1Effect of preoperative biliary drainage on outcome of classical pancreaticoduodenectomy显示文摘AIM: To investigate the role of preoperative biliary drainage (PBD) in the outcome of classical pancreaticodu odenectomy. METHODS: A 10-year retrospective data analysis was performed on patients (n = 48) undergoing pancreaticoduodenectomy from March 1994 to March 2004 in department of surgery at SMS medical college, Jaipur, India. Demographic variables, details of preoperative stenting, operative procedure and post operative complications were noted. RESULTS: Preoperative biliary drainage was performed in 21 patients (43.5%). The incidence of septic complications was significantly higher in patients with biliary stent placement (P < 0.05, 0 vs 4). This group of patients also had a significantly higher minor biliary leak rate. Mortality and hospital stay in each group was comparable. CONCLUSION: Within this study population the use of PBD by endoscopic stenting was associated with a high incidence of infective complications. These findings do not support the routine use of biliary stenting in patients prior to pancreatico-duodenectomy.Chandra Shekhar Bhati Chandrashekhar Kubal Pankaj Kumar Sihag Ankur Atal Gupta Raj Kamal Jenav Nicholas G Inston Jagdish M Mehta 2007World Journal of Gastroenterology2007,13,8:12
2Correlation between KCNQ1 and KCNJ11 gene polymorphisms and type 2 and posttransplant diabetes mellitus in the Asian Indian population显示文摘Type 2 diabetes mellitus(T2DM)and post-transplant diabetes mellitus(PTDM)share a common pathophysiology.However,diabetes mellitus is a complex disease,and T2DM and PTDM have different etiologies.T2DM is a metabolic disorder,characterized by persistent hyperglycemia,whereas PTDM is a condition of abnormal glucose tolerance,with variable onset after organ transplant.The KCNQ1 and KCNJ11 gene encode potassium channels,which mediate insulin secretion from pancreatic b-cells,and KCN gene mutations are correlated with the development of diabetes.However,no studies have been carried out to establish an association between KCNQ1 and KCNJ11 gene polymorphisms and T2DM and PTDM.Therefore,our study was aimed at the identification of the role of KCNQ1 and KCNJ11 gene polymorphisms associated with T2DM and the risk of developing PTDM in the Asian Indian population.We have carried out a caseecontrol study including 250 patients with T2DM,250 control subjects,42 patients with PTDM and 98 subjects with non-PTDM.PCR-RFLP analysis was carried out following the isolation of genomic DNA from EDTA-blood samples.The results of the present study reveal that two single nucleotide polymorphisms(rs2283228 and rs5210,of the KCNQ1 and KCNJ11 genes,respectively)are associated with both T2DM and PTDM.The results of our study suggest a role of KCNQ1 and KCNJ11 gene variants in the increased risk of T2DM and PTDM in the Asian Indian population.Imran Ali Khan Kiran Kumar Vattam Parveen Jahan Kamal Kiran Mukkavali Qurratulain Hasan Pragna Rao 2015Genes & Diseases2015,2,3:6
3Predicting the presence of adenomatous polyps during colonoscopy with National Cancer Institute Colorectal Cancer Risk-Assessment Tool显示文摘AIM To evaluate the National Cancer Institute(NCI)Colorectal Cancer(CRC)Risk Assessment Tool as a predictor for the presence of adenomatous polyps(AP) found during screening or surveillance colonoscopy.METHODS This is a retrospective single center observational study.We collected data of adenomatous polyps in each colonoscopy and then evaluated the lifetime CRC risk.We calculated the AP prevalence across risk score quintiles,odds ratios of the prevalence of AP across risk score quintiles,area under curves(AUCs)and Youden’s indexes to assess the optimal risk score cut off value for AP prevalence status.RESULTS The prevalence of AP gradually increased throughout the five risk score quintiles:i.e.,27.63%in the first and 51.35%in the fifth quintile.The odd ratios of AP prevalence in the fifth quintile compared to the first and second quintile were 2.76[confidence interval(CI):1.71-4.47]and 2.09(CI:1.32-3.30).The AUC for all patients was 0.62(CI:0.58-0.66).Youden’s Index indicated the optimal risk score cutoff value discriminating AP prevalence status was 3.60.CONCLUSION Patients with the higher NCI risk score have higher risk of AP and subsequent CRC;therefore,measures to increase the effectiveness of CRC detection in these patients include longer withdrawal time,early surveillance colonoscopy,and choosing flexible colonoscopy over other CRC screening modalities.Hassan Tariq Muhammad Umar Kamal Harish Patel Ravi Patel Muhammad Ameen Shehi Elona Maram Khalifa Sara Azam Aiyi Zhang Kishore Kumar Ahmed Baiomi Danial Shaikh Jasbir Makker 2018World Journal of Gastroenterology2018,24,34:3
