A reduction of the hepatic venous pressure gradient (HVPG) to </=12 mm Hg or by >/=20% of baseline prevents variceal bleeding in cirrhosis. Because some inconsistent data have argued against the clinical application of these hemodynamic targets, we performed a systematic review of available studies from the Cochrane Library and MEDLINE.

Mucoceles resulting from cystadenomas of the appendix are uncommon. Although rare, rupture of the mucoceles can occur with or without causing any abdominal complaint. There are several reports associating colonic malignancy with cystadenomas of the appendix. Herein, we report an unusual and interesting case of right inguinal hernia associated with left colon cancer.
1768. AGA Institute medical position statement on the use of endoscopic therapy for gastroesophageal reflux disease.
This document presents the official recommendations of the AGA Institute on "Endoscopic Therapy for Gastroesophageal Reflux Disease." It was approved by the Clinical Practice and Economics Committee on June 20, 2006, and by the AGA Institute Governing Board on July 24, 2006.
1769. Will screening colonoscopy disappear and transform gastroenterology practice? Threats to clinical practice and recommendations to reduce their impact: report of a consensus conference conducted by the AGA Institute Future Trends Committee.
The AGA Institute Future Trends Committee (FTC) developed this report based on a consensus conference it convened on April 1-2, 2006, in Washington, DC. The report was prepared for the FTC by Carol Regueiro, MD, a medical writer under contract to the AGA Institute, and Michael Stolar, PhD, staff liaison to the FTC. It was approved by the FTC on July 12, 2006, and accepted by the AGA Institute Governing Board on July 22, 2006. This report reflects the panel's assessment of information available at the time of the conference. Readers should view this report in the context of data that will continue to accumulate and facts that may change after its creation.
1770. 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.
1775. Limited value of alarm features in the diagnosis of upper gastrointestinal malignancy: systematic review and meta-analysis.

来源: Gastroenterology. 2006年131卷2期390-401; quiz 659-60页
Alarm features such as dysphagia, weight loss, or anemia raise concern of an upper gastrointestinal malignancy in patients with dyspepsia. The aim of this study was to determine the diagnostic accuracy of alarm features in predicting malignancy by performing a metaanalysis based on the published literature.

1779. The emerging roles of hydrogen sulfide in the gastrointestinal tract and liver.

Hydrogen sulfide, like nitric oxide, was best known as a toxic pollutant before becoming recognized as a key regulator of several physiologic processes. In recent years, evidence has accumulated to suggest important roles for hydrogen sulfide as a mediator of several aspects of gastrointestinal and liver function. Moreover, alterations in hydrogen sulfide production could contribute to disorders of the gastrointestinal tract and liver. For example, nonsteroidal anti-inflammatory drugs can reduce production of hydrogen sulfide in the stomach, and this has been shown to contribute to the generation of mucosal injury. Hydrogen sulfide has also been shown to play a key role in modulation of visceral hyperalgesia. Inhibitors of hydrogen sulfide synthesis and drugs that can generate safe levels of hydrogen sulfide in vivo have been developed and are permitting interventional studies in experimental models and, in the near future, humans.
