Background
Postoperative cholangitis is one of the major late complications after pancreaticoduodenectomy (PD), and recurrent cholangitis has a negative impact on patients’ quality of life. However, detailed reports are scarce. The aim of this study was to investigate the clinical features of postoperative cholangitis after PD.
Methods
Between January 2007 and December 2013, 155 consecutive patients underwent PD. Of these, 113 patients were included in this study. Cholangitis was diagnosed according to the criteria in the revised Tokyo Guidelines 2013, and repeated cholangitis with three or more episodes was defined as ‘refractory cholangitis’. Data from patients with refractory cholangitis were retrospectively analyzed.
Results
Refractory cholangitis was observed in 21 patients (18.6%). Of these, 17 patients experienced cholangitis within 1 year after PD, and 10 patients had biliary strictures. These patients required an average of two interventional or endoscopic treatments for stricture dilatation, which led to remission. The 2-year cumulative incidence rate for refractory cholangitis was 18.9% (95% CI 11.65–26.15). Multivariate analysis revealed five risk factors for developing refractory cholangitis: benign disease (odds ratio [OR] 18.52; P = 0.001), long operation time (OR 18.73; P = 0.002), elevated C-reactive protein (OR 6.55; P = 0.014), elevated alkaline phosphatase (OR 6.03; P = 0.018), and the presence of pneumobilia (OR 28.81; P = 0.009).
Conclusions
Postoperative refractory cholangitis after PD usually developed within a year. Almost half of the patients had biliary strictures, and aggressive dilatation might be effective to achieve remission in these patients.
