adenocarcinoma of lung (PACL), primary squamous cell carcinoma of lung (PSqCL) and benign lung disease (BLD). We obtained 20 mL of peripheral venous blood from patients using heparin-coated syringes. Using flow-cytometry after labeling with monoclonal antibodies, data acquisition and analysis were done. Result: The ratio of CD1c+CD19- dendritic cells to CD1c+ dendritic cells were not significantly different between the three groups. CD40 (p=0.171), CD86 (p=0.037) and HLA-DR (p=0.036) were less expressed in the PACL than the BLD group. Expression of CD40 (p=0.319), CD86 (p=0.036) and HLA-DR (p=0.085) were less expressed in the PACL than the PSqCL group, but the differences were only significant for CD86. Expression of co-stimulatory markers was not different between the PSqCL and BLD groups. Expression of markers for activated DCs were dramatically lower in the PACL group than in groups with other histology (CD40 (p=0.005), CD86 (p=0.013) HLA-DR (p=0.004). Conclusion: These results suggest the possibility that CD1c+ myeloid DCs participate in control of the tumor immunity system and that low expression of markers results in lack of an immune response triggered by dendritic cells in adenocarcinoma of the lung.

Objectives and Methods : The presence of aneuploidy or high proliferative activity in cytologic specimens is considered as complementary for the diagnosis of malignancy. To evaluate the diagnostic usefulness of DNA ploidy and cell cycle analysis in lung cancer, we compared the diagnostic yielding rates of DNA ploidy test by brushing specimens using flow cytometry with bronchoscopic forceps biopsy and brushing cytology. Results : Of the seventy-six cases, 55 cases proved to have malignant diseases(squamous cell cancer: 27, adenocarcinoma: 7, large cell cancer: 1, undifferentiated: 4 and small cell cancer: 16). The incidence of aneuploidy in lung cancer patients was 32.7%(18/55), as opposed to no cases in benign disease. And the proportion of high proliferative activity(S+G2M>22%) in lung cancer patients was 42.9%(15/35), but none in benign diseases. In fifty-six of 75 cases(74.7%), cytology of brushing specimens and DNA analysis(either aneuploidy or high proliferative activity vs. diploidy and low proliferative activity) were in concordance. The sensitivity with only brushing cytology was 41.8%(23/55), but with the addition of DNA analysis, it was increased to 56.4%(31/55), without decreasing the specificity(100%). And there was a case whose clue for malignancy was absent except aneuploidy, and he was confirmed to have squamous cell cancer following open thoracotomy. There were no differences in the frequency of aneuploidy or high proliferative activity between histologic subtypes of bronchogenic malignancy. Conclusions : The diagnostic detection rate of lung cancer was improved with the addition of DNA ploidy and cell cycle analysis, and the presence of aneuploidy or high proliferative activity was a relatively specific indicator of malignant disease. It would be useful to test DNA ploidy and cell cycle analysis with brushing specimen for the diagnosis of bronchogenic malignancy particularly in patients whose biopsy specimen could not be obtainable.
Background: We analyzed our experience of arrhythmia surgery in patients with congenital heart disease. Material and Method: A retrospective review was performed on 43 consecutive patients with congenital heart disease, who underwent arrhythmia surgery between June 1998 and June 2006. Result: The median age at surgery was 52 years ($4{\sim}75$ years). The most frequent cardiac anomaly was an atrial septal defect (23/43, 53.5%). The types of arrhythmias were atrial flutter-fibrillation, intermittent non-sustainable ventricular tachycardia and others in 37, 2 and 4, respectively. Arrhythmia surgery consisted of a bi-atrial maze operation in 18 patients (modified cox maze III procedure in 5 patients, and a right side maze plus pulmonary vein cryo-isolation in 13), right side maze operation in 18 patients, cavo-tricuspid isthmus cryoablation for benign atrial flutter in 4 patients, right ventricular endocardial cryoablation in 2 patients and extranodal cryoablation for atrioventricular node re-entry tachycardia in 1 patient. The median follow-up was 23.8 months ($1{\sim}95.2$ months). There was no early mortality, and one late non-cardiac related death. The overall rates of restored sinus rhythm before discharge and $3{\sim}6$ months after surgery were 79% and 81%, respectively (bi-atrial maze group: 72% and 83%, right-side maze group: 77%, 77%). Conclusion: Arrhythmias associated with congenital heart disease can be safely treated surgically with an excellent intermediate-term outcome.
