Effects of minimally invasive breast resection on nonpalpable breast nodules / 中国综合临床

ABSTRACT

Objective To compare the efficacy of ATEC system and conventional surgery for the treatment of nonpalpable breast nodules.Methods Two hundred and forty cases patients with nonpalpable breast nodules who were treated in Maternal and Child Health Hospital of Pinggu District of Beijing from September 2014 to June 2016 were admitted and randomly divided into observation group and control group,120 cases in each group.The observation group was treated with minimally invasive treatment,while the control group was treated by conventional surgery.The postoperative pathologic results,surgical parameters and complications were compared between 2 groups.Results One hundred and eighteen cases were successfully removed and 210 pathological specimens were obtained in the observation group,including 201 benign lesions in 112 cases and 9 malignant lesions in 6 cases.In the control group,208 benign lesions in 113 cases and 11 malignant lesions in 7 cases were obtained from 120 cases.There was no significant difference in the proportion or type of pathology between 2 groups(P＞0.05).The operative time,blood loss,scar length and wound healing time were all significantly lower in the observation group than those in the control group((16.72±3.65)min vs.(41.21±5.94)min,(9.45±2.35)ml vs.(28.42±7.30)ml,(3.64±0.85)mm vs.(28.51±6.34)mm,(3.36±0.67)d vs.(6.79±1.58)d;t=38.245,26.891,42.238,21.738;P＜0.001).The incidence of breast collapse or deformity in the observation group was lower than that in the control group(0 vs.6.7％,P=0.007),but there was no significant difference in the incidence of hematoma,skin ecchymosis,local infection or nodular recurrence between 2 groups(P＞0.05).Conclusion Breast minimally invasive resection is effective in the treatment of nonpalpable breast nodules,and is suitable for patients with high demands on breast appearance.
