Filter by:Common complications of the Boston keratoprosthesis type 1 (KPro) surgery include retroprosthetic membrane formation, glaucoma, and retinal detachment. Often pars plana vitrectomy (PPV) is performed at the same time as KPro surgery for different indications. It has been shown to reduce postoperative complications in comparison to when it is performed after the KPro surgery. Patients who receive a complete PPV with peeling of the anterior hyaloid membrane have a lower incidence of retroprosthetic membrane formation and less vision loss due to glaucoma when compared to patients with partial PPV or anterior vitrectomy. During a complete PPV, peeling of the anterior hyaloid membrane is a difficult step because visualisation is poor, but it can be improved using endoscopy. The investigators suggest that peeling of the anterior hyaloid membrane assisted by endoscopy during KPro surgery would decrease postoperative complications in comparison to a PPV done after KPro surgery and without endoscopy.
This project is a single-blinded randomized controlled trial investigating the effect of simulation-based teaching in learning gastroscopy for medical doctors.
This is an artificial intelligence-based optical artificial intelligence assisted system that can assist endoscopists in improving the quality of endoscopy.
This project is being performed to examine the results of duodenoscope cultures following standard of care cleaning and reprocessing.
This project is a prospective study investigating the education of medical doctors in gastroenterology with no prior experience to evaluate small bowel capsule endoscopies with a diagnostic sensitivity >90%
The main purpose of this study is to develop and gather validity evidence for a simulation-based test to ensure learning basic competence in gastroscopy.
This study is to compare propofol vs. midazolam with propofol for sedative endoscopy in patients with previous paradoxical reaction to midazolam. Patients who meet eligibility criteria will randomly assigned to propofol group or midazolam with propofol group. Then they will receive a sedative endoscopy with close monitoring. The primary outcome is the prevalence of paradoxical response during endoscopy.
This is an ambispective single-center cohort study of pediatric patients with portal hypertension and esophageal varices. The study was designed to evaluate the efficacy and safety of primary prophylaxis with endoscopic variceal ligation to prevent upper gastrointestinal bleeding compared to non-selected beta-blockers prophylaxis.
This single-blind prospective study is aimed to investigate the effect of antihistamine as an adjunctive sedative for the patients with histories of severe paradoxical reaction to midazolam during sedative endoscopy. Participating patients are to receive antihistamine intravenously in addition to midazolam. The primary outcome is the reduction of paradoxical reaction in the antihistamine combination group. The secondary outcome is to compare sedation quality, performance quality, reduction of total midazolam dose will be analyzed between antihistamine combination and midazolam only group.
Background: Gastric injections of Botulinum toxin A (BTA) may induce changes in gastric emptying and body weight, but results vary. BTA dose and depth of injection may affect efficacy. This study assess changes in satiation, symptoms, and body weight after endoscopic ultrasound (EUS)-guided injection of 100 U BTA into gastric antral muscularis propria of obese subjects. Methods: Open label study of twenty five healthy, obese adults (age=21-49 years, body mass index 35 = kg/m2) who received 100 U and were followed for 16 weeks. Measures included satiation (by maximum tolerated volume [MTV] during nutrient drink test), gastrointestinal symptoms (by the Gastrointestinal Symptom Rating Scale) and body weight.
