A structured pathway for accelerated postoperative recovery reduces hospital stay and cost of care following microvascular breast reconstruction without increased complications.

INTRODUCTION: Accelerated recovery protocols have proved effective in many surgical procedures but are infrequently applied in breast reconstruction. In this study, we evaluate the impact of a structured pathway for accelerated postoperative recovery in patients undergoing microvascular breast reconstruction at a high-volume center. METHODS: We describe our care pathway for patients undergoing deep inferior epigastric artery perforator (DIEP) flap breast reconstruction at our center. We compared length of stay (LOS), complication rates, readmission rates, and cost of inpatient care before (pre-protocol (Pre-P)) and after (post-protocol (Post-P)) the implementation of the protocol. RESULTS: Patients in the Post-P group (n = 198) had a significant reduction in mean LOS as compared to those in the Pre-P (n = 183) group (3.6 +/- 0.85 vs. 4.7 +/-1.04 days, p = 0.006). There was no significant difference in the rates of major (Pre-P 16.9% vs. Post-P 14.7%, p = 0.71) or minor (Pre-P 21.3% vs. 17.1%, p = 0.22) postoperative complications between groups. The readmission rates were also similar (Pre-P 6.5% vs. Post-P 4.5, p = 0.69). Implementation of the protocol resulted in a significant reduction in the mean cost of in-patient care. CONCLUSION: A simple protocol for accelerated and streamlined postoperative recovery effectively reduces LOS and patient care costs following DIEP flap breast reconstruction without compromising patient safety.

Predicting complications in immediate microvascular breast reconstruction: Validity of the breast reconstruction assessment (BRA) surgical risk calculator.

BACKGROUND: The Breast Reconstruction Assessment (BRA)-score is a disease-specific risk calculator that estimates the likelihood of postoperative complications in an individual patient. The tool has not been previously externally validated in microvascular breast reconstruction. The purpose of this study was to evaluate the efficacy of the calculator in patients who underwent microvascular reconstruction at a single specialist institution. METHODS: Data from 415 patients who had immediate microvascular breast reconstruction were entered into the calculator. The predicted and observed rates of surgical complications, medical complications, reoperation, and total or partial flap failure were compared. The accuracy of the calculator was assessed using statistical measures of calibration and discrimination. RESULTS: The calculator accurately predicted the proportion of patients who would experience surgical complications and reoperations but overestimated the rates of medical complications and flap failures. The C-statistics were low for all four prediction models (0.49-0.59), suggesting weak discriminatory power, and the Brier scores were relatively high (0.09-0.44), indicating poor correlation between predicted and actual probability of complications. CONCLUSION: These results suggest that the BRA score cannot accurately identify patients at risk for complications following immediate microvascular breast reconstruction at our institution.

A cost-effectiveness analysis of DIEP vs free MS-TRAM flap for microsurgical breast reconstruction.

BACKGROUND AND OBJECTIVES: The deep inferior epigastric perforator (DIEP) flap may be associated with less long-term donor-site morbidity compared with free muscle-sparing transverse rectus abdominis myocutaneous flap (MS-TRAM) flap. However, DIEP flaps may have longer operative time and higher rates of acute postoperative complications. We performed a cost-effectiveness analysis (CEA) that compared the long-term costs and patient-reported outcomes between the two flaps. METHODS: A retrospective cohort of women who received free MS-TRAM or DIEP flap reconstruction between January 2008 and December 2012, with a minimum of 2-year follow-up, were recruited. Cost data of the primary reconstruction and any subsequent hospitalization due to complications from the reconstruction within 2 years were obtained. Each patient received a BREAST-Q questionnaire at 2 years post-reconstruction. RESULTS: In total, 227 patients (180 DIEP, 47 free MS-TRAM) were included. DIEP patients had significantly fewer abdominal hernia (P = 0.04). The adjusted-incremental cost-effectiveness ratios found that DIEP flap was more cost-effective to free MS-TRAM flap in the domains of "Physical Well-Being of the Abdomen" and "Satisfaction with Outcome." CONCLUSIONS: DIEP flap is the more cost-effective method of autologous breast reconstruction in the long-term compared with free MS-TRAM flap with respect to patient-reported abdominal well-being and overall satisfaction with the outcome.

Preoperative Computed Tomographic Angiogram Measurement of Abdominal Muscles Is a Valuable Risk Assessment for Bulge Formation after Microsurgical Abdominal Free Flap Breast Reconstruction.

