Filter by:The goal of this observational study was to assess the degree of agreement between the endoscopic and anatomopathological diagnosis of sessile serrated colorectal lesions in adult patients undergoing colonoscopy in Hospital Sírio-Libanes. The main questions it aimed to answer were: - The degree of agreement between endoscopic and anatomopathological diagnosis of sessile serrated colorectal lesions by calculating the Kappa Value of agreement. - To establish the detection rate of sessile serrated lesions and adenomas in the Endoscopy Department at Hospital Sírio-Libanês. - To evaluate the degree of agreement between endoscopic and anatomopathological diagnosis of sessile serrated colorectal lesions based on the resection method. - To assess the accuracy, positive predictive value, and negative predictive value of endoscopic diagnosis of serrated lesions compared to anatomopathological diagnosis. The data were prospectively collected through a form specifically designed for this project, that was completed immediately after the examination by the performing colonoscopist. All patients enrolled in this study agreed to participate in it and signed an informed consent form prior to the colonoscopy.
The main purpose of the study to evaluate the usefulness of the Endo-AID artificial intelligence system in the detection of colorectal adenomas in consecutive patients for outpatient colonoscopy. The secondary aims were: - To evaluate the benefit of Endo-AID in adenoma detection rate by comparing endoscopists with high and low adenoma detection rate. - To evaluate serrated detection rate, advanced adenoma detection rate, adenoma detection rate according to the size (<= 5mm, 6-9mm,> = 10mm) and number of adenomas by colonoscopy. Stratification by location and morphology.
Retrospective data analysis of comparsion of 3 types of colonoscopes in daily practice (FUSE Full spectrum colonoscopy with 330° angle of view vs Pentax standard HD-colonoscopes and Pentax plus Endocuff): medical device of the category IIb (CE-marked device used within its intended purpose)
The purpose of this study is to assess the impact of multilevel factors on the quality of screening colonoscopy, reflected mainly by adenoma detection rate (ADR).
Missing polyps during colonoscopy is considered an important factor for interval cancer appearance especially in the ascending colon (AC). Aim of the study: To evaluate the contribution of retroflexion to adenoma detection in the AC. Patients-Methods: Prospective observational study included consecutive patients with complete colonoscopy between June 2017 and June 2018. The AC was examined in two phases. The first phase included two forward views from the hepatic flexure to the cecum and the second phase a retroflexion in the cecum, inspection till the hepatic flexure then redressing to forward view and reinsertion to the cecum.
The aim of this study is to evaluate the effect of ENDOCUFF VISION® (caps with soft, about 1 cm long lateral feet of rubber ("Endocuff") to flatten the colon folds) on ADR in a real-life setting (general practices) and in a homogenous patient collective (screening colonoscopies only). It is a prospective randomized multi centric study, with participation of at least 10 study sites (private practice). The study is an inverstigator-initiated trial (IIT). Depending on the randomization (closed envelope), the patients are examined with the standard instruments without or with ENDOCUFF VISION®. Group 1: screening colonoscopy with standard colonoscopes with ENDOCUFF VISION® Group 2: screening colonoscopy with standard colonoscopes without cap
Adenoma detection rate (ADR) is the most important parameter to measure outcome quality of (screening) colonoscopy. Since single improvements of imaging have not been able to improve ADR in many randomized studies, the present study tested the hypothesis that only multiple imaging improvements such as seen with two generation changes of colonoscopies - i.e. skipping one colonoscope generation - may be necessary before improvements in ADR can be measured. The investigators will test this hypothesis in the present randomized tandem study in 7 private practices in Hamburg and Berlin, in a pure screening colonoscopy setting, aiming at inclusion of 1200 patients > age of 55 years (screening colonoscopy cut-off in Germany). Exclusion criteria are symptomatic patients and colonoscopies planned for therapeutic reasons. Main outcome parameter is the ADR (rate of patients with at least one adenoma/all patients).
Colorectal cancer (CRC) is the most common tumor and the second leading cause of death in the Western world. The decrease in incidence and mortality by CRC in the population undergoing screening has been observed. Colonoscopy is the recommended method for detecting tumors in early stages, as well as identifying and resecting adenomatous polyps, which are the precursor lesions of most CRCs. Colonoscopy should be of high quality to decrease incidence and mortality by CRC and avoid interval cancer. The literature shows that colonoscopy does not prevent right colon lesions in the same way as the left colon lesions, with most of the interval cancers located in the right colon. Studies published so far show an increase in the adenomas detection rate (ADT) in the right colon in the second visualization of this segment and an increase between 2 and 10% if this second examination is performed with the proximal retroflexion maneuver.Retroflexion is a safe maneuver in expert endoscopists. The aim of our study is to evaluate the ADT in the right colon by means of a second visualization by performing proximal retroflexion or second frontal visualization at random in the CCR screening population.
To evaluate the efficacy, visibility of low volume polyethyleneglycol-simeticone (2-LPEG-S) for colonoscopy.
In this randomized controlled study, consecutive outpatients scheduled for elective colonoscopy were randomized into two groups. Group A patients (n = 150) used 2 L PEG before colonoscopy. Patients in group B (n = 150) were additionally advised to chew sugarless gum plus 2 L PEG, The overall quality of colonoscopy cleaning was evaluated using the Boston Bowel Preparation Scale by endoscopists who was blinded to the intervention. Difficulty of procedure, patients' tolerance, and adverse events were also evaluated.
