- W1620199320 abstract "Background/Aims: Hepatolithiasis is a well known risk factor of cholangiocarcinoma. Despite advances in diagnostic modalities, diagnosing cholangiocarcinoma in patients with hepatolithiasis still challenging and there are not enough reports on the incidence of cholangiocarcinoma in patient with hepatolithiasis after treatment. We aimed to evaluate the incidence and clinical characteristics of cholangiocarcinoma in patients with hepatolithiasis who underwent liver resection or non-resection. Methods: Among a total of 257 patients who received treatment for hepatolithiasis from 2002 to 2011 at Korea University Anam and Guro Hospital, 236 patients were eligible for analysis; 92 patients underwent liver resection (resection group) and 144 patients did not (non-resection group). The data were retrospectively collected and analyzed. Results: The incidence of cholangiocarcinoma was 6.8% (16/236) during follow-up period (mean 41±41 months). The median tumor occurrence time was 28 (13-111) months. Cholangiocarcinoma occurred 6.5% (6/92) and 6.9% (10/144) in resection and non-resection group respectively (P=0.425). In resection group, cholangiocarcinoma occurred in 3.6% (2/56) of patients with complete stone removal, and in 13.3% (4/ 30) of patients with incomplete stone removal (p=0.591). In non-resection group, cholangiocarcinoma occurred in 5.7% (3/53) of patients with complete stone removal, and in 8.9% (7/79) of patient with incomplete stone removal (p=0.738). When analyzed according to completeness of stone removal regardless of treatment modality, cholangiocarcinoma occurred in 4.6% (5/109) of patients with complete stone removal, and in 10.1% (11/109) of patients with incomplete stone removal (p=0.429). Although the site of stone and tumor occurrence concurred in 10/16 patients (3/6 patients in the resection group, 7/10 patient in the non-resection group), it did not match in 6 patients. On univariate analysis, none of the factors (age, gender, abdominal pain, bile duct stenosis, bile duct dilatation, liver atrophy, residual stone, stone recurrence and liver resection) showed relationship with the incidence of cholangiocarcinoma. Conclusion: There was no difference in the incidence of cholangiocarcinoma according to the treatment modality or completeness of stone removal. Therefore, patients with hepatolithiasis should carefully be followed-up to detect cholangiocarcinoma even after treatment." @default.
