Abstract

Objective: To describe, assess the feasibility of, and quantify the long-term patency achieved with percutaneous transhepatic biliary dilation using the anastomotic biliary stricture (ABS) oversized balloon dilation technique as a single-step procedure for the treatment of benign anastomotic biliary strictures following hepatobiliary surgery. Materials and Methods: This was a retrospective, two-center study including 16 consecutive cases of symptomatic benign biliary-enteric strictures. After assessment of the diameter of the bile duct by computed tomography or magnetic resonance imaging, the strictures were dilated with oversized balloons (40-50% larger than the bile duct diameter) and an external biliary-enteric drain was placed. After drain removal, clinical symptoms and laboratory test results were evaluated every three months, whereas follow-up magnetic resonance imaging was performed at 30 days out and follow-up computed tomography was performed at 6 and 12 months out. Results: The mean follow-up time was 31.8 ± 8.15 months. Kaplan-Meier-estimated 1-, 2-, and 3-year patency rates were 88.2%, 82.4%, and 82.4%, respectively. There was one major complication—a small dehiscence of the anastomosis—which extended the catheter dwell time. Minor complications occurred in two cases—one small perihepatic hematoma and one segmental thrombosis of the left portal branch—neither of which required further intervention. Conclusion: The single-step ABS oversized balloon dilation technique is a feasible treatment for benign anastomotic biliary-enteric strictures. The technique appears to be associated with high rates of long-term clinical success and patency.
