Brief summary

The goal of this clinical trial is to compare the safeness and effectiveness of traditional esophagogastroduodenoscope (EGD) and wired magnetically assisted capsule endoscopy (MACE) in the diagnosis of esophageal varices in biliary atresia (BA) patients. The main questions it aims to answer are: * Subjects who do wired magnetically assisted capsule endoscopy do not need to open the mouths during the process, this study also want to know whether wired magnetically assisted capsule endoscopy can reduce the generation of droplets. * Diagnostic accuracy between traditional esophagogastroduodenoscope and wired magnetically assisted capsule endoscopy in biliary atresia patients with esophageal varices. Participants will do either traditional esophagogastroduodenoscope or wired magnetically assisted capsule endoscopy.

Design outcomes

Primary

MeasureTime frameDescription
Aerosol-generating Amount1 dayAerosol-generating amount were measured using the MET ONE airborne particle counter \[DR-528 Handheld Particle Counter (Met One Instruments, Inc., Grants Pass, OR)\]. The device was placed on a platform at the same horizontal level as the patient lying flat, to capture airborne particles (sizes: 0.3-10 μm).Background environmental values were measured prior to each procedure and subtracted to determine net aerosol generation. Results are expressed as the total number of particles generated.

Secondary

MeasureTime frameDescription
Particles Generated Per Minute1 dayThe total number of particles of each size divided by examination time to calculate per-minute production; comparison between the two groups.
Number of Participants With Esophageal Varices1 dayWe recorded the number of participants who had esophageal varices after completion of the examination.
Number of Participants With Gastric Varices1 dayWe recorded the number of participants who had gastric varices after completion of the examination.
Questionnaire Assessments1 dayAfter the procedure, we assessed the patient's pain level using a Visual Analogue Scale (VAS) ranging from 0 to 10, where 0 indicates no pain and 10 indicates severe pain. We also evaluated the patient's willingness to undergo the same procedure again using a questionnaire scored from 0 to 5, where 0 indicates no willingness and 5 indicates strong willingness to repeat the procedure.
Examination Time1 dayExamination time is defined as the procedure duration, measured from insertion of the examination device into the participant's mouth to complete removal of the device.
Completion Rate1 dayCompletion rate was defined as the proportion of participants in whom successful examination of each anatomical segment (esophagus, stomach, and duodenum) was achieved.Successful completion for each segment was defined as the device reaching and examining the target segment.
