A Multicenter Study of Left Ventricular Assist Device-Related Gastrointestinal Bleeding.

Introduction: Continuous left ventricular assist devices (LVADs) offer hemodynamic support in advanced and decompensated heart failure but are often complicated by gastrointestinal bleeding (GIB) in medically fragile patients.

Methods: We performed a retrospective analysis of 475 consecutive patients who underwent LVAD implantation at the Massachusetts General Hospital and Tufts Medical Center from 2008 to 2019 and identified 128 patients with clinically significant GIB. Clinical characteristics of each bleeding event, including procedures and interventions, were recorded.

Co-existing inflammatory bowel disease and Barrett's esophagus is associated with esophageal dysplasia: a propensity score-matched cohort.

 Barrett's esophagus (BE) and inflammatory bowel disease (IBD) predispose to the development of dysplasia and cancer. It is unclear if the inflammatory cascade seen in IBD affects disease progression in BE. We aimed to determine if patients with BE who have co-existing IBD had a higher risk of dysplasia, nodular disease, or longer segments than BE patients without IBD.

Simplified/Same Day(s)-GOLF as First-line Treatment of Metastatic Carcinoma of Unknown Primary (CUP), Suggestive of Pancreatobiliary Tumors.

Background: Carcinoma of unknown primary represents a therapeutic challenge in oncological practice. Evidence lacks to support particular chemotherapy selection and empirical therapies are commonly extrapolated from data on patients where primary tumor site is known. Gemcitabine, Oxaliplatin, Leucovorin and 5-Fluorouracil was previously developed to treat pancreatic cancer.

In vivo characterization of colonic thermal injury caused by argon plasma coagulation.

Background: Argon plasma coagulation has been rapidly accepted for endoscopic obliteration of vascular lesions and superficial tumors. Depth of injury is thought to be limited through preferential discharge of energy to nondesiccated tissue. However, argon plasma coagulation-induced injury has not been well characterized.
