Purpose: To evaluate the necessity of metallic stenting of the sphincter of Oddi in malignant obstructive jaundice when the tumor is more than 2 cm from the papilla of Vater.Methods: Sixty-seven self-expandable biliary stents were used in 60 patients with extrahepatic lesions of the common hepatic or common bile duct and with the distal margin of the tumor located more than 2 cm from the papilla of Vater. Stents were placed above the papilla in 30 cases (group A) and in another 30 with their distal part protruding into the duodenum (group B).Results: The 30-day mortality was 15%, due to the underlying disease. The stent occlusion rate was 17% after a mean period of 4.3 months. No major complications were noted. Average survival was 132 days for group A and 140 days for group B. In group A, 19 patients survived {<=} 90 days and in eight of these, cholangitis occurred at least once. Of 11 patients in group A with survival > 90 days, only two developed cholangitis. In group B, 13 patients who survived {<=} 90 days had no episodes of cholangitis and in 17 with survival > 90 days, cholangitis occurred in three. There is a statistically significant difference (p < 0.05) regarding the incidence of cholangitis in favor of group A.Conclusions: In patients with extrahepatic lesions more than 2 cm from the papilla and with a relative poor prognosis ({<=} 3 months), due to more advanced disease or to a worse general condition, the sphincter of Oddi should also be stented in order to reduce the postprocedural morbidity.
