This article examines use of the Doppler endoscopic probe (DEP) for risk stratification and as a guide to definitive hemostasis of nonvariceal upper gastrointestinal (NVUGI) bleeding and colonic diverticular hemorrhage. Studies report that lesions with high-risk stigmata of recent hemorrhage (SRH) have a higher rate of a positive DEP signal compared with those without such SRH. Lesions with a persistently positive DEP signal after endoscopic hemostasis have a higher 30-day rebleeding rate. Studies document arterial blood flow underneath stigmata of recent hemorrhage as a risk factor for rebleeding of focal nonvariceal gastrointestinal lesions. With DEP probe as a guide, rates of definitive endoscopic hemostasis and clinical outcomes are improved compared with standard visually guided treatment.

D016558 Hemostasis, Endoscopic Control of bleeding performed through the channel of the endoscope. Techniques include use of lasers, heater probes, bipolar electrocoagulation, and local injection. Endoscopic hemostasis is commonly used to treat bleeding esophageal and gastrointestinal varices and ulcers. Endoscopic Hemostasis,Endoscopic Hemostases,Hemostases, Endoscopic
D041981 Gastrointestinal Tract Generally refers to the digestive structures stretching from the MOUTH to ANUS, but does not include the accessory glandular organs (LIVER; BILIARY TRACT; PANCREAS). Digestive Tract,GI Tract,Digestive Tracts,GI Tracts,Gastrointestinal Tracts
D018608 Ultrasonography, Doppler Ultrasonography applying the Doppler effect, with frequency-shifted ultrasound reflections produced by moving targets (usually red blood cells) in the bloodstream along the ultrasound axis in direct proportion to the velocity of movement of the targets, to determine both direction and velocity of blood flow.

D019160 Endosonography Ultrasonography of internal organs using an ultrasound transducer sometimes mounted on a fiberoptic endoscope. In endosonography the transducer converts electronic signals into acoustic pulses or continuous waves and acts also as a receiver to detect reflected pulses from within the organ. An audiovisual-electronic interface converts the detected or processed echo signals, which pass through the electronics of the instrument, into a form that the technologist can evaluate. The procedure should not be confused with ENDOSCOPY which employs a special instrument called an endoscope. The "endo-" of endosonography refers to the examination of tissue within hollow organs, with reference to the usual ultrasonography procedure which is performed externally or transcutaneously.
