Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The primary objective for this study is to compare the safety and validity of two endoscopic ultrasonography (EUS) systems (GF-UE260-ME2 and EG-UR5-S50) used for clinical performance and establish a relative EUS performance assessment system and clinical case data to provide support for the product performance improvement.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This research is a random, opening and parallel-controlled clinical test. Tested device model: The EG-UR5 ultrasonic endoscope manufactured by SonoSscope Medical Crop. That used with the HD-500 image processor, HDL-500X light source and S50Exp ultrasonic color doppler instrument .

Compared device model: The GF-UE260-ME2 ultrasonic endoscope manufactured by Olympus and its compatible light source, image processor and ultrasonic instrument.

To scientifically compare the clinical performances of the test model and the compared model, the enrolled objects would be randomly distributed to the tested group and the compared group to conducted the examination with the tested model and the compared model respectively.

EUS will be performed in the standard fashion by one of the experienced endosonographers in the unit. Once the EUS is complete, the procedure will be stopped and the echoendoscope withdrawn from the patient.

1. Check Points Providing optical images of the human upper gastrointesinal tract (including esophagus, stomach and duodenum) for observing, diagnosis and treatment, and for the ultrasonic check and diagnosis for the upper gastrointestinal tract and surrounding organs.
2. Test Items 1. Ultrasonic and endoscopic image quality assessment 2. Device controllability assessment 3. System safety assessment 4. System stability assessment

The data are recorded in the CRF, including patient information, clinical assessment for the usage of the endoscope and device operation, thus to perform a comprehensive assessment whether the safety and validity of this product can meet the clinical requirements.
