A remnant choledochal cyst after choledochal cyst excision treated with a lumen-apposing metal stent: a case report

다국어 초록 (Multilingual Abstract)

A lumen-apposing metal stent (LAMS) is a saddle-shaped stent with large flanges at both ends, thereby preventing stent migration andhelping with approximation of the adjacent structures. We report the case of a 25-year-old female with remnant choledochal cyst whichwas successfully treated with LAMS after initial treatment failure with a plastic stent. Although complete excision of the cyst is the definitetreatment of choledochal cysts, endoscopic ultrasonography-guided cystoduodenostomy can be considered in cases wherein surgeryis not feasible and dysplasia is not present. LAMS may be preferred to plastic stents for effective resolution of remnant choledochalcyst and prevention of ascending infection.
