How to Start and Build a Practice in Microsurgical Breast Reconstruction: Success and Sustainability in a Private Practice Setting.

The aim of this article is to provide a template for building and sustaining a microsurgical breast reconstruction practice in a private practice setting. The target audience including residents, microsurgical fellows, and reconstructive microsurgeons were currently employed in an academic setting, and reconstructive microsurgeons were currently employed in a private group entity. We present five pillars that initiate, support, and sustain a successful practice in microsurgical breast reconstruction. The five key concepts are (1) establishing a practice vision and culture, (2) obtaining funding, (3) assembling staff, (4) negotiating insurance and other contracts, and (5) striving for efficiency and sustainability. These concepts have been at the core of Plastic, Reconstructive and Microsurgical Associates of South Texas-a private practice eight-physician group based in San Antonio, Tex.-since its inception. However, these concepts have evolved as the practice has grown and as the economic landscape has changed for reconstructive microsurgeons. In the article, we will present what we have done well, what we could have done better, and some pitfalls to avoid.

Enhanced Recovery Pathway Reduces Hospital Stay and Opioid Use in Microsurgical Breast Reconstruction: A Single-Center, Private Practice Experience.

BACKGROUND: This study aimed to determine benefits of the Enhanced Recovery After Surgery (ERAS) pathway implementation in free flap breast reconstruction related to postoperative narcotic use and health care resource utilization. METHODS: A retrospective analysis of consecutive patients undergoing deep inferior epigastric perforator flap breast reconstruction from November of 2015 to April of 2018 was performed before and after implementation of the ERAS protocol. RESULTS: Four hundred nine patients met inclusion criteria. The pre-ERAS group comprised 205 patients, and 204 patients were managed through the ERAS pathway. Mean age, laterality, timing of reconstruction, and number of previous abdominal surgical procedures were similar ( p > 0.05) between groups. Mean operative time between both groups (450.1 ± 92.7 minutes versus 440.7 ± 93.5 minutes) and complications were similar ( p > 0.05). Mean intraoperative (58.9 ± 32.5 versus 31.7 ± 23.4) and postoperative (129.5 ± 80.1 versus 90 ± 93.9) morphine milligram equivalents used were significantly ( p < 0.001) higher in the pre-ERAS group. Mean length of stay was significantly ( p < 0.001) longer in the pre-ERAS group (4.5 ± 0.8 days versus 3.2 ± 0.6 days). Bivariate linear regression analysis demonstrated that operative time was positively associated with total narcotic requirements ( p < 0.001) and length of stay ( p < 0.001). CONCLUSIONS: ERAS pathways in microsurgical breast reconstruction promote reduction in intraoperative and postoperative narcotic utilization with concomitant decrease in hospital length of stay. In this study, patients managed through ERAS pathways required 46 percent less intraoperative and 31 percent less postoperative narcotics and had a 29 percent reduction in hospital length of stay.

Prospective Longitudinal Patient-Reported Satisfaction and Health-Related Quality of Life following DIEP Flap Breast Reconstruction: Effects of Reconstruction Timing.

BACKGROUND: Without reconstruction, mastectomy alone can produce significant detrimental effects on health-related quality of life. The magnitude of quality-of-life benefits following breast reconstruction may be unique based on timing of reconstruction. Facilitated by the BREAST-Q questionnaire, characterization of how reconstruction timing differentially affects patient-reported quality of life is essential for improved evidence-based clinical practice. METHODS: Consecutive DIEP flap breast reconstruction patients prospectively completed BREAST-Q questionnaires preoperatively and at two different time intervals postoperatively. The first (postoperative time point A) and second (postoperative time point B) postoperative questionnaires were completed 1 month postoperatively and following breast revision/symmetry procedures, respectively. Postoperative flap and donor-site complications were recorded prospectively. Stratified by timing (immediate versus delayed) of reconstruction, preoperative clinical data, operative morbidity, and BREAST-Q scores were compared at all time points. RESULTS: Between July of 2012 and August of 2016, 73 patients underwent 130 DIEP flap breast reconstructions. Collectively, breast satisfaction, psychosocial well-being, and sexual well-being scores significantly (p < 0.001) increased postoperatively versus baseline. Chest and abdominal physical well-being scores returned to baseline levels by postoperative time point B. Preoperatively, patients undergoing delayed breast reconstruction reported significantly (p < 0.05) lower breast satisfaction, psychosocial well-being, and sexual well-being scores compared to immediate reconstruction patients. Postoperatively, delayed and immediate reconstruction patients reported similar quality-of-life scores. Outcome satisfaction and flap and donor-site morbidity were similar between groups irrespective of timing of reconstruction. CONCLUSIONS: In this prospective study, patient-reported outcomes demonstrate significant improvements in breast satisfaction, psychosocial well-being, and sexual well-being among patients following DIEP flap reconstruction. Moreover, preoperative differences in quality-of-life scores among delayed/immediate reconstruction patients were eliminated postoperatively. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, II.

