Abstract
BackgroundThe aim of this study was to compare conventional suture with prolonged timing of drainage with quilting suture on the formation of seroma at pectoral area after mastectomy (ME) with sentinel lymph node biopsy (SLN) or axillary lymph node dissection (ALND) for breast cancer.MethodsThree hundred and eighty-eight consecutive breast cancer patients were retrospectively analyzed and categorized into three groups. Patients in group 1 were with quilting suture, group 2 with conventional suture and 13–15 days drainage in situ, and group 3 with conventional suture and 20–22 days drainage. The primary outcome was the incidence of grades 2 and 3 seroma at anterior pectoral area within 1 month postoperatively. Cox regression was used for analysis.ResultsThe incidence of grades 2 and 3 seroma was comparable among groups (9.5% vs. 7.9% vs. 5.3%, p = 0.437), as well as late grades 2 and 3 seroma among groups (4.3% vs. 2.9% vs. 1.5%, p = 0.412). Old age, high body mass index, and hypertension were independent risk factors for grades 2 and 3 seroma.ConclusionsProlonged timing of drainage to 13–15 days in conventional suture was long enough to decrease the incidence of grades 2 and 3 seroma as lower as that in quilting suture group at pectoral area within 1 month after mastectomy.
Highlights
The aim of this study was to compare conventional suture with prolonged timing of drainage with quilting suture on the formation of seroma at pectoral area after mastectomy (ME) with sentinel lymph node biopsy (SLN) or axillary lymph node dissection (ALND) for breast cancer
In our previous retrospective study, we focus on the seroma in the dead space at the pectoral area [12]
We showed that quilting suture applied at medial and inferior border of the dead space at the pectoral area could reduce the incidence of grades 2 and 3 seroma compared with the conventional suture
Summary
The aim of this study was to compare conventional suture with prolonged timing of drainage with quilting suture on the formation of seroma at pectoral area after mastectomy (ME) with sentinel lymph node biopsy (SLN) or axillary lymph node dissection (ALND) for breast cancer. In our previous retrospective study, we focus on the seroma in the dead space at the pectoral area [12]. We showed that quilting suture applied at medial and inferior border of the dead space at the pectoral area could reduce the incidence of grades 2 and 3 seroma compared with the conventional suture. In order to lower the incidence of late grades 2 and 3 seroma, we tried to prolong the time of drainage and explore the best time point of drainage removal in this study
