Abstract：Objective To study the efficacy of cap-aided gastroduodenoscopy for the examination of the major duodenal papilla.Methods Seventy-two patients who underwent gastroduodenoscopy were randomly assigned to receive cap-aided gastroduodenoscopy (experimental group) and conventional gastroduodenoscopy (control group).The efficacy of visualization of the major duodenal papilla and other diagnostic indexes were compared between the two groups.Results In the experimental group, the percentage of patients who completed the whole examination of the major duodenal papilla was 91.7%, which was higher than 52.8% in the control group (P<0.001). In the experimental group,intubation from the esophagus to the end of major duodenal papilla took a significantly shorter time than in the control group (P<0.05). The detection rate of duodenal lesions was higher in the experimental group than that in the control group(16.7% vs 8.3%). However, no significant difference was found.Conclusions Compared with conventional gastroduodenoscopy, cap-aided gastroduodenoscopy can achieve a higher rate of whole examination of the major duodenal papilla and shorten the observation time of the esophagus to the end of the major duodenal papilla.
