- W3030897757 abstract "Objective To evaluate the feasibility of simultaneous endoscopic bilateral placement of self-expandable metal biliary stents. Methods A total of 9 patients with hilar malignancy of Bismuth type Ⅱto Ⅳ were enrolled in the current study, with a mean serum bilirubin at 162. 8 ± 193.8μmol/L before the procedure. Two guide wires were selectively inserted into the left and right intrahepatic ducts and kept in site. After aggressive dilatation for both sides, the metal stents were deployed one by one bilaterally. Success rate of the procedure, remission of jaundice, early complications, and short-term clinical outcome were observed. Results The procedure was succeeded in all patients with Y type stent in 2, plastic stent transition in 1 and parallel stenting in 6, which took an average time of 38. 1 min. The most convenient way was the parallel method with both distal ends of the stents remaining at outside of papilla. The serum bilirubin returned to normal level within 3 weeks in all patients except 1, and no major complications were observed. Conclusion Simultaneous endoscopic bilateral metal stent placement is technically feasible and safe, with the benefit of prompt and effective control of jaundice and infection, caused by hilar tumors. A better method is to place specially designed endoprotheses in parallel and leave the distal ends outside papilla.Key words: Biliary tract neoplasms ; Cholangiopancreatography, endoscopic retrograde ; Self-expandable metallic stent" @default.
