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.
