Table 2 Comparison of ampulla of Vater visualization between FVE and CAE

From: Cap-assisted endoscopy increases ampulla of Vater visualization in high-risk patients

Ampulla of Vater visualization FVE CAE P value
 Completely visualized 52 (51.0%) 99 (97.0%) < 0.001
 Partially or not visualized 50 (49.0%) 3a (3.0%) < 0.001
  1. FVE forward-viewing endoscopy, CAE cap-assisted endoscopy
  2. aside-viewing endoscopy were performed
