Infected intraabdominal hematomas: percutaneous drainage

Percutaneous drainage of infected intraabdominal hematomas has often been contraindicated due to its greater number of complications. The results of percutaneous drainage of infected localized hematomas in five cases are described, two in the lesser sac and three in the right subphrenic space. The catheter size ranged from 8.4 to 24 French. Mean maintenance time of the drainage was 37 days. Drainage tube obstruction occurred in three patients, in two of whom the drainage tube had to be changed for one with a broader gauge. Hematomas were completely resolved in all the cases. We describe our experience with one patient in whom we used intracavitary urokinase who showed successful results. Percutaneous drainage is not contraindicated in the management of infected hematomas, although the drainage tube must be closely controlled; drainage time may be longer than in other types of abscesses.
