Background and aims: Pylephlebitis (septic thrombophlebitis of the portal venous system) is a rare complication of intra-abdominal infection. We aimed to investigate the recent trend of its etiology, clinical manifestation, and prognosis. Methods: We retrospectively studied the etiology, clinical manifestation, and outcome by reviewing the medical records of all imaging-confirmed pylephlebitis cases diagnosed during the period 2002-2011 in a university hospital in Taiwan. To identify the risk factors for pylephlebitis, we randomly selected 160 patients with intra-abdominal infections but without pylephlebitis as the comparison group. Results: We identified 35 cases of pylephlebitis. Most patients were men [29/35 (83 %)]. The median age of the patients was 57 years (range 35-90 years). Unspecified abdominal pain (18/35) and fever (10/35) were the most common clinical manifestations. Klebsiella pneumoniae liver abscess (7/35) and cholangitis (7/35) were the most common etiologies. Liver abscess was a risk factor for pylephlebitis (13/35 vs. 27/160, P = 0.01). With antibiotic therapy, there was no in-hospital mortality, but pylephlebitis was still associated with an excess hospital stay (22.2 ± 17.6 vs. 9.8 ± 7.1 days, P < 0.001). Conclusions: Our study results suggested a different pattern of pylephlebitis from previous Western literature. K. pneumoniae liver abscess (7/35) is an emerging etiology of pylephlebitis in Taiwan.
