Upper gastrointestinal bleeding (UGIB) is a common medical emergency, with a reported mortality of 2-10%[1]. It is defined as hemorrhage originating from anywhere between the esophagus and the ligament of Treitz. It can present with hematemesis, melena, or hematochezia. Feasibility/Equipment: […]
Ultrasound (Doppler)
Ultrasound (US) can be used for assessment of several aspects of GI function: estimate dimensions and characteristics of different structures (diameter of different parts of GI tract, thickness of intestinal wall, presence and amount of free fluid), estimate presence and […]
Refractance spectro-photometry
Refractance spectro-photometry is a technique for measuring the amount of light reflected from the surface of a material as a function of wavelength1. It can be used to assess the colorimetric reaction of a substance, such as a biomarker, in […]
Lower GI Bleeding
Lower GI Bleeding Domain: Description: Lower gastrointestinal (GI) bleeding is any bleeding with a source distal to the ligament of Treitz. The clinical manifestation and outcome varies depending on the severity (i.e., from occult to massive), the site of bleeding […]
Infrared Spectroscopy
Infrared spectroscopy (IR) is a technique used to identify and study the chemical bonds and functional groups in molecules. It works by measuring the absorption or transmission of infrared radiation by a sample, which is related to the vibrational modes […]
Gastrointestinal Tonometry
Gastrointestinal tonometry is a diagnostic technique that uses the diffusion of carbon dioxide (CO2) from the surrounding tissue into the gastric lumen to estimate the perfusion and oxygenation of the gut. The technique involves the insertion of a thin, flexible […]
