Mohamed Abdelhafez et al. Comparison of cap-assisted endoscopy vs. side-viewing endoscopy
for examination of the major duodenal papilla: a randomized, controlled, noninferiority
crossover study
This noninferiority investigation demonstrates that cap-assisted endoscopy and endoscopy
with a side-viewing endoscope have similar success rates regarding complete visualization
of the major duodenal papilla; however, the side-viewing endoscope gives a better
overview of the periampullary region.
