Late results in the endoscopic treatment of cicatricial bile duct strictures

Aim. To evaluate the late results of staged endoscopic treatment of patients with corrosive bile duct strictures.Materials and methods. The study included 41 patients with corrosive bile duct strictures varying in etiology and localization. The patients were observed over a seven-year period, most of whom had already undergone endoscopic treatment.Results. The technical success rate amounted to 100%. The procedure of staged stenting was completed in 34 out of 37 patients under observation. The clinical success rate, defined as the release of a stricture, reached 94%. In the postoperative period, the incidence of complications amounted to 8.8%. Only 2 out of 34 patients who had undergone stenting exhibited stricture recurrence.Conclusion. The staged placement of multiple plastic stents is characterized by high technical and clinical success rates while involving few complications, as well as a consistently low rate of stricture recurrence in the long-term period.
