Filter by: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.
Colonoscopy is one of the most common endoscopic procedures today. However, it sometimes can be a serious challenging situation both for the clinicians and patients. In this study, the investigators tried to determine which colonoscopic position allows easy, fast and comfortable way.
Esophagogastroduodenoscopy (EGD) become more and more common in diagnosing gastroenterology diseases. The investigators want to find which symptoms can support for positive endoscopic findings through this multicenter study.
Patients in our department endoscopic thyroidectomy were randomly divided into high position and low position established operating space group established operating space group. The thyroid size, patient BMI, operation time, and intraoperative blood loss were compared between the two groups.
Comparison of endoscopic thyroidectomy, robotic thyroidectomy and conventional open surgery, the safety of the operation, the timing of the operation and the complications.
Endoscopic thyroidectomy developed rapidly in recent years, and the most popular surgical approach was endoscopic thyroidectomy by bilateral areola approach, but some operative steps was required optimization. One of the most annoying problem was the smog blurring endoscopic lens during surgery. The researcher summarized a set of convenient foot-control exhaust method and carried out this prospective study.
This study is a randomized controlled trial comparing oxygen delivery by nasal mask with continuous positive airway pressure versus standard care (nasal cannula or standard facemask) during propofol-based sedation for gastrointestinal endoscopy procedures to reduce the incidence of hypoxia. The primary outcome will be the rate of oxygen desaturation below 90% for ≥15 seconds.
This study seeks to establish factors that influence the view at endoscopy. To achieve this patients, who have been already booked for endoscopy, will complete a questionnaire prior to their procedure. Demographic and endoscopist factors will also be ascertained. The view at endoscopy will then be reviewed and scored against a rating scale, which will be validated as a first phase of the study. Factors can then be sought that are associated with a good endoscopic view.
The use of endoscopy for the diagnosis of gastrointestinal diseases has continued to increase in recent years. Endoscopy provides an advantage over other noninvasive or minimally invasive procedures in that it allows both direct visualisation of the mucosa but direct and accurate sampling of abnormalities for histological examination. However standard endoscopy does have some limitations particularly with small lesions and pan mucosal changes. Some lesions may be entirely benign and require no further intervention but as a result of difficulty with accurate endoscopic characterization of lesions in many cases unnecessary biopsies or polypectomies are undertaken. Therefore any technology that can augment the use of standard endoscopy to minimise unnecessary intervention should be encouraged. IScan is a digital enhancement technique available with Pentax endoscopes. There have been other novel endoscopic advances for example, Narrow band imaging but these have not been adopted widely for a number of reasons including technical difficulties or patient tolerability. The aim of this study is to assess whether Pentax IScan technology is a reliable method of improving our recognition of macroscopic mucosal lesions compared to standard white light endoscopy
Hypothesis: Carbon dioxide gas use for endoscopic insufflation is safe and results in less abdominal distension and discomfort; it is equally effective as air in pediatric patients undergoing endoscopic procedures. Aim 1: Determine the occurrence and severity of abdominal discomfort and distension associated with endoscopic procedures at baseline, upon awakening from anesthesia, at discharge and at 4 hours after discharge in carbon dioxide group when compared to the air group. Aim 2: Determine if the expertise level of the endoscopist contributes to abdominal discomfort and distension following endoscopy, and whether this differs in the carbon dioxide group versus air group. Aim 3: Determine if carbon dioxide is as effective as air for insufflation.
