Objective: To evaluate the value of endoscopic  treatment of bile duct lithiasis after BillrothⅡ gastrectomy.
 Methods: ERCP was used in 137 patients with bile duct lithiasis after BillrothⅡ gastrectomy. Of the 137 patients, 34 received EST and 4 EPBD.
 Results: ERCP was successfully performed in 109  of the 137 cases (79.6%), and falled in 28 (20.4%). Among 34 patients who had EST and 4 patients who had EPBD, stone extrection was successful in 35 cases (92.1%), and complicated by GI bleeding in 4 cases. There were no cases of GI perforation or death.
 Conclusions: The successful rate of EST is high in patients with bile duct lithiasis after BillrothⅡ gastrectomy, and endoscopic treatment has good therapeutic effects.
