Summary

This study is a prospective, multicenter clinical trial. The study is planned to be conducted at a qualified clinical trial center, and 30 subjects are planned to be enrolled to evaluate the feasibility and safety of magnetically controlled capsule endoscopy (MCE) system in the examination of gastric disorders in patients with moderate to severe obesity (BMI ≥ 35 kg/m2).

Detailed description

Metabolic surgery, as one of the most important treatments for obesity, has been widely used worldwide. Esophagogastroduodenoscopy (EGD) is mostly used in the perioperative preoperative application of metabolic surgery to improve or exclude preoperative diagnosis, including gastrointestinal tumors, various types of upper GI mucosal lesions, esophagitis, esophageal hiatal hernia, gastrointestinal interstitial tumors, etc. However, EGD is an invasive examination and can cause discomfort without anesthesia, resulting in low patient compliance. In 2013, ANKON took the lead in developing the world's first capsule endoscope system that utilizes precise multi-dimensional rotational movement of a robotic arm and adaptive matching to achieve precise magnetic control, which is convenient for observing specific lesions from an appropriate angle and has been shown to have high diagnostic accuracy for gastric diseases (highly consistent with EGD, with sensitivity and specificity of 90.4% and 95.7%, respectively, and accuracy of 93.4%). It has been clinically proven that MCE is safe and effective in the upper gastrointestinal tract, but there is a lack of clinical systematic studies on its application to moderately and severely obese people.In summary, this exploratory study is designed to preliminarily verify the clinical feasibility and safety of MCE for upper gastrointestinal examination in moderately obese people (BMI ≥ 35 kg/m2).

Conditions

• Obesity

Interventions

Type	Name	Description
DEVICE	MCE for obese patients	Sequence of stomach examination: The stomach examination is performed sequentially according to the order of fundus, cardia, gastric body, angulus, antrum, and pylorus, which should ensure the integrity of the observation of each part of the stomach and achieve the purpose of comprehensive observation by means of different observation distances such as distant view and close view, and different observation angles such as front and side.
