Abstract
Background
Abdominal flaps and latissimus dorsi flaps can be used to provide soft tissue coverage and recreate the breast mound following breast conservation therapy (BCT), which consists of lumpectomy and radiation. This study compares complication rates and the need for revision surgery between the two flap groups.
Methods
This study retrospectively reviewed charts for all patients who underwent BCT and presented for delayed partial breast reconstruction with either a free abdominal flap (MS-TRAM, DIEP, SIEA) or pedicled latissimus dorsi flap at our institution between January 2005 and August 2017. Charts were reviewed for basic demographics, comorbidities, oncologic data, postoperative complication incidence, and whether patients underwent revisionary surgery.
Results
A total of 21 patients met inclusion criteria, which included 12 latissimus (LD) and 9 abdominal (Abd) flap-based reconstructions. Demographics and comorbidities were similar between cohorts. Overall complication rates were similar between groups for both recipient site (LD: 16.7%, Abd: 22.2%; p = 0.748) and donor site (LD: 8.3%, Abd: 0.0%; p = 0.375). Overall rates of revisionary surgery were also similar in both groups (p = 0.445). Mean follow-up time was similar between the two cohorts (p = 0.227).
Conclusions
The flap choice in partial reconstruction is multi-factorial and is based largely upon surgeon experience, surgeon and patient preference, and body habitus. Our study shows that both abdominal flaps and the latissimus dorsi flap are able to reconstruct partial mastectomy defects with relatively low and comparable complication rates. Revision rates are similar between the autologous flap options as well.
Level of evidence: Level IV, Therapeutic.
