NCT04954677
With the rapid development of artificial intelligence technology, more and more deep learning technology has been applied to medicine. Our research is to develop a set of quality control system for magnetic capsule gastroscope using deep learning technology, and conduct a randomized controlled trial to verify its practical efficiency.

Clinical application of magnetically controlled capsule endoscopy : a prospective self-controlled trial
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.

A mini-sized MCE highlighted with a diameter of 9.5mm, a length of 24.5mm, and a weight of 3.0g has been developed. This new type of MCE is approximately 0.6 times the conventional MCE (27mm\*11.8mm) in volume and weight, and it is the smallest CE among all the reported capsules. Thus, this pilot study was conducted to clarify whether the mini-sized MCE can further optimize the process of swallowing the capsule and to verify whether the smaller size of the capsule will have influence on the examination procedure of the upper gastrointestinal tract and small intestine.

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%
NCT05228379
Examination of the small bowel has been considered a challenge for several anatomical (i.e. distance from external orifices, length) and physiological (i.e. active peristalsis) reasons. Conventional techniques of endoscopy are limited by length while radiologic examinations, such as barium studies, are insensitive for evaluating small bowel pathology. An ingestible miniature camera device capable of obtaining images of the whole small intestine was developed due to a need for the exploration of this "final frontier". The purpose of this article is to review and share our institution's results using small bowel capsule endoscopy, with special reference to the existing literature.

In December 2019, an outbreak of pneumonia associated with a novel coronavirus named as severe acute respiratory syndrome coronavirus 2 (SARSCoV-2) was reported in Wuhan city, China, and spread exponentially throughout China and other countries in the following weeks. It is recommended that elective endoscopies should be deferred during the COVID-19 outbreak for the potential transmission between patients and medical staff in the statements of Asian Pacific Society for Digestive Endoscopy (APSDE-COVID statements). Therefore, exploring an alternative for patients with the requirements of endoscopy during the outbreak is of great importance. Herein,the investigators developed an novel non-contact magnetically-controlled capsule endoscopy (Nc-MCE) system (Figure 1) adds a remote control workstation and a audio-visual exchange system to the original well-established MCE system. This study was a open-label, prospective, randomized controlled study approved by the institutional review board of Shanghai Changhai Hospital. It was designed to evaluate the diagnostic utility, safety, feasibility and patients acceptability of Nc-MCE in patients with an indication of endoscopy, and comparing it with the result of MCE.

The investigators aim to explore the feasibility of MCE in direct, real-time visualization of drug behavior in upper-gastrointestinal tract, which presented by the adhesion, distribution, and dissipation characteristics of dyed sucralfate gel.
NCT03662113
Video capsule endoscopy (VCE) has become an established technique to investigate the presence of small bowel pathology. But the limited battery life of capsules can lead to incomplete small bowel visualization. There is a rationale to use prokinetic agents prior to VCE reduce the chances of an incomplete small bowel examination via decrease gastric transit time (GTT). Investigators are aimed to prospectively compare the completion rate of VCE in pediatric patients receiving prokinetic with those receiving no prokinetic.

Wireless video capsule endoscopy (VCE) is a non-invasive technology that looks into small intestine and gives images of its lumen as the wireless capsule passes through it. It is used widely to access this anatomically difficult part of the body that cannot be seen via either colonoscopy or endoscopy. Currently various studies have been done that give multiple comparisons between various bowel preparation in terms of quality of the small bowel visualization. No studies have been done where simethicone (Gas-X) is ingested after capsule swallowing. We intend to give patients simethicone 1 hour after capsule ingestion for two consecutive hours and compare results of capsule endoscopy outcomes like small bowel transit time (SBTT), diagnostic yield (DY), small bowel visualization quality (SBVQ) and completion rate (CR).
NCT03482661
Patients referred for magnetically controlled capsule endoscopy (MCE) in the participating center from June 2017 to November 2017 were prospectively enrolled. Magnetic steering of MCE was performed after standard gastric examination. Capsule endoscopy completion rate (CECR), gastric transit time (GTT), pyloric transit time (PTT) and rapid gastric transit rate (GTT ≤ 30 min) were compared with the historical control group enrolled from January 2017 to May 2017.
NCT03441945
The research continuously enrolled 100 patients undergone MCCG between May to December 2017 as the intervention group with magnetic steering of capsule in the pylorus and duodenum, and randomly selected 100 patients before May 2017 from the database as the control group with passive movement of the capsule. The difference of the pyloric transit time (PTT) and duodenal papilla detection rate (DPDR) between the two groups were compared, and related factors were also investigated.
NCT02199626
This prospective pilot study of 40 pediatric patients with Crohn's Disease, that are candidates for endoscopic and imaging re-evaluation, examines the Given Diagnostic System and the second generation of colon capsule in comparison second generation of colon capsule endoscopy (CCE-2) to magnetic resonance enterography (MRE), small intestine contrast ultrasonography (SICUS) and endoscopy (upper and lower). This study aims 1. To evaluate and compare the accuracy of CCE-2 with MRE, SICUS and endoscopy in the evaluation of pediatric Crohn's disease. 2. To evaluate the safety of CCE-2 in pediatric CD.
