Background: Recently, percutaneous cardiopulmonary support (PCPS) has been widely used to rescue patients in cardiogenic shock or cardiac arrest. However, patients with cardiopulmonary bypass (CPB) weaning failure during open heart surgery still have very poor outcomes after PCPS. We investigated clinical results and prognostic factors for patients who underwent PCPS during open heart surgery. Material and Method: From January 2005 to December 2008, 10 patients with CPB weaning failure during open heart surgery underwent PCPS using the CAPIOX emergency bypass system ($EBS^{(R)}$, Terumo Inc, Tokyo, Japan). We retrospectively reviewed the medical records of those 10 patients. Result: The average age of the patients was $60.2{\pm}16.5$ years (range, $19{\sim}77$ years). The mean supporting time was $48.7{\pm}64.7$ hours (range, $4{\sim}210$ hours). Of the 10 patients, 6(60%) were successfully weaned from the PCPS While 5 (50%) were able to be discharged from the hospital. Complications were noted in 5 patients (50%). In univariate analysis, long aortic cross clamp time during surgery, mediastinal bleeding during PCPS and high level of Troponin-I before PCPS were significant risk factors. All of the discharged patients are still surviving $34{\pm}8.6$ months (range, $23{\sim}48$ months) post-operatively. Conclusion: The use of PCPS for CPB weaning failure during open heart surgery can improve the prognosis. More experience and additional clinical studies are necessary to improve survival and decrease complications.

Objective:Korea has 3,170 islands with about 188,000 inhabitants. These inhabitants' needs for health services might go unmet because of geographic isolation, slimmer availability of health services, and higher proportion of the elderly compared with the mainland population. Unmet health service needs might result in serious health problems for these island residents. Therefore, the purpose of this study was to investigate their unmet health service needs and related factors from population of Nowha island. Methods: The survey was conducted from July 30 to August 1 by trained interviewers. Target population were residents in Nohwa island and the sampling method was incomplete quota sampling. General characteristics, socioeconomic status, utilization of health service, and unmet medical service needs were investigated. First univariate and then multivariate logistic analyses were done for the statistical analysis. Results: 324 residents were surveyed and the proportion of unmet health services needs was 26.5%. People living alone and of female sex had increased health services needs based on univariable analysis. From the multivariate analysis, those living alone increased the health services needs. Self-determined low socioeconomic status and medical aid increased the proportion of unmet medical needs, but these were not statistically significant. Conclusion:In Nowha island, those who are elder, and of lower socioeconomic status had much higher unmet medical needs. The results suggest the need for more social support by qualified health services to solve this unmet medical needs problem.
Background: The purpose of this study was to determine the benefit of tertiary cytoreductive surgery (TC) for secondary recurrent epithelial ovarian cancer (EOC), focusing on whether optimal cytoreduction has an impact on disease-free survival, and whether certain patient characteristics could identify ideal candidates for TC. Materials and Methods: Retrospective analysis of secondary recurrent EOC patients undergoing TC at three Turkish tertiary institutions from May 1997 to July 2014 was performed. All patients had previously received primary cytoreduction followed by intravenous platinum-based chemotherapy and secondary cytoreduction for first recurrence. Clinical and pathological data were obtained from the patients' medical records. Survival analysis was caried out using the Kaplan Meier method. Actuarial curves were compared by the two tailed Logrank test with a statistical significance level of 0.05. Results: Median age of the patients was 49.6 years (range, 30-67) and thirty-eight (72%) had stage III-IV disease at initial diagnosis. Twenty six (49%) had optimal and 27 (51%) suboptimal cytoreduction during tertiary debulking surgery. Optimal initial cytoreduction, time to first recurrence, optimal secondary cytoreduction, time interval between secondary cytoreduction and secondary recurrence, size of recurrence, disease status at last follow-up were found to be significant risk factors to predict optimal TC. Optimal cytoreduction in initial and tertiary surgery and serum CA-125 level prior to TC were independent prognostic factors on univariate analysis. Conclusions: Our results and a literature review clearly showed that maximal surgical effort should be made in TC, since patients undergoing optimal TC have a better survival. Thus, patients with secondary recurrent EOC in whom optimal cytoreduction can be achieved should be actively selected.

