Enteral Stents

Enteral stents are tubular devices that can reestablish the patency of the gastrointestinal (GI) lumen in the setting of high-grade obstruction. Although they have been more commonly used in the palliation of malignant obstruction, they now have expanding roles for benign luminal strictures and stenoses. Familiarity with the indications and contraindications for enteral stent placement can enable consideration of a less invasive and morbid therapeutic option for many patients with symptomatic obstructions. The development of self-expandable metal stents and the subsequent emergence of lumen-apposing coaxial metal stents have expanded the role of enteral stents in the management of various GI disorders. This review contains 49 references, 5 figures, and 5 tables. Key Words:coaxial, enteral, gastrointestinal malignancy, lumen-apposing, obstruction, palliation, stent

Diabetes And Obesity

Increasing worldwide prevalence of type 2 diabetes mellitus and its accompanying pathologies such as obesity, arterial hypertension and dyslipidemia represents one of the most important challenges of current medicine. Despite intensive efforts, high percentage of patients with type 2 diabetes does not achieve treatment goals and struggle with increasing body weight and poor glucose control. While novel classes of antidiabetic medications such as incretin-based therapies and gliflozins have some favorable characteristics compared to older antidiabetics, the only therapeutic option shown to substantially modify the progression of diabetes or to achieve its remission is bariatric surgery. Its efficacy in the treatment of diabetes is well established, but the exact underlying modes of action are still only partially described. They include restriction of food amount, enhanced passage of chymus into distal part of small intestine with subsequent modification of gastrointestinal hormones and bile acids secretion, neural mechanisms, changes in gut microbiota and many other possible mechanisms underscoring the importance of the gut in the regulation of glucose metabolism. In addition to bariatric surgery, less-invasive endoscopic methods based on the principles of bariatric surgery were introduced and showed promising results. This review highlights the role of the intestine in the regulation of glucose homeostasis focusing on the mechanisms of action of bariatric and especially endoscopic methods of the treatment of diabetes. A better understanding of these mechanisms may lead to less invasive endoscopic treatments of diabetes and obesity that may complement and widen current therapeutic options.

Colonic Stent

AbstractColonic self-expandable metal stents (SEMS) are widely used as palliation for malignant obstruction. The conventional method involves using a forward-viewing endoscope as part of the procedure. Sometimes, however, the sharp angle of the stricture poses difficulty in evaluating the stricture, so a guidewire is placed across the stricture. Here, we present a case where a side-viewing endoscope was employed for colonic stent placement and propose its use in patients with sharp bends to increase success.
