This Guideline is an official statement of the European Society of Gastrointestinal Endoscopy (ESGE). It addresses the removal of foreign bodies in the upper gastrointestinal tract in adults. Recommendations Nonendoscopic measures 1 ESGE recommends diagnostic evaluation based on the patient?s history and symptoms. ESGE recommends a physical examination focused on the patient?s general condition and to assess signs of any complications (strong recommendation, low quality evidence). 2 ESGE does not recommend radiological evaluation for patients with nonbony food bolus impaction without complications. We recommend plain radiography to assess the presence, location, size, configuration, and number of ingested foreign bodies if ingestion of radiopaque objects is suspected or type of object is unknown (strong recommendation, low quality evidence). 3 ESGE recommends computed tomography (CT) scan in all patients with suspected perforation or other complication that may require surgery (strong recommendation, low quality evidence). 4 ESGE does not recommend barium swallow, because of the risk of aspiration and worsening of the endoscopic visualization (strong recommendation, low quality evidence). 5 ESGE recommends clinical observation without the need for endoscopic removal for management of asymptomatic patients with ingestion of blunt and small objects (except batteries and magnets). If feasible, outpatient management is appropriate (strong recommendation, low quality evidence). 6 ESGE recommends close observation in asymptomatic individuals who have concealed packets of drugs by swallowing (?body packing?). We recommend against endoscopic retrieval. We recommend surgical referral in cases of suspected packet rupture, failure of packets to progress, or intestinal obstruction (strong recommendation, low quality evidence). Endoscopic measures 7 ESGE recommends emergent (preferably within 2 hours, but at the latest within 6 hours) therapeutic esophagogastroduodenoscopy for foreign bodies inducing complete esophageal obstruction, and for sharp-pointed objects or batteries in the esophagus. We recommend urgent (within 24 hours) therapeutic esophagogastroduodenoscopy for other esophageal foreign bodies without complete obstruction (strong recommendation, low quality evidence). 8 ESGE suggests treatment of food bolus impaction in the esophagus by gently pushing the bolus into the stomach. If this procedure is not successful, retrieval should be considered (weak recommendation, low quality evidence). The effectiveness of medical treatment of esophageal food bolus impaction is debated. It is therefore recommended, that medical treatment should not delay endoscopy (strong recommendation, low quality evidence). 9 In cases of food bolus impaction, ESGE recommends a diagnostic work-up for potential underlying disease, including histological evaluation, in addition to therapeutic endoscopy (strong recommendation, low quality evidence). 10 ESGE recommends urgent (within 24 hours) therapeutic esophagogastroduodenoscop...

Contrary to the original study, the follow-up study suggested that seclusion might be a less restrictive alternative for most patients. The incidence of PTSD seemed lower than expected.

Angiotensin II (Ang II) has been implicated in the pathophysiology of various age-dependent ocular diseases. The purpose of this study was to test the hypothesis that Ang II induces endothelial dysfunction in mouse ophthalmic arteries and to identify the underlying mechanisms. Ophthalmic arteries were exposed to Ang II in vivo and in vitro to determine vascular function by video microscopy. Moreover, the formation of reactive oxygen species (ROS) was quantified and the expression of prooxidant redox genes and proteins was determined. The endothelium-dependent artery responses were blunted after both in vivo and in vitro exposure to Ang II. The Ang II type 1 receptor (AT1R) blocker, candesartan, and the ROS scavenger, Tiron, prevented Ang II-induced endothelial dysfunction. ROS levels and NOX2 expression were increased following Ang II incubation. Remarkably, Ang II failed to induce endothelial dysfunction in ophthalmic arteries from NOX2-deficient mice. Following Ang II incubation, endothelium-dependent vasodilation was mainly mediated by cytochrome P450 oxygenase (CYP450) metabolites, while the contribution of nitric oxide synthase (NOS) and 12/15-lipoxygenase (12/15-LOX) pathways became negligible. These findings provide evidence that Ang II induces endothelial dysfunction in mouse ophthalmic arteries via AT1R activation and NOX2-dependent ROS formation. From a clinical point of view, the blockade of AT1R signaling and/or NOX2 may be helpful to retain or restore endothelial function in ocular blood vessels in certain ocular diseases.
