Abstract
199 Background: As the population ages, elderly patients are being diagnosed with periampullary tumors, and hence, it has been suggested that surgeons should consider the indications for pancreaticoduodenectomy (PD) in elderly patients. The aim of this study is to reveal risks and benefits of PD, and is to identify prognostic inflammatory biomarkers for major complications after PD in patients aged 80 years or older. Methods: We retrospectively analyzed the cases of 161 consecutive patients who underwent PD between January 2000 and December 2015, and compared the patients aged ≥ 80 years (n = 22) with those aged < 80 years (n = 139). Postoperative results and preoperative conditions such as nutrition status using controlling nutritional status (CONUT) score, hemoglobin level and comorbidity were assessed. Correlations were evaluated between major postoperative complications (Clavien-Dindo grade III or higher) and 6 systemic inflammation–based prognostic score such as Glasgow prognostic score (GPS), modified-GPS, High sensitive-mGPS, neutrophil-lymphocyte ratio, platelet-lymphocyte ratio (PLR), and prognostic nutritional index in elderly patients. Results: There was no operative mortality. In elderly patients, preoperative hemoglobin level was lower and CONUT score was higher than in younger patients. The complication rates and the disease-specific survival did not differ significantly between the two groups. Ten patients (45%) experienced major complications in the elderly group. Among 6 systemic inflammation–based prognostic score, only PLR was revealed as predictor of major complications (p = 0.012) and optimal cutoff value was determined to be 145.3 (sensitivity = 33%, specificity = 100%, AUC = 0.842). Conclusions: PD could be performed safely in patients aged 80 years or older. The preoperative PLR was a simple and useful predictor of major complications after PD in elderly patients.

Abstract
Background: In 2016, gastric cancer is the second leading cause of cancer mortality worldwide. Globally, Japan and Korea are the only two countries implementing national screening program for gastric cancer. South Korea launched a biennial national -endoscopic screening program in 1999, which demonstrated a 47% reduction in gastric cancer mortality compared with no screening. In 2015, endoscopic screening was recommended by the Japanese Guideline for Gastric Cancer Screening. Currently, Japan's screening policy recommends endoscopic screening every 2 to 3 years for individuals aged 50 or above. Aim: This study aims to quantify the potential impacts of Japan's current national endoscopic screening policy and other alternative endoscopic screening options, and to identify a set of efficient endoscopic screening strategies for the current population of Japan. Methods: A microsimulation model of intestinal-type noncardia gastric adenocarcinoma was developed to simulate a virtual population with similar risk profile and life expectancy to the actual population of Japan. The model was calibrated and validated to the nationally-representative data from vital statistics and population-based cancer registries. The baseline scenario was modeled to project the current trend of gastric cancer. Variations among age of initiation (40, 45, 50, and 55), age of termination (75, 80, and 85), and screening interval (2, 5, 10, and 15 years) resulted in 39 unique endoscopic screening strategies for evaluation. In addition, the following three existing screening scenarios were included for analysis: the current screening program in Japan (screening every two or three years from age 50 years, with no termination) and Korea (biennial screening from age 40 years, with no termination). In total, 42 unique endoscopic screening strategies were simulated. Full adherence for all screening scenarios were assumed. Results: In comparison with baseline scenario, endoscopic screening strategies provided 43 to 203 life-years gained per 1000 individuals. The number of lifetime endoscopies per 1000 individuals ranged from 2281 to 28,635. The complications caused by screening were from 6 to 77 per 1000 individuals. The lifetime number of false-positive results ranged from 381 to 4941 per 1000 individuals. Scenarios simulating the current national endoscopic screening program in Japan and Korea fell below the efficient frontier. Under full adherence assumption, the most advantageous endoscopic screening strategy among evaluated scenarios is screening from age 40 to 80 years every 5 year. Conclusion: In this microsimulation modeling study with full adherence assumption, the findings suggest that the current national endoscopic screening program for gastric cancer in Japan might not be the most efficient screening option under benefit-to-harm consideration. The finding underpins the need for further investigation to bring up an efficient and cost-effective endoscopic screening program in Japan.

