The purpose of this study was to compare short-term versus long-term axillary drainage in women treated for lymph node positive breast cancer. A comparative cohort study on differences between short-term or long-term axillary drainage was performed. Primary outcome measures were seroma formation demanding aspiration and wound related complications. ⋯ Short-term axillary drainage does not lead to an increase in wound-related problems, but is associated with a higher incidence of seroma. This seems especially the case in patients who underwent MRM. Therefore, we propose a differentiated policy: patients treated with MRM should be offered long-term axillary drainage, whereas patients treated with breast conserving therapy and ALND or completing ALND after a positive sentinel node should be offered short-term axillary drainage.
