Incision and drainage of cutaneous abscess with or without cavity packing: a systematic review, meta-analysis, and trial sequential analysis of randomised controlled trials.

Incision and drainage of cutaneous abscess with or without packing have comparable outcomes. However, considering the cost and post-operative pain associated with packing, performing the procedure without packing of the abscess cavity may be more favourable. The findings of the better quality ongoing RCTs may provide stronger evidence in favour of packing or non-packing.
