NCT07336680
The goal of this clinical trial is to evaluate whether intravenous ondansetron can improve patient tolerance and reduce discomfort during unsedated emergency esophagogastroduodenoscopy (EGD). The main questions it aims to answer are: * Does pre-procedural administration of ondansetron improve patient cooperation during emergency EGD? * Does it improve endoscopic field visibility and improve the success rate of initial endoscopic hemostasis？ * Does it reduce the operator's perceived workload or stress? Researchers will compare patients who received intravenous ondansetron with patients who received placebo to see if ondansetron can reduce patient discomfort and improve patient cooperation, therefore improve the quality of the procedure. Participants will receive either intravenous ondansetron and dyclonine hydrochloride mucilage or intravenous saline and dyclonine hydrochloride mucilage prior to the endoscopic procedure.
NCT06689046
Endoscopic procedures are widely implemented to diagnose both malignant and benign diseases. Nausea and vomiting is a common complication after anesthesia. Yet, nausea and vomiting after endoscopic procedures are not dully established. The primary aim of the study is to assess the incidence of postoperative nausea and vomiting in patients who underwent esophagogastroduodenoscopy. The secondary aim is to identify possible risk factors, both related to the patients and the procedure itself.
NCT05407870
During endoscopy, the patient is sedated to relieve pain and improve the ease of the procedure. Sedation endoscopy using propofol is effective, but has the disadvantage that cardiopulmonary side effects are frequently observed. However, etomidate is known to have hemodynamic and respiratory stability.The purpose of this study was to compare the efficacy and safety of etomidate and propofol in sedated gastric endoscopic submucosal dissection.
NCT04720924
The purpose of our study was to assess the performance of esophagogastroduodenoscopy automatic quality-control system in real-time quality control of EGD.
NCT05504434
Several infectious outbreaks have been described in the literature as a result of contaminated endoscopes. These endoscopes cannot be sterilized and require an extensive cleaning process in which breaches of cleaning protocols, endoscope damage or the formation of biofilm can prevent proper disinfection. The risk of endoscopy associated infection (EAI) and colonization due to contaminated endoscopes is still considered to be low. However, it is likely that there is severe underreporting of outbreaks due to a lack of recognition or assuming an infection to be endogenous. Due to the sheer volume of upper-gastrointestinal endoscopy worldwide, even with a low risk of EAI, the number of affected patients is significant. In response, several manufacturers have turned to the production of single-use endoscopes that eliminate the risk of exogenous infections. There are single use duodenoscopes on the market that almost seem to match the performance of reusable duodenoscopes. A new single use sterile gastroscope, Ambu aScope gastro, has been developed whose performance has not been previously described in patients. This multicenter single arm consecutive case series study will test the performance of these single use gastroscopes in patients undergoing esophagogastroduodenoscopy.
NCT03883035
The aim of our study was to develop an automatic quality-control system and assess the performance of this system in quality control of esophagogastroduodenoscopy.
NCT04168294
It is commonly recommended that patients should refrain from driving for 24 hours after sedation for endoscopy，however，this recommendation has been queried recently．To investigate the effect of sedation on early postoperative cognitive function in patients undergoing endoscopy.
NCT02215291
Prospective, multi-site registry with longitudinal follow up for patients undergoing EGD or endoscopy. The primary objective is to provide a collection of patient NvisionVLE™ procedural data for participating physicians, including, but not limited to, imaging data, clinical utility data, demographics, pathology, treatment, and surveillance.
NCT03070379
At recent, the number of patients who underwent sedated esophagogastroduodenoscopy has been on the increase. For such patients, whether topical pharyngeal anesthesia is needed remains to be controversial. European Society of Gastrointestinal Endoscopy, European Society of Gastroenterology and Endoscopy Nurses and Associates, and the European Society of Anaesthesiology Guideline for non-anesthesiologist administration of propofol for GI endoscopy have not made any recommendation, because the role of pharyngeal anesthesia during propofol sedation for upper digestive endoscopy has not been assessed. Our study aimed at investigating whether topical lidocaine pharyngeal anesthesia could benefit patients who underwent esophagogastroduodenoscopy under propofol sedation.
NCT02031900
This is a single center, single arm, open label observational trial of patients undergoing EGD. The primary objective of this clinical trial is to evaluate the ability of physicians to position the NvisionVLE Optical Probe to acquire an image of an area of the esophagus to identify and discriminate abnormal areas of tissue from normal.
