Filter by:This study aims to develop an algorithm to mitigate the noise generated by the high-flow nasal oxygen system for tracheal sound monitoring in deeply sedated patients.
The objective of this study is to assess the effectiveness of an AI-based reporting system for upper gastrointestinal endoscopy. The primary question that this study aims to address is whether the reporting system can enhance the completeness and accuracy of endoscopic reports when assisted by AI, as drafted by endoscopists. Patients will be randomly assigned to either the experimental group or the control group. In the experimental group, physicians will draft EGD reports with the assistance of the AI-based reporting system, while in the control group, physicians will use the conventional reporting system to draft EGD reports. At the same time, the AI-based reporting system will automatically generate a report of the EGD examination.
The goal of this observational study is to evaluate the effectiveness of an AI-based reporting system for upper gastrointestinal endoscopy. The main question it aims to answer is: Whether the AI-based reporting system can improve the completeness of the reports, which are drafted by endoscopists with the AI assistance. Participants will undergo upper gastrointestinal endoscopy examination as routine. The junior endoscopists will draft the report with the assiatance of the AI system. And the senior and expert endoscopists will draft the report using the traditional reporting system without AI assistance.
Stenosis is one of the most frequent complications in patients with Crohn's disease (CD). In particular, CD patients with intestinal strictures are often faced with short bowel syndrome after repeated or extensive surgical resection. Endoscopic management shows good efficacy and safety in the treatment of strictures in CD patients. The European Crohn's and Colitis Organisation (ECCO) guideline recommended that endoscopic balloon dilatation is suitable to treat short [<5 cm] strictures of the terminal ileum in CD. Recently, Lan et al. reported that endoscopic stricturotomy appeared to be more effective in treating CD patients with anastomotic stricture than endoscopic balloon dilatation. However, there is no prospective clinical studies evaluating the efficacy and safety of endoscopic stricturotomy in the treatment of fibrostenotic Crohn's disease. The trial aims to compare the efficacy and safety of endoscopic stricturotomy with endoscopic balloon dilation in the treatment of small bowel stricture in patients with Crohn's Disease.
The dissolution and absorption of oral drugs in the gastrointestinal tract is a complex process, which is affected by physiological factors such as transporters, metabolic enzymes, gene phenotypes, gastrointestinal diseases, intestinal flora and so on. Therefore, the investigators are planning to collect gastrointestinal mucosa tissues, gastric juice, saliva , feces and blood samples to investigate (1) the activity and abundance of metabolism enzymes/transports in different section of gastrointestinal tract, (2) the composition and physicochemical properties of gastric juice; (3) the distribution and abundance of bacterial in gastrointestinal mucosa, saliva, gastric juice and feces; (4) the composition and content of bile acid in gastrointestinal mucosa, gastric juice and plasma in Chinese volunteers who planning to undergo digestive endoscopy.
Air pollution sources in indoor area are one of the main factors for reducing indoor air quality of locations. A gastrointestinal endoscopy unit consists of the following area: procedural, recovery areas, and area for a disinfection and cleaning for equipment. This area is frequently exposed to the gastrointestinal gas expelled from patients and gas from electrocoagulated tissue through carbonation or electrocoagulation of neoplasms. This can be potential harmful component for respiratory health not only to medical practitioners but also to the patients who undergo endoscopic examinations. However, there has been scare data for the air quality check in the endoscopic unit.
The purpose of this study is to identify if performing diagnostic colonoscopy with a small plastic cap attached to the camera will improve performance of colonoscopies by physician trainees.
Esophageal cancer is a common malignancy with a very poor prognosis. The principal reason for its poor prognosis is that most tumors are asymptomatic and go undetected until they have spread beyond the esophageal wall and are unresectable. Significant reduction in esophageal cancer mortality will require successful strategies to diagnose and treat more cases at earlier, more curable stages of disease. A successful early detection program will require an accurate, patient-acceptable screening test, confirmatory tests that can localize precursor and early invasive lesions, and one or more curative therapies that are acceptable to asymptomatic patients. This project includes five studies designed to evaluate techniques that may be useful in such an early detection program: 1. The Cytology Sampling Study will estimate and compare the sensitivity of several cytologic samplers for identifying biopsy-proven dysplasia and cancer of the esophagus. 2. The Mucosal Staining Study will evaluate whether mucosal straining can improve endoscopic localization of esophageal dysplasia and cancer. 3. The Endoscopic Staging Study will evaluate how accurately endoscopic techniques can stage dysplasia and early invasive cancer of the esophagus. 4. The Endoscopic Therapy Pilot Study will evaluate the feasibility, safety, acceptability and preliminary efficacy of endoscopic therapies for removing or ablating focal high-grade dysplasias and early invasive cancers of the esphagus. 5. The Chemoregression Study will evaluate the ability of oral chemopreventive agents to reduce progression or cause regression of low-grade squamous dysplasia of the esophagus. This project will be carried out in Linxian, China, a county with extraordinary rates of esophageal cancer and a correspondingly high prevalence of the asymptomatic precursor and early invasive lesions that are needed for these studies. The project will be a collaborative effort of investigators from NCI, the Cancer Institute of the Chinese Academy of Medical Sciences, and several U.S. universities.
