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.
Adenoma detection rate (ADR) is considered the single most important quality measure in colonoscopy and a higher ADR can reduce the risk of interval colorectal cancer (CRC). Several kinds of new endoscopes and accessories have been accessed to investigate the abilities of improving the ADR. Artificial intelligence (AI) and Endocuff vision are promising new devices to improve the ADR. However, the effect of combining AI and Endocuff vision on ADR remains unclear. The aim of this prospective randomized study is to compare the ADR of AI plus Endocuff vision, AI alone and standard colonoscopy examination.
The main purpose of the study to evaluate the usefulness of the Endo-AID artificial intelligence system combined with endocuff compared with endocuff in the detection of colorectal adenomas in consecutive patients for outpatient colonoscopy. The secondary aims were: - To evaluate the benefit of Endo-AID and endocuff 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.
This is a prospective equivalence colonoscopy study evaluating whether overall adenoma detection rate (ADR) is a reliable alternate for screening ADR. Overall indication includes screening, surveillance, and diagnostic indications.
To evaluate the impact of second forward view examination of the proximal colon on adenoma detection rate Inclusion criteria：Patients ≥18 years of age undergoing screening, follow-up monitoring, and diagnostic colonoscopy Exclusion criteria：①Cecal intubation failed. ②Have a history of colorectal surgery. ③Insufficient bowel preparation, inadequate bowel preparation quality (Boston Bowel Preparation Scale (BBPS)scores < 2 in any segment of the colon). ④Inflammatory bowel disease or intestinal tuberculosis. ⑤Familial polyp syndrome. ⑥polyp retrieval failure. ⑦Patients with coagulation dysfunction. Patients ≥ 18 years of age who came to our hospital's Digestive Endoscopy Center for screening, follow-up monitoring and diagnosis of colonoscopy. After successfully insert the cecum, colonoscope withdrawal to the splenic flexure, all polyps found during the withdrawal process were resection,then they were randomized to standard withdrawal colonoscopy or second forward view according to the random number table (1:1) to perform.
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).
Colonoscopy is a key technique in the detection and diagnosis of lower gastrointestinal diseases. High quality endoscopy results in better disease outcomes. However, the operant level of different endoscopists is significantly different.This study aims to construct a real-time quality monitoring system based on computer vision, named Endo.Angel, which is used to monitor the velocity of insertion of the endoscope, record the time of insertion and withdrawal of the endoscope, and remind endoscopists of the blind areas caused by intestinal segment slipping.
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.
