title: [Frequency of postoperative seromas in mastectomy wounds with the use of one or two drainages: a pilot study].
abstract: OBJECTIVE
  To compare the number of postoperative seromas after mastectomy with the use of one or two drainages.
  
  
  METHODS
  Women with malignant tumors who underwent Madden modified radical mastectomy were studied. They were divided into two groups: group A two drainages (axillar and pectoral), group B only one (axillar). For both groups demographical issues, body mass index (BMI = kg/m2), seromas and drainage period were determined.
  
  
  RESULTS
  Twenty seven patients were evaluated: group A composed of 12 patients and B composed of 15. Age (years): A 56 +/- 14 vs B 50 +/- 6.5 (p NS), BMI: A 33.2 +/- 3.4 vs B 32.6 +/- 4.5 (p NS); seromas: A 4 vs B 5 (p NS); drainage period: A 23 +/- 6 vs B 24 +/- 7 (p NS).
  
  
  CONCLUSIONS
  There are no differences in postoperative seroma development in mastectomy wounds with the use of one or two drainages.