Abstract
Residual barium in intraperitoneal cavity causes persistent inflammatory reaction. Steroids are effective for persistent inflammation caused by residual barium. If infectious or other inflammation origins exist, steroids should be avoided.
Introduction Barium peritonitis is a serious and life-threatening disease requiring intensive care. Residual barium in the intraperitoneal cavity can cause persistent inflammation, postoperatively. Presentation of case An 80-year-old woman was admitted to our hospital because of abdominal pain and vomiting after barium meal examination. Physical and radiographic examination showed sigmoid colon perforation. Barium sulfate extravasation was noted in the intraperitoneal cavity. We diagnosed the patient with barium peritonitis, and performed Hartmann’s procedure and thorough lavage of the intraperitoneal cavity with 20-L saline. Postoperative blood examination results were not readily improved because of the residual barium in the intraperitoneal and retroperitoneal cavities. We excluded the presence of any other inflammation origin, except that from residual barium. Methylprednisolone 500 mg/body/day was administered for 3 days and the dose was gradually decreased thereafter. The white blood cell count and serum C-reactive protein levels immediately improved to normal levels. Discussion Barium peritonitis is associated with high mortality. Residual barium in the intraperitoneal cavity can cause chemical peritonitis, leading to granuloma formation and ileus, postoperatively. Therefore, complete removal of barium in the abdominal cavity with aggressive drainage and large quantity of saline is necessary to prevent postoperative inflammatory reaction. The use of steroids improves the persistent inflammation caused by residual barium, unless any infectious origins are present, which can worsen with steroid-use. Conclusion Residual barium in the intraperitoneal cavity causes persistent inflammatory reaction in patients with barium peritonitis. The use of steroids is effective for postoperative persistent inflammation due to the residual barium.

Abstract
To understand the roles of pluripotent stem cell-inducing genes in gastric cancer, the expression of Krüppel-like factor 4 (KLF4), Nanog, octamer-binding transcription factor 4 (Oct4), avian myelocytomatosis viral oncogene homolog (c-Myc) and sex-determining region Y-box 2 (SOX2) was examined using the newly developed gastric carcinoma tissue microarray. The associations between the immunohistochemical expression levels of the pluripotency-inducing factors and the clinicopathological data of 108 patients with gastric cancer were analyzed. No associations were identified between the expression levels of the five pluripotency-inducing factors and the tumor-node-metastasis (TNM) classification or clinicopathological characteristics of the patients. In addition, multivariate analysis revealed no association of Nanog, Oct4, SOX2 or c-Myc with the prognosis of the gastric cancer patients; however, low expression of KLF4 was determined to be an independent negative prognostic factor (P=0.0331), particularly in patients who underwent R0 resection (TNM stages 2 and 3; P=0.0048). In summary, low KLF4 expression was found to be negatively associated with overall survival, and may therefore be a useful prognostic marker in gastric cancer patients.

Abstract
OBJECTIVE The utility of quantitative muscle ultrasound as a marker of disease severity in Charcot-Marie-Tooth (CMT) disease subtypes was investigated. METHODS Muscle ultrasound was prospectively performed on 252 individual muscles from 21 CMT patients (9 CMT1A, 8 CMTX1, 4 CMT2A) and compared to 120 muscles from 10 age and gender-matched controls. Muscle ultrasound recorded echogenicity and thickness in representative muscles including first dorsal interosseus (FDI) and tibialis anterior (TA). RESULTS Muscle volume of FDI and thickness of TA correlated with MRC strength. Muscle echogenicity was significantly increased in FDI (65.05 vs 47.09; p<0.0001) and TA (89.45 vs 66.30; p<0.0001) of CMT patients. In TA, there was significantly higher muscle thickness (23 vs 18 vs 16mm; p<0.0001) and lower muscle echogenicity (80 vs 95 vs 108; p<0.0001) in CMT1A compared to CMTX1 and CMT2A. This corresponded to disease severity based on muscle strength (MRC grading CMT1A vs CMTX1 vs CMT2A: 59 vs 48 vs 44; p=0.002). CONCLUSION In CMT, quantitative muscle ultrasound of FDI and TA is a useful marker of disease severity. SIGNIFICANCE The current findings suggest that quantitative muscle ultrasound has potential as a surrogate marker of disease progression in future interventional trials in CMT.

Abstract
While the past 2 decades have witnessed an increasing understanding of amyotrophic lateral sclerosis (ALS) arising from East Asia, particularly Japan, South Korea, Taiwan and China, knowledge of ALS throughout the whole of Asia remains limited. Asia represents >50% of the world population, making it host to the largest patient cohort of ALS. Furthermore, Asia represents a diverse population in terms of ethnic, social and cultural backgrounds. In this review, an overview is presented that covers what is currently known of ALS in Asia from basic epidemiology and genetic influences, through to disease characteristics including atypical phenotypes which manifest a predilection for Asians. With the recent establishment of the Pan-Asian Consortium for Treatment and Research in ALS to facilitate collaborations between clinicians and researchers across the region, it is anticipated that Asia and the Pacific will contribute to unravelling the uncertainties in ALS.
