Observation of Major Duodenal Papilla (MDP) Clinical Trial
Official title:
Effect of Cap-assisted Esophagogastroduodenoscopy on Observation of Major Duodenal Papilla: a Randomized Non-inferiority Trial
Examination of major duodenal papilla (MDP) using a side-viewing duodenoscope is a golden standard. However, side-viewing duodenoscope is not available in some endoscopic centers. Cap-assisted esophagogastroduodenoscopy (Ca-EGD) using a transparent cap fitted to the tip of the scope has emerged as an alternative method for the observation of MDP. A recent study showed that complete examination of MDP could be achieved in 97% of patients. The investigators hypothesize that Ca-EGD is non-inferior to duodenoscope for the observation of MDP.
Interim analyses were planned to be performed by the data and safety monitoring board after data collection has been completed for 50% of the enrollment. ;
