Biliodigestive Anastomosis in Liver Transplantation: Review of 13 Years

Considerable Risk of Restenosis After Endoscopic Treatment for Hepaticojejunostomy Stricture After Living-Donor Liver Transplantation

BACKGROUND

There are few reports on the short- and long-term follow-up of endoscopic retrograde cholangiography (ERC) in adult patients with hepaticojejunostomy (HJS) stricture after living-donor liver transplantation (LDLT).

METHODS

Nine LDLT recipients underwent ERC with the use of double-balloon endoscopy (DBE) for HJS stricture at Nagoya University Hospital. We assessed the rate of reaching biliary anastomosis, procedure success rate, procedure duration, complications, improvement in liver function test results, and biliary anastomosis patency.

RESULTS

In total, 19 ERC procedures with the use of DBE were performed for 9 adult LDLT recipients with HJS stricture from June 2006 to September 2014. Balloon dilation with the use of DBE was successfully performed in 5 of the 9 patients during the 1st procedure. Of the 4 patients in whom DBE-ERC failed to be completed, 3 patients underwent 2nd procedures successfully. Liver function test results were significantly improved in the successful cases. Four patients underwent 2nd DBE-ERC for stricture recurrence at a mean time of 2.3 years after the 1st successful procedure. Of those, 2 patients required 3rd procedures for stricture recurrence after the 2nd procedure.

CONCLUSIONS

DBE-ERC is promising as a treatment for HJS stricture in adult LDLT recipients in the short term. However, the DBE-ERC procedure may have a considerable risk of restenosis.

Hepaticojejunostomy with the "Hand-Fan" technique

A standard hepaticojejunostomy technique might be difficult to perform, especially when the bile duct is small and located deep in the liver hilum. Herein we present a new procedure, the Hand-Fan technique, that was used to enhance the exposure and ease the performance of these challenging anastomoses. Thirty-one patients who had had hepaticojejunostomy with this technique for bile duct injury and other benign biliary pathologies from July 2004 to June 2011 were included into the study. Median postoperative hospital stay was 7 days (6-25 days) and median follow-up time was 33 months (2-84 months). Liver function tests revealed that the blood bilirubin levels of the patients were normalized after hepaticojejunostomy. Follow-up showed that there were no signs of clinical recurrence or impaired bile flow. The Hand-Fan technique considerably facilitates challenging hepaticojejunostomies. Surgeon's comfort is exceptional and the clinical results are satisfactory.
