Hypothesis:
Biliary reconstruction of the small bile duct is difficult, and bilioenteric reconstruction without mucosa-to-mucosa alignment would be a simple and useful maneuver in this situation; however, the long-term results of this surgical technique remain to be evaluated.
Objective:
To evaluate the usefulness of bilioenteric reconstruction without mucosa-to-mucosa alignment from the standpoint of the long-term results.
Design:
Retrospective review.
Setting:
University hospital.
Patients:
Bilioenteric reconstruction without mucosa-to-mucosa alignment was performed in 17 patients at our institution. Six patients had malignancy, and 11 were liver transplant recipients from a living donor.
Main Outcome Measures:
Clinical records, blood chemistry data, and findings from dynamic computed tomography.
Results:
Among the 17 patients, 4 died of recurrent malignant disease, and 3 died of thrombosis, brain hemorrhage, and pneumonia, respectively. During the follow-up (median, 41.2 months) of the remaining 10 patients, cholangitis occurred in 2 (1 episode in each), and anastomotic leakage from the hepaticojejunostomy performed by the standard method for other thicker ducts developed in 1. There were no other anastomosis-related complications. Dynamic computed tomography performed 2.4 to 62.7 months (median, 34.4 months) after the operation showed no bile duct dilatation in any of the 10 cases.
Conclusions:
Long-term patency of the small bile ducts after bilioenteric reconstruction without mucosa-to-mucosa alignment was demonstrated. Thus, this technique is useful for the reconstruction of small bile ducts, especially in patients with poor liver function in whom even minimal additional reduction in the volume of functioning liver due to occlusion of a small bile duct would be acceptable.
