BACKGROUND: Transfusion thresholds for acute upper gastrointestinal bleeding are controversial. So far, only three small, underpowered studies and one single-centre trial have been done. Findings from the single-centre trial showed reduced mortality with restrictive red blood cell (RBC) transfusion. We aimed to assess whether a multicentre, cluster randomised trial is a feasible method to substantiate or refute this finding. METHODS: In this pragmatic, open-label, cluster randomised feasibility trial, done in six university hospitals in the UK, we enrolled all patients aged 18 years or older with new presentations of acute upper gastrointestinal bleeding, irrespective of comorbidity, except for exsanguinating haemorrhage...

BACKGROUND: It is generally accepted that patients following an episode of diverticulitis should have additional colonoscopy screening to rule out a colorectal malignancy. We aimed to investigate the rate of CRC found by colonoscopy after an attack of uncomplicated diverticulitis. METHODS: MEDLINE, Embase, and Cochrane databases were searched systematically for clinical trials or observational studies on colonic evaluation by colonoscopy after the initial diagnosis of acute uncomplicated diverticulitis, followed by hand-searching of reference lists...

IMPORTANCE: Diverticulitis is a common disease. Recent changes in understanding its natural history have substantially modified treatment paradigms. OBJECTIVE: To review the etiology and natural history of diverticulitis and recent changes in treatment guidelines. EVIDENCE REVIEW: We searched the MEDLINE and Cochrane databases for English-language articles pertaining to diagnosis and management of diverticulitis published between January 1, 2000, and March 31, 2013...

OBJECTIVES: Acute mesenteric ischemia is an infrequent cause of abdominal pain in emergency department (ED) patients; however, mortality for this condition is high. Rapid diagnosis and surgery are key to survival, but presenting signs are often vague or variable, and there is no pathognomonic laboratory screening test. A systematic review and meta-analysis of the available literature was performed to determine diagnostic test characteristics of patient symptoms, objective signs, laboratory studies, and diagnostic modalities to help rule in or out the diagnosis of acute mesenteric ischemia in the ED...

BACKGROUND: The hemoglobin threshold for transfusion of red cells in patients with acute gastrointestinal bleeding is controversial. We compared the efficacy and safety of a restrictive transfusion strategy with those of a liberal transfusion strategy. METHODS: We enrolled 921 patients with severe acute upper gastrointestinal bleeding and randomly assigned 461 of them to a restrictive strategy (transfusion when the hemoglobin level fell below 7 g per deciliter) and 460 to a liberal strategy (transfusion when the hemoglobin fell below 9 g per deciliter)...

BACKGROUND/AIMS: Measurement of serum lactate remains the most frequently applied laboratory investigation to diagnose acute mesenteric (intestinal) ischemia. The present review aims at critically questioning the widespread measurement of serum lactate to diagnose acute mesenteric ischemia in clinical practice and at drawing attention to more novel markers of intestinal ischemia. METHODS: An electronic search of multiple databases was performed with the key words 'lactate', 'marker', 'mesenteric', 'intestinal' and 'ischemia' to detect all relevant studies...

Bleeding from gastroesophageal varices is a frequent complication of cirrhosis. Mortality from a variceal bleeding episode has decreased in the last 2 decades from 40% to 15 to 20% due to the implementation of effective treatments and improvement in the general medical care. Initial treatment should include adequate fluid resuscitation and transfusion to maintain hemoglobin around 7 to 8 g/dL, and prophylactic antibiotics (norfloxacin or ceftriaxone). It is currently recommended that a vasoactive drug be started as soon as variceal bleeding is suspected...

CONTEXT: Emergency physicians must determine both the location and the severity of acute gastrointestinal bleeding (GIB) to optimize the diagnostic and therapeutic approaches. OBJECTIVES: To identify the historical features, symptoms, signs, bedside maneuvers, and basic laboratory test results that distinguish acute upper GIB (UGIB) from acute lower GIB (LGIB) and to risk stratify those patients with a UGIB least likely to have severe bleeding that necessitates an urgent intervention...

BACKGROUND: The standard of care for acute uncomplicated diverticulitis today is antibiotic treatment, although there are no controlled studies supporting this management. The aim was to investigate the need for antibiotic treatment in acute uncomplicated diverticulitis, with the endpoint of recovery without complications after 12 months of follow-up. METHODS: This multicentre randomized trial involving ten surgical departments in Sweden and one in Iceland recruited 623 patients with computed tomography-verified acute uncomplicated left-sided diverticulitis...

BACKGROUND: Nasogastric lavage (NGL) is often performed early in the management of GI bleeding. This practice assumes that NGL results can assist with timely risk stratification and management. OBJECTIVE: We performed a retrospective analysis to test whether NGL is associated with improved process measures and outcomes in GI bleeding. DESIGN: Propensity-matched retrospective analysis. SETTING: University-based Veterans Affairs medical center...

BACKGROUND: Antibiotic prophylaxis seems to decrease the incidence of bacterial infections in patients with cirrhosis and upper gastrointestinal bleeding and is considered standard of care. However, there is no updated information regarding the effects of this intervention. AIM: To assess the benefits and harms of antibiotic prophylaxis in cirrhotic patients with gastrointestinal bleeding by performing a systematic review of randomised trials. METHODS: We searched The Cochrane Hepato-Biliary Group Controlled Trials Register, The Cochrane Central Register of Controlled Trials in The Cochrane Library, MEDLINE, EMBASE and Science Citation Index EXPANDED until June 2010...

OBJECTIVES: The utility of nasogastric aspiration and lavage in the emergency management of patients with melena or hematochezia without hematemesis is controversial. This evidence-based emergency medicine review evaluates the following question: does nasogastric aspiration and lavage in patients with melena or hematochezia and no hematemesis differentiate an upper from lower source of gastrointestinal (GI) bleeding? METHODS: MEDLINE, EMBASE, the Cochrane Library, and other databases were searched...
