Mastectomia radical modificada com drenagem por sucção contínua versus sem drenagem

Abstract

This research was conducted in order to analyze the results of seroma formation after modified radical mastectomy using suction drain versus no suction drain with a wound closure tecnique. This prospective study included seventy-two (72) patients who had operable breast cancer. All patients underwent modified radical mastectomy (Madden surgery) followed by wound closure using inabsorvent stitch between the skin and the chest wall musculature. The axila was also closed and the suction drains were placed beneath the skin and in the axila. The drains were removed 24 hours after surgery. Of the seventy-two (72) patients in the study, thirty-seven underwent the surgery and had drains placed. Thirty-five patients had no drains place following surgery. Evaluations factors included: age, weigth, clinical stage, number of axillary lymph nodes removed and positive lymph nodes. Complications (thus are of study) in both groups of patients included: seroma, infected seroma, skin necroses, hematoma and wound infection. The results of these seventy-two patients showed no significant statistical difference between the two groups in relation to: age (p=0.59), weight (p=0.25), height (p=0.83), clinical stage (p=0.44), lymph nodes removed (p=0.63) and positive lymph nodes (p=0.94). Surgical complications occurred in 10 patients (27%) in the first group (with drains) and in 12 patients (34,3%) in group two (without drains). Seroma formation was present in 8 patients in group 1 (21,6%) and in 10 patients in group 2 (28,6%). No significant statistical difference was noted between the two groups in relationship to the total number of complications (p=0.50) and seroma (p=0.49). The author concluded that modified radical mastectomy (associated with wound closure) and without drains can be safely performed without increasing surgical complications
