We reviewed the clinical course of 127 patients who underwent treatment for atherosclerotic disease between June 1993 and January 2001. There were 108 men and 19 women. The ages ranged from 49 to 88 years with a median age of 71.2 at the time of the first operation. Major risk factors included ischemic heart disease (21%) and diabetes mellitus (20%). Ninety-five percent of the patients were followed successfully and the follow-up period ranged from 0 to 90 months with a mean of 33 months. Two patients died perioperatively due to myocardial infarction. There were 29 late deaths. The overall actuarial survival rate was 69.7% at 5 years. The 5-year actuarial survival rate and the mean survival time for men and women were 71.6%, 66.1 months and 62.3%, 58.9 months. The 5-year late survival rate and the mean survival time for patients with and without ischemic heart disease were 57.0%, 57.4 months and 74.2%, 68.5 months. The differences were not statistically significant. The 5-year late survival rate and the mean survival time for patients with and without diabetes mellitus were 65.5%, 59.1 months and 70.9%, 67.4 months. The differences were not statistically significant. Amputation was performed in 7 patients, the actuarial survival rate at 1 year and the mean survival time were 42.9%, 7.1 months for patients with amputation, and 93.0%, 69.5 months without amputation (p<0.01).

Pulmonary rehabilitation is a common therapy for improving both exercise tolerance and quality of life (QoL) in patients with chronic obstructive pulmonary disease (COPD) . Although exercise is an important rehabilitation strategy, walking, treadmill use, bicycling and respiratory muscle training can be monotonous. A comprehensive exercise program that includes recreational activities may be a more effective means to decrease the occurrence of dyspnea during daily activities and improve QoL in patients with COPD. The purpose of this study was to investigate the effects of our exercise therapy, including recreational activities and respiratory muscle training, on dyspnea and health related QoL (HRQL) in COPD patients. Thirty-eight male patients with COPD were randomly assigned to a control (C) (70.1±6.4yr) (n=12) . pulmonary rehabilitation (PR) (70.3±8.3yr) (n= 16), or exercise (EX) (68.7±4.6yr) (n=10) group. The following evaluations were performed at baseline and at 8 weeks: (1) cycle ergometer test ; (2) 6-min walking distance : (3) physical fitness (4) pulmonary function ; (5) dyspnea : and (6) HRQoL (SF-36) . The C group showed no significant changes in physical fitness, pulmonary function, dyspnea, and HRQoL scores throughout the observation period. There was a significant (P<0.05) improvement in 6-min walking distance. physical fit-ness, maximum rnspiratory pressure (MIP), and HRQoL for the PR group. The EX group demons-trated a significant (P<0.05) improvement in physical fitness, maximum expiratory pressure (MEP), dyspnea, and HRQoL. Moreover, the degree of improvement in each variable was greater for EX than for PR. There were significant (P<0.05) correlations between MIP and FEV_1.0 (r=0.65), and between MEP and FEV_1.0 (r=0.43) . Based on these results, it appears that our comprehensive exercise program, including recreational activities and respiratory muscle training, improves physical fitness, pulmonary function, dyspnea, and quality of life in COPD patients.

Re-do open cardiac surgery may sometimes require complete ablation around the pericardium for the 2 major reasons of attaining better myocardial protection and obtaining effective DC cardioversion. However, this ablation may increase postoperative hemorrhage which may require blood transfusion. Hypothermia is based on the concept of myocardial protection during open heart surgery by suppressing myocardial metabolism, but recently the approach has been changed to maintaining myocardial metabolism with aerobic or anaerobic energy production. We have already reported that histidine-buffered cardioplegia which promote anaerobic glycolysis, provided an excellent functional recovery of myocardium post-ischemia with lower inotropic requirements in a range from 10°C to 37°C of myocardial temperature. Based on our theoretical background and clinical data, we tested the efficacy of this type of cardioplegia in patients receiving multiple surgical procedures with minimum ablation after sternotomy. First case, who had undergone a Bentall procedure for annulo-aortic ectasia 14 years previously had a thrombotic valve and mitral regurgitation. Aortic valve plasty and mitral valve replacement (MVR) was performed. The second case who had undergone MVR 15 years previously had malfunction of the prosthetic valve and underwent re-MVR. The third and fourth cases had ventricular septal defect (VSD) which were closed using Teflon patches. The third case had patch closure during second operation for residual shunt. The fourth case received tricuspid valve replacement (TVR) for tricuspid regurgitation due to a pacemaker lead implanted into the right ventricle through the left subclavian vein. The fifth case received coronary artery bypass surgery in a second operation for restenosis of the graft and progressing atherosclerosis. All hearts started beating spontaneously without DC cardioversion after the aortic unclamp. Ventricular fibrillation occurred in the first case while the patient was weaned from cardiopulmonary bypass and treatment was performed by aortic cross clamp, infusion of the cardioplegia followed by aortic unclamp to start own beat again. Two of 3 patients who were able to donate their own blood preoperatively did not require homologous blood transfusion. Due to advantages such as excellent myocardial protection under hypothermic or normothermic condition, ease of use and relatively lower potassium concentration, histidine-buffered cardioplegia can be an excellent candidate for myocardial protection in re-do cases with less ablation technique.

