Abstract

Abstract:

Objective

To investigate the clinical efficacy of cutting balloon for treatment of bile duct anastomotic stenosis after liver transplantation (LT).

Methods

Clinical data of 2 patients with bile duct anastomotic stenosis after LT who received treatment of cutting balloon in the Third Affiliated Hospital of Sun Yat-sen University between June 2012 and September 2014 were retrospectively analyzed. The informed consents of the patients were obtained and the local ethical committee approval was received. Case 1 was a 40-year-old male and diagnosed with viral hepatitis C, portal hypertension and postsplenectomy. Case 2 was a 57-year-old male and diagnosed with space-occupying lesion in the liver, virus hepatitis B-induced decompensated liver cirrhosis and type 2 diabetes mellitus. Bile duct anastomotic stenosis after LT was observed in both patients, and was treated by cutting balloon. During the balloon expansion, the inner wall of bile duct was cut by micro-knife blade to enlarge the inner diameter of bile duct and reduce the risk of restenosis. The clinical efficacy of cutting balloon for treatment of bile duct anastomotic stenosis after LT was observed.

Results

No obvious complication was observed in case 1 after cutting balloon treatment. Cholangiography at postoperative 2 months indicated that the anastomotic stenosis was alleviated. The severity of jaundice was alleviated and gradually restored to normal during 3-year follow-up. Slight hemorrhage of the bile duct was observed in case 2 after cutting balloon treatment, and was cured by somatostatin. Cholangiography at postoperative 1 month indicated that the anastomotic stenosis was alleviated and the stent tube was removed. The severity of jaundice was alleviated and gradually restored to normal during 10-month follow-up.

Conclusions

Cutting balloon is a safe and efficacious treatment for bile duct anastomotic stenosis after LT. It can provide a new treatment option for these patients.
