Surgical reconstruction of major bile duct injuries: Long-term results and risk factors for restenosis.

BACKGROUND

A single-institution retrospective analysis was undertaken to assess long-term results of definitive surgical reconstruction for major bile duct injuries and risk factors for restenosis.

METHODS

Patients treated between January 1995 and October 2020 were reviewed retrospectively. The primary outcome measure was patency.

RESULTS

Of 417 patients referred to a tertiary center, 290 (69.5%) underwent surgical reconstruction; mostly in the form of a hepaticojejunostomy (n = 281, 96.8%). Major liver resection was undertaken in 18 patients (6.2%). There were 7 postoperative deaths (2.4%). Patency was achieved in 97.4% of primary repairs and 88.8% of re-repairs. Primary patency at three months (including postoperative deaths and stents removed afterwards) in primary repairs was significantly higher than secondary patency attained during the same period in re-repairs (89.3% vs 76.5%, p < 0.01). The actuarial primary patency was also significantly higher compared to the actuarial secondary patency 10 years after reconstruction (86.7% vs 70.4%, p = 0.001). Vascular disruption was the only independent predictor of loss of patency after reconstruction (OR 7.09, 95% CI 3.45-14.49, p < 0.001), showing interaction with injuries at or above the biliary bifurcation (OR 9.52, 95% CI 2.56-33.33, p < 0.001).

CONCLUSIONS

Long-term outcome of surgical reconstruction for major bile duct injuries was superior in primary repairs compared to re-repairs. Concomitant vascular injury was independently associated with loss of patency requiring revision.
