NCT02776709
Cholangioscopy, or direct visualization of the bile ducts was first documented in the late 1970s and has made many advances over the last few decades. The advent of mother-baby scopes allowed for both diagnostic and therapeutic procedures, though the early scopes were often fragile, and cumbersome due to the need for two endoscopists. Ultraslim endoscopes later became popular as a method to digitally view the bile ducts, however, often needed guide-wire or balloon-assistance to allow for cannulation. Other disadvantages of these systems included limited steerability, and poor irrigation capabilities. The advent of Spyglass, a single-operator peroral cholangioscopy method allowed for a fiberoptic, catheter-based system that could be easily used for diagnostic and therapeutic purposes in the biliary system. However, image quality was often lacking due to the fiberoptic technology. The new digital Spyglass system rectifies this inadequacy by introducing a digital sensor for better image quality, which will allow for better visualization and diagnosis of indeterminate strictures. Furthermore, modification of the scope platform allows for efficient use, reliable directionality of the scope tip, and improved ease of passage of accessories during therapeutic procedures such clearing stones or stent placement.
NCT04368000
Acute respiratory distress syndrome (ARDS) is a major complication among patients with severe disease. In a report of 138 patients with COVID-19, 20% developed ARDS at a median of 8 days after the onset of symptoms, with 12.3% of patients requiring mechanical ventilation. Efficacious therapies are desperately needed. Supportive care combined with intermittent prone positioning may improve outcomes. Prone positioning (PP) of patients with severe ARDS (when combined with other lung-protective ventilation strategies) is associated with a significant mortality benefit. In addition, PP for \>12 hours in severe ARDS is strongly recommended by clinical practice guidelines. The aim of this study is to compare the outcomes of prone positioning versus usual care positioning in non-intubated patients hospitalized for COVID-19.