Case Volume-Dependent Changes in Operative Morbidity following Free Flap Breast Reconstruction: A 15-Year Single-Center Analysis.

BACKGROUND: Operative morbidity is a common yet modifiable feature of complex surgical procedures. With increasing case volume, improvement in morbidity has been reported through designated procedural processes and greater repetition. Defined as a volume-outcome association, improvement in breast reconstruction morbidity with increasing free flap volume requires further characterization. METHODS: A retrospective analysis was conducted among consecutive free flap patients using a two-microsurgeon model between January of 2002 and December of 2017. Patient demographics and operative characteristics were obtained from medical records. Complications including unplanned surgical intervention (take-back) and flap loss were obtained from prospectively kept databases. Individual surgeon operative volume was estimated by considering overall practice volume and correcting for the number of surgeons at any given time. RESULTS: During the study period, 3949 patients met inclusion criteria. A total of 6607 breasts underwent reconstruction with 6675 free flaps. Mean patient age was 50 ± 9.4 years and mean body mass index was 28.8 ± 5.0 kg/m2. Bilateral reconstruction was performed on 2633 patients (66.5 percent), with 4626 breasts (70.5 percent) reconstructed in the immediate setting. Overall, breast and donor-site complications were reported in 507 breasts (7.7 percent) and 607 cases (15.4 percent), respectively. Take-back was required in 375 cases (9.5 percent), with complete flap loss occurring in 57 cases (0.9 percent). Based on annual flaps per surgeon, the incidence of complications decreased with increasing volume (slope = -0.12; p = 0.056). CONCLUSION: Through procedural efficiency and execution of defined clinical processes using a two-microsurgeon model, increases in microsurgical breast reconstruction case volume result in decreased morbidity.

Prospective Longitudinal Patient-Reported Satisfaction and Health-Related Quality of Life following DIEP Flap Breast Reconstruction: Relationship with Body Mass Index.

BACKGROUND: Breast reconstruction plays a significant role in breast cancer treatment recovery. Introduction of the BREAST-Q questionnaire has facilitated quantifying patient-reported quality-of-life measures, promoting improved evidence-based clinical practice. Information regarding the effects of body mass index on patient-reported outcomes and health-related quality of life is significantly lacking. METHODS: Consecutive deep inferior epigastric perforator (DIEP) flap breast reconstruction patients prospectively completed BREAST-Q questionnaires preoperatively and at two points postoperatively. The first (postoperative time point A) and second (postoperative time point B) postoperative questionnaires were completed 1 month postoperatively and following breast revision, respectively. Postoperative flap and donor-site complications were recorded prospectively. BREAST-Q scores were compared at all time points and stratified by body mass index group (≤25, >25 to 29.9, 30 to 34.9, and ≥35 kg/m). RESULTS: Between July of 2012 and August of 2016, 73 patients underwent 130 DIEP flap breast reconstructions. Breast satisfaction and psychosocial and sexual well-being scores increased significantly postoperatively. Chest and abdominal physical well-being scores returned to baseline levels by postoperative point B. Preoperatively, stratified by body mass index, breast satisfaction and psychosocial well-being scores were significantly lower among patients with body mass index of 35 or higher and of more than 30, respectively. After reconstruction, not only were breast satisfaction, psychosocial, and sexual well-being scores significantly improved in all body mass index groups versus baseline, but also between-body mass index group differences were no longer present. Outcome satisfaction, flap, and donor-site morbidity were similar irrespective of body mass index. CONCLUSIONS: Patient-reported outcomes demonstrate significant improvements in breast satisfaction and psychosocial and sexual well-being among patients following DIEP flap reconstruction. Preoperative differences in quality-of-life scores were improved in patients with obesity (body mass index ≥30 kg/m). CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, II.

Deep inferior epigastric lymph node basin: Analysis of novel donor site for vascularized lymph node transfer among 10 consecutive patients.

