title: [Analysis of percutaneous hepatic abscess drainage with an emphasis on factors influencing clinical outcome].
abstract: A retrospective review of 52 patients who underwent percutaneous abscess drainage (PAD) of liver abscesses was carried out. Several kinds of bacteria were isolated from the pus in 31 of 52 cases. There were four cases of amebic liver abscess. Correlations with the shape, number, size, ascites, biliary communication, and underlying status of patients were investigated. Rates of cure, palliation, and failure were 59.6% (31 of 52 patients), 32.7% (17 of 52 patients), and 7.7% (4 of 52 patients), respectively. The cure/palliation rates in patients with malignancy or biliary diseases were significantly lower than those in patients without malignancy or biliary diseases (n = 48, p < .01). There was no statistically significant difference in the cure/palliation rate according to the shape or size of the liver abscess. Twelve patients of 52 (23.0%) died during drainage, because they were critically ill. Massive bleeding (s> 500 ml) as the major complication was seen in three (5.8%). Recurrence was noted in five (9.6%), four of whom were associated with biliary diseases. The author stresses that PAD is an effective therapeutic adjunct for any kind of liver abscess.
