The combined superior transsseptal approach (CSTA) has been used for 12 mitral or left atrial myxoma operations. This approach provided excellent exposure of the mitral valve or myxoma. This approach was compared with the transseptal and left atrial approaches in 1 and 3 cases, respectively. There were no differences in operative time, cardiopulmonary bypass time, anoxic time, bleeding volume, blood transfusion volume and postoperative arrhythmic complications. We use CSTA for cases with tricuspid valve disease, small left atrium, reoperation and left atrial myxomas.

Background: Laparoscopy-assisted gastrectomy requires a lot of disposable products. So we compared the cost between laparoscopy-assisted gastrectomy and open surgery.Patients and methods: For comparison we used five cases each of open distal gastrectomy (ODG), laparoscopy-assisted distal gastrectomy (LADG), open total gastrectomy (OTG) and laparoscopy assisted total gastrectomy (LATG). In this study, we defined the profit of gastrectomy as below and we used the list price for all products. Profit of gastrectomy=Fee for gastrectomy-(Costs of all single use products-Demandable fee for single-use products)Results: Mean profits of ODG and LADG were 278,756.2 yen and 190,292.8 yen. The difference was 88,463.4 yen. Mean profits of OTG and LATG were 395,922.6 yen and 330,653.6 yen. The difference was 65,269 yen. Mean hospital charges, mean length of hospital stay, mean hospital charges per day of ODG, LADG, OTG and LATG were 1,390,464 yen, 21.4 days, 65,140.0 yen and 1,484,254.0 yen, 18.8 days, 80,805.4 yen and 1,956,664.0 yen, 24.4 days, 82,397.1 yen and 1,686,936.0 yen, 18.4 days, 91,894.8 yen, respectively.Conclusion: The turnover of laparoscopic gastrectomy was higher than open gastrectomy, but, the profit was lower because of high costs of disposable products. Hospital charges were not higher but the charge per day was higher because of a shorter hospital stay.

Recently, in addition to standard surgical operations, reduction therapy (endoscopic mucosal resection and endoscopic gastrectomy) is indicated for early gastric cancer. However, the indication should be limited to the casesof early gastric cancer without lymph node metastases.
During the past 25 years, we have surgically treated 2, 246 cases of early gastric cancer. The percentage of lymph node metastasis in 1, 242 mucosal cancer cases was 1.8% and that in 1, 004 submucosal cancer cases was 16.9%. In the mucosal cancer cases, lymph node metastasis did not occur in the depressedtumors with a diameter of less than 10mm and the elevated tumors with a diameted of less than 20mm. In the submucosal cancer cases, lymph node metastasis did not occur in the elevated tumors less than 10mm in diameter. So, the cases of gastric cancerof these types require the reduction therapy.
However, in the mucosal cancers that have been diagnosed during the last 5 years, the percentage of preoperative correct diagnosis as for thedepth of invasion was 69.4%. In the submucosal cancers, the rate was 60.1%. Many of the cases diagnosed incorrectly had ulcers in the lesion. As for the infiltration type, INFβ and γ were noticeable in these cases. As for the histological type, most of the cases wereof the undifferentiated type.
Moreover, if should be noted, the percentage that the histological type of preoperative ensoscopic biopsy specimens agrees with that of postoperative ones is 50-60% except for tubl of mucosal cancers.

