OBJECTIVE To compare the effect of enteral vs parenteral nutrition in patients with severe acute pancreatitis for clinically relevant outcomes. DATA SOURCES A computerized literature search was performed in the MEDLINE, EMBASE, and Cochrane databases for articles published from January 1, 1966, until December 15, 2006. STUDY SELECTION From 253(More)
BACKGROUND & AIMS There is no consistency between the individual studies in the literature on whether organ failure (OF) or infected pancreatic necrosis (IPN) is the main determinant of severity in acute pancreatitis. We aimed to statistically aggregate the available data and determine the pooled influence of OF and IPN on mortality in patients with acute(More)
BACKGROUND Early endoscopic retrograde cholangiopancreatography (ERCP) should be performed in all patients with acute biliary pancreatitis (ABP) and coexisting acute cholangitis. In patients without cholangitis and predicted mild ABP it is generally accepted that early ERCP should not be performed. Nevertheless, there is a controversy regarding the role of(More)
BACKGROUND Intestinal ischemia is a potentially catastrophic abdominal emergency that presents a significant diagnostic challenge in the critical care setting. We performed a systematic review of the literature to define the diagnostic accuracy of serological markers of intestinal ischemia. METHODS Observational studies on the performance of markers of(More)
OBJECTIVE To develop a new international classification of acute pancreatitis severity on the basis of a sound conceptual framework, comprehensive review of published evidence, and worldwide consultation. BACKGROUND The Atlanta definitions of acute pancreatitis severity are ingrained in the lexicon of pancreatologists but suboptimal because these(More)
BACKGROUND Infectious complications are the main cause of late death in patients with acute pancreatitis. Routine prophylactic antibiotic use following a severe attack has been proposed but remains controversial. On the other hand, nutritional support has recently yielded promising clinical results. The aim of study was to compare enteral vs. parenteral(More)
Artificial nutrition is an inherent part of management in acute pancreatitis. However, there is no consensus regarding the optimal time of the commencement of feeding in these patients. Our aim was to compare the effect of enteral v. parenteral nutrition with regard to the time points when they were administered in the randomised controlled trials. The(More)
BACKGROUND Acute pancreatitis in pregnancy is rare. We report our institutional therapeutic approaches to this disease and its effect on maternal and fetal outcomes. METHODS A retrospective review of medical records of pregnant women admitted to Brigham and Women's Hospital between 1996 and 2006. RESULTS Twenty-one patients, presenting with 34 episodes(More)
BACKGROUND & AIM Acute pancreatitis (AP) and chronic pancreatitis (CP) traditionally have been thought to be distinct diseases, but there is evidence that AP can progress to CP. Little is known about the mechanisms of pancreatitis progression. We performed a meta-analysis to quantify the frequency of transition of AP to CP and identify risk factors for(More)
BACKGROUND Recent studies have added to the controversy regarding the role of endoscopic retrograde cholangiopancreatography (ERCP) in the management of patients with acute biliary pancreatitis. This debate is due in part to a marked difference between the trials regarding the definition of "complication" as an outcome. This study sought to determine the(More)
