| 1 | Effect of precut sphincterotomy on post-endoscopic retrograde cholangiopancreatography pancreatitis:A systematic review and meta-analysis显示文摘AIM:To conduct a systemic review and meta-analysis to investigate the role of early precut technique.Multiple randomized controlled trails(RCTs)have reported conflicting results of the early precut sphincterotomy.METHODS:MEDLINE/PubMed,EMBASE,Cochrane Central Register of Controlled Trials and Database of Systematic Reviews,and recent abstracts from major conference proceedings were searched(June 2013).Randomized and non-randomized studies comparing early precut technique with prolonged standard methods were included.Pooled estimates of post-endoscopic retrograde cholangiopancreatography(ERCP)pancreatitis(PEP),cannulation and adverse events were analyzed by using odds ratio(OR).Random and fixed effects models were used as appropriate.Publication bias was assessed by funnel plots.Heterogeneity among studies was assessed by calculating I2 measure of inconsistency.RESULTS:Seven randomized and seven non-randomized trials met inclusion criteria.Meta-analysis of RCTs showed a decrease trend for PEP with early precut sphincterotomy but was not statistically significant(OR=0.58;95%CI:0.32-1.05;P=0.07).No heterogeneity was noted among the studies with I2 of 0%.CONCLUSION:Early precut technique for common bile duct cannulation decreases the trend of post-ERCP pancreatitis. | Abhishek Choudhary Jessica Winn Sameer Siddique Murtaza Arif Zainab Arif Ghassan M Hammoud Srinivas R Puli Jamal A Ibdah Matthew L Bechtold | 2014 | World Journal of Gastroenterology2014，20，14： | 13 |
| 2 | Hyoscine for polyp detection during colonoscopy: A meta-analysis and systematic review显示文摘AIM: To assess the role of hyoscine for polyp detectionduring colonoscopy.METHODS: Studies(randomized controlled trials orRCTs) that compared the use of hyoscine vs no hyo-scine or placebo for polyp detection during colonoscopywere included in our analysis. A search on multiple da-tabases was performed in September 2013 with searchterms being 'hyoscine and colonoscopy', 'hyoscineand polyp', 'hyoscine and adenoma', 'antispasmoticand colonoscopy', 'antispasmotic and adenoma', and'antispasmotic and polyp'. Jadad scoring was used toassess the quality of studies. The efficacy of hyoscinewas analyzed using Mantel-Haenszel model for polypand adenoma detection with odds ratio(OR). The I2measure of inconsistency was used to assess hetero-geneity(P < 0.05 or I2 > 50%). Statistical analysis was performed by RevMan 5.1. Funnel plots was used to assess publication bias.RESULTS: The search of the electronic databases identified 283 articles. Of these articles, eight published RCTs performed at various locations in Europe, Asia, and Australia were included in our meta-analysis, seven published as manuscripts and one published as an ab-stract(n = 2307). All the studies included patients with a hyoscine and a no hyoscine/placebo group and were of adequate quality(Jadad score ≥ 2). Eight RCTs as-sessed the polyp detection rate(PDR)(n = 2307). The use of hyoscine demonstrated no statistically significant difference as compared to no hyoscine or placebo for PDR(OR = 1.06; 95%CI: 0.89-1.25; P = 0.51). Five RCTs assessed the adenoma detection rate(ADR)(n = 2015). The use of hyoscine demonstrated no statisti-cally significant difference as compared to no hyoscine or placebo for ADR(OR = 1.12; 95%CI: 0.92-1.37; P = 0.25). Furthermore, the timing of hyoscine admin-istration(given at cecal intubation or pre-procedure) demonstrated no differences in PDR compared to no hyoscine or placebo. Publication bias or heterogeneity was not observed for any of the outcomes.CONCLUSION: Hyoscine use in patients undergoing colonoscopy does not appear to significantly increase the detection of polyps or adenomas. | Imran Ashraf Sohail Ashraf Sameer Siddique Douglas L Nguyen Abhishek Choudhary Matthew L Bechtold | 2014 | World Journal of Gastrointestinal Endoscopy2014，6，11： | 0 |
