Detachable String Magnetically Controlled Capsule Endoscopy for Patients with AUGIB

Detachable String Magnetically Controlled Capsule Endoscopy for Patients with Acute Upper Gastrointestinal Bleeding: a Prospective Study

Use CE for pre-examination of patients with AUGIB symptoms in emergency centers may reduce the need for emergency electronic gastroscopy and have certain advantages in clinical work. Patients with low-risk lesions can be discharged without the need for EGD and hospitalization, greatly improving the utilization of medical resources.

The investigators plan to conduct exploratory research by sequentially performing DS-MCE and EGD examinations on AUGIB patients with stable hemodynamics, using EGD as the gold standard to evaluate the sensitivity of DS-MCE in diagnosing upper gastrointestinal bleeding lesions and active bleeding.

Inclusion Criteria:

• No gender limit, age ≥ 18 years
• Presenting to the emergency department with melena or hematemesis
• Hemodynamically stable at presentation
• No endoscopic examination has been performed due to this bleeding
• Agree to participate in this clinical trial and sign an informed consent form

Exclusion Criteria:

• Patients with acute active massive bleeding or hemodynamic instability (blood pressure < 90 mmHg and heart rate > 120 beats per minute)
• Patients with Hematochezia
• Hemodynamics remained unstable after fluid resuscitation
• Known or suspected intestinal obstruction, stenosis, or fistula
• Severe motor disorders such as asthma, swallowing disorders, or gastric paralysis
• History of abdominal surgery that affects the normal structure of the digestive tract in the past
• When capsule retention occurs, the problem cannot be solved through surgery due to subjective or objective reasons
• Implantable medical devices such as pacemakers, electronic cochlear implants, drug infusion pumps, and neural stimulators are installed inside the body, except for MRI compatible products
• Pregnant women
• Those who require MRI examination before capsule endoscopy discharge
• Suffering from severe cardiovascular and pulmonary diseases (such as severe myocardial infarction, arrhythmia, heart failure, and respiratory failure)
• Refuse MCE or gastroscopy examination
• The researchers believe that the subjects have any other factors that are not suitable for participation in the study
