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.

Objective:
The aim of this systematic review and meta-analysis is to determine summary estimates of the diagnostic accuracy of mean platelet volume for the diagnosis of myocardial infarction among adult patients with angina and/or its equivalents in terms of sensitivity, specificity, diagnostic odds ratio, and likelihood ratios.
Methodology:
The primary search was done through search in electronic databases. Cross-sectional, cohort, and case-control articles studying the diagnostic performance of mean platelet volume in the diagnosis of acute myocardial infarction in adult patients were included in the study. Eligible studies were appraised using well-defined criteria.
Results:
The overall mean MPV value of those with MI (9.702 fl; 95% CI 9.07 – 10.33) was higher than in those of the non-MI control group (8.85 fl; 95% CI 8.23 – 9.46). Interpretation of the calculated t-value of 2.0827 showed that there was a significant difference in the mean MPV values of those with MI and those of the non-MI controls. The summary sensitivity (Se) and specificity (Sp) for MPV were 0.66 (95% CI; 0.59 - 0.73) and 0.60 (95% CI; 0.43 – 0.75), respectively. The pooled diagnostic odds ratio (DOR) was 2.92 (95% CI; 1.90 – 4.50). The positive likelihood ratio of MPV in the diagnosis of myocardial infarction was 1.65 (95% CI; 1.20 – 22.27), and the negative likelihood ratio was 0.56 (95% CI; 0.50 – 0.64).
Conclusion
The intended role for MPV in the diagnostic pathway of myocardial infarction would perhaps be best as a triage tool. MPV values can discriminate between those who have MI and those without. For a patient with angina presenting with elevated MPV values, it is 1.65 times more likely that he has MI. It is implied that the decision to treat a patient with angina or its equivalents as a case of MI could be supported by an elevated MPV value.

5.Association between the Neutrophil-to-lymphocyte Ratio, and Platelet-to-lymphocyte Ratio and Rheumatoid Arthritis and their Correlations with the Disease Activity: A Meta-analysis.
Journal of Rheumatic Diseases 2018;25(3):169-178
OBJECTIVE: This study examined the relationship between neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), mean platelet volume (MPV), and rheumatoid arthritis (RA), to establish a correlation among the NLR, PLR, and MPV and RA activity. METHODS: Medline, Embase, and Cochrane were searched, and a meta-analysis was performed to compare the NLR, PLR, and MPV between RA patients and healthy controls. The correlation coefficients between NLR, PLR, and MPV and the Disease Activity Score 28 (DAS28) in the RA patients were examined. RESULTS: Sixteen studies were included in this meta-analysis. NLR was significantly higher in the RA group (standardized mean difference [SMD], 0.800; 95% confidence interval [CI], 0.542~1.058; p < 0.001). Stratification according to ethnicity revealed a significantly elevated NLR in the RA group in Asian and Turkish populations (SMD, 95% CI: 0.994, 0.418~1.519, p=0.001 and 0.695, 0.443~0.948, p < 0.001, respectively). Subgroup analysis revealed a significantly high NLR in RA, independent of the data type and adjustment for age and/or sex. PLR was also significantly higher in the RA group (SMD, 0.708; 95% CI, 0.401~0.995; p < 0.001), regardless of ethnicity, data type, and adjustment for age and/or sex. In addition, NLR and PLR were positively associated with the RA activity based on the DAS28 (correlation coefficient, 95% CI: 0.277, 0.190~0.359, p < 0.001 and 0.318, 0.197~0.430, p < 0.001, respectively). However, MPV showed no correlation with the RA activity (correlation coefficient, −0.095; 95% CI, −0.435 to 0.269; p=0.615). CONCLUSION: Meta-analysis showed that the NLR and PLR were significantly higher in the RA patients and positively but weakly correlated with the RA activity.

OBJECTIVE: This study sought to evaluate platelet volume indices (mean platelet volume [MPV], platelet distribution width [PDW], and platelet large cell ratio [P-LCR]) in varicocele patients, and compare it with platelet volume parameters in healthy controls. METHODS: This cross-sectional study involved 2 groups: group 1 included 51 varicocele subjects and group 2 consisted of 50 healthy control subjects of similar ages. Peripheral venous blood samples were collected with ethylenediaminetetraacetic acid-K2 anticoagulant between 8:30 AM and 10 AM following an overnight fast. Platelet volume parameters (MPV, PDW, and P-LCR) were measured in both groups within 2 hours of sampling. RESULTS: The mean PDW, MPV, and P-LCR were 13.9+/-2.5%, 10.1+/-1.3 fL, and 27.3+/-7.8% in varicocele patients, respectively, and were 12.6+/-2.4%, 9.3+/-1.1 fL, and 21.9+/-6.4% in the control group, respectively. The mean PDW, MPV, and P-LCR were significantly higher in the varicocele group than the control group. CONCLUSION: The results of the present study suggest that vascular components may play an important role in the pathophysiology of varicocele; therefore, there is a great need for prospective studies to confirm this relationship.

PURPOSE: The relationship between the number and size of platelet in the thrombocytosis period of Kawasaki disease (KD) was analyzed to investigate the risk of thrombosis in KD. METHODS: The number and size of the platelet in patients with KD (n=221) were serially evaluated and the relationship was analyzed. RESULTS: The value of mean platelet volume (MPV) was inversely correlated with the highest number of platelet with r(2)=0.0741, P < 0.001. CONCLUSIONS: Considering the size of the platelet, the vulnerability of thrombosis during the thrombocytosis period of KD might be low.

Gray platelet syndrome (GPS) is one of primary hemostatic disorders with characteristics of moderate bleeding tendency, thrombocytopenia, gray platelet on Wright-Giemsa stained smear and absence of platelet -granule. It is known to be mostly inherited by autosomal dominance but not all. We report a case of gray platelet syndrome diagnosed in a woman with bleeding tendency such as easy bruise and evaluate clinical usefulness of mean platelet component (MPC), mean platelet volume (MPV) and platelet component distribution width (PCDW) using ADVIA 120 (Bayer Diagnostics, NY, USA).
