The EndoRotor, nonthermal, powered endoscopic debridement (PED) instrument (Interscope Inc, Whitinsville, Mass, USA), is a novel device used in the GI tract. It uses adjustable suction and a rotary cutting blade to precisely resect mucosal and submucosal tissue. Our aim was to assess the technical feasibility, safety, and efficacy of PED using the EndoRotor device. This was an Institutional Review Board–approved, multicenter, retrospective review. Patients underwent PED with the EndoRotor device from August 2018 to September 2019 at 4 high-volume U.S. centers. Patient demographics, indication for PED, and procedural and histopathologic data were recorded. Thirty-four patients underwent PED (41 lesions). The most common indications for PED were colon polyps (18, 52.9%) and Barrett's esophagus (8, 23.5%). Most lesions (35, 85.4%) were resected previously for the same indication using standard techniques. Technical success was achieved in 97.6% of lesions (n = 40). Clinical success was achieved in most patients who underwent a follow-up examination (19, 79.2%). Intraprocedural bleeding (in 10 patients) was managed endoscopically; no EndoRotor-related perforations occurred. Three postprocedural adverse events occurred: self-limited chest pain in 1 patient and delayed bleeding in 2. The EndoRotor is a novel, effective, and safe PED device for endoscopic resection of flat and polypoid lesions in the colon and foregut. It may have a promising role in the endoscopic management of naïve and scarred mucosal lesions based on this initial experience. Further prospective studies are needed to clarify its role in endoluminal resection. [ABSTRACT FROM AUTHOR]

Nonalcoholic fatty liver disease (NAFLD) is now the leading cause of chronic liver disease worldwide with a strong association with metabolic syndrome. NAFLD is truly a systemic disease and is associated with a plethora of extra-hepatic manifestations or comorbidities. These are either related to secondary effects of associated obesity or from pathophysiological effects of insulin resistance in NAFLD. Three most common causes of increased morbidity and mortality associated with NAFLD are cardiovascular disease, liver disease, and cancer. In this narrative review, we will discuss comprehensively on cardiovascular disease, type 2 diabetes mellitus, and chronic kidney disease and will also highlight on malignancy especially colorectal cancer, pulmonary disorders including obstructive sleep apnea, endocrine disorders such as hypothyroidism and polycystic ovarian syndrome, dermatological disorders especially psoriasis, and hematological associations including iron overload and susceptibility to thrombosis. In addition to focusing on pathogenesis of these extrahepatic manifestations, we will highlight their clinical implications for physicians in routine clinical practice. Further, there remains an unmet need for safe and effective therapies and examining their benefits on these extra-hepatic manifestations among patients with NAFLD. [ABSTRACT FROM AUTHOR]

Recurrent gastrointestinal bleeding (GIB) is a common complication following left ventricular assist device (LVAD) implantation. Our study aimed to estimate the comparative efficacy of different pharmacologic interventions for the prevention of GIB, through a network meta-analysis (NMA). A total of 13 observational studies comparing six strategies. Among those, 4 were for primary, and 9 were for secondary prevention of GIB. On NMA, thalidomide (Hazard ratio [HR]: 0.016, Credible interval [CrI]I: 0.00053-0.12), omega-3-fatty acid (HR:0.088, CrI: 0.026-0.77), octreotide (HR: 0.17, CrI: 0.0589-0.41) and danazol (HR:0.17, CrI: 0.059-0.41) reduced the risk of GIB. The use of angiotensin-converting enzyme inhibitors/angiotensin II receptor blocker (ACEi/ARB) and digoxin were not associated with any significant reduction. Based on NMA, combining indirect treatment comparisons, thalidomide, danazol, and octreotide treatments were associated with decreased risk of recurrent GIB. Additionally, Omega 3 fatty acids were associated with a lower risk of the primary episode of GIB in the LVAD patient population. [ABSTRACT FROM AUTHOR]
