Lesions, polyps and other abnormalities in the gastrointestinal (GI) tract have a different composition compared to the normal mucose. The investigators plan to gather spectroscopic information from these features. Characterizing their unique spectrums, may help to enhance the detection and identification of these objects during endoscopy.

This study is being done to see if a new approach to repair perforated ulcers in the stomach (holes in the stomach) or the first part of the intestine will work as well or better than the ...
Endoscopic Esophageal Myotomy (POEM), the research procedure, splits the lower esophageal sphincter muscle fibers from the inside of the esophagus, avoiding several abdominal incisions (be...
Previous studies have shown that histological changes in the gastric mucosa between obese and non-obese individuals do exist. Understanding these histological differences (between obese an...
A Phase 1B study of the efficacy of a topically-administered 7-amino acid peptide labeled with a near-infrared fluorophore Cy5 for detecting neoplastic areas of the colon is proposed. The ...
To investigate the adjunctive role of “Capsule Endoscope” in continuous endoscopic monitoring and early detection of recurrent ulcer bleeding after endoscopic therapy in patients prese...
We report, to the best of our knowledge, a novel approach for generating broadband mid-infrared (mid-IR) light by implementing a dual-channel scheme in a synchronously pumped optical parametric oscill...
Residual fluid within endoscope working channels after reprocessing may promote growth of pathogens. Current reprocessing guidelines therefore recommend endoscope drying with administration of forced ...
A double D-shaped hole optical fiber coated with graphene is proposed as a polarizer at the wavelength of 1.55 μm. As the planar surfaces of D-shaped holes are both coated with graphene, the interac...
Two-dimensional (2D) van der Waals layered materials possess innate advantages as integrable sensors, due to their thinness, flexibility and sensitivity. They can be seamlessly integrated onto surface...
The electrostatic gating defined channel in graphene forms a charge carrier guider. We theoretically investigated electronic transport properties of a single channel and an Aharanov-Bohm (AB) interfer...
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.
Incision of Oddi's sphincter or Vater's ampulla performed by inserting a sphincterotome through an endoscope (DUODENOSCOPE) often following retrograde cholangiography (CHOLANGIOPANCREATOGRAPHY, ENDOSCOPIC RETROGRADE). Endoscopic treatment by sphincterotomy is the preferred method of treatment for patients with retained or recurrent bile duct stones post-cholecystectomy, and for poor-surgical-risk patients that have the gallbladder still present.
Endoscopic examination, therapy or surgery of the female pelvic viscera by means of an endoscope introduced into the pelvic cavity through the posterior vaginal fornix.
The use of light interaction (scattering, absorption, and fluorescence) with biological tissue to obtain morphologically based information. It includes measuring inherent tissue optical properties such as scattering, absorption, and autofluorescence; or optical properties of exogenous targeted fluorescent molecular probes such as those used in optical MOLECULAR IMAGING, or nontargeted optical CONTRAST AGENTS.
A TEXTILE fiber obtained from the pappus (outside the SEEDS) of cotton plant (GOSSYPIUM). Inhalation of cotton fiber dust over a prolonged period can result in BYSSINOSIS.
