Relationships of hospitalization outcomes and timing to endoscopy in non-variceal upper gastrointestinal bleeding: A nationwide analysis.

Background: The optimal timing of esophagogastroduodenoscopy (EGD) and the impact of clinico-demographic factors on hospitalization outcomes in non-variceal upper gastrointestinal bleeding (NVUGIB) remains an area of active research.

Aim: To identify independent predictors of outcomes in patients with NVUGIB, with a particular focus on EGD timing, anticoagulation (AC) status, and demographic features.

Methods: A retrospective analysis of adult patients with NVUGIB from 2009 to 2014 was performed using validated ICD-9 codes from the National Inpatient Sample database.

The outcomes and safety of patients undergoing endoscopic retrograde cholangiopancreatography combining a single-use cholangioscope and a single-use duodenoscope: A multicenter retrospective international study.

Background: Duodenoscope-related multidrug-resistant organism (MDRO) infections raise concerns. Disposable duodenoscopes have been recently introduced in the market and approved by regulatory agencies with the aim to reduce the risk of endoscopic retrograde cholangiopancreatography (ERCP) associated infections. The aim of this study was to evaluate the outcome of procedures performed with single-use duodenoscopes in patients with clinical indications to single-operator cholangiopancreatoscopy.

The role and timing of endoscopic retrograde cholangiopancreatography in acute biliary pancreatitis without cholangitis: A nationwide analysis.

Background/purpose: The role and optimal timing of endoscopic retrograde cholangiopancreatography (ERCP) in acute biliary pancreatitis without cholangitis (ABPwoC) remains unclear. Using a large national database, we aimed to examine hospitalization outcomes of patients with ABPwoC as a function of the performance and timing of ERCP.

Methods: This was a retrospective study of adult patients with ABPwoC utilizing the National Inpatient Sample from 2016-2017.

A Puzzling Case of Pouch Pathology.

A 36-year-old man with familial adenomatous polyposis secondary to an adenomatous polyposis coli mutation status post proctocolectomy with ileal pouch-anal anastomosis presented with hematochezia. Pouchoscopy revealed a 4-cm indurated mass in the distal ileal pouch just 17 months after a normal pouchoscopy. Histopathology was diagnostic for Burkitt lymphoma, and the patient achieved complete remission with subsequent chemotherapy.

Best practices for prevention of post-endoscopic retrograde cholangiopancreatography pancreatitis.

Acute pancreatitis is of one the most common gastroenterology-related indications for hospital admissions worldwide. With the widespread reliance on endoscopic retrograde cholangiopancreatography (ERCP) for the management of pancreaticobiliary conditions, post-ERCP pancreatitis (PEP) has come to represent an important etiology of acute pancreatitis. Despite many studies aiming to better understand the pathogenesis and prevention of this iatrogenic disorder, findings have been heterogeneous, and considerable variation in clinical practice exists.

Impact of Readmission for Variceal Upper Gastrointestinal Bleeding: A Nationwide Analysis.

Background: Variceal upper gastrointestinal bleeding (VUGIB) is a common and potentially lethal complication of cirrhosis. Population-based data regarding hospital readmission and other outcomes in VUGIB are limited.

Aim: In a large United States database of patients with VUGIB, we evaluated readmission rates, mortality rates, healthcare resource consumption, and identified predictors of readmission.

Device profile of the EXALT Model D single-use duodenoscope for endoscopic retrograde cholangiopancreatography: overview of its safety and efficacy.

: The management of pancreaticobiliary disorders relies heavily on endoscopic retrograde cholangiopancreatography, which is performed with a duodenoscope. Bacterial colonization of reusable duodenoscopes leading to subsequent infectious outbreaks is well recognized and remains an issue despite efforts to optimize best practices in high-level disinfection. The EXALT Model D duodenoscope (EXALT) (Boston Scientific Corporation, Marlborough, MA) is a single-use device, designed to achieve technical equivalency with reusable devices while eliminating the potential for device-related outbreaks.

The Utility of EUS-FNA to Determine Surgical Candidacy in Patients with Pancreatic Cancer after Neoadjuvant Therapy.

Background: In patients with borderline resectable pancreatic cancer (BRPC) or locally advanced pancreatic cancer (LAPC) who undergo neoadjuvant therapy, CT imaging is the standard of care for restaging. However, differentiating residual tumor from post-treatment inflammation with CT is unreliable. The diagnosis of periarterial soft tissue cuffing (PSTC) near major vessels is key to guiding resectability.

Rapidly progressive neurologic decline and morbilliform rash presenting in a patient with lymphoma.

A 67-year-old male with past medical history of mantle cell lymphoma and atrial fibrillation presented with a truncal rash, bilateral lower extremity weakness, and confusion. Within three days of presentation, his condition rapidly deteriorated with the onset of diffuse flaccid paralysis, aphasia, and severe alteration in mental status. Initial results from serum studies, lumbar puncture, magnetic resonance imaging, and electroencephalogram were not diagnostic.

Barriers to Follow-up Colonoscopies for Patients With Positive Results From Fecal Immunochemical Tests During Colorectal Cancer Screening.

Background & Aims: Colorectal cancer is common yet largely preventable. The fecal immunochemical test (FIT) is a highly recommended screening method, but patients with positive results must receive a follow-up colonoscopy to determine if they have precancerous or cancerous lesions. We characterized colonoscopic follow-up evaluations and reasons for lack of follow-up in a Veterans Affairs (VA) cohort.

A Challenging Case of Severe Ulcerative Colitis following the Initiation of Secukinumab for Ankylosing Spondylitis.

Secukinumab is an interleukin-17 inhibitor used for the treatment of ankylosing spondylitis (AS), psoriasis, and psoriatic arthritis. The risk of exacerbating underlying inflammatory bowel disease (IBD) in patients being treated with secukinumab for other conditions is controversial. We document a patient with AS and previously undiagnosed IBD, found to be in a severe ulcerative colitis flare shortly after receiving the loading dose of secukinumab.

A multicenter evaluation of a new EUS core biopsy needle: Experience in 200 patients.

Background And Objectives: We present a multicenter study of a new endoscopic ultrasound-guided fine-needle biopsy (EUS-FNB) needle (Acquire, Boston Scientific, Natick, MA). The aim of the study was to analyze the needle's clinical performance when sampling solid lesions and to assess the safety of this device.

Methods: We performed a multicenter retrospective study of patients undergoing EUS-FNB during July 1-November 15, 2016.

Genome mapping on nanochannel arrays for structural variation analysis and sequence assembly.

We describe genome mapping on nanochannel arrays. In this approach, specific sequence motifs in single DNA molecules are fluorescently labeled, and the DNA molecules are uniformly stretched in thousands of silicon channels on a nanofluidic device. Fluorescence imaging allows the construction of maps of the physical distances between occurrences of the sequence motifs.
