NCT06958250
This feasibility study aims to assess the safety and effectiveness of the Novel Endoscopic Bite Block. The device will be utilized in subjects undergoing routine outpatient upper endoscopy. The investigator hypothesizes that its innovative design will reduce complications associated with bite block positioning, thereby improving procedural efficiency and patient safety.
NCT06555276
This is a multi-center and retrospective cohort study to evaluate the efficacy and safety of disposable linear cutting staplers and components in soft tissue resection, transection and anastomosis.
NCT06273319
To compare desaturation and respiratory complications by applying oxygen therapy with double nasal cannula to patients who are planned to undergo gastrointestinal endoscopy.
NCT04479423
Magnetically controlled capsule endoscopy (MCE) is a noninvasive technique (90.4% sensitivity, 94.7% specificity and 93.4% accuracy) without requiring sedation or air insufflation, which makes it welcomed by most of participants. However, due to the large size of the stomach, clear views are obtained with the stomach distended. Participants were asked to drink 1000ml water for gastric preparation in a short time according to the standard procesure. It is hard for some participants especially the old and can cause discomfort. If the capsule stays in the stomach for a long time (\>4 hours), it will affect the completion rate of small intestine examination and be inconvient to both of the endoscopist and patient. It is a promising way to fill the stomach with carbonated drinks in some diagnosis and treatment methods. A study using carbonated drinks for gastric filling in the procedure of multi slice spiral computed tomography (MSCT) showed higher diagnostic rate for gastric cancer (85%VS80%). Rapid filling and absorption, greater comfort feeling and little pressure changes lead to higher acceptance of participants. So, researchers have a novel idea using soda water to take place of pure water in the gastric preparation. The combination of gas and liquid in gastric filling greatly reduces the amount of fluid that participants need to drink, which makes the shorter preparation time and less feeling of fullness. In a pilot study before, investigators found the usage of soda water obtained similar gastric distention score and shorter gastric transit time (GTT) than standard preparation method. This prospective, single blind, randomized controlleds trial aimed to prove the safety and efficiency of soda water in the process of gastric preparation and explore the impact on the follow-up small bowel examination.
NCT05801055
Endoscopy is the diagnostic modality for most gastroduodenal diseases. During endoscopy mucus and foam may actually interfere with the visibility of the stomach mucosa. So the mixture of mucolytic ( N-acetyl cysteine) and anti-foaming agents ( simethicone) agents may disperse the bubbles and mucus in the stomach and enhance gastric visibility. This unique combination drink given 20-30 minutes prior to endoscopy is absolutely safe. There are previous studies from India, which was retrospective study. So, we have planned to conduct this randomized controlled trial on this issue. Adult patients undergoing diagnostic endoscopy will be randomized and one group (100 patients) will be given the combination drink whereas another group 9100 patients) will undergo an endoscopy after overnight fasting only, as a placebo drink may actually hamper the endoscopic visibility. Our primary outcome, gastric visibility will be assessed using a standard visibility scoring system.