Objective: The benefits of combining cancer screenings with clinical surveys have become increasingly obvious as cancer morbidity and mortality have steadily increased. This paper discusses a study on the current status of and issues surrounding breast cancer screening in a clinical survey. The study also investigated the patients' awareness of the benefits of breast cancer screening. A secondary aim of the study was to promote mammographic screening.;Subjects and Methods: During the 72 months between April 1999 and March 2005, a total of 36,505 women underwent clinical surveys in our hospital. In October 2002, mammographic examination was included as an optional part of the routine physical examination. We evaluated the results of breast cancer screening with or without mammographic examination and used a questionnaire to investigate the patients' awareness of the benefits of breast cancer screening.;Results: Compared with the pre-2001 results, the detection rate of breast cancer significantly increased after 2003 when physical examination was combined with mammographic examination. Our study also found that both elderly patients and those residing in the suburbs of Sapporo City tended to choose physical examination alone rather than combining it with mammographic examination. An analysis of the questionnaires collected from these patients indicates they had a poor understanding of and lacked awareness of the benefits of mammographic examinations during breast cancer screenings.;Conclusions: The inclusion of mammographic screenings with clinical surveys was found to be significantly useful in the detection of breast cancer. Further continued education is needed for women, particularly the elderly and residents in the suburbs, so they understand the benefits of breast cancer screening by mammographic examination for the early detection of breast cancer and, consequently, decreased mortality of the disease.

BACKGROUND:
To let the early elderly live well, understanding how lifestyle and psychosocial factors related to a decline in competence in daily living is important.
METHODS:
We investigated the associations between lifestyle and psychosocial factors at age 64 years and a decline in the Tokyo Metropolitan Institute of Gerontology Index of Competence score of ≥ 2 points at age 70 years among the participants in comprehensive medical check-ups living in a city in Japan. Multivariable logistic regression analyses were performed separately for men and women.
RESULTS:
Of the 1113 eligible men and 1203 eligible women, 110 men and 80 women showed a deteriorated competence in daily living during the 6 years. In men, risk was increased with ≥ 2 nighttime awakenings (multivariable odds ratio [mOR] 2.14, 95% confidence interval [CI] 1.19-3.86) and living alone (mOR 4.68, 95% CI 1.22-18.0), whereas risk was significantly decreased with a medium or fast gait (mOR 0.37 and 0.21, 95% CI 0.21-0.67 and 0.08-0.58) and high academic achievement (mOR 0.32 and 0.43, 95% CI 0.19-0.53 and 0.25-0.72). In women, risk was decreased with high life satisfaction (mOR 0.39, 95% CI 0.16-0.91) and participation in community activities (mOR 0.50, 95% CI 0.29-0.86) but increased with depressive mood (mOR 1.86, 95% CI 1.09-3.18).
CONCLUSION
Living alone for men and low life satisfaction for women at age 64 years were markedly associated with the risk of a subsequent declining competence in daily living.

BACKGROUND:
Predicting adverse health events and implementing preventative measures are a necessary challenge. It is important for healthcare planners and policymakers to allocate the limited resource to high-risk persons. Prediction is also important for older individuals, their family members, and clinicians to prepare mentally and financially. The aim of this study is to develop a prediction model for within 11-year dependent status requiring long-term nursing care or death in older adults for each sex.
METHODS:
We carried out age-specified cohort study of community dwellers in Nisshin City, Japan. The older adults aged 64 years who underwent medical check-up between 1996 and 2000 were included in the study. The primary outcome was the incidence of the psychophysically dependent status or death or by the end of the year of age 75 years. Univariable logistic regression analyses were performed to assess the associations between candidate predictors and the outcome. Using the variables with p-values less than 0.1, multivariable logistic regression analyses were then performed with backward stepwise elimination to determine the final predictors for the model.
RESULTS:
Of the 1525 female participants at baseline, 105 had an incidence of the study outcome. The final prediction model consisted of 15 variables, and the c-statistics for predicting the outcome was 0.763 (95% confidence interval [CI] 0.714-0.813). Of the 1548 male participants at baseline, 211 had incidence of the study outcome. The final prediction model consisted of 16 variables, and the c-statistics for predicting the outcome was 0.735 (95% CI 0.699-0.771).
CONCLUSIONS
We developed a prediction model for older adults to forecast 11-year incidence of dependent status requiring nursing care or death in each sex. The predictability was fair, but we could not evaluate the external validity of this model. It could be of some help for healthcare planners, policy makers, clinicians, older individuals, and their family members to weigh the priority of support.
