BackgroundSeromas constitute a common complication following surgery for breast cancer, and closed drainage is used routinely to reduce its incidence. The aim of this study was to evaluate the influence of number of drains on patient discomfort, seroma formation, and hospital stay during the immediate postoperative period after mastectomy for breast cancer.Patients And MethodsBased on a retrospective review of our clinical database, 110 consecutive patients from January 2004 through January 2006 who had undergone a mastectomy and axillary clearance for breast cancer were sent a simple postal questionnaire for collection of data.ResultsA total of 70 patients responded (all women; mean age, 69.4 +/- 11.4 years). Twenty-seven patients (38.57%) had 3 drains implanted unilaterally, 24 (34.28%) had 2, and 19 (27.14%) had 1 drain. They were divided into 2 groups: the first group with 1 drain (19 patients) and the other with 2 or 3 drains (51 patients). Median postoperative hospital stay was 2 days (range, 1-8 days); patients with 1 drain had a significantly shorter postoperative hospital stay (median, 2 days [range, 1-4 days] vs. 2 days [range, 1-8 days]; Mann-Whitney U test, P = .02). A total of 15 patients (21.43%) complained of a seroma. There was no difference in seroma rates between groups. Patients who had a single drain implanted had a significantly lower rate of discomfort (median, 2 [range, 1-5] vs. 3 [range, 1-7]; Mann-Whitney U test; P = .04).ConclusionThe number of drains used after a mastectomy for breast cancer did not significantly affect the rate or amount of seromas in this study, but the use of a single drain after mastectomy was significantly associated with less discomfort and shorter postoperative hospital stay.
