About this study

Official title: A Prospective Study to Evaluate the Feasibility and Safety of Magnetically Controlled Capsule Endoscope System in Stomach Examination of Moderately and Severely Obese Patients

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).

Read the 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).

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • MCE for obese patientsDevice

    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.

Study groups in NCT05459714
Study groupRoleWhat they receive
MCE for obese patientsExperimentalAfter a standardized gastrointestinal preparation, the patient will undergo MCE examination. After completing the MCE procedure, the patient is evaluated for examination comfort and can then leave the hospital on his or her own and watch for capsule excretion.
Receives: Device: MCE for obese patients

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Participants With Complete Observation

    The number of participants with complete observation. Complete observation of the mucosa means over 90% of the mucosa observed in gastric cardia, fundus, body, angulus, antrum and pylorus.

    Measured: 2 weeks

Secondary outcomes (3)
  1. Gastric Examination Time

    Gastric examination time was defined as the time taken for the endoscopist to complete the gastric examination to his or her satisfaction

    Measured: 2 weeks

  2. The Total Number of Patients Who Who Had a Diagnosis of Positive Findings

    It was calculated using the following formula: number of patients with positive findings divided by the total number of patients that underwent examination.

    Measured: 2 weeks

  3. Evaluation of patient satisfaction through questionaires

    The investigators use a satisfaction questionnaire to evaluate the satisfaction of each patient, including ease of capsule swallowing, discomfort during the examination, discomfort after the examination and comfort level of MCE examination.

    Measured: 2 weeks
