P-HPB-09: A novel algorithmic approach for endoscopic ultrasound-guided biliary drainage based on factors influencing success of endoscopic ultrasound-guided transpapillary stenting

S19 ENDOSCOPIC ULTRASOUND / VOLUME 6 / SUPPLEMENT 1 / AUGUST 2017 2.7 ± 1.7 cm. Most patients were asymptomatic. The type of cystic lesions was intraductal papillary mucinous neoplasm (IPMN; n = 35), serous cystadenoma (n = 18), mucinous cystic neoplasm (MCN; n = 12), solid pseudopapillary epithelial neoplasm (SPEN; n = 9), cystic degeneration of other tumors (n = 4), simple cyst (n = 4), infectious (n = 2), and unclassified (n = 10). MCN and SPEN occurred exclusively in females. The most common site was head/uncinate (n = 42), followed by body (n = 21), tail (n = 20), neck/genu (n = 6), and multiple (n = 5). Majority of neoplasms did not have high-risk features of malignancy. Conclusions: Cystic neoplasms are increasingly being referred for EUS as a problem-solving tool, most common being IPMN. Absence of high-risk features on EUS reassures both patients and referring doctor. DOI: 10.4103/2303-9027.212308
