Home Recovery After Mastectomy: Review of Literature and Strategies for Implementation American Society of Breast Surgeons Working Group.

BACKGROUND: Practices regarding recovery after mastectomy vary significantly, including overnight stay versus discharge same day. Expanded use of Enhanced Recovery After Surgery (ERAS) algorithms and the recent COVID pandemic have led to increased number of patients who undergo home recovery after mastectomy (HRAM). METHODS: The Patient Safety Quality Committee of the American Society of Breast Surgeons created a multispecialty working group to review the literature evaluating HRAM after mastectomy with and without implant-based reconstruction. A literature review was performed regarding this topic; the group then developed guidance for patient selection and tools for implementation. RESULTS: Multiple, retrospective series have reported that patients discharged day of mastectomy have similar risk of complications compared with those kept overnight, including risk of hematoma (0-5.1%). Multimodal strategies that improve nausea and analgesia improve likelihood of HRAM. Patients who undergo surgery in ambulatory surgery centers and by high-volume breast surgeons are more likely to be discharged day of surgery. When evaluating unplanned return to care, the only significant factors are African American race and increased comorbidities. CONCLUSIONS: Review of current literature demonstrates that HRAM is a safe option in appropriate patients. Choice of method of recovery should consider patient factors, such as comorbidities and social situation, and requires input from the multidisciplinary team. Preoperative education regarding pain management, drain care, and after-hour access to medical care are crucial components to a successful program. Additional investigation is needed as these programs become more prevalent to assess quality measures such as unplanned return to care, complications, and patient satisfaction.

Pain Control in Breast Surgery: Survey of Current Practice and Recommendations for Optimizing Management-American Society of Breast Surgeons Opioid/Pain Control Workgroup.

INTRODUCTION: The opioid epidemic in the United States is a public health crisis. Breast surgeons are obligated to provide good pain control for their patients after surgery but also must minimize administration of narcotics to prevent a surgical episode of care from becoming a patient's gateway into opioid dependence. METHODS: A survey to ascertain pain management practice patterns after breast surgery was performed. A review of currently available literature that was specific to breast surgery was performed to create recommendations regarding pain management strategies. RESULTS: A total of 609 surgeons completed the survey and demonstrated significant variations in pain management practices, specifically within regards to utilization of regional anesthesia (e.g., nerve blocks), and quantity of prescribed narcotics. There is excellent data to guide the use of local and regional anesthesia. There are, however, fewer studies to guide narcotic recommendations; thus, these recommendations were guided by prevailing practice patterns. CONCLUSIONS: Pain management practices after breast surgery have significant variation and represent an opportunity to improve patient safety and quality of care. Multimodality approaches in conjunction with standardized quantities of narcotics are recommended.

Select Choices in Benign Breast Disease: An Initiative of the American Society of Breast Surgeons for the American Board of Internal Medicine Choosing Wisely® Campaign.

BACKGROUND: Up to 50% of all women encounter benign breast problems. In contrast to breast cancer, high-level evidence is not available to guide treatment. Management is therefore largely based on individual physician experience/training. The American board of internal medicine (ABIM) initiated its Choosing Wisely® campaign to promote conversations between patients and physicians about challenging the use of tests or procedures which may not be necessary. The American society of breast surgeons (ASBrS) Patient safety and quality committee (PSQC) chose to participate in this campaign in regard to the management of benign breast disease. METHODS: The PSQC solicited initial candidate measures. PSQC surgeons represent a wide variety of practices. The resulting measures were ranked by modified Delphi appropriateness methodology in two rounds. The final list was approved by ASBrS and endorsed by the ABIM. RESULTS: The final five measures are as follows. (1) Don't routinely excise areas of pseuodoangiomatous stromal hyperplasia (PASH) of the breast in patients who are not having symptoms from it. (2) Don't routinely surgically excise biopsy-proven fibroadenomas that are < 2 cm. (3) Don't routinely operate for a breast abscess without an initial attempt to percutaneously aspirate. (4) Don't perform screening mammography in asymptomatic patients with normal exams who have less than a 5-years life expectancy. (5) Don't routinely drain nonpainful, fluid-filled cysts. CONCLUSIONS: The ASBrS Choosing Wisely® measures that address benign breast disease management are easily accessible to patients via the internet. Consensus was reached by PSQC regarding these recommendations. These measures provide guidance for shared decision-making.

Endothelial differentiation of adipose-derived stem cells: effects of endothelial cell growth supplement and shear force.

BACKGROUND: Adipose tissue is a readily available source of multipotent adult stem cells for use in tissue engineering/regenerative medicine. Various growth factors have been used to stimulate acquisition of endothelial characteristics by adipose-derived stem cells (ASC). Herein we study the effects of endothelial cell growth supplement (ECGS) and physiological shear force on the differentiation of ASC into endothelial cells. MATERIALS AND METHODS: Human ASC (CD13(+)29(+)90(+)31(-)45(-)) were isolated from periumbilical fat, cultured in ECGS media (for up to 3 wk), and exposed to physiological shear force (12 dynes for up to 8 d) in vitro. Endothelial phenotype was defined by cord formation on Matrigel, acetylated-low density lipoprotein (acLDL) uptake, and expression of nitric oxide synthase (eNOS), von Willebrand factor (vWF), and CD31 (platelet endothelial cell adhesion molecule, PECAM). Additionally, cell thrombogenicity was evaluated by seeding canine autologous ASC onto vascular grafts implanted within the canine arterial circulation for 2 wk. RESULTS: We found that undifferentiated ASC did not display any of the noted endothelial characteristics. After culture in ECGS, ASC formed cords in Matrigel but failed to take up acLDL or express the molecular markers. Subsequent exposure to shear resulted in stem cell realignment, acLDL uptake, and expression of CD31; eNOS and vWF expression was still not observed. Grafts seeded with cells grown in ECGS (+/- shear) remained patent (six of seven) at 2 wk but had a thin coat of fibrin along the luminal surfaces. CONCLUSIONS: This study suggests that (1) ECGS and shear promote the expression of several endothelial characteristics in human adipose-derived stem cells, but not eNOS or vWF; (2) their combined effects appear synergistic; and (3) stem cells differentiated in ECGS appear mildly thrombogenic in vitro, possibly related, in part, to insufficient eNOS expression. Thus, while the acquisition of several endothelial characteristics by adult stem cells derived from adipose tissue suggests these cells are a viable source of autologous cells for cardiovascular regeneration, further stimulation/modifications are necessary prior to using them as a true endothelial cell replacement.
