Randomised trials with antacids for preventing oesophagogastric variceal bleeding and bleeding in cirrhotic patients could not be found. Valid evidence for or against the use of antacids for preventing oesophagogastric variceal bleeding and bleeding in cirrhotic patients is lacking.
閱讀完整摘要
Ruptured gastroesophageal varices are the most severe and frequent cause of gastrointestinal bleeding in cirrhotic patients, leading to death in 5% to 8% of patients during the first 48 hours and oesophagogastric varices account for 60% to 80% of first bleeding in patients with portal hypertension. Antacids are often used for emergency treatment of bleeding oesophageal varices in patients with cirrhosis of the liver.
目的
To evaluate the beneficial and harmful effects of antacids for preventing oesophagogastric bleeding and rebleeding.
搜尋策略
We planned to identify relevant randomised clinical trials by searching The Cochrane Hepato-Biliary Group Controlled Trials Register (June 2007), the Cochrane Central Register of Controlled Trials (CENTRAL) in The Cochrane Library (Issue 2, 2007), MEDLINE (1950 to June 2007), EMBASE (Excerpta Medica Database) (1980 to June 2007), and the Science Citation Index Expanded (SCI-EXPANDED) (1945 to June 2007). Additional randomised trials were sought from the reference lists of the trials found and reviews identified by the electronic searches.
選擇標準
We planned to include randomised clinical trials.
資料收集與分析
We planned to summarise data using Cochrane Collaboration methodologies.
主要結果
We could not find any randomised clinical trials on antacids for preventing oesophagogastric variceal bleeding and bleeding in cirrhotic patients.
作者結論
It is not possible to determine whether antacids are beneficial or harmful for preventing oesophagogastric variceal bleeding and rebleeding in cirrhotic patients since randomised clinical trials investigating this question are lacking.
