Filter by:The study will compare the use of cold snare piecemeal resection (CSPR) vs cold endoscopic mucosal resection (Cold EMR). The study will include two cohorts: one cohort for conventional adenomas 10-19mm in size and one cohort for serrated lesions 10mm or larger.
In recent years, computer-aided diagnosis system based on artificial intelligence (AI) has been used in colorectal polyp detection. In recent years, computer-aided diagnosis system based on artificial intelligence (AI) has been used in colorectal polyp detection. However, whether AI-assisted can improve the adenoma-detection rate (ADR) is inconclusive. This study aims to evaluate the real-world performance of an AI system that combines polyp detection with colonoscopy quality control. This study aims to explore the clinical application value of AI-based polyp detection and quality control function by comparing the data of polyp detection rate and adenoma detection rate in multiple centers with and without AI-assisted colonoscopy in a multicenter, prospective real world study.

The goal of this study is determine the safety and tolerability of orally taken probiotic (R-5780) in patients currently on a PD-1 Pathway Checkpoint Inhibitor (checkpoint protein on immune cells called T cells) with Solid Tumors.
The goal of this observational study is to evaluate, retrospectively and prospectively, the effect of different hormonal and neuropeptide dysfunctions on the body composition of patients suffering from hypothalamic-pituitary pathologies, and to evaluate the potential beneficial effect of surgical and medical treatments with agonists and antagonists of hypothalamic neuropeptides, currently available, on the development and treatment of adiposity and negative cross-talk between adiposity and muscle/bone tissue
Colorectal tubular adenoma is the most common precancerous lesion of colorectal cancer, and the point is that its precise prevention and treatment can reduce the incidence of colorectal cancer.However, the epidemiological characteristics of colorectal tubular adenoma in China are unclear, the rate of missed diagnosis by colonoscopy is high, and the existing diagnosis and treatment techniques are lack of unified quality control standards,which makes it difficult to diagnose and achieve accurate prevention and control. How to improve the precise prevention and treatment of colorectal tubular adenoma and reduce the incidence of colorectal cancer is a major clinical scientific problem that needs to be solved urgently. For this purpose, this study was conducted in colorectal guided by the needs of accurate prevention and treatment of tubular adenoma lesions,and a multi-center colorectal tubular adenoma data management platform and a high-risk population database covering a full range of data including demographic characteristics, lifestyle factors, clinical information, endoscopic data and pathological images were established, biological sample databases of patients with pathological changes and high-risk populations were established, and data quality control and sample quality control standards were formulated standards-based. The pathological prediction model and accurate risk assessment system of colorectal tubular adenoma were constructed by the pathological database.
CoLiQ is an observational study designed to evaluate the clinical usefulness of circulating tumor DNA (ctDNA) markers found in blood, as a liquid biopsy for diagnosis, prognosis and follow-up of colorectal cancer. The main questions it aims to answer are: 1) Can a panel of ctDNA markers identify CRC patients among the other patients summoned for colonoscopy? and 2) Does the type, number and level of ctDNA markers vary with the subtype and clinical course of CRC? Participants will be asked to answer a questionnaire and give a blood sample at inclusion. In addition, patients with CRC will be asked to give an extra test tube at their routine treatment and follow-up blood sampling.
The primary purpose of this study is to compare the safety of routine telephone assessment versus in-person assessment during a two-year period for patients with non-functioning pituitary adenomas. Secondly, to compare the quality of pituitary care in persons having biochemical assessment once versus twice a year. Thirdly, to assess the rationale of repeated assessment of pituitary function and imaging in patients with small pituitary tumors (microadenomas).
The primary objective is to determine the diagnostic sensitivity and specificity of the newly developed liquid biopsy based multiomics Colorectal Cancer (CRC) screening test (CRC-Appareo) for detecting advanced neoplasia (including colorectal cancer and advanced adenomas) in high risk patients and patients with confirmed CRC, using colonoscopy as the reference method. The secondary objective is to compare the screening performance of the multiomics Colorectal Cancer (CRC) screening test with commercially available FIT (Fecal Immunochemical Test) assay in detecting advanced neoplasia.
This randomized, multi-center trial aims to evaluate the advantages of underwater cold endoscopic mucosal resection technique (CS-EMR) in comparison to the conventional endoscopic mucosal resection technique (EMR) for laterally spreading colorectal lesions exceeding 20 mm in size. More precisely, our hypothesis posits that underwater cold EMR is non-inferior to conventional EMR in terms of recurrence rates, resection completeness and safety.
Recurrence after endoscopic papillectomy is described in up to 33% of the cases (range 12-33%). This leads to re-interventions, a cumulative risk of adverse events, and the need for long-term follow-up. Recurrences most likely originate from either the biliary orifice or lateral resection margins. Ablative methods such as radiofrequency ablation (RFA) and thermal ablation by cystotome inside the bile duct have been described to treat intraductal extension of which the use of a cystotome seems to have a more favorable safety profile. However, no studies focusing on the preventive use of these ablative methods in patient with papillary adenomas have been performed.
