What Causes Frequent Perirectal Abscess?

I have an 9 year old son who is having recurrent perirectal abscesses. He has had one i&d with hospitalization and vancomycin. He is now on his fourth one in four months and his fifth round of bactrim. The doctor did second culture because first showed nothing.

Hello, thank you for posting your query here. Recurrent perirectal abscesses could be due to colonisation with a bacteria called staph aureus in his body, which may be a resistant strain.
After the current abscess settles, I suggest you do a decolonisation with mupirocin ointment applied in both his nostrils twice a day for 5 days, with chlorhexidine body washes for 10 days. Give special attention to scrubbing his armpits and groin are well as the bacteria thrives in these areas.
if he has had frequent abscesses in the past also, he should get evaluated for immunodeficiency as well/
Hope this helps you, take care.
Regards,
Dr. Vaishnavi
