Magnetic-controlled Capsule Endoscopy vs. Gastroscopy for Detection of Gastric Diseases

Magnetic-controlled Capsule Endoscopy vs. Gastroscopy for Detection of Gastric Diseases: A Prospective Self-controlled Comparative Multicenter Trial

A new Magnetic-controlled Capsule Endoscopy (MCE) was developed by ANKON and got SFDA's approval in China in 2013. It has recently been evaluated to compare the diagnostic accuracy of MCE with that of standard gastroscopy for gastric diseases in 70 patients with encouraging results (In Press). To further testify the diagnostic accuracy of MCE for both the diffuse and focal diseases in stomach, we performed this single-blinded multi-center prospective study compared MCE with gastroscopy in patients with gastric symptoms and indication for upper GI Endoscopy.

Inclusion Criteria:

• Patients presented with gastric symptoms and ready for the first Upper GI endoscopy
• Patients with known focal gastric diseases: gastric ulcer, gastric polyps, early gastric cancer, gastric stromal tumors and so on.

• Patients with impaired bowel movement from ileus or organic digestive diseases
• Patients with known large and obstructing tumors of the upper GI tract
• Patients after upper GI surgery or abdominal surgery altering GI anatomy
