ObjectivesThe aim of this study is to compare efficacy of loop drainage and standard incision & drainage (I&D) in adult patients with cutaneous abscess in the emergency department.MethodsThis study is an interventional, parallel group, randomized clinical trial. Adult patients with cutaneous abscess were randomized into loop drainage and standard I&D groups. The primary outcome was defined as change in diameter of abscess and cellulitis 7days after procedure. Secondary outcome measures were pain intensity at the end of the procedure and procedure duration. Also patient satisfaction, need for antibiotics and repetitive drainage were recorded.ResultsA total of 46 patients were included in the study (23 in each group). Both groups had similar baseline characteristics. Median abscess diameters were 3.2 (1.9-4.0) cm and 3.0 (2.4-4.8) cm in loop drainage and I&D groups respectively. In the loop drainage group there was a -0.6cm (95% CI: -1.7-0.5) difference in abscess diameter compared to the I&D group. There was also a reduction in cellulitis diameter (-1.3cm, 95% CI: -3.4-0.8). No statistically significant difference was found between groups in patient satisfaction, use of antibiotics or need for repetitive drainage.ConclusionThis preliminary study revealed that, loop drainage technique is similar to standard I&D technique in abscess resolution and complications.
