NCT ID: NCT03712059 Completed - Colorectal Polyp Clinical Trials

National Colorectal Polyp Care

NCPC
Start date: November 1, 2018
Phase:
Study type: Observational

This study has three main purposes:screening: the first purpose is to evaluate the diagnostic value of combintion of the life risk factors and immunochemical fecal occult blood test (FIT) on detection of colorectal neoplasia in Chinese population; resection: the second objective is to investigate the complete resection rate of colorectal adenoma and risk factors of incomplete resection in China; identification and classification: the third objective is to initially establish an artificial intelegence-assissted recognition and classification system of polyp based on deep learning.

NCT ID: NCT03155308 Completed - Colorectal Polyp Clinical Trials

Validation of the NICE Classification Using Pentax Chromoendoscopy

Start date: April 1, 2017
Phase:
Study type: Observational

Colorectal cancer (CRC) is the most frequent gastrointestinal tumor and the second cause of cancer related death. Colonoscopy is currently the recommended method for detection of polyps and cancers in the colon. Removal of all adenomatous polyps during colonoscopy has become worldwide a standard procedure as it has been demonstrated to significantly reduce colorectal cancer incidence and mortality. It is routine practice to remove all the detected polyps for pathological evaluation, due to the low accuracy (59% to 84%) to differentiate non-neoplastic from neoplastic colorectal lesions with white-light endoscopy. The development of electronic or virtual chromoendoscopy (CE) has aimed to reliably predict histology of colorectal lesions based on endoscopic features. This technology differentiates between neoplastic and non-neoplastic lesions base on the analysis of the neo-angiogenesis and the mucosal pit pattern. Optical endoscopic diagnosis allows the real-time evaluation of polyp histology during colonoscopy and to determine the appropriate therapeutic strategy. This is important in clinical practice, since adenomas or superficial invasive submucosal carcinoma lesions can be curatively treated by endoscopic removal, unlike deeply invasive carcinomas, which requires surgery. The Narrow-band imaging (NBI) international colorectal endoscopic (NICE) classification is validated classification system proposed as a valid tool for not only differentiating hyperplastic from adenomatous polyps, but also predicting submucosal deep (SM-d) carcinomas. It was developed based on NBI technology, leaving uncertainty on its applicability to other systems. It was previously evaluated the application of the NICE classification to Fujinon spectral Imaging Color Enhancement (FICE) technology founding suboptimal results (accuracy 77%, sensitivity 77% and specificity 75%) and moderate inter-observer agreement (kappa: 0.51).

NCT ID: NCT03118856 Completed - Colorectal Polyp Clinical Trials

Electronic Chromoendoscopy for Polyp Characterization

Start date: February 1, 2017

NCT ID: NCT02963207 Completed - Clinical trials for Colorectal Neoplasms

MS Versus NICE for Colorectal Lesions

Start date: June 2013
Phase: N/A
Study type: Interventional

OBJECTIVE: Our study aimed to compare a recently-developed endoscopic classification with an established one for colorectal lesions in a randomised trial between 2013 and 2015.

NCT ID: NCT01800656 Completed - Colorectal Polyp Clinical Trials

Assessing Endoloop-assisted Polypectomy in Patients With Antiplatelet Therapy

Start date: January 2004
Phase: N/A
Study type: Interventional

The aims of this study were to examine: 1) safety and feasibility of antiplatelet therapy interruption 7 days prior to polypectomy in patients with long-term antiplatelet therapy; 2) safety and feasibility of endoloop assisted snare polypectomy in patients with long-term antiplatelet therapy; 3) safety and feasibility of so called "ligate and let go" approach in patients with long-term antiplatelet therapy.
