Factors influencing outcome in patients with postoperative biliary strictures.
We reviewed our experience from 1955 to 1979 with benign postoperative biliary strictures to determine which factors were associated with a favorable outcome. Patients operated on from 1970 to 1979 were significantly more likely (p less than 0.01) to achieve a good result (86 percent) than were patients undergoing surgery between 1955 and 1969 (68 percent). An inverse correlation (r = -0.96, p less than 0.05) was present between the number of previous repairs and the percentage of good results. Patients referred without a previous repair were most likely to achieve a good result (86 percent). Roux-Y jejunal reconstructions were associated with the best results (p less than 0.01). In recent years Silastic transhepatic stents were used in 20 patients with hilar strictures; 18 (90 percent) achieved good results. Patients stented for the shortest period (less than 1 month) were less likely to achieve a good outcome than those stented for longer periods (p less than 0.025). Patients with difficult hilar strictures who were stented for more than 9 months were more likely to have a good result if a changeable Silastic transhepatic stent was employed (p less than 0.01). This analysis suggests that early referral, Roux-Y jejunal reconstruction, judicious use of Silastic transhepatic stents, and prolonged stenting of hilar strictures will improve the outlook in patients with postoperative biliary strictures.U
