Abstract
Background
Distinguishing malignant from benign causes of obstruction at the liver hilum can pose a diagnostic dilemma. This study aimed to determine factors that predict benign causes of hilar obstruction and long-term outcomes after resection.
Methods
Consecutive patients who underwent surgery for hilar obstruction at a single institution between 1997 and 2022 were retrospectively analyzed. Median follow-up was 26 months (range 0–281 months).
Results
Among 182 patients who underwent surgery for hilar obstruction, 25 (14%) patients were found to have benign disease. Median CA19-9 level after normalization of serum bilirubin was 80 U/mL (range 1–5779) and 21 U/mL (range 1–681) among patients with malignant and benign strictures, respectively (p = 0.001). Cross-sectional imaging features associated with malignancy were lobar atrophy, soft tissue mass/infiltration, and vascular involvement (all p < 0.05). Factors not correlated with malignancy were jaundice upon presentation, peak serum bilirubin, sex, and race. Preoperative bile duct brushing or biopsy had sensitivity and specificity rates of 82% and 55%, respectively. Among patients who underwent resection with curative intent, grade 3–4 complications occurred in 55% and 29% of patients with malignant and benign strictures, respectively (p = 0.028). Postoperative long-term complications of chronic portal hypertension and recurrent cholangitis occurred in ≥ 10% of patients with both benign and malignant disease (p = non-significant).
Conclusions
Strictures at the liver hilum continue to present diagnostic and management challenges. Postoperative complications and long-term sequelae of portal hypertension and recurrent cholangitis develop in a significant number of patients after resection of both benign and malignant strictures.
