Filter by:The purpose of this study is to assess whether the use of large screen during colonoscopy will increase adenoma detection rate.
Volatile organic compounds (VOCs) are low molecular weight (<1 kDa) compounds which represent the final products of cell metabolism. Their composition can be affected by several factors including diet, hormones, environment and the presence of diseases, in particular, cancer. Colorectal cancer (CRC) is one of the commonest tumours and is an important cause of cancer-related mortality. The expression of VOCs in breath that are linked to a patient's disease state could offers a powerful, non-invasive approach to identifying CRC patients.
Comparison of the number of adenomas missed by the first exploration of the right colon by LCI (linked color imaging) or by white light during a colonoscopy, according to the order of randomization.
A multi-center randomized controlled trial in only 24 patients showed a significant reduction of the recurrence rate by treatment of the normal appearing perimeter of the EMR defect using the argon plasma coagulator (2). A recent non-randomized trial suggested a substantial reduction by treatment of the perimeter with the snare tip in the soft coagulation mode (3).
The study shall mainly help to better evaluate the performance the APDS device and secondly it may help to assess the potential of the future alpha version of the device to be a useful and effective for the detection of colon Polyps.
Endoscopic full-thickness resection (EFTR) in the colon using an over-the-scope clip (OTSC) as a closure mechanism is a recent technique that allows the endoscopic resection of colonic lesions that are poor candidates for conventional endoscopic resection techniques. The aim is to study the safety and efficacy of EFTR in colon.
The Italian Society of Digestive Endoscopy (SIED) and the Italian Association of Gastroenterologists and Hospital Digestive Endoscopists (AIGO) want to develop an effective training program for endoscopists to improve the quality of colonoscopies through careful evaluation of quality indicators and how they can be improved with an appropriate educational program. Primary objective of this study is to evaluate the variation of "Polyp Detection Rate (PDR) and Adenoma Detection Rate (ADR)" obtained by operators at high and low volume of colonoscopy before and after a training period. Secondary objectives are to compare high and low volume endoscopists' performance before and after training comparing by evaluation of withdrawal time; Number polyps / patient and Number adenomas / patient; the percentage and time of intubation of the cecum, ; patient's pain perception based on the Nurse Assessed Patient Comfort Score (NAPCOMS) scale. The study is structured as follow: - A first phase when all endoscopists collect the results of 200 colonoscopies in an electronic Case Report Form (eCRF) is formed(maximum enrollment period 4 months). - A second phase of training through an e-platform in which the endoscopists are offered with an online refresh reviewing the international standard parameters to perform a quality colonoscopy. Once the final training exam have been passed, the endoscopist will be able to access the third phase - A third phase in which the endoscopists will collect prospectively the colonoscopies they perform in an eCRF (maximum enrollment period 4 months).
A prospective, multicentre, observational study of all patients referred for endoscopic resection of sessile colorectal polyps sized ≥20 mm conducted with intention to treat analysis
An NBI-based diagnosis requires training and experience. We are developing a system of computerized image recognition, which can detect possible NBI features of polyps, and provide a more objective diagnosis, which allows nonexpert endoscopists to achieve a high diagnostic accuracy.
This is a retrospective and prospective multicenter registry to collect long-term data (1 year) on patients who have or will undergo Endoscopic resection such as EMR, ESD, EFTR, STER, etc. within the gastrointestinal tract for endoscopic treatment of early gastrointestinal neoplasms involving the resection of the superficial layers, mucosa and submucosa, of the tract wall. Subjects will be consented for medical chart review. The purpose of this retrospective and prospective registry is to assess long term data on efficacy, safety and clinical outcome of Endoscopic Resection within the gastrointestinal tract (1 year). The registry will evaluate efficacy, technical feasibility, clinical outcome, safety profile and overall clinical management through medical chart review. The procedures the investigators are evaluating are all clinically indicated and will not be prescribed to someone to participate in this registry study.
