Upper oesophageal images and Z-line detection with 2 different small-bowel capsule systems

摘要

Transmission of oesophageal images may vary between different small-bowel capsule endoscopy models.A retrospective review of 100 examinations performed with 2 different Small-bowel capsule endoscopy(SBCE) systems(PillCam and MiroCam) was performed.The oral cavity/aero-digestive tract(i.e.,tongue,uvula and/or epiglottis) was captured/identified in almost all(99%) of PillCam videos but in none of MiroCam cases,P < 0.0001.Furthermore,oesophageal images(i.e.,from the upper oesophageal sphincter to the Z-line were captured in 99% of PillCam videos(mean ± SD,60.5 ± 334.1 frames,range:0-3329 frames) and in 66% of MiroCam cases(mean ± SD,11.1 ± 46.5 frames,range:0-382 frames),P < 0.0001.The Z-line was identified in 42% of PillCam videos and 17% of MiroCam,P = 0.0002.This information might be useful when performing SBCE in patients with high risks for aspiration.
