The goal of this clinical trial is to develop and verify the auxiliary role of the artificial intelligence system in pancreatic ultrasound endoscopic scanning.The main questions it aims to answer are as follows: 1.The comparison of the image recognition accuracy between the artificial intelligence system and the ultrasound endoscopist; 2. Whether the artificial intelligence system can improve the efficiency of the pancreatic scanning for the ultrasound endoscopist. Participants will undergo pancreatic EUS with or without the assistance of the artificial intelligence system.
1. Age ≥18 years old, <80 years old 2.Patients who need endoscopic ultrasonography of pancreas; 3. Agree to participate in this study and sign the informed consent form.
Poor physical condition, including hemoglobin ≤8.0g/dl, severe cardiopulmonary insufficiency, etc.
Anesthesia assessment failed
Pregnancy or breastfeeding
In the acute stage of chemical and corrosive injury, it is very easy to cause perforation
Parallel
artificial intelligence system
DevicePatients will undergo EUS examination with the assistance of artificial intelligence(AI) system.
Accuracy
The number of correctly classified images divided by the total number of images.
The completeness for standard station scanning
This was calculated as the number of stations successfully scanned divided by the total number of stations that should have been scanned.
Cohen's kappa coefficient.
This data is to evaluate the agreement between the model and the endoscopists.
The completeness of anatomical landmarks
It calculated as the number of anatomical structures successfully scanned divided by the total number of structures that should have been scanned.
The completeness for standard stations and anatomical landmarks per individual
The completeness of stations and anatomic landmarks of biliopancreatic endoscopic ultrasonography by different endoscopists in the AI system assisted group and the control group were compared.
Operation time
In addition to puncture, elastography, and enhanced ultrasound to observe the lesion or treatment, it is also used to observe the time of biliopancreatic system.
