来源: BMC Gastroenterol. 2009年9卷41页
Some people who suffer an upper gastrointestinal bleed or perforation die. The mortality rate was estimated at 12% in studies published before 1997, but a systematic survey of more recent data is needed. Better treatment is likely to have reduced mortality. An estimate of mortality is helpful in explaining to patients the risks of therapy, especially with NSAIDs.

来源: Gastroenterology. 2007年133卷3期825-34页
Several randomized controlled trials have compared a transjugular intrahepatic portosystemic shunt (TIPS) with large-volume paracentesis in cirrhotic patients with refractory ascites. Although all agree that TIPS reduces the recurrence rate of ascites, survival is controversial. The aim of this study was to compare the effects of TIPS and large-volume paracentesis in cirrhotic patients with refractory ascites by means of meta-analysis of individual patient data from 4 randomized controlled trials.
391. Coffee consumption and risk of liver cancer: a meta-analysis.
Mounting evidence indicates that coffee drinking may protect against liver injury and lower the risk of liver cancer. We quantitatively assessed the relation between coffee consumption and the risk of liver cancer in a meta-analysis of epidemiologic studies.

Knowledge of the placebo outcomes and understanding specific study features that influence these outcomes is important for designing future clinical trials evaluating therapy of ulcerative colitis (UC). The aims of this study were to estimate the placebo rates of remission and response in placebo-controlled, randomized clinical trials for active UC and to identify factors influencing these rates.
394. Folate intake, MTHFR polymorphisms, and risk of esophageal, gastric, and pancreatic cancer: a meta-analysis.
Increasing evidence suggests that a low folate intake and impaired folate metabolism may be implicated in the development of gastrointestinal cancers. We conducted a systematic review with meta-analysis of epidemiologic studies evaluating the association of folate intake or genetic polymorphisms in 5,10-methylenetetrahydrofolate reductase (MTHFR), a central enzyme in folate metabolism, with risk of esophageal, gastric, or pancreatic cancer.

Steatosis is a frequent histologic finding in chronic hepatitis C (CHC), but it is unclear whether steatosis is an independent predictor for liver fibrosis. We evaluated the association between steatosis and fibrosis and their common correlates in persons with CHC and in subgroup analyses according to hepatitis C virus (HCV) genotype and body mass index.
399. Association of 6-thioguanine nucleotide levels and inflammatory bowel disease activity: a meta-analysis.
作者: Mark T Osterman.;Rabi Kundu.;Gary R Lichtenstein.;James D Lewis.
来源: Gastroenterology. 2006年130卷4期1047-53页
6-Thioguanine nucleotide (6-TGN) levels have been proposed to correlate with inflammatory bowel disease (IBD) activity among patients treated with azathioprine or 6-mercaptopurine (6-MP). Previous studies, most with small sample sizes, yielded conflicting conclusions. Our aim was to pool the available data to provide a more precise estimate of the association between 6-TGN levels and IBD activity.
400. Uncovered transjugular intrahepatic portosystemic shunt for refractory ascites: a meta-analysis.
作者: Gennaro D'Amico.;Angelo Luca.;Alberto Morabito.;Roberto Miraglia.;Mario D'Amico.
来源: Gastroenterology. 2005年129卷4期1282-93页
Several trials showed that uncovered transjugular intrahepatic portosystemic shunt (TIPS) is superior to paracentesis for the control of refractory ascites. However, the results for encephalopathy and mortality were not consistent across trials. We performed a systematic review of randomized controlled trials of TIPS for refractory ascites to assess the overall treatment effects and to explore potential reasons of heterogeneity.
