Filter by:Investigators developed an online educational module (ESTIMATE) to teach Gastroenterology (GI) trainees how to estimate polyp size using a snare. Key components include video instruction and real-time feedback incorporated over a 40-item polyp size assessment test. Trainees from GI fellowship programs will be randomized to one of four groups: control (no video, no feedback), video-only, feedback-only, and video + feedback. Participants will classify polyps into one of three size categories:- diminutive (1-5 mm), small (6-9 mm), and large (≥10 mm). Primary outcome is accuracy of polyp size classification [diminutive (1-5 mm), small (6-9 mm), and large (≥10 mm)]. Secondary outcomes include accuracy of exact polyp size (in mm), cumulative accuracy (to plot learning curves), confidence level of polyp size classification, and directionality of inaccuracy (polyp size overestimation vs underestimation).
It is estimated that about 20% of colonoscopies have inadequate preparation. (5) This is associated with lengthy procedures and less detection of adenomas, reduces the screening intervals, and increases the costs and risks of complications. Several strategies have been proposed to improve the quality of bowel preparation. Mobile healthcare Apps have been developed to increase adherence to bowel preparation agents, improving the quality of bowel preparation. However, adherence to mobile healthcare Apps is also a quality criterion and a pending problem to solve with this new technology. GastroBot is a new technology based on artificial intelligence that allows, through a software bot, to carry out a personalized follow-up of the patient's bowel cleansing, advising the patient to overcome contingencies that arise with the preparation, which in other circumstances could lead to the failure of it. The primary aim of this study is to determine the improvement in bowel preparation after GastroBot assistance compared with the traditional explanation. As a secondary aim, this study also pursues to determine adenoma and polyp detection rates (ADR and PDR, respectively), bowel preparation agents' tolerance, and GastroBot functionality.
The aim of this study is to evaluate the safety and efficacy of neoadjuvant immunotherapy combined with chemotherapy before colonic resection in patients with locally advanced colon cancers
The goal of this observational study is to determine whether the secreted protein QSOX1 can be used as a molecular marker for early rapid diagnosis and accurate treatment of colon cancer.
OBJECTIVE: To evaluate the effectiveness of a PET scan in oncological patients, with and without simultaneous treatment with chemotherapy, radiotherapy or hormonal therapy, in improving quality of life and the need for supervision by health professionals during its performance after 6 weeks of intervention. DESIGN: Randomized controlled clinical trial, parallel groups with active control group. With randomization blinding, patient assessment and data analysis. STUDY SUBJECTS: 78 patients diagnosed with breast and colon cancer and treated up to 2 years later, both with surgery, chemotherapy and hormonal treatments (aromatase inhibitors, tamoxifen). INTERVENTION: three treatment groups: supervised therapeutic exercise group without supervised therapeutic exercise group without chemotherapy, radiotherapy or hormonal treatment, supervised therapeutic exercise group with simultaneous chemotherapy, radiotherapy or hormonal treatment and control group. Two groups will be supervised in performing PET for a period of 6 weeks and the other group will do it autonomously and unsupervised. Patients will be followed for 1 year, with five blinded assessments: at baseline, after 6 weeks of intervention, 3, 6 and 12 months after baseline. MEASUREMENTS: Main: Quality of life assessed with questionnaire measured with the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire C-30 (EORTC QLQ-30). Measured pre-post intervention, 3, 6 and 12 months. Secondary: Cancer-related fatigue assessed with the Functional Assessment of scale Chronic Illness Therapy - Fatigue (FACIT-F). Measured pre-post intervention, 3, 6 and 12 months. Functional capacity measured with the 6-minute walk test. Pre-post intervention measurement, 3, 6 and 12 months. Strength assessment measured with manual hydraulic dynamometer and 5 repetitions of the sit-to-stand test. Pre-post intervention measurement, 3, 6 and 12 months.
We will conduct a multicenter, parallel-group, non-inferiority RCT in persons with IBD undergoing colorectal neoplasia screening with high-definition white light colonoscopy, comparing a strategy of sampling visible lesions alone to a conventional strategy of sampling both visible lesions as well as normal-appearing mucosa using non-targeted biopsies. The primary outcome is the neoplasia detection rate. The required sample size to demonstrate non-inferiority is 1952 persons.
CROSCO-1 study is a national, multi-center, prospective observational study presenting patients to the emergency departments of the participating centers with obstructive left colon cancer (in the absence of metastases and peritoneal carcinomatosis) undergoing primary surgical tumor resection with a primary colorectal anastomosis (associated or not with a diverting loop ileostomy) or without a primary anastomosis ("Hartmann's procedure") or staged resection after endoscopic stenting with Self-expandable Metallic Stent (SEMS). The main questions it aims to answer are: - the Stoma rate at 1 year after tumor resection - the 30-day and 90-day major morbidity and mortality - 1-year quality of life (EQ-5D-5L test) - Timing of chemotherapy initiation and type of chemotherapy regimen. Participants will have an obstructive left colon cancer localized (no peritoneal carcinosis or distant metastasis). Researchers will compare: primary surgical tumor resection with a primary colorectal anastomosis (associated or not with a diverting loop ileostomy) or an "Hartmann's procedure" with a staged resection after endoscopic stenting with SEMS.
The goal of this clinical trial is to evaluate the diagnostic potential of Artificial Intelligence-assisted Fecal Microbiome Testing for the diagnosis of colon cancer. The main question it aims to answer is: • Is Artificial Intelligence-assisted Fecal Microbiome Testing a reliable screening test for colon cancer? Participants will be asked to provide fecal samples to be analyzed with next-generation sequencing techniques. If there is a comparison group: Researchers will compare the diagnostic performance of AI-assisted Fecal Microbiome Testing with colonoscopy to see the correlation between the results of both interventions.
The goal of this clinical trial is to quantify the effects of aerobic exercise training compared to attention control on intermuscular adipose tissue in colorectal cancer survivors.
To goal of this clinical trial is to quantify the dose-response effects of aerobic exercise training compared to attention control on chemotherapy relative dose intensity in colon cancer survivors.