A 62-year-old woman with the tetralogy of Fallot (TOF) diagnosed at 24 years of age, was admitted with fever and dyspnea. She also had cyanosis and heart failure and was categorized as New York Heart Association (NYHA) functional class IV. Echocardiography showed TOF with a-grade III tricuspid valve regurgitation. Cardiac catheterization revealed major aorto-pulmonary collateral arteries (MAPCAs) for the left upper pulmonary circulation. After coil embolization of MAPCAs to reduce abnormal intracardiac return as well as postoperative left ventricular volume overload, the patient underwent total surgical correction (i.e., right ventricular outflow tract reconstruction using Medtronic FreeStyle Valve and transannular patch, ventricular septal defect closure, and tricuspid annuloplasty). Postoperatively, the patient had a satisfactory course during the 10-year follow-up period with a grade-I NYHA classification. In conclusion, intracardiac repair of TOF in case over 60 years of age can be performed safely by preoperative MAPCAs embolization and subsequent TOF repair with a strategy to abolish pulmonary and tricuspid valve regurgitation.

BACKGROUND AND PURPOSE: Factors associated with early arrival may vary according to the characteristics of the hospital. We investigated the factors associated with early hospital arrival in two different stroke centers located in Korea and Japan. METHODS: Consecutive patients with ischemic stroke arrived hospital within 48 hours of onset between January 2011 and December 2012 were identified and the clinical and time variables were retrieved from the prospective stroke registries of Severance Hospital of Yonsei University Health System (YUHS; Seoul, Korea) and National Cerebral and Cardiovascular Center (NCVC; Osaka, Japan). Subjects were dichotomized into early (time from onset to arrival < or =4.5 hours) and late (>4.5 hours) arrival groups. Univariate and multivariate analyses were performed to evaluate factors associated with early hospital arrival. RESULTS: A total of 1,966 subjects (992 from YUHS; 974 from NCVC) were included in this study. The median time from onset to arrival was 6.1 hours [interquartile range, 1.7-17.8 hours]. In multivariate analysis, the factors associated with early arrival were atrial fibrillation (Odds ratio [OR], 1.505; 95% confidence interval [CI], [1.168-1.939]), higher initial National Institute of Health Stroke Scale scores (OR, 1.037; 95% CI [1.023-1.051]), onset during daytime (OR, 2.799; 95% CI [2.173-3.605]), and transport by an emergency medical service (OR, 2.127; 95% CI [1.700-2.661]). These factors were consistently associated with early arrival in both hospitals. CONCLUSIONS: Despite differences between the hospitals, there were common factors related to early arrival. Efforts to identify and modify these factors may promote early hospital arrival and improve stroke outcome.

BACKGROUND/AIMS: This study aimed to examine the diagnostic ability of endoscopic ultrasonography (EUS) for major vascular invasion in pancreatic cancer and to evaluate the relationship between EUS findings and pathological distance. METHODS: In total, 57 consecutive patients who underwent EUS for pancreatic cancer before surgery were retrospectively reviewed. EUS image findings were divided into four types according to the relationship between the tumor and major vessel (types 1 and 2: invasion, types 3 and 4: non-invasion). We also compared the EUS findings and pathologically measured distances between the tumors and evaluated vessels. RESULTS: The sensitivity, specificity, and accuracy of EUS diagnosis for vascular invasion were 89%, 92%, and 91%, respectively, in the veins and 83%, 94%, and 93%, respectively, in the arteries. The pathologically evaluated distances of cases with type 2 EUS findings were significantly shorter than those of cases with type 3 EUS findings in both the major veins (median [interquartile range], 96 [0–742] µm vs. 2,833 [1,076–5,694] µm, p=0.012) and arteries (623 [0–854] µm vs. 3,097 [1,396–6,000] µm, p=0.0061). All cases with a distance of ≥1,000 µm between the tumors and main vessels were correctly diagnosed. CONCLUSIONS: Tumors at a distance ≥1,000 µm from the main vessels were correctly diagnosed by EUS.

