Abstract: ［Abstract］ Objective To determine whether there was a difference in complications among breast cancer patients undergoing day?surgery versus overnight or inpatient stay. Methods 108 patients with breast cancer undergoing mastectomy and axillary lymph node dissection between Dec 2016 and Feb 2019 were included in this study. Among them， 24 cased underwent daytime surgery （day?surgery group）， 32 stayed in hospital overnight （overnight group） and 52 stayed in hospital longer than 2 day postoperatively （normal group）. The clinical data were analyzed and compared between three groups. Results The operation time of the three groups was close， and the use of analgesics in the day?surgery group was more than that in the other two groups， but the differences were not statistically significant. The number of community medical and outpatient visits increased in the day?surgery group after leaving hospital， and there was a significant difference between the two groups after more than two days of admission. The total medical expenses in the daytime operation group were significantly lower than those in the other two groups. There was no significant difference in incision bleeding， hematoma， surgical site infection and pain among the three groups. Conclusion Day? surgery of breast cancer with less cost， no severe complications occurred in outpatients， can be safely and comfortably performed on an outpatient basis.

摘要： ［摘要］ 目的 探讨乳腺癌患者日间手术的优势及与住院患者并发症的差异。方法 选择2016年12月至2019年2月期间，108名乳腺癌患者接受乳房切除术和腋窝淋巴结清扫。其中24例接受日间手术（日间手术组），32例住院过夜（过夜手术组），52例术后住院时间超过2天（正常组）。分析比较三组患者的临床资料进行。结果 三组患者的手术时间接近，日间手术组镇痛剂使用量大于其他两组，但差异无统计学意义。出院后日间手术组的社区医疗和门诊就诊次数有所增加，两组与入院两天以上组患者比较，差异有统计学意义；日间手术组的总医疗费用明显低于其他两组；三组在切口出血、血肿、手术部位感染、疼痛等方面无显著性差异。结论 门诊乳腺癌日手术费用低，无严重并发症，可安全、舒适地进行。
