BACKGROUND EUS is highly sensitive, specific, and cost-effective for localization of pancreatic neuroendocrine tumors. EUS screening of asymptomatic patients with multiple endocrine neoplasia type 1 has not been described. METHODS EUS was used to evaluate all patients with known or suspected pancreatic neuroendocrine tumors. Asymptomatic patients with(More)
OBJECTIVES We investigated which variables independently associated with protection against or development of postendoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP) and severity of PEP. Subsequently, we derived predictive risk models for PEP. METHODS In a case-control design, 6505 patients had 8264 ERCPs, 211 patients had PEP, and 22(More)
BACKGROUND & AIMS Alcohol use and cigarette smoking are associated with various pancreatic diseases, but it is not known whether they associate with post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP). We performed a retrospective case-control study to determine if these activities increase the risk of PEP. METHODS We identified(More)
OBJECTIVES There are many published clinical guidelines for acute pancreatitis (AP). Implementation of these recommendations is variable. We hypothesized that a clinical decision support (CDS) tool would change clinician behavior and shorten hospital length of stay (LOS). METHODS DESIGN/SETTING Observational study, entitled, The AP Early Response(More)
OBJECTIVE To compare patients with chronic pancreatitis (CP) with constant pain patterns to patients with CP with intermittent pain patterns. METHODS This was a prospective cohort study conducted at 20 tertiary medical centers in the USA comprising 540 subjects with CP. Patients with CP were asked to identify their pain from five pain patterns (A-E)(More)
We review important new clinical observations in pancreas divisum (PD) made since 2007. PD is common and has the same prevalence in the general population and idiopathic pancreatitis (IP). Up to 53% of patients with PD and IP have underlying idiopathic chronic pancreatitis (CP), and in rigorous prospective clinical follow-up and/or natural history studies,(More)
Esophageal fully covered self-expandable metal stents (FCSEMS) are indicated for the management of benign and malignant conditions of the esophagus including perforations, leaks, and strictures. FCSEMS are resistant to tissue ingrowth and are removable; however, stent migration occurs in 30–55% of cases. Endoscopic suture fixation of FCSEMS has been(More)
GOALS To describe the short-term and long-term outcomes in 34 consecutive decompensated cirrhotic patients with symptomatic gallbladder disease undergoing transpapillary gallbladder stent (TGS) placement. BACKGROUND Endoscopic TGS placement is a minimally invasive means of treating symptomatic gallbladder disease in poor surgical candidates. STUDY(More)