INTRODUCTION: Breast cancer-related extremity lymphedema is a potentially devastating condition. Vascularized lymph node transfer (VLNT) has shown benefit in lymphedema treatment. Due to concerns over potential iatrogenic complications, various donor sites have been described. The current study aims at defining the deep inferior epigastric lymph node basin as a novel donor site for VLNT. METHODS: A retrospective study was performed on patients undergoing routine abdominal-based breast reconstruction. Resection of all perivascular adipose and lymphatic tissue surrounding the proximal deep inferior epigastric pedicle was performed at the time of pedicle dissection and submitted for Pathologic evaluation. Patient demographics and pertinent medical/surgical history was obtained from medical records. RESULTS: Specimens were obtained from 10 consecutive patients. Seven patients underwent bilateral reconstruction for a total of 17 specimens obtained. Mean patient age and BMI were 48 years ± 9.4 and 27 ± 4.2, respectively. Fourteen out of 17 (82%) specimens contained viable lymph nodes displaying a thin fibrous connective tissue capsule overlying an unremarkable subcapsular sinus with a cortex and paracortex containing germinal centers composed of B lymphocytes, tangible body macrophages, and T-cells. The medullary sinus space displayed a fatty unremarkable hilum. The mean number and size of lymph nodes were 2.6 ±1.2 nodes/specimen and 3.67 mm ± 2.3, respectively. All patients experienced an uneventful postoperative course without evidence any of compromised flap viability. CONCLUSION: Lacking previous description, the deep inferior epigastric lymph node basin is a readily accessible donor site with significant anatomic advantages for potential VLNT during autologous breast reconstruction.

Internal Mammary Lymph Node Biopsy During Free-Flap Breast Reconstruction: Optimizing Adjuvant Breast Cancer Treatment Through Comprehensive Staging.

BACKGROUND: Accurate breast cancer staging is essential for optimal management of adjuvant therapies. While breast lymphatic drainage involves both axillary and internal mammary (IM) lymph node (LN) basins, IM LN sampling is not routinely advocated. The current study analyzes the incidence of IM LN metastases sampled during free flap breast reconstruction and subsequent changes in adjuvant treatment. METHODS: A retrospective analysis of patients with positive IM LN biopsies during free flap breast reconstruction was performed. Pre-reconstruction surgical and adjuvant therapies as well as staging and prognostic data were recorded. Change in adjuvant therapies based solely on IM LN positivity was determined. RESULTS: IM LN metastases were found on 28 (1.3%) out of 2057 patients and comprised the study population. Mean age was 49 years with pre-reconstruction chemotherapy or radiation administered in 50 or 54% of cases, respectively. Five (18%) patients had previously undergone lumpectomy with axillary sampling. Mean tumor size was 3.1 cm with tumor location evenly distributed among all four quadrants. Ten (36%) patients had isolated IM LN metastases Patients with both axillary and IM disease had larger lesions, increased prevalence of pre-reconstruction chemotherapy and radiation. Based exclusively on positive IM LN disease, 17 (63%) patients had a change in adjuvant therapy. CONCLUSION: Despite the low incidence of IM LN metastases, IM LN biopsy during free flap breast reconstruction is recommended. In 36% of cases, nodal metastases were isolated to the IM nodes. Identification of IM metastases influenced adjuvant therapies in a majority of cases.

Positive Margin Re-Excision Following Immediate Autologous Breast Reconstruction: Morbidity, Cosmetic Outcome, and Oncologic Significance.

BACKGROUND: Acquisition of negative resection margins is paramount in the surgical management of operable breast cancer. Management of positive margins following mastectomy and immediate breast reconstruction is presently poorly defined. OBJECTIVES: The present study aims at defining morbidity and cosmetic sequela of re-excision procedures aimed at clearing involved mastectomy margins in the setting of immediate autologous breast reconstruction. Oncologic outcomes are recorded. METHODS: A retrospective study of patients that underwent skin-sparing mastectomy followed by immediate deep inferior epigastric perforator flap breast reconstruction was performed. Patients found to have positive mastectomy margins underwent margin re-excision during a separate procedure. Method of positive margin exposure and resection is described. Flap morbidity and cosmetic outcome following margin re-excision was compared between reconstructed breasts that underwent re-excision vs those reconstructed after prophylactic mastectomy (controls). Cancer recurrence was recorded during the follow-up period. RESULTS: Thirty-six (2.5%) out of 1443 patients were found to have positive mastectomy margins following immediate breast reconstruction between May 2007 and November 2012. Location of positive margins was evenly distributed in all breast regions. Although flap morbidity was similar, a trend (P > 0.05) toward higher seroma formation and fat necrosis was reported in breasts following re-excision vs controls. With a mean follow-up period of 28 months, cosmetic outcome between breasts that underwent re-excision vs controls were similar. Cancer recurrence was reported in 3 (8.3%) patients. CONCLUSIONS: Re-excision of positive mastectomy margins following immediate autologous breast reconstruction requires a multidisciplinary approach and may be performed with minimal additional morbidity while preserving optimal cosmetic outcome.

