Filter by:The mains complications in colo-rectal dissection are the pain, the delayed bleeding and the perforation and represent around 10%. Currently, the procedure is realized during a hospitalization with not real recommendation about the time of this. There is currently no score established for the colo-rectal endoscopic submucosal dissection. - To develop clinical or mixed prognostic score after endoscopic subcostal dissection for colorectal lesions in Nancy's hospital. - Allow to obtain an estimation of number of patients required for a larger study.
Introduction It has been shown that some quality indicators in endoscopy can be improved through educational interventions. There are marked differences in the proportion of incomplete polypectomies among endoscopists. The effectiveness of measures to improve it has not been evaluated. Objective The main objective is to evaluate whether a training intervention or the notification of the individual proportion of incomplete polypectomies (those in which post-polypectomy biopsies of the resection margin show tissue other than normal mucosa) can improve this proportion. As secondary objectives, we will compare the proportion of fragmented polypectomies and adverse events. We will evaluate the factors associated with incomplete excision or failed cold polypectomy, as well as the individual evolution of the participants. Methods Non-pharmacological clinical trial involving endoscopists with> 1 year of experience and patients scheduled for colonoscopy. After each polypectomy, 2 additional biopsies will be taken and evaluated centrally by a blind pathologist. In a first phase, the basal rate of the participants will be evaluated. After it, the endoscopists will receive a course on endoscopic polypectomy and the other their rate of complete resection. The number of polyps required will vary depending on the number of endoscopists The primary objective will be compared using logistic regression models based on generalized estimating equations (GEE), taking into account the within-subject correlation.
Colonoscopy is an essential tool for diagnostic evaluation for a wide range of gastrointestinal complaints and is considered the gold standard for colorectal cancer screening. This procedure is often associated with patient anxiety both prior to and during the procedure, as well as discomfort,which is managed with procedural sedation.Anticipation of an uncomfortable experience can deter patients from undergoing the procedure despite it being medically indicated. Music has a number of beneficial effects including improving senses of relaxation and well being. Use of music during colonoscopy is inconsistent and there are no society guidelines or recommendations regarding its use. The investigators hypothesize that music will improve the overall patient experience and enhance endoscopist performance.The investigators propose a randomized controlled trial to study effects of music on both the patient experience and endoscopist performance during colonoscopy. Eligible patients will be randomized to two groups: a "music group" and a "no music"control group.Patients in the music group will be asked for their preference of music to be played during their colonoscopy. For patients in the music group, this music will be played in the procedure room during the procedure, while those in the control group will have no music playing. Patient anxiety and pain will be assessed both before and after the procedure.Overall patient experience after the procedure will be assessed on a likert scale. The performance of the endoscopist will be assessed by measuring adenoma detection rate and adenomas per colonoscopy. Additional outcomes to be assessed include total procedure time and amount of sedation required.
This study will evaluate the safety and effectiveness of the CapsoCam Colon (CV-3) endoscope system for the detection of colonic polyps.
EndoVigilant software device augments existing colonoscopy procedure video in real-time by highlighting colon polyps and mucosal abnormalities. It is intended to assist gastroenterologists in detection of adenomas and serrated polyps. The device is an adjunctive tool and is not intended to replace physicians' decision making related to detection, diagnosis or treatment. This study with an adaptive design measures the clinical benefit (increase in detection of adenomatous and serrated polyps) and increased risk (increased extraction of non-adenomas) during standard colonoscopy procedures when EndoVigilant software device is used.
The focus of the study is to evaluate impact of submucosal injection of EverLift in achieving complete resection during polypectomy of polyps 4-9mm during colonoscopy.
The focus of the study is to evaluate impact of cold forcep and cold snare in achieving complete resection during polypectomy of polyps <=3mm during colonoscopy.
Colorectal carcinoma (CRC) is the third most common cancer in male and female worldwide. In India, it is the fourth most common cause of cancer in males and third most common cancer in female. Age, smoking, colonic adenomatous polyp, family history are traditional risk factor for CRC. The vast majority of CRC results from malignant transformation from adenoma, which is called as adenoma carcinoma sequence. These adenomatous polyps grows slowly over many years and malignant transformation eventually occurs over 10 years. So, the early detection and removal of polyp at early stage should benefit in preventing CRC.
The purpose of this study is to assess whether computer aided technology (CAD) can help in the diagnosis of polyps found the bowel compared with visual inspection alone and therefore whether it is beneficial in helping clinicians to decide whether to remove a polyp or not. Presently, most endoscopists remove all polyps found and send them to the laboratory for testing. The number of colonoscopies is increasing, meaning that more polyps are detected and removed. This comes at a significant cost to the health service and increases the time taken to complete a colonoscopy.
Hypoxia is the most common adverse event during gastrointestinal endoscopes sedated with propofol and sufentanil, especially in obese people. In the present study, high-flow nasal cannula oxygenation will be utilized in order to reduce the incidence of hypoxia among obesity.