Background: Pneumonectomy for inflammatory lung disease has been of major concern because of its associated morbidity and mortality, particularly with respect to pleuropneumonectomy. The purpose of this study is to evaluate the surgical outcomes, and identify the risk factors contributing to postoperative complications in patients undergoing pleuropneumonectomy. Material and Method: Ninety-eight patients underwent pneumonectomy for benign inflammatory lung disease were retrospectively analyzed. Pleuropneumonectomy (Group A) was done in 48 patients and standard pneumonectomy (Group B) was done in 50 patients. Clinical characteristics, postoperative complications were examined and compared between 2 groups. In pleuropneumonectomy group, postoperative risk factors affecting morbidity were evaluated. Result: There was one in-hospital death. Twenty-three major postoperative complications occurred in 21 patients (21.4%). The common complications were empyema and bronchopieural fistula (BPF) in 8 (8.4%), re-exploration due to bleeding in 8. At least one postoperative complication occurred in 14 of 48 patients from Group A (29.2%) and in 7 of 50 patients from Group B (14%). In Group A, empyema and BPF encountered in 6 and re-exploration for bleeding in 6 were the most common complication. In univariate analysis, right pneumonectomy, completion pneumonectomy, large amount of blood loss (>1,000 mL), and intrapleural spillage were risk factors contributing to postoperative complications in Group A. In multivariate analysis, intrapleural contamination during operation was a risk factor of postoperative complication. Conclusion: The morbidity and mortality rates of pneumonectomy for chronic inflammatory lung disease are acceptably. However, we confirm that pleuropneumonectomy is a real technical challenge and a high-risk procedure and technically demanding. Meticulous surgical techniques are very important in preventing serious and potentially lethal complications.
Purpose : Hysterectomy without lymph node dissection was considered an inadequate treatment method for invasive uterine cervix cancer. Usually the procedure was performed inadvertently on patients who were thought to have benign or premalignant conditions preoperatively. We analysed radiotherapy results of such patients to evaluate survival rates, failure patterns and prognostic factors according to various conditions. Materials and Methods : Sixty one patients undergoing hysterectomy in the presence of invasive cervical carcinoma were reviewed retrospectively. Preoperative diagnosis were carcinoma in situ (38 cases), severe dysplasia (2), myoma (6), uterine bleeding (4), uterine prolapse (2). and early invasive cervix cancer (10) (One patient had myoma and carcinoma in situ coincidently). Patients received postoperative megavoltage radiotherapy from August 1985 to December 1993, and minimum follow-up period was 24 months. Eight patients received ICR only, 6 patients ICR and external radiation, and 47 patients received external radiation therapy only. Results : Overall 5-year survival rate and relapse-free survival rate werer $83.8\%$, $86.9\%$ respectively. For patients with retrospective stage IA, IB, IIB (gross residual after surgery), and vaginal cuff recurrence were $90.9\%$, $88.8\%$, $38.4\%$, and $100\%$ respectively There were 8 cases of treatment failure, most of them (5/8) were in patients with gross residual disease, other patients were full thickness involvement of cervix wall (2/8) except one. Patients with early vaginal cuff recurrence and microinvasive cervical cancer (stage IA) had no treatment related failure Prognostic factors affecting survival by univariate analysis were status of residual disease, tumor histology and retrospective stage. Conclusion : Adjuvant radiotherapy appeared to be effective treatment method for patients with presumed stage IA, IB and early local recurrent disease after inadvertent hysterectomy Survivals for patients with gross disease remained after inappropriate hysterectomy was poor, So, early cancer detection and Proper management with precise pretreatment s1aging is necessary to avoid inadherent hysterectomy especially in the cases of gross residual disease.

