A quilting sutures technique for flap closure in patients undergoing modified radical mastectomy for the prevention of seroma: A single-center, randomized controlled trial

Seroma formation is a common adverse event following modified radical mastectomy, and it leads to delayed wound healing and increased post-operative pain and increases overall morbidity of patients. The quilting sutures as a newer technique for the skin flap closure is done to reduce incidence of seroma formation. Although it has controversy in the literature for the satisfactory outcome, the study has aimed to compare the Quilting suture technique with the conventional closure method to evaluate the efficacy of the quilting technique. The primary objective of the study was to access and compare the frequency of seroma formation following the quilting suture technique with standard flap closure in MRM. The secondary objectives were to compare drain output, post-operative complications, and the requirement of additional procedures for management of related complications. The 72 female participants in this randomized control trial had modified radical mastectomy after being diagnosed with breast cancer. The quilting suture technique was applied in the 36 patients and conventional technique applied in 36 patients for skin flap closure. The frequency of seroma formation and other complications were reported. Between the two groups, there was no statistically significant difference in the frequency of seroma production (P = 0.233). Total drainage volume (P = 0.213), drainage duration (P = 0.652), and post-operative complications (P = 0.641) did not substantially differ between the two groups. The study concludes that the quilting sutures technique does not decrease the incidence of seroma formation, total drain output, and total duration of drainage. There is no significant difference in complications and requirement of additional procedures compared to the standard technique.
