The relative risk of colorectal cancer (CRC) is increased in first-degree relatives of patients with CRC or advanced adenoma. In the high-risk CCR population defined by a family history at the first stage of CRC or advanced adenoma before age 60, total colonoscopy is the recommended screening test. In France, the rate of screening colonoscopy in this population at high risk of CRC is insufficient, which limits the effectiveness of this targeted screening. The main reason for this low participation rate is that most patients undergoing RCC or advanced adenoma are unaware of the family implications of their diagnosis and therefore reluctant to disseminate this information to their patients Related matters. The need for a better perception of the personal risk of CRC in first-degree relatives of patients with CRC or advanced adenoma, with the expected coronary adherence to increasing screening, requires a good understanding of risk through Clear, adapted and comprehensible information that can be relayed personally by the case-index. The objective of this project is to develop a personalized prevention and screening program for the JRC in order to meet the needs of the relatives of the sick. The means of intervention that will be implemented respond to the need to better take into account the level of CRC risk in a family-based CRC screening and prevention approach adapted to a high-risk CRC group characterized by Family history at the first stage of CRC or advanced adenoma and, consequently, to improve the information of the subjects concerned by screening and prevention of CRC. The aim of the case-index education is to induce its intervention with its relatives to promote CCR screening. The use of the index case, as a means of providing information to relatives, implies an educational and psychological approach, based on evidence, but adapted and personalized.
This study aims to assess the effect, if any, on the adenoma detection rate of BowelScope bowel cancer screening flexible sigmoidoscopies by using the Endocuff Vision device.
Colorectal cancer (CRC) is the most common tumor and the second leading cause of death in the Western world. The decrease in incidence and mortality by CRC in the population undergoing screening has been observed. Colonoscopy is the recommended method for detecting tumors in early stages, as well as identifying and resecting adenomatous polyps, which are the precursor lesions of most CRCs. Colonoscopy should be of high quality to decrease incidence and mortality by CRC and avoid interval cancer. The literature shows that colonoscopy does not prevent right colon lesions in the same way as the left colon lesions, with most of the interval cancers located in the right colon. Studies published so far show an increase in the adenomas detection rate (ADT) in the right colon in the second visualization of this segment and an increase between 2 and 10% if this second examination is performed with the proximal retroflexion maneuver.Retroflexion is a safe maneuver in expert endoscopists. The aim of our study is to evaluate the ADT in the right colon by means of a second visualization by performing proximal retroflexion or second frontal visualization at random in the CCR screening population.
The only known cure for primary hyperparathyroidism is surgical removal of one or more parathyroid glands. Some patients however, do not fulfill criteria for surgery or do not want to undergo a procedure due to fear of the associated risks. Therefore a medical alternative is warranted. This study aims to evaluate the effects of Denosumab alone, and in combination with Cinacalcet, as a medical treatment for patients suffering from primary hyperparathyroidism, with mild osteoporosis. To the best of our knowledge no previously reported randomized controlled trial has investigated the use of denosumab in primary hyperparathyroidism. 60 patients will be enrolled in three different treatment-groups: 20 receiving both Denosumab and Cinacalcet, 20 Denosumab and placebo and 20 placebo and placebo. Patients included do not meet the criteria for, or have no wish for a surgical procedure. By combining the two drugs, this study could possibly contribute to the discovery of a realistic medical alternative to surgery. It is expected that the therapy will be able to both control s-calcium and s-intact parathyroid hormone (iPTH), and simultaneously enhance bone-structure. The therapy thus has the potential of preventing fractures and possibly other long-term effects of primary hyperparathyroidism such as formation of kidney stones, and coronary calcification. Another objective of this project is to investigate whether the combined therapy can facilitate an actual reset of the Calcium-sensing receptor, and thereby de facto cure the disease.
Randomized, comparative and prospective study between Conventional Endoscopic Mucosal Resection for the removal of flat or sessile colorectal lesions without previous attempt to resection.
This clinical trial studies the omission of intact parathyroid hormone testing during surgery in treating patients with primary hyperparathyroidism. Omission of intact parathyroid hormone testing during parathyroid gland removal may help patients with primary hyperparathyroidism to decrease their time under anesthesia, and decrease the overall time and cost of surgery.
The aim of this study is to assess the feasibility and the safety of the Novel Motorized Spiral Endoscope to examine the colon. The study is conceived as proof of concept trial with the primary aim to achieve a cecal intubation rate of at least 90 % according to quality guidelines recommendations. All other clinically relevant quality parameters of standard colonoscopy will be evaluated as secondary aims comparable to our recent trial. This study represents the first clinical evaluation of using a motorized spiral assisted endoscope for examination of the colon with potential advantages for patients in terms of effectiveness and convenience of 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 evaluation of the several hidden areas of the colon. The FUSE, full spectrum endoscopy system, has been demonstrated to reduce the rate of missed lesions due to its wide-angle view. In the present study the authors evaluate the impact of WT on ADR for High Definition Standard Endoscopes with just a single imager to the FUSE endoscope.
Recently a low-volume polyethylene glycol containing ascorbic acid (PEG-Asc) formulation has proven as safe and effective as traditional 4-L PEG solutions for colonoscopy preparation. However, currently available aqueous purgative formulations are poorly tolerated. The aim of this study was to compare a split-dose 2-L PEG-Asc and a 1-L PEG-Asc with bisacodyl (10 mg) formulation to determine the quality of bowel cleansing and patient tolerability.
