目的对比在乳腺癌保乳术中保留残腔与缝闭残腔的临床疗效。方法将56例乳腺癌保乳手术患者随机分为保留残腔组和缝闭残腔组,每组28例。比较两组术后积液及乳腺外形变化发生率。结果保留残腔组积液及乳房外形一般和差的发生率较缝合残腔组明显升高。结论乳腺癌保乳术后充分游离切口周围腺体后缝闭残腔可明显减少积液的发生率,并有助于提升保留乳房的美容效果。 Objective To compare the clinical efficacy of preserving the residual cavity and closing residual cavity in breast conserving surgery. Methods 56 cases of breast conserving surgery patients were randomly divided into residual group and residual group, 28 cases in each group. The incidences of postoperative effusion and breast shape changes were compared between the two groups. Results The residual rate of residual fluid and the shape of the breast in general and poor were significantly higher than those in the residual suture group. Conclusion Breast conservatism fully free incision around the gland after sewing the residual cavity can significantly reduce the incidence of effusion, and help to enhance the cosmetic effect of breast retention.
