Filter by:Colonoscopy is the current standard method for evaluation of colonic disorders such as colorectal cancer, IBD, polyps, and other conditions.
The goal of the study is to determine, using a choice-based approach, what messages (pulled from various online sites) people find more and less persuasive and shareable on the topic of colorectal cancer screening. As a secondary goal, the study is interested how various information behaviors, such as people's self-reported seeking of health information and encountering of health information, demographic variables, individual difference variables, and message exposure associate with their intentions to adhere to recommended colorectal cancer screening guidelines from the National Cancer Institute. The study is interested at differences specifically among Black and White Americans of recommended screening age (45-74).
1. To establish the Chinese people's own clinical data database of colorectal cancer, reflecting the law and characteristics of colorectal cancer patients in China. 2. Based on colorectal cancer surgery, collect clinical data, especially data on clinical manifestations, complications, laboratory tests, auxiliary examinations, postoperative clinical effects, surgical complications, and colorectal cancer recurrence, so as to lead the direction of clinical practice and academic research of colorectal cancer surgery in China. It provides a certain basis for future research on colorectal cancer. 3. Provide academic consultation and data support to national health authorities.
The chemoprophylaxis of deep vein thrombosis (DVT) with subcutaneous low-molecular-weight heparin (enoxaparin) in the postoperative period of elective surgeries is already well established in the literature and in clinical practice. However, the use of this medication can have a financial impact on the patient and the parenteral presentation itself is associated with pain at the application site, which can make it difficult for patients to adhere.
Colonoscopy is considered the gold standard for diagnosis of colonic polyps. However, it was reported that colonoscopy could still miss colonic polyps. Many attempts have been made to improve the detection rate of colonoscopy. Artificial intelligence (AI) is a promising new technique to improve detection rate of colonic adenoma. However, it remains uncertain whether whether the combined use of Endocuff and AI assisted examination could help to further improve the adenoma detection rate. This is a prospective randomized trial comparing the use of endocuff with AI, AI alone or conventional colonoscopy examination on adenoma detection rate.
The aim of the study is to determine if Serrated Poliposis Syndrome (SPS) patients with SPS criteria 2, with clearing phase achieved and without any advanced lesion or less than 5 relevant lesions at last colonoscopy have the same advanced neoplasia incidence in the surveillance colonoscopy at 2 or 3 years. Patients selected for the study will be randomised in two groups for the surveillance: group 1, surveillance with colonoscopy in two years; group 2, surveillance with colonoscopy in three years. Randomization will be done at the database program (RedCAP). All colonoscopies will be performed with high definition (HD) system and it will be the choice of the endoscopist whether to use chromoendoscopy with indigo carmine o virtual chromoendoscopy. Protocol bowel preparation will be recommended by each centre. Sedation will be prescribed and decided by the endoscopist during the examination. Data from all the resected and visualized lesions during the colonoscopy will be collected on the database. A pathologist familiarized with serrated lesions will be in charge of the sample analysis. Serrated lesions will be classified attending de WHO criteria for serrated lesions. The investigators define "advanced adenoma" as adenomas ≥10 mm with villous histology and/or with high grade of dysplasia (HGD). The investigators define "advanced SL" as any SL ≥10mm and any SL with dysplasia. The investigators also define "advanced neoplasia" as any colorectal cancer (CRC), any advanced adenoma or advanced Serrated Lesions (SL). Quality of bowel cleansing will be graded by each endoscopist following the Boston Bowel Preparation Scale. This scale evaluates each segment (ascending colon, transverse colon and descending colon) of the following form: 0 = segment of colon whose mucosa cannot be seen due to the existence of solid stools that cannot be eliminated; 1 = mucosa portion of a colonic segment that can be seen, but other areas of the colonic segment are not seen, either due to the presence of dirt, feces or opaque liquid; 2 = existence of small amount of dirt, small fragments of stool and / or opaque liquid, but the mucosa of the colonic segment can be seen well; 3 = all the mucosa of the colonic segment can be seen well without residual dirt, small traces of stool or opaque liquid. Patients with inadequate preparation (when in any segment the score is 0 or 1, or the total score is less than 6) will be excluded from the study. During colonoscopy all complications as post-polypectomy bleeding, perforation or cardio-respiratory events will be registered. Those complications will be considered if surgery or hospital admission is required.
Liver metastases are present in 15-25% of patients with colorectal cancer at the time of diagnosis of the primary tumor, which is defined as synchronous liver metastases. Treatment for the potential cure of this disease includes surgical resection of both the primary tumor and liver metastases. The liver first approach was described by Mentha for patients with asymptomatic rectal tumors with with initially unresectable or borderline resectable liver metastases. There is little data in the scientific literature on how many patients scheduled for this strategy complete both surgeries and/or undergo the full chemo/radiation therapy.
The aim of this study is to demonstrate the feasibility, surgical, and oncologic outcomes of laparoscopic right hemicolectomy with CME and CVL compared to open surgery.
VAPOR-C is a randomised study of the impact of IV versus inhaled anaesthesia (propofol versus sevoflurane) and lidocaine versus no lidocaine on duration of disease free survival inpatients with either colorectal or non small cell lung cancer.
