The extended latissimus dorsi flap has been widely used for breast reconstruction. However, seroma at the donor site is a common complication and makes it difficult for reconstructive surgeons to choose it as a primary option. We analyzed the association between seroma and reconstructions with extended latissimus dorsi flaps. A series of 120 consecutive cases were included in this study. The average body mass index (BMI) was 22.1 kg/m2, and the mean ratio of the flap weight to the extirpated breast weight was equivalent to 101.6%. The mean age of patients was 40.3 years. Donor-site seroma was reported in 69.2% (83 cases) of the total patients. With respect to BMI, flap weight, and age, the incidence and duration of donor-site seroma showed statistically significant differences (P < 0.05). Both the incidence and duration of seroma were significantly higher and longer in patients who had high BMI (>23 kg/m2), large flap (>450 g) for reconstructions, or advanced age (>45 y). In these cases, greater attention and additional adjunctive procedures would be needed to prevent seroma.