Purpose: This study was performed to evaluate the prognostic value of preoperative C-reactive protein to albumin ratio (CAR) in older patients with colorectal cancer (CRC) undergoing curative resection. Methods: We retrospectively analyzed 244 older patients (aged 75 years or higher) with pathological stage II or III CRC who underwent curative surgery between 2008 and 2016. The optimal value of CAR was calculated and its correlation with the clinicopathological factors and prognosis was examined. Results: The optimal cutoff value of the CAR was 0.085. High preoperative CAR was significantly associated with high carcinoembryonic antigen levels (P=0.001), larger tumor size (P<0.001), and pT factor (P=0.001). On multivariate analysis, high CAR was independent prognostic factor for relapse-free survival (P=0.042) and overall survival (P=0.001). Conclusion Preoperative elevated CAR could be considered as an adverse predictor of both relapse-free survival and overall survival in older patients with CRC undergoing curative surgery.

Purpose: General surgeons at regional hospitals should have the primary trauma care skills necessary to treat critically ill trauma patients to withstand transfer. This study was conducted to identify a consensus on primary trauma care skills for general surgeons. Methods: An initial list of acute care surgical skills was compiled, and revised by six trauma experts (acute care surgeons); 33 skills were nominated for inclusion in the Delphi consensus survey. Participants (councilors of the Japanese Society for Acute Care Surgery) were presented with the list of 33 trauma care skills and were asked (using web-based software) to rate how strongly they agreed or disagreed (using a 5-point Likert scale) with the necessity of each skill for a general surgeon. The reliability of consensus was predefined as Cronbach’s α ≥ 0.8, and trauma care skills were considered as primarily required when rated 4 (agree) or 5 (strongly agree) by ≥ 80% participants. Results: There were 117 trauma care specialists contacted to participate in the Delphi consensus survey panel. In the 1st round, 85 specialists participated (response rate: 72.6%). In the 2nd round, 66 specialists participated (response rate: 77.6%). Consensus was achieved after two rounds, reliability using Cronbach’s α was 0.94, and 34 items were identified as primary trauma care skills needed by general surgeons. Conclusion A consensus-based list of trauma care skills required by general surgeons was developed. This list can facilitate the development of a new trauma training course which has been optimized for general surgeons.

BACKGROUND/AIMS: Venous thromboembolism (VTE) is a major extraintestinal manifestation in inflammatory bowel disease (IBD), regarded as an independent risk factor for VTE according to reports from Western countries. However, the incidence and risk factors of VTE in Asian IBD patients are not fully understood. We aimed to reveal the incidence and risk factors of VTE in Japanese IBD inpatients. METHODS: The incidence of VTE in inpatients with IBD (n=340), gastrointestinal cancers (n=557), and other gastrointestinal diseases (n=569) treated at our hospital from 2009 to 2013 was retrospectively investigated. The characteristics and laboratory data of IBD inpatients with and without VTE were compared in univariate and multivariate analyses. Clinical courses of VTE in IBD were surveyed. RESULTS: VTE was detected in 7.1% of IBD inpatients, significantly higher than in gastrointestinal cancer inpatients (2.5%) and inpatients with other gastrointestinal diseases (0.88%). The incidence of VTE in ulcerative colitis (UC) patients (16.7%) was much higher than that in those with Crohn's disease (3.6%). In the univariate analysis, the risk factors were an older age, central venous catheter, prednisolone, surgery, low serum albumin, high serum C-reactive protein and D-dimer. According to a multivariate analysis, >50 years of age and surgery were the only risk factors. The in-hospital mortality rate of IBD inpatients with VTE was 4.2%. CONCLUSIONS: The incidence of VTE with IBD, especially UC, was found to be high compared with other digestive disease, which was almost equivalent to that of Western countries. The efficacy of prophylaxis needs to be investigated in Asian IBD patients.
