Abstract

Background: To assess the outcome of patients with biliary atresia (BA) who underwent a surgical shunt (SS) for severe portal hypertension (PH) following a Kasai procedure.

Methods: We collected and analyzed the data and outcomes of patients with BA who underwent SS for severe PH following a Kasai procedure between 1974 and 2014, focusing on complications related to the procedure, overall survival (OS), and transplant-free survival (TFS).

Results: SS was performed at a median age of 5.5 years [2-13.5] in 38 patients. Conjugated bilirubin level (cBL) was ≤20 μmol/l in 24 patients at time of SS. Median follow-up was 15 years [1-32]. OS at 5 and 10 years was 91% and 87% respectively. TFS at 5 and 10 years was 84% and 70% respectively. Long-term complications included hepatic encephalopathy in 9 patients, and hepatopulmonary syndrome in 3. At last follow-up, 10/14 patients without LT and 18/ 24 who had a delayed LT at a median delay of 11 years [1.5-22] were alive.

Conclusion: Surgical shunt for severe portal hypertension in biliary atresia may delay the need for liver transplantation. However complications are indications for transplantation.

Level of evidence: Type of study: Therapeutic. Level of evidence III.

Keywords: Biliary atresia; Kasai; Portal hypertension; Portosystemic shunt.
