NCT ID: NCT06173297 Completed - Colorectal Cancer Clinical Trials

Assessing the Agreement Between Endoscopic and Histopathological Diagnosis of Colorectal Sessile Serrated Lesions.

Start date: February 1, 2020
Phase:
Study type: Observational

The goal of this observational study was to assess the degree of agreement between the endoscopic and anatomopathological diagnosis of sessile serrated colorectal lesions in adult patients undergoing colonoscopy in Hospital Sírio-Libanes. The main questions it aimed to answer were: - The degree of agreement between endoscopic and anatomopathological diagnosis of sessile serrated colorectal lesions by calculating the Kappa Value of agreement. - To establish the detection rate of sessile serrated lesions and adenomas in the Endoscopy Department at Hospital Sírio-Libanês. - To evaluate the degree of agreement between endoscopic and anatomopathological diagnosis of sessile serrated colorectal lesions based on the resection method. - To assess the accuracy, positive predictive value, and negative predictive value of endoscopic diagnosis of serrated lesions compared to anatomopathological diagnosis. The data were prospectively collected through a form specifically designed for this project, that was completed immediately after the examination by the performing colonoscopist. All patients enrolled in this study agreed to participate in it and signed an informed consent form prior to the colonoscopy.

NCT ID: NCT05089071 Completed - Colonoscopy Clinical Trials

Effect of Two Colonoscopy AI Systems for Colon Polyp Detection

Start date: November 1, 2021
Phase: N/A
Study type: Interventional

Computer-aided detection (CADe) systems have been actively researched for polyp detection in colonoscopy. The investigators aim to identify the effect of two CADe systems according to the system performance on false positive rate

NCT ID: NCT04723758 Completed - Colorectal Adenoma Clinical Trials

COLO-DETECT: Can an Artificial Intelligence Device Increase Detection of Polyps During Colonoscopy?

Start date: March 29, 2021
Phase: N/A
Study type: Interventional

COLO-DETECT is a clinical trial to evaluate whether an Artificial Intelligence device ("GI Genius", manufactured by Medtronic) can identify more polyps (pre-cancerous growths of the bowel lining) during colonoscopy (large bowel camera test) than during colonoscopy without it.

NCT ID: NCT03560037 Completed - Clinical trials for Sessile Serrated Adenoma

Use of a Distal Colonoscope Attachment to Increase Detection of Sessile Serrated Adenomas

Start date: May 1, 2019
Phase: N/A
Study type: Interventional

This study evaluates whether the use of a disposable colonoscope attachment, Endocuff Vision, can increase the detection of sessile serrated adenomas. Participating patients will be randomized to receive either standard colonoscopy or colonoscopy with the Endocuff Vision.

NCT ID: NCT03297996 Completed - Colorectal Cancer Clinical Trials

Study of Gut Microbiome and Colorectal Tumors

Start date: November 23, 2011
Phase: N/A
Study type: Observational

Gut microbiota were assessed in 540 colonoscopy-screened adults by 16S rRNA gene sequencing of stool samples. Investigators compared gut microbiota diversity, overall composition, and normalized taxon abundance among these groups.

NCT ID: NCT03100552 Completed - Clinical trials for Sessile Serrated Adenoma

Prediction of Dysplasia Within Sessile Serrated Polyps Using Endoscopic Imaging; a Prospective Observational Study

SERRESH
Start date: August 1, 2013
Phase:
Study type: Observational

Study of endoscopic imaging in the detection of dysplasia within serrated colonic lesions >= 8mm in size

NCT ID: NCT02406547 Completed - Clinical trials for Colorectal Neoplasms

Study of Narrow Band Imaging in the Characterization of Serrated Lesions

CROMOSER
Start date: March 2015
Phase: N/A
Study type: Interventional

This study is designed to evaluate the utility of Narrow Band Imaging (NBI) compared with High Definition White Light colonoscopy (WLE) in subjects with serrated lesions who do not fulfill the diagnostic criteria of Serrated Polyposis Syndrome (SPS).
