Standing-type magnetically guided capsule endoscopy versus gastroscopy for gastric examination: multicenter blinded...

Area of Science:

• Gastroenterology
• Medical Devices
• Diagnostic Endoscopy

Background:

• Conventional gastroscopy is the standard for diagnosing gastric conditions but can be invasive and requires anesthesia.
• There is a need for less invasive and more comfortable diagnostic tools for upper gastrointestinal examination.

Purpose of the Study:

• To evaluate the feasibility and safety of standing-type magnetically controlled capsule endoscopy (SMCE) compared to conventional gastroscopy for gastrointestinal examination.
• To assess the diagnostic agreement and patient satisfaction between SMCE and gastroscopy.

Main Methods:

• A prospective, multicenter, blinded study comparing SMCE and gastroscopy in 161 patients.
• Patients underwent SMCE followed by gastroscopy with intravenous anesthesia.
• Compliance rates for lesion detection, capsule retention, adverse events, and patient satisfaction were recorded.

Main Results:

• SMCE demonstrated high overall compliance rates (94.41%) in detecting gastric lesions compared to gastroscopy.
• Both procedures identified 64 pathological outcomes, with 50 detected by both.
• No capsule retention or adverse events were reported for SMCE.

Conclusions:

• Standing-type magnetically controlled capsule endoscopy is a feasible and safe procedure for gastric screening.
• SMCE shows equivalent diagnostic agreement with conventional gastroscopy and may serve as a valuable alternative, particularly for patients avoiding anesthesia.
