This paper deals with the long-term effectiveness of metallic stents for the treatment of benign biliary strictures. Subjects were seven patients with benign strictures of bile duct undergone metallic stent. Another seven patients who received bilioenteric bypass under laparotomy in the same period were served as control. The follow-up period ranged from 8 months to 9 years. The causes of the strictures included post-choledochojejunostomy in three, chronic pancreatitis in two, and after operation for biliary stones in two cases. The mortality and morbidity of the subjects were 0%, 14% respectively. Both the duration from the admission to completion of the treatment and hospital stay was significantly longer in the metallic stent group than in the bypass group. Recurrent stenosis was encountered in one case in metallic stent group, while 0% in bypass group. The cumulative patency rates were 83%, 80%, and 75% at 1, 3 and 5 years respectively. Following the placements, a laxative and ursodeoxycholic acid had been prescribed in all patients to prevent the congestion of bile. Biliary scintigraphy was the most useful for making the accurate diagnosis of bile congestion. In conclusion, although the use of metallic stents for benign strictures is still controversial, considerate follow-up might enable the metallic stents for benign strictures to keep the long-term patency.
