ABSTRACT
OBJECTIVE:
To evaluate long-term patency rates of a novel percutaneous threefold balloon dilatation protocol in benign anastomotic biliary strictures.METHODS:
Patients with a benign biliary stricture after hepatobiliary surgery or liver transplantation, untreatable with endoscopy, underwent a percutaneous treatment cycle consisting of a 20-min balloon dilatation session on day one, repeated on days three and five. No catheters were left behind after the last dilatation session. Technical and clinical success as well as complications were analysed. Mean primary and secondary patency times were assessed. Cumulative primary and secondary patency rates at 6 months and 1, 2 and 3 years were determined.RESULTS:
Seventy patients underwent 135 dilatation treatment cycles (mean 1.9) with a technical success rate of 99%. Clinical success was achieved in 87% of the patients. Fifty-eight of 135 (43%) patients had minor and 15/135 (11%) had major complications. Mean primary and secondary patency times were 26 months and 46 months, respectively, with a median follow-up of 69 months. Cumulative primary patency rate at 6 months was 67%, at 1 year 56%, at 2 years 41% and at 3 years 36%. The cumulative secondary patency rate at 6 months was 83%, at 1 year 79%, at 2 years 70% and at 3 years 64%.CONCLUSION:
In benign anastomotic biliary strictures, a percutaneous threefold balloon dilatation treatment is effective. As long indwelling catheters are avoided, patient comfort improves. KEY POINTS ⢠Percutaneous threefold balloon dilatation treatment is effective in benign anastomotic biliary strictures. ⢠As indwelling catheters after dilatation are avoided, patient comfort improves. ⢠The dilatation protocol can be repeated efficiently in case of recurrent stricture.Palavras-chave
