In general, drainage tubes need to be placed in patients with liver abscesses for about 2~3 weeks, but the exact time varies from person to person.
In current clinical practice, after percutaneous hepatic puncture and drainage for patients with liver abscess, generally a single small abscess cavity in a good location needs to be placed in the drainage tube for about 2~3 weeks, and can be removed when the patient’s general condition improves, no pus comes out of the drainage tube, and the rinsing fluid becomes clear, and the pus cavity is significantly reduced.
The placement time of the drainage tube for the poorly located large abscess cavity needs to be extended to more than 4 weeks or even longer. For those who are in poor health and in serious condition, the placement time should be extended accordingly.
In addition, this group of people should also pay attention to a light diet and rest, which is conducive to the recovery of the disease. For more information on how long to leave a puncture drain in a liver abscess, please consult your physician.
