BACKGROUND/AIMS: To study and review the clinical manifestations, microbiology, comorbidity, and diagnosis of @entity5572 for malignant @entity99 . METHODOLOGY: We retrospectively reviewed 1374 @entity1 who underwent 2581 transarterial chemoembolization procedures due to malignant @entity99 over an 8-year period. RESULTS: 7 @entity1 had @entity5572 . The incidence was 0.27% (7/2581). @entity157 was diagnosed in all 7 @entity1 , whose liver function was classified as stage A by the @entity1 -Pugh criteria. The clinical manifestations were intermittent fever, @entity490 , and leukocystosis. All the @entity1 had @entity1867 with reverberative shadows on sonograms or low attenuation areas with different Hounsfield units on computed tomography scan, which expressed the 100% incidence (7 of 7) of gas-forming abscesses. Percutaneous drainage or aspiration was done in 6 @entity1 . One received laparotomy with local debridement due to suspicious organ rupture. The pus culture showed Gram-negative bacteria in all @entity1 . Blood cultures were positive in only 3 of 7 @entity1 (43%). No @entity1 died of @entity5572 after aspiration, drainage, or debridement of abscess combined with parenteral antibiotic treatment. @entity253 , found in 4 @entity1 , were the most common comorbidity. CONCLUSIONS: @entity5572 after transarterial chemoembolization is a very rare complication, which usually develops in @entity1 with @entity253 . Gram-negative bacteria are the main pathogens. The incidence of gas formation is higher after transarterial chemoembolization than in the general population. However, the prognosis is good after adequate clearance of pus and antibiotic treatment.
