Advanced Gastrointestinal Endoscopy Lab
Machine-translated · View original
A lab tackling gastrointestinal cancer through endoscopy research and device development.

AboutAbout the lab
Taking on gastrointestinal cancer with endoscopy
The Advanced Gastrointestinal Endoscopy Lab conducts cutting-edge research on endoscopy, focusing mainly on gastrointestinal cancer, and develops new endoscopic devices.
The lab was established at the Institute of Medical Science in October 2023.
Its work spans basic endoscopy research, clinical research, and the development of new devices that can be used in clinical practice.
The lab also conducts translational research with a variety of basic science labs within the institute, aiming to create new diagnostic and treatment methods.
Key terms
- Endoscope
- A medical device in which a thin tube is inserted through the mouth or anus, and a camera at its tip is used to look inside the body or perform treatment.
- Fecal occult blood
- Blood mixed into stool in amounts so small that it cannot be seen with the naked eye. It is a clue to conditions such as colorectal cancer.
- ESD
- Endoscopic submucosal dissection. A treatment in which cancer in the mucosa of the digestive tract is peeled away and removed with an endoscope from the layer beneath the mucosa.
ResearchResearch themes
Aiming to prevent gastrointestinal cancer, the lab works on research to detect and diagnose lesions, and on developing new medical devices that meet the needs of clinical practice. In 2025, it advanced the development of a device that measures fecal occult blood in the toilet, an artificial dermis that protects mucosal wounds, and a new hemostatic forceps.
*Illustrative imageMeasuring fecal occult blood in the toilet
The lab conducted a clinical trial to make it possible to measure fecal occult blood in the toilet. It aims to make the detection device smaller and to narrow down the optimal light wavelength for the measurement.
*Illustrative imageProtecting mucosal wounds with an artificial dermis
The lab tested a method of covering and protecting mucosal wounds after ESD with an artificial dermis, using porcine tissue and live pigs. It is a simple, low-cost method that may prevent bleeding and perforation after treatment.
