Goals: To develop an automated method for Adenoma Detection Rate (ADR) calculation and report card generation using common electronic health records (EHRs).

Background: ADR is the most widely accepted colonoscopy quality indicator and is inversely associated with interval colorectal cancer incidence and mortality. However, ADR is difficult to efficiently measure and disseminate, due to need for data integration from distinct electronic databases.

Background: Despite a strong link between Helicobacter Pylori infection and peptic ulcer disease (PUD), rates of testing for H. Pylori in hospitalized patients with PUD remain largely unexplored. We aimed to determine H.

Non-operating room anesthesia (NORA) has grown and continues to expand as a proportion of all anesthesia practice in the United States [1, 2]. While many management processes have been adapted for NORA from the traditional operating room, it is still unclear what scheduling paradigm will maximize efficiency of resource utilization in this arena. In this study, we investigate the impact of tactical a shift from a shared group to individual, provider-specific block allocations for available anesthesia time in an endoscopy suite for adult patients undergoing elective endoscopy procedures at an academic hospital.

Background And Aim: To elucidate the overall risk and risk factors for developing cholangitis following biliary stent placement by endoscopic retrograde cholangiopancreatography (ERCP) and to determine the clinical outcomes of these individuals.

Methods: We performed a retrospective review of 796 patients who had undergone 1127 ERCPs with biliary stent placement between 2007 and 2015 at a single tertiary care center. There were 91 episodes of stent-associated cholangitis (SAC) during the study period.

Background: Well-differentiated neuroendocrine tumors (NET) most frequently arise from the gastrointestinal tract (GI), pancreas, and lung. Patients often present as metastasis with an unknown primary, and the clinical management and outcome depend on multiple factors, including the accurate diagnosis with the tumor primary site. Determining the site of the NET with unknown primary remains challenging.

Background And Study Aims: Choledochoscopy is increasingly performed during endoscopic retrograde cholangiopancreatography (ERCP) for direct bile duct visualization. Choledochoscopy necessitates irrigation of the bile duct with water or saline, which may increase intrabiliary pressure and consequently the risks of bacteremia and cholangitis. The aim of this study was to prospectively evaluate the risk of bacteremia and infectious complications in patients undergoing single-operator choledochoscopy (SOC).

Background: Celiac disease (CD) is associated with hypothyroidism, but the disease prevalence is not thought to be great enough to warrant testing all hypothyroid patients. We hypothesized that hypothyroid patients with concomitant CD would require elevated doses of levothyroxine, and there is a threshold daily dose, above which, hypothyroid patients should be tested for CD.

Methods: Hypothyroid patients presenting to the endoscopy or endocrinology clinics at the University of Vermont Medical Center were included.

Objective: We sought to evaluate if left ventricular filling pressures can be assessed from the esophagus.

Background: The invasive assessment of left ventricular filling pressures is of importance in the evaluation and monitoring of critically ill patients. The left atrium is in very close proximity to the esophagus.

Background: Celiac disease is more common in patients with hypothyroidism. Malabsorption of levothyroxine has not been studied in this population. We sought to determine if levothyroxine dosing was influenced by the presence and treatment of celiac disease.

Background/aims: The Rosemont classification system was designed to standardize the endosonographic assessment of chronic pancreatitis. To determine whether the Rosemont classification system can predict the response to pancreatic enzyme supplementation in patients undergoing endoscopic ultrasound (EUS) evaluation of suspected chronic pancreatitis.

Methods: Sixty-five patients were included with abdominal pain undergoing endosonography for suspected chronic pancreatitis were included.

Background: Earlier detection of pancreatic adenocarcinoma is needed.

Objective: To determine whether early pancreatic neoplasia can be detected in a high-risk population by using CA 19-9 followed by targeted EUS.

Design: Prospective cohort study.
