Little is known about the long-term results after surgical correction of iatrogenic bile duct injuries. In 72 (64.9%) out of 111 patients who were treated at the University of Mainz between 1.1. 1964 and 31.21. 1987 it was possible to obtain reliable observations on the course of the disease after an average period of 9.4 years. After a follow-up time of 23 years only 20% (end-to-end anastomosis) and 34% (choledocho- or hepaticojejunostomy) were free of complaints. Within 10 years 35% were relaparotomized after choledocho- or hepaticojejunostomy and 58% were relaparotomized after end-to-end anastomosis because of complaints. After choledocho- and hepaticoduodenostomy 20 out of 22 patients required a second operation. Long-term results were statistically depended on the localization of the stenosis, the number of interventions and the operation method. Long-term results were independent on the fact if the lesion was primarily seen or not.
