Brief Summary

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

In this study, a single-center, prospective, self-control, and blind design was adopted.

Detailed Description

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

It is planned to enroll 100 patients with solid pancreatic masses who are to be diagnosed with contrast-enhanced harmonic endoscopy ultrasonography (CH-EUS) follow by EUS-guided fine-needle aspiration (EUS-FNA). First, all patients will be diagnosed both by the AI-assisted diagnosis system and the endoscopists under CH-EUS; Second, to compare the EUS-FNA under the guidance of the AI-assisted ultrasound diagnosis system and the EUS-FNA under manual identification, patients were randomly assigned to undergo EUS-FNA with or without the guidance of AI-assisted diagnosis system for the first two passes.

the artificial-EUS-FNA group

the first two passes were made without the AI-assisted diagnosis system guidance during EUS-FNA, and then two passes were made under guidance from the AI-assisted diagnosis system

Group Type EXPERIMENTAL

artificial-EUS-FNA

Intervention Type PROCEDURE

The ultrasound endoscopists manually determined the region of interest (ROI) according to CH-EUS, and punctured 2 needles in the tumor area with a 22G needle, and each needle moved 15-20 times back and forth in the lesion. After puncture, insert the needle core, rinse the needle with 0.1ml sterile saline, and further apply air flushing to ensure that each tissue is sent to the slide.

AI-EUS-FNA

Intervention Type PROCEDURE

In the AI-assisted diagnosis system, the assisted targeting EUS-FNA unit is applied, and the ultrasound endoscopist selects the region of interest (ROI) according to the thermogram to perform targeted EUS-FNA puncture(2 needles in the same way).
