Filter by:The investigators will review video-recordings of three randomized, controlled trials (NCT01535326, 01699399, and 01894191) comparing air insufflation, water immersion and water exchange during colonoscopy. These studies were all conducted at Buddhist Dalin Tzu Chi Hospital.
Comparing the efficacy of cold snare polypectomy with endoscopic mucosal resection
To prospectively validate the SERT (Sydney EMR Recurrence Tool) scoring system for adenoma recurrence rates around the endoscopic mucosal resection (EMR) scar after wide field-EMR with thermal treatment applied to the defect margin. The primary aim of the study will be to ensure the safety of this approach and there will be constant monitoring to ensure that this is the case.
The purpose of this study is the investigation of new host-microbiome interactions promoting adenoma formation and adenocarcinoma progression. For that purpose, the investigators will collect saliva, stool and colon biopsy specimens from patients referred to colonoscopy or surgical resection of colorectal tumor. Besides, a questionnaire about diet, lifestyle and medical history will be collected. Sample analysis will involve simultaneous characterization of host and microbiota genomic and transcriptomic components.
Evaluate the safety and efficacy of the Rezum System for the treatment of BPH
Evaluate the effect of the NxThera BPH Rezum System on prostate tissue in subjects suffering from LUTS symptoms secondary to benign prostatic hyperplasia (BPH).
The monitoring and prognosis of patients with familial polyposis adenomatous rests on analysis of the transitional mucosa at the anal margin and especially on the tracking, characterization and resection of lesions of dysplasia type of high grade at the duodenal level, after total proctocolectomy. Currently, endoscopes with axial or lateral vision are used. The FUSE technology allows the simplification or even the improvement of patient surveillance with a 245° vision (versus150° in case of classical gastroscope). The use of a second screen to enlarge the field of view may allow both analysis of duodenum and the main and accessory papilla with one single endoscope and to decrease the number of omitted lesions .
The coloscopy is considered as the gold standard for screening and resection of colorectal adenomas. However the literature reports that the rate of omitted adenoma is still high (24 to 41%). The development of the FUSE system (Endochoice, USA) allows a larger field of view with a projection onto 3 screens (330° vision). A pilot study and a randomized multicentre has demonstrated the feasibility with a significant improvement of the rate of detected adenomas. This first study in France concerning this technology has the objectives to demonstrate the feasibility in France, the safety and to compare the rate of detected adenomas with data of the literature.
The purpose of the study is to assess the efficacy and morbidity of biliairy radiofrequency ablation for the treatment of dysplastic endobiliairy residual lesions (low-grade dysplasia or high-grade dysplasia) after endoscopic ampullectomy for ampullary adenoma.
Adenoma detection in the main goal of screening colonoscopy. In order to detect adenomas it is mandatory to spend a long enough time investigating the colonic mucosa. A minimum observation time of 6 minutes has been proposed as a quality criterion for screening colonoscopy. However, different locations of the colon (proximal, distal) may require specific observation time periods. The colon can be divided into a proximal (right) and distal (left) part. Until now, it is unclear whether observation time has a significant impact on adenoma detection in both parts of the colon. The aim of this study therefore is to conduct a trial in which side-specific observation times and adenoma detection rates are measured in order to investigate this correlation in particular for the right colon.
