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