Drainage or suture of the cavity after breast biopsy.
An initial series of 105 women who underwent excision biopsy of the breast were entered into a controlled randomised trial to determine the effect on postoperative morbidity of drainage of the cavity with a soft rubber Penrose drain. The use of this drain had no effect on the incidence of postoperative wound complications (drain 11 of 40 (28%), no drain 10 of 58 (17%]. A second series of 202 women were entered into a randomised controlled trial to determine the effect of closed suction drainage and suture of the cavity after breast biopsy. The use of this drain significantly reduced the incidence of postoperative wound complications (drain 9 of 93 (10%), no drain 22 of 105 (21%], but although suture of the cavity halved the number of wound complications (suture 11 of 97 (11%), no suture 20 of 101 (20%], this did not reach statistical significance. Wound complications were more frequent with large wounds (28%) than with smaller ones (15%), and with less experienced operators (registrar 21%, senior registrar/consultant 10%). We conclude that a closed suction drain will reduce the incidence of wound haematomas after breast biopsy but that a Penrose drain is ineffective in the prevention of wound complications.