Salvage of intraoperative deep inferior epigastric perforator flap venous congestion with augmentation of venous outflow: flap morbidity and review of the literature.

BACKGROUND: Breast reconstruction with deep inferior epigastric perforator (DIEP) flaps has gained considerable popularity due to reduced donor-site morbidity. Previous studies have identified the superficial venous system as the dominant outflow to DIEP flaps. DIEP flap venous congestion occurs if superficial venous outflow via the deep venous system is insufficient for effective flap drainage. Although augmentation of venous outflow through a second venous anastomosis may relieve venous congestion, effects on flap morbidity remain ill defined. METHODS: A retrospective analysis of 1616 patients who underwent 2618 DIEP flap breast reconstructions between March 2005 and January 2012 was performed. Patients with intraoperative venous congestion underwent a second venous anastomosis. Preoperative demographic data and methods used to relieve venous congestion were recorded. Incidence of flap morbidity was calculated and compared with a group of 418 controls having 639 DIEP flap breast reconstructions with no venous congestion. RESULTS: Venous augmentation was required to relieve venous congestion in 87 (3.3%) DIEP flaps on 81 patients. The superficial inferior epigastric vein or accompanying deep inferior epigastric venae comitantes was used to augment venous outflow. Preoperative comorbidities were similar between both groups. Patients requiring a second venous anastomosis had a longer operative time and length of hospital stay. Overall, flap morbidity, delayed wound healing, fat necrosis, and flap loss were similar to controls. CONCLUSIONS: Arterial and venous anatomies play unique roles in flap reliability. DIEP flap venous congestion must be treated expeditiously with venous augmentation to relieve venous congestion and mitigate flap morbidity.

Abdominal wall stability and flap complications after deep inferior epigastric perforator flap breast reconstruction: does body mass index make a difference? Analysis of 418 patients and 639 flaps.

BACKGROUND: Promoted by reports of decreased donor-site morbidity, deep inferior epigastric perforator (DIEP) flaps have gained significant popularity. Increasing body mass index is associated with poor outcomes in breast reconstruction using traditional techniques. The authors aimed to define complications with increasing body mass index among patients undergoing DIEP flap breast reconstruction. METHODS: A retrospective analysis of 639 DIEP flaps in 418 patients was performed. Patients were stratified into five groups based on body mass index. Data regarding medical comorbidities, adjuvant therapies, timing of reconstruction, active tobacco use, and surgical history were collected. Primary outcomes were compared among groups. RESULTS: The average body mass index for the entire population was 28.3 (range, 17 to 42). Increasing body mass index was associated with increased incidence of hypertension, previous abdominal operations, and length of follow-up. Flap complications stratified by group demonstrated significantly increased delayed wound healing complications in severely obese patients compared with lower body mass index groups. Donor-site complications stratified by body mass index demonstrated significantly increased delayed wound healing and overall complications among morbidly obese patients compared with other groups. Incidence of abdominal wall bulging and hernia formation was not significantly different among groups. CONCLUSIONS: Increasing body mass index predisposes patients to delayed wound healing complications in both flap and donor-site locations. Nevertheless, overall flap complications remain similar across all body mass index groups. Abdominal wall stability was maintained. Given a similar flap complication profile and maintenance of abdominal stability, DIEP flaps are recommended in patients with increased body mass index. CLINICAL QUESTION/LEVEL OF EVDENCE: Risk, II.

Breast reconstruction in private practice.

Comprehensive breast reconstruction can be performed in private practice. Our practice philosophy is that autogenous tissue provides the best substrate for breast reconstruction; the deep inferior epigastric perforator flap is our primary method of breast reconstruction. Microsurgical training and a group practice model permit routine use of all autogenous tissue techniques. Office, operating room, and hospital teams must be assembled; these teams follow clinical pathways, which make the execution of reconstructive procedures consistent and efficient. The practice must implement a plan for physician and patient education. The practice must review clinical outcomes, making adjustments in operative techniques and pre- and postoperative clinical pathways so that the best results can be achieved with a low complication rate. Breast reconstruction is a core service of our practice. We have accrued an economy of scale including these features: intraoperative and clinical efficiency, low practice overhead costs, and a high patient satisfaction rate.