Trichomonas vaginalis, a causative agent of trichomoniasis, may trigger symptomatic or asymptomatic non-gonococcal urethritis and chronic prostatitis in men. Despite the availability of highly sensitive diagnostic tests, such as nucleic acid amplification tests, including PCR, few prospective studies present data on male T. vaginalis infection in South Korea. In the present study, the prevalence of T. vaginalis and associated clinical conditions were evaluated in 201 male patients from a primary care urology clinic in South Korea. The prevalence of T. vaginalis infection in our cohort was 4% (8/201) by PCR. T. vaginalis infection was common in men older than 40 years (median age, 52 years). Among the 8 Trichomonas-positive patients, 87.5% (7/8) had prostatic diseases, such as prostatitis and benign prostatic hyperplasia, and 25.0% (2/8) and 12.5% (1/8) were coinfected with Chlamydia trachomatis and Mycoplasma genitalium, respectively. Our results suggest that T. vaginalis infection is not rare in men attending primary care urology clinics in South Korea, especially in those older than 40 years, in whom it may explain the presence of prostatic disease. The possibility of T. vaginalis infection should be routinely considered in older male patients with prostatic diseases in South Korea.
Desmoplastic fibroma(DF) is a rare neoplasm of the bone, and is histologically benign but locally aggressive disease. A total of nine cases of DF involving skull have been reported in the literature, and among these eight are females. In this report, the clinical findings and histopathology of a case with DF of the skull in a male patient is presented with a review of the literature with an emphasis on treatment modalities. A 21-year-old man presented with headache. CT scan revealed a solitary and lytic skull lesion without brain invasion. DF was confirmed by histological evaluation. On immunohistochemical staining of the tumor was negative for estrogen or progesterone receptors. After total resection of tumor with wide surgical margin, there was no recurrence during the 35 months of follow-up period. Although longer follow up period maybe needed, treatment of this type of tumor with complete resection of tumor tissue along with a wide margin may provide long disease-free state compare to the high recurrence rates in DF of other sites.
Background: There are limited data in the literature related to concomitant genital or extra-genital organ pathologies in patients with borderline ovarian tumors (BOTs). The aim of this study was to evaluate our experience with 183 patients to draw attention to the accompanying organ pathologies with BOTs. Materials and Methods: One hundred eighty-three patients with BOTs, diagnosed and/or treated in our center between January of 2000 and March of 2013 were evaluated retrospectively. Data related to age, tumor histology, lesion side, disease stage, accompanying incidental ipsilateral and/or contralateral ovarian pathologies, treatment approaches, and follow-up periods were investigated. Incidental gynecologic and non-gynecologic concomitant organ pathologies were also recorded. Results: The mean age at diagnosis was 40.6 years (range: 17-78). Ninety-five patients (51%) were ${\leq}40$ years. A hundred and forty-seven patients (80%) were at stage IA of the disease. The most common type of BOT was serous in histology. Non-invasive tumor implants were diagnosed in 4% and uterine involvement was found 2% among patients who underwent hysterectomies. There were 12 patients with positive peritoneal washings. Only 17 and 84 patients respectively had concomitant ipsilateral and concomitant contralateral incidental ovarian pathologies. The most common type of uterine, appendicular and omental pathologies were chronic cervicitis, lymphoid hyperplasia and chronic inflammatory reaction. Conclusions: According to our findings most of accompanying pathologies for BOT are benign in nature. Nevertheless, there were additional malignant diseases necessitating further therapy. We emphasize the importance of the evaluation of all abdominal organs during surgery.
