Filter by:In this study, we retrospectively analyzed the videos of combined upper digestive tract and small intestine examination under MCE, so as to clarify the feasibility and diagnostic efficacy of MCE in one-time examination of the upper gastrointestinal and small intestinal mucosa.
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.
Investigators aimed to present the patients who underwent laparoscopic gastrectomy with transoral specimen extraction.
Magnetically controlled capsule endoscopy (MCCE) is an outstanding opportunity for the painless endoscopic screening of the esophagus and stomach before small bowel examiantion. Further improvement in patients positioning might increase the esophageal transit time of the capsule endoscope and could improve the sensitivity and specificity of the esophageal MCCE investigation. Our present study aimed to compare the visualization of the esophagus (especially the Z-line) with different capsule swallowing protocols.
The purpose of this study is to evaluate the efficacy and tolerability of the maintenance treatment of Apatinib/Capecitabine after fluorouracil and platinum based first-line chemotherapy in advanced gastric cancer.
Probe-based confocal laser endomicroscopy (pCLE) is an endoscopic technique that enables real-time histological evaluation of gastric mucosal disease during ongoing endoscopy examination. However this requires much experience, which limits the application of pCLE. The investigators designed a computer-aided diagnosis program using deep neural network to make diagnosis automatically in pCLE examination and contrast its performance with endoscopists.
This is a randomized controlled trial to comparing the different simethicone administration strategies for esophagogastroscopy. Recent studies have indicated that the administration of simethicone before endoscopic examination could shorten the procedure time and improve the diagnostic rate of the gastric mucosal lesions. But the time interval between simethicone administration and the examination has not been fully determined. This study will test whether the time of taking simethicone before endoscopy could influence the performance of the procedure in a randomized controlled trial. The results may benefit the current clinical practice.
Our main objective is to evaluate the effect of Ocoxin-Viusid on the quality of life of patients with advanced stomach cancer and esophagogastric junction. The Ocoxin-Viusid nutritional supplement is expected to improve quality of life and tolerance to treatment with Chemotherapy.
By comparing dimethicone administration with/without subsequent repetitive position change before magnetically controlled capsule endoscopy (MCE) examination, the investigators aim to determine the efficacy of repetitive position change in improving gastric cleanliness for MCE examination.
In this pilot study the investigators test the hypothesis that gastric motility can be measured with an intragastric balloon.
