[Feasibility and accuracy of day surgery: Review of 396 operated breast cancer patients]. / La chirurgie du cancer du sein en ambulatoire est faisable et fiable de nos jours : étude portant sur 396 patientes.

ABSTRACT

INTRODUCTION: Breast cancer surgery is suitable for outpatient practice. Indeed, this is a planned surgery with short operative time. Objective was to evaluate the recognized success indicators in day surgery rate of conversion into conventional hospitalization, rate of complications and re-hospitalizations the month following surgery. METHODS: Consecutive cases of breast cancer patients operated in day surgery were prospectively entered into the Day Surgery database between 25 November 2012 and 31 December 2013. Patient characteristics and tumor pathology, preoperative procedures and type of surgery were collected. Statistical analysis was performed. RESULTS: Three hundred and ninety-six consecutive patients were included. The mean age was 54 years [25-84], we performed 382 conservative breast surgery (98.2%), 238 sentinel node (60.1%) and 40 axillary lymphadenectomy (10.1%). Thirty-nine scheduled for outpatient surgery were hospitalized in conventional surgery being a conversion rate of 9.8%, 95% CI [6.9-12.7] with 24 patients because of a drainage (61.5%). We have observed 15 complications in the month after the surgery (3.7%, 95% CI [1.8-5.6]), and 5 rehospitalization in the month following surgery (1.2%, IC 95% [0.1-2.3]). CONCLUSION: Postoperative complication and readmissions are very low (<5%) after breast ambulatory surgery. This confirms its feasibility and safety in a breast cancer center. Adaptating anaesthetic methods to ambulatory care and preparing patient going home with an axillary drain are necessary to reduce rate of conversion to hospitalisation.
