Brief summary
The purpose of our study was to assess the performance of esophagogastroduodenoscopy automatic quality-control system in real-time quality control of EGD.
Detailed description
Investigators developed a real-time quality control system of esophagogastroduodenoscopy(EGD) named EGD automatic quality-control system (AQCS). Investigators carried a prospective multicenter randomized controlled trial to assess the performance of this system in quality control of real-time EGD, including detecting the early upper gastrointestinal cancer and precancerous lesions, assessing inspection completeness, mucosal visibility, time of EGD procedure and other indicators.
Interventions
EGD automatic quality-control system(AQCS),developed based on deep convolutional neural network (DCNN) models,could facilitate real-time detection of upper gastrointestinal lesions, assess inspection completeness and mucosal visibility, and calculate time of EGD procedure.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Detection rate of early cancer and precancerous lesions on upper gastrointestinal tract confirmed by pathological examination | 6 months | The primary outcome is the detection rate of early cancer and precancerous lesions on upper gastrointestinal tract confirmed by pathological examination per group. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Detection rate of early cancer and precancerous lesions on upper gastrointestinal tract in tertiary hospitals and secondary hospitals. | 6 months | Effect of detection rate of early cancer and precancerous lesions on upper gastrointestinal tract from tertiary hospitals and secondary hospitals with assistance of AQCS. |
| Mean inspection completeness of two groups. | 6 months | Inspection completeness includes taking standard images of each parts of esophageal and gastric cavity. |
| Mean inspection time of EGD procedure of two groups. | During procedure | Inspection time of EGD procedure is the time endoscopy inserting to withdrawing the mouth and does not include the time of biopsy. |
| Detection rate of early cancer and precancerous lesions on upper gastrointestinal tract from senior, intermediate and primary endoscopist with assistance of AQCS. | 6 months | Effect of detection rate of early cancer and precancerous lesions on upper gastrointestinal tract from senior, intermediate and primary endoscopist with assistance of AQCS. |
