Cap Assisted Forward-Viewing Endoscope vs Side-Viewing Endoscope for Examination of Major Duodenal Papilla

Cap Assisted Forward-Viewing Endoscope vs Side-Viewing Endoscope for Examination of Major Duodenal Papilla

Examination of major duodenal papilla (MDP) using a standard forward-viewing esophagogastroduodenoscopy (S-EGD) is limited. Until now, side-viewing duodenoscope is the modality of choice to examine the MDP. Cap assisted esophagogastroduodenoscopy (CA-EGD) uses a cap fitted to the tip of the scope that can depress the mucosal folds and thus improve visualization and examination of MDP. The aim of this study is to compare CA-EGD to side*viewing duodenoscope for complete examination of MDP.
