NCT ID: NCT06180798 Recruiting - Polyps Clinical Trials

Cold Snare Endoscopic Mucosal Resection (C-EMR) Versus Hot Snare Endoscopic Mucosal Resection (H-EMR) for Large Colorectal Polyps (10-20 mm)

Start date: January 10, 2024
Phase: N/A
Study type: Interventional

OBJECTIVES The aim of the study is to compare the efficacy of cold snare EMR versus hot snare EMR for non-pedunculated polyps 10-20mm in size with respect to complete resection rates and adverse events. DESIGN : A Randomised interventional study. Sample size: 330

NCT ID: NCT05121805 Recruiting - Polyps of Colon Clinical Trials

Recurrences After Standard EMR vs Plus Thermal Ablation EMR

RESPECT
Start date: March 17, 2022
Phase: N/A
Study type: Interventional

The primary objective of this trial is to investigate whether thermal ablation EMR with soft tip snare coagulation (STSC) reduces the recurrence rate of lateral spreading or sessile polyps ≥20mm compared to standard EMR.

NCT ID: NCT05064124 Not yet recruiting - Colorectal Polyp Clinical Trials

Early diAgnosis Real-Time Healthcare System for CANcer Trial

EARTHSCAN
Start date: June 2024
Phase:
Study type: Observational

The purpose of the study is to assess whether the AI characterisation system of the CADDIE device improves the endoscopists accuracy in the optical diagnosis of diminutive colorectal polyps in the bowel during colonoscopy. Participants will either have a colonoscopy with the assistance of the CADDIE device characterisation AI system ("intervention group") or have a colonoscopy in line with routine clinical practice i.e., without the CADDIE device characterisation AI system ("control group"). The randomisation method of this trial will allocate enrolled participants to the "intervention" group and to the "control" group by a technique similar to flipping a coin.

NCT ID: NCT05006092 Completed - Clinical trials for Artificial Intelligence

Surveillance Modified by Artificial Intelligence in Endoscopy (SMARTIE)

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

Evaluation of an artificial intelligence system for polyp detection (CADe)

NCT ID: NCT04657601 Not yet recruiting - Polyps of Colon Clinical Trials

Prospective Study of a New Endolumenal Device Used During Endoscopic Polypectomy in the Colon

DiLumenC2
Start date: January 15, 2021
Phase:
Study type: Observational

This prospective observational study will evaluate the performance of the DiLumen C2 Endolumenal Interventional Platform and its instruments. Up to 100 subjects will be enrolled at up to 5 clinical sites. Patient data will be collected before the procedure, during the procedure, and up until the patient is discharged from the hospital.

NCT ID: NCT04441580 Recruiting - Rectal Neoplasms Clinical Trials

Assessing the Additional Neoplasia Yield of Computer-aided Colonoscopy in a Screening Setting

GENIAL-CO
Start date: May 4, 2020
Phase: N/A
Study type: Interventional

Even if colonoscopy is considered the reference standard for the detection of colonic neoplasia, polyps are still missed. The risk of early post-colonoscopy cancer appeared to be independently predicted by a relatively low polyp/adenoma detection rate. When considering the very high prevalence of advanced neoplasia in the FIT-positive enriched population, the risk of post-colonoscopy interval cancer due to a suboptimal quality of colonoscopy may be substantial. Available evidence justifies therefore the implementation of efforts aimed at improving adenoma detection rate, based on retraining interventions and on the adoption of innovative technologies, designed to enhance the accuracy of the endoscopic examination. Artificial intelligence seems to improve the quality of medical diagnosis and treatment. In the field of gastrointestinal endoscopy, two potential roles of AI in colonoscopy have been examined so far: automated polyp detection (CADe) and automated polyp histology characterization (CADx). CADe can minimize the probability of missing a polyp during colonoscopy, thereby improving the adenoma detection rate (ADR) and potentially decreasing the incidence of interval cancer. GI Genius is the AI software that will be used in the present trial and is intended to be used as an adjunct to colonic endoscopy procedures to help endoscopists to detect in real time mucosal lesions (such as polyps and adenomas, including those with flat (non-polypoid) morphology) during standard screening and surveillance endoscopic mucosal evaluations. It is not intended to replace histopathological sampling as a means of diagnosis. The objective of this study was to compare the diagnostic yield obtained by using CADe colonoscopy to the yield obtained by the standard colonoscopy (SC).

NCT ID: NCT03515343 Completed - Colo-rectal Cancer Clinical Trials

Optivista : I-SCAN OE for Optical Diagnosis of Small Colon Polyps

Optivista
Start date: March 9, 2018
Phase:
Study type: Observational

This prospective randomized clinical trial aims to evaluate the new Optivista system compared to the iScan for his optical diagnosis and interval agreement monitoring with pathology. The Participants will be randomized to be diagnosed by either Optivista or Pentax iScan, and all polyps detected during the procedure, their size, location and morphology will be recorded according to the Paris classification after which all polyps will be resected per standard practices and sent for histopathologic evaluation. Further optical assessments will be performed for all polyps of 1-10 mm in size (WASP, NICE, SANO and SIMPLE classification) after with an analysis of comparison between optical diagnosis and pathology results will be performed.

NCT ID: NCT03467451 Completed - Polyps of Colon Clinical Trials

Rétrospective Evaluation of the Performance and the Safety of the Endoscopic Mucosectomy With Anchorage

Start date: July 1, 2015
Phase:
Study type: Observational

This safe and simple technique without extra cost would allow us to improve R0 resection ratio and so decrease relapses and the time between two different exams

NCT ID: NCT03448653 Terminated - Polyps of Colon Clinical Trials

Contribution of Narrow Band Imaging (NBI) for the Characterization of Scalloped Polyps (NBI POLYPES COLIQUES)

Start date: July 9, 2018
Phase: N/A
Study type: Interventional

This prospective bicentric trial aims to evaluate the diagnostic performance of the characterization of scalloped polyps less than 20 millimeter in NBI (Narrow Band Imaging) in patients with screening colonoscopy. The NBI is a so-called "virtual" electronic staining technique available on conventional OLYMPUS endoscopes without additional intervention. The colonoscopy procedure for each patient will not be different from a conventional colonoscopy examination with excision of all polyps visualized and anatomopathological analysis, except for a short time of analysis in NBI for each polyp detected before excision to classify the polyp in existing endoscopic classifications (ie NICE classification for adenomatous polyps and WASP classification for festooned polyps).

NCT ID: NCT03346005 Completed - Colorectal Cancer Clinical Trials

Detection of Colorectal Cancer in Patients With a Positive Fecal Immunochemical Test Using an Electronic Nose Device (AeoNoseTM)

Start date: November 9, 2017
Phase: N/A
Study type: Interventional

The present study aims to investigate the diagnostic accuracy of exhaled breath analysis with the Aeonose (the eNose Company, Zutphen, the Netherlands) to distinguish the breath of patients suspected for CRC (based on a positive fecal immunochemical test), who are truly diagnosed with CRC, from patients suspected for CRC in whom this diagnosis is rejected after colonoscopy.
