Abstract:
Objective:To explore the diagnostic value of endoscopic ultrasonography (EUS) for duodenal accessory papilla.Methods:Data of 122 cases of duodenal accessory papilla diagnosed by EUS at the endoscopy center of the First Affiliated Hospital of Zhejiang University School of Medicine from February 28, 2006 to February 28, 2018 were analyzed and summarized.Results:Of the 122 duodenal accessory papilla cases, the age was 52.1±12.9, with more males than females. The most common site of duodenal accessory papillae was the descending part above the papilla (88/122, 72.13%), followed by the junction of duodenal bulb and descending part (29/122, 23.77%), and a small proportion of lesions located in the duodenal bulb (5/122, 4.10%). Duodenal accessory papillae were all solitary, whose diameter mostly ranged 0.5-1.0 cm (88/122, 72.13%), a smaller proportion of diameter larger than 1.0 cm (23/122, 18.85%), and only a few with diameter less than 0.5 cm (11/122, 9.02%). Most duodenal accessory papillae were hypoechoic (71/122, 58.20%) or moderate to low echogenic (35/122, 28.68%), and the echoes were mostly homogeneous. The mucosa layer was smooth, with a sphincteroid structure in the submucosa and below. The boundary of the duodenal accessory papillae was mostly clear (121/122, 99.18%) and characteristic lacunar cavity structures were often seen in the center (83/122, 68.03%). The surrounding intestinal wall was normal and no associated enlarged lymph nodes were found around the intestine.Conclusion:EUS can clearly show the structure of duodenal accessory papilla and adjacent organs, and is of high value for the diagnosis of duodenal accessory papilla.
