Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The investigators propose to conduct a, two armed, randomized, controlled pilot study to assess the clinical effects of a) open incision, drainage with daily packing changes, compared to b) Ultrasound guided needle aspiration, in drainage of uncomplicated cutaneous abscesses below the skin surface of adult emergency department patients using concealed allocation in evaluating patient satisfaction.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Exclusion Criteria

* Patients under the age of 18 years,
* Patients with a Glasgow coma scale score of \<15 (i.e. not completely alert and oriented),
* Patients suspected of having necrotising fascitis,
* Patients with hemodynamic instability (defined as SBP \<90, and/or HR \>110),
* Patients admitted to hospital,
* Patients who are neither French nor English speaking,
* Patients who are not available for telephone follow-up (i.e. homeless).
* Ultrasound image demonstrates that the abscess is not compressible (generally indicates that the contents of the cyst includes solids, which would not be amenable to aspiration)
* Ultrasound demonstrates that there is no abscess to manage,
* Patients with perianal abscesses who have either Crohn's disease or ulcerative colitis or known perirectal fistula,
* Patients with recurrent abscesses in the same location or abscesses present for more than 2 weeks
* Patients with complex abscesses including deep tissue, sensitive body part involvement which includes: ears, eyes, lacrimal, orbital, submandibular, mouth, peritonsillar, and Bartholin's gland.
* Patients with renal impairment, diabetes, immunocompromised (as these patients are at risk of becoming more ill if an abscess were able to grow).
