RESUMO
The aim of this study was to compare quilting suture with axillary drain versus conventional sutures with axillary and pectoral drain on the formation of seroma after modified radical mastectomy with axillary lymph node dissection. The study was undertaken among 90 female patients with breast cancer who were candidates for modified radical mastectomy with axillary clearance. The intervention group (N = 43) with quilting and axillary drain placement and the control group (N = 33) without quilting with axillary and pectoral drain placement. All the patients were followed up for complications pertaining to this procedure. There were no significant differences between the two groups with regard to demographic characteristics, comorbidities, pre-operative chemotherapy, post-operative pathological findings, lymph node involvement or clinical staging. The incidence of seroma formation on follow-up was significantly lower in the intervention group than that in the control group (23% versus 58%; p < 0.05) whereas there was no significant difference with respect to flap necrosis, superficial skin necrosis and wound gaping between the two groups. Furthermore, it took a shorter duration for seroma to resolve in the intervention group (4 days versus 9 days; p < 0.001) with a smaller duration of hospital stay (4 days versus 9 days; p < 0.001). The use of quilting sutures for flap fixation in order to obliterate dead space post-modified radical mastectomy with placement of axillary drain significantly reduced seroma formation along with shorter duration of wound drainage and a smaller hospital stay with only slightly increased operative time. Therefore, we recommend quilting of flap as a routine step after mastectomy.