Purpose : To evaluate the prevalence and pattern of perfusion defect (PD) on first-pass stress perfusion MR imaging in relation with the degree of left ventricular hypertrophy (LVH) and late gadolinium-enhancement (LGE) in patients with apical hypertrophic cardiomyopathy (APH). Materials and Methods: Cardiac MR imaging with first-pass stress perfusion, cine, and LGE sequence was performed in 26 patients with APH from January 2008 to December 2012. We analyzed a total of 416 segments for LV wall thickness on end-diastolic phase of cine images, and evaluated the number of hypertrophied segment and number of consecutive hypertrophied segment (NCH). We assessed the presence or absence of PD and LGE from all patients. If there was PD, we subdivided the pattern into sporadic (sporadic-PD) or ring (ring-PD). Using univariate logistic method, we obtained the independent predictor for presence of overall PD and ring-PD. Results: PD on stress perfusion MRI was observed in 20 patients (76.9%), 12 of them (60%) showed ring-PD. Maximal LV wall thickness and number of hypertrophied segment were independent predictors for overall PD (all, p < 0.05). NCH with more than 3 segments was an additional independent factor for ring-PD. However, LGE was not statistically related with PD in patients with APH. Conclusion: About three quarters of the patients with APH showed PD, most of them represented as ring-PD. LVH degree or distribution was related with pattern of PD, however, LGE was not related with PD. Therefore, the clinical significance of PD in the patients with APH seems to be different from those with non-APH, and further comparison study between the two groups should be carried out.
Background: Interrupted aortic arch is a rare congenital heart anomaly which still shows high surgical mortality. In this study, we investigated the causes of and the risk factors for mortality to improve the surgical outcomes for this difficult disease entity. Material and Method: From 1984 to 2004, 42 patients diagnosed as IAA were reviewed retrospectively. Age, body weight at operation, preoperative diagnosis, preoperative PGE1 requirement, type of interrupted aortic arch, degree of left ventricular outflow stenosis, CPB time, and ACC time were the possible risk factors for mortality. Result: There were .14 hospital deaths. Preoperative use of PGE1, need for circulartory assist and aortic cross clamp time proved to be positive risk factors for mortality on univariate analysis. Preoperative left ventricular outflow stenosis was considered a risk factor for mortality but it did not show statistical significance (p-value=0.61). Causes of death included hypoxia due to pulmonary banding, left ventricular outtract stenosis, infection, mitral valve regurgitation, long cardiopulmonary bypass time and failure of coronary transfer failure in TGA patients. Conclusion: In this study, we demonstrated that surgical mortality is still high due to the risk factors including preoperative status and long operative time. However preoperative subaortic dimension was not related statistically to operative death statistically. Adequate preoperative management and short operation time are mandatory for better survival outcome.

Purpose : To evaluate our experience in the breast-conserving treatment for early breast cancer with special regard to recurrence Pattern and related risk factors. Materials and Method :Two hundred and sixteen patients with AJC stage 1and 11 breast cancer who received breast conserving treatment between January 1991 and December 1994 were evaluated A9e distribution ranged from 23-80 year old with a median a9e of 44. One hundred and seventeen Patients had 71 lesions and 99 Patients had 72 lesions. Axillary lymph nodes were involved in 73 patients. All patients received a breast conserving surgery (wide excision to quadrantectomy) and axillary node dissection followed by radiotherapy. Ninety six patients received chemotherapy before or after radiotherapy. Results : During the follow-up period (3-60 months, median 30 months), local recurrences were noted in six Patients (true: 3, elsewhere; 1, skin: 2). Sixteen patients developed distant metastases as the first sign of recurrence at 8-38 months (median 20 months) after surgery. Among them, three patients simultaneously developed local recurrence with distant metastases. Contralateral breast cancer developed in one Patient and non-mammary cancers developed in three patients. The actuarial 5 year survival rate was $88.4\%\;(stage\;I\;96.7\%,\;stage\;IIa\;95.2\%,\;stage\;IIb\;69.9\%)$. Age, I stage, number of involved axillary lymph nodes. and AJC stage were risk factors for distant metastases in univariate analysis. In the multivariate analysis, the number of involved axillary lymph nodes was the most significant risk factor for metastases. Conclusion : Local recurrence was not common in the early years after radiotherapy. Distant metastases occurred at a steady rate during the first three years and was more common in the Patients with larger tumors, higher number of involved axillary nodes, and younger age.

