Inspection of the Colon Using a Retrograde Viewing Device for Detection of Colorectal Polyps

2019-10-03 07:54:48 | BioPortfolio


During standard colonoscopy a substantial number of colorectal polyps may be missed. Previous studies have found a 12-28% of miss rate for all polyps, a 31% for hyperplastic polyps and 6-27% for adenomas. In this study it is tested whether a retro viewing endoscope can detect more colorectal polyps in comparisson to standard forward viewing endoscopy. Further, ppolyps detected, mean adenomas per Patient and withdrawal time are recorded.

The Same-day bidirectional endoscopy (BDE) is commonly used in clinical practice. However, the optimal sequence of performing a same-day BDE has not been well-established.The primary aims ...

Withdrawal Time and Use of Wide-angle Endoscope to Increase the Adenoma Detection Rate of Screening Colonoscopy

Colonoscopy outcome is strictly related to the adenoma detection rate (ADR). An endoscopy withdrawal time >6min has been suggested to increase the ADR since it allows for thorough evaluati...

Endocytoscopy for the differential diagnosis of colorectal low-grade adenoma: a novel possibility for the "resect and discard" strategy.

Endocytoscopy, a next-generation endoscopic system, facilitates observation at a maximum magnification of ×520. To our knowledge, no study has reported high-precision diagnosis of colorectal low-grad...

Magnetic Resonance Imaging and Histopathology in a Case of Pleomorphic Adenoma of a Minor Salivary Gland in the Nasal Cavity.

Medical and Biotech [MESH] Definitions

Procedures of applying ENDOSCOPES for disease diagnosis and treatment. Endoscopy involves passing an optical instrument along either natural body pathways such as the digestive tract, or through keyhole incisions to examine the interior parts of the body. With advances in imaging, endoscope, and miniaturization of endosurgical equipment, surgery can be performed during endoscopy.

A pituitary adenoma which secretes ADRENOCORTICOTROPIN, leading to CUSHING DISEASE.

Visualization of the heart structure and cardiac blood flow for diagnostic evaluation or to guide cardiac procedures via techniques including ENDOSCOPY (cardiac endoscopy, sometimes refered to as cardioscopy), RADIONUCLIDE IMAGING; MAGNETIC RESONANCE IMAGING; TOMOGRAPHY; or ULTRASONOGRAPHY.

An adenoma of the large intestine. It is usually a solitary, sessile, often large, tumor of colonic mucosa composed of mucinous epithelium covering delicate vascular projections. Hypersecretion and malignant changes occur frequently. (Stedman, 25th ed)

Neoplasms which arise from or metastasize to the PITUITARY GLAND. The majority of pituitary neoplasms are adenomas, which are divided into non-secreting and secreting forms. Hormone producing forms are further classified by the type of hormone they secrete. Pituitary adenomas may also be characterized by their staining properties (see ADENOMA, BASOPHIL; ADENOMA, ACIDOPHIL; and ADENOMA, CHROMOPHOBE). Pituitary tumors may compress adjacent structures, including the HYPOTHALAMUS, several CRANIAL NERVES, and the OPTIC CHIASM. Chiasmal compression may result in bitemporal HEMIANOPSIA.
