Background:The most common adverse event of endoscopic retrograde cholangiopancreatography is pancreatitis. Precut sphincterotomy has been regarded as a risk factor. Some authors have stated that early precut may actually reduce post-ERCP pancreatitis risk. However, early precut as a preventive measure has not been compared to other preventive measures, such as pancreatic duct stent placement.Aim: To compare the efficacy of early precut sphincterotomy versus pancreatic duct stent placement in high-risk subjects undergoing endoscopic retrograde cholangiopancreatography for the prevention of post-endoscopic cholangiopancreatography.
Materials and methods:This was a single-blinded, randomized trial that took place in two tertiary referral centers in Buenos Aires, from November 2011 to December 2013. ERCP subjects presented at least one of the following risk factors: female sex, age less than 40 years, clinical suspicion of sphincter of Oddi dysfunction, previous pancreatitis, and/or common bile duct diameter of less than 8 mm. Only those who presented a difficult biliary cannulation were randomized into two groups: those who received early precut sphincterotomy and those in whom persistency of biliary cannulation was intended, with subsequent pancreatic duct stent placement after cholangiography was achieved. The incidence of post-ERCP pancreatitis, as well as other adverse events incidence, was compared.Results: Overall, 101 patients were enrolled, 51 in the pancreatic duct stent group and 50 in the early precut group. Pancreatitis rate was similar in both groups (3.92% vs. 4%, p NS). In all cases, pancreatitis was classified as mild. There were no deaths registered.Conclusion: Early precut was associated with an incidence of adverse events similar to pancreatic duct stent placement.
-Background -Previous evidence trying to assess the risk of celiac disease among dyspeptic patients has been inconclusive, showing in some cases notorious discrepancies. Objective -To determine the prevalence of celiac disease in patients with dyspepsia compared to healthy controls without dyspepsia. Methods -Adult patients under evaluation for dyspepsia were invited to participate. These patients were offered an upper gastrointestinal endoscopy with duodenal biopsies. On the other hand, asymptomatic adult volunteers who performed a preventive visit to their primary care physician were invited to participate and agreed to undertake an upper gastrointestinal endoscopy with duodenal biopsies as well. Those patients with histologic signs of villous atrophy were furtherly evaluated and serological tests were performed in order to determine celiac disease diagnosis. Celiac disease prevalence was compared between groups. Results -Overall, 320 patients with dyspepsia and 320 healthy controls were recruited. There were no significant differences in terms of gender or age between groups. Celiac disease diagnosis was made in 1.25% (4/320) of patients in the dyspepsia group versus 0.62% (2/320) in the control group. Conclusion -Patients with dyspepsia who underwent routine duodenal biopsies did not show an increased risk for celiac disease when compared to healthy individuals. HEADINGS -Celiac disease. Dyspepsia. Endoscopy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