Background: Failed percutaneous transluminal coronary angioplasty (PTCA) is occasionally required for emergency coronary artery bypass grafting (CABG). The aim of this study was to assess the outcome of patients receiving emergency CABG after failed PTCA. Material and Method: Between May 1988 and May 2005, 5712 patients underwent PTCA, where 84 (1.4%) failed. 27 patients underwent emergency CABG after failed PTCA. The mean age was $63.7{\pm}8.9\;(46{\sim}80)$ years, with 14 male patients (51.9%). Result: All patients underwent emergent surgical revascularization within 6 hours. 22 patients underwent conventional CABG and 5 underwent off-pump CABG. The causes of PTCA failure were coronary obstruction due to new thrombi formation during the procedure (n=4), coronary dissection (n=17), coronary artery rupture (n=3) and 3 due to other causes. The rate of in-hospital operative mortality after emergent operation was 18.5% (5/27). A univariate analysis revealed that patients who died more often had left anterior descending artery disease, a preprocedural shock status, postoperative use of multiple isotropics and postoperative use of intra-aortic balloon pump. The mean follow up duration was $53.6{\pm}63.4$ months. Conclusion: Although PTCA is known to be life saving, there is still a high risk for morbidity and mortality following emergency CABG after failed PTCA, despite the advancement in PTCA techniques. This result will help identify and more effectively treat patients selected for PTCA when emergency CABG is required.
Background: Surgical resection is accepted widely as the standard therapy for complete resectable pulmonary metastases. The number of cases of pulmonary metastasectomy and its survival rate is increasing due to the development of the therapeutic modalities. We attempted to analyze the survival rate and prognosis factors of pulmonary metastasectomy during the last 10 years. Material and Method: We retrospectively analyzed the data of 89 patients who underwent 96 procedures of pulmonary metastasectomy between January 1996 and December 2005. The factors that may influence the long term prognosis such as completeness of resection, the type of primary cancer, the disease-free interval, the number and size of metastasis and the laterality were investigated. Result: There was no operative mortality. The mean disease free interval (DFI) was $29.6{\pm}27.9$ months and there were 3 cases of synchronous metastasis (3.4%). The overall 3, 5 and 10 year survival rate was 52.5%, 32.1% and 20.7%, respectively. The median survival time was 38 months. The 5-year survival rate according to the IRLM appraisal was 63.5%, 33.3%, 22.1% and 0% for stage I, II, III and IV, respectively Univariate analysis showed a better prognosis for patients with a disease free interval of 36 months or more, unilateral metastasis and 4 or less metastases. Conclusion: The survival rate for completely resectable pulmonary metastasectomy was favorable. The disease free interval, laterality and the number of metastasis were the prognosis factors.
Purpose :The aim of this study is to analysis of suwival and recurrence rates of the uterine cervical carcinoma patients whom received the radiation therapy respectively. The prognostic factors, such as Papanicolaou (Pap) smear, carcinoembriogenic antigen (CEA) and squamous cell carcinoma (SCC) antigen has been studied. Methods and Materials : From January 1981 to December 1998, eight-hundred twenty-seven uterine carvical cancer patients were treat with radiation therapy. All of the patients were divided into two groups : the radiation therapy only (S2l patients) group and the postoperative radiation therapy (326 patients) group. The age, treatment modality, clinical stage, histopathology, recurrence, follow-up Pap smears, CEA and SCC antigen were used as parameters for the evaluation. The prognostic factors such as survival and recurrence rates were peformed with the Kaplan-Meier method and the Cox hazard model, respectively. Median rollow-up was 38.6 months. Results :On the radiation therapy only group, 314 patients (60$\%$) achieved complete response (CR), 47 patients (9$\%$) showed local recurrence (LR), 78 patients (15$\%$) developed distant metastasis (DM). On the Postoperative radiation therapy group, showed 276 Patients (85$\%$) CR, 8 Patients (2$\%$) LR, 37 Patients (11$\%$) DM. The 5-year survival and recurrence rates was evaluated for all parameters. The statistically significant factors for the survival rate in univariate analysis were clinical stage (p=0.0001), treatment modality (p=0.0010), recurrence (p=0.0001), Pap smear (p=0.0329), CEA (p=0.0001) and SCC antigen (p=0.0001). Conclusion: This study indicated that after treatment, the follow-up studies of Pap smear, CEA and SCC antigen were significant parameter and prediction factors for the survival and recurrence of the uterine cervical carcinoma.

Purpose : This study was performed to analyze the factors affecting local control in malignant tumors of the parotid gland treated with surgery and postoperative radiation. Materials and methods : Twenty-six patients were treated for malignant tumors of the parotid gland from 1986 to 1995 at Department of Therapeutic Radiology, Chonnam University Hospital. Age of the patients ranged from 14 to 72 years (median : 55 years). Histologically 10 patients of mucoepidermoid carcinoma, 7 of squamous cell carcinoma, 4 of acinic cell carcinoma, 4 of adenoid cystic carcinoma and 1 of adenocarcinoma were treated. Total parotidectomy was performd in 15 of 26 patients, superficial in 7, subtotal in 4. Facial nerve was sacrificed in 5 patients. Postoperatively 4 patients had residual disease, 4 had positive resection margin. Radiation was delivered through an ipsilateral wedged pair of photon in 11 patients. High energy electron beam was mixed with photon in 15 patients. Electron beam dose ranged from 900 cGy to 3800 cGy (median 1700 cGy). Total radiation dose ranged from 5000 cGy to 7560 cGy (median : 6020 cGy). Minimum follow-up period was 2 years. Local control and survival rate were calculated using Kaplan-Meier method. Generalized Wilcoxon test and Cox proportional hazard model were used to test factors affecting local control. Results : Five (19$\%$) of 26 patients had local recurrence. Five year local control rate was 77$\%$. Overall five year survival rate was 70$\%$. Sex, age, tumor size, surgical involvement of cervical lymph node, involvement of resection margin, surgical invasion of nerve, and total dose were analyzed as suggested factors affecting local control rate. Among them patients with tumor size less than 4 cm (p=0.002) and negative resection margin (p=0.011) were associated with better local control rates in univariate analysis. Multivariate analysis showed only tumor size factor is associated with local control rate (p=0.022). Conclusion : This study suggested that tumor size is important in local control of malignant tumors of parotid gland.