BACKGROUND: A major shortcoming associated with abdominal tissue breast reconstruction is long-term abdominal wall morbidity. Although abdominal muscle size on computed tomographic angiography has been correlated with morbidity following many abdominal operations, it has not been studied for breast reconstruction. Therefore, the authors evaluated the association between preoperative computed tomography angiography-derived measurements of abdominal core muscles and postoperative abdominal wall morbidity after abdominal tissue breast reconstruction. METHODS: In this retrospective matched case-control study of women who underwent microsurgical abdominal flap breast reconstruction at one institution between January 2011 and June 2015, the authors evaluated all cases of postoperative bulge/hernia, matched by type of abdominal flap and body mass index in a ratio of 1:2 to controls without bulge/hernia. The authors obtained morphometric measurements of abdominal core muscles on preoperative computed tomographic angiographs. Using univariable and multivariable logistic regressions, the authors examined the effects of clinical risk factors and computed tomographic angiography morphometric measurements on postoperative bulge/hernia formation. RESULTS: Of the 589 patients who underwent abdominal free flap breast reconstruction, symptomatic bulges/hernias were identified in 35 patients (5.9 percent). When compared to the 70 matched controls, multivariable analysis showed that decreased area of rectus abdominis muscle (OR, 0.18; p < 0.01) and increased inter-rectus abdominis distance (OR, 1.14; p < 0.01) on computed tomographic angiography were significant risk factors associated with postoperative bulge/hernia. CONCLUSION: Preoperative computed tomographic angiography allows objective measurements of the patient's abdominal muscle anatomy that provide valuable prognostic information on the risk of bulge/hernia formation following abdominally based microsurgical breast reconstruction. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, III.

Systematic Review: Aesthetic Assessment of Breast Reconstruction Outcomes by Healthcare Professionals.

BACKGROUND: Achieving an aesthetic outcome following postmastectomy breast reconstruction is both an important goal for the patient and plastic surgeon. However, there is currently an absence of a widely accepted, standardized, and validated professional aesthetic assessment scale following postmastectomy breast reconstruction. METHODS: A systematic review was performed to identify all articles that provided professional assessment of the aesthetic outcome following postmastectomy, implant- or autologous tissue-based breast reconstruction. A modified version of the Scientific Advisory Committee's Medical Outcomes Trust (MOT) criteria was used to evaluate all professional aesthetic assessment scales identified by our systematic review. The criteria included conceptual framework formation, reliability, validity, responsiveness, interpretability, burden, and correlation with patient-reported outcomes. RESULTS: A total of 120 articles were identified: 52 described autologous breast reconstruction, 37 implant-based reconstruction, and 29 both. Of the 12 different professional aesthetic assessment scales that exist in the literature, the most commonly used scale was the four-point professional aesthetic assessment scale. The highest score on the modified MOT criteria was assigned to the ten-point professional aesthetic assessment scale. However, this scale has limited clinical usefulness due to its poor responsiveness to change, lack of interpretability, and wide range of intra- and inter-rater agreements (Veiga et al. in Ann Plast Surg 48(5):515-520, 2002). CONCLUSIONS: A "gold standard" professional aesthetic assessment scale needs to be developed to enhance the comparability of breast reconstruction results across techniques, surgeons, and studies to aid with the selection of procedures that produce the best aesthetic results from both the perspectives of the surgeon and patients.

Barriers to immediate breast reconstruction in the Canadian universal health care system.

PURPOSE: To describe the population-based rates of immediate breast reconstruction (IBR) for all women undergoing mastectomy for treatment or prophylaxis of breast cancer in the past decade, and to evaluate geographic, institutional, and patient factors that influence use in the publically funded Canadian health care system. METHODS: This population-based retrospective cohort study used administrative data that included 28,176 women who underwent mastectomy (25,141 mastectomy alone and 3,035 IBR) between April 1, 2002, and March 31, 2012, in Ontario, Canada. We evaluated factors associated with IBR by using a multivariable logistic regression model with the generalized estimating equation approach. RESULTS: The population-based, age-adjusted IBR rate increased from 5.1 procedures to 8.7 in 100,000 adult women (43.7%; P < .001), and the increase was greatest for prophylactic mastectomy or therapeutic mastectomy for in situ breast cancer (78.6%; P < .001). Women who lived in neighborhoods with higher median income had significantly increased odds of IBR compared with mastectomy alone (odds ratio [OR], 1.71; 95% CI, 1.47 to 2.00), and immigrant women had significantly lower odds (OR, 0.59; 95% CI, 0.44 to 0.78). A patient had nearly twice the odds of receiving IBR when she was treated at a teaching hospital (OR, 1.84; 95% CI, 1.1 to 3.06) or at a hospital with two or more available plastic surgeons (OR, 2.01; 95% CI, 1.53 to 2.65). Patients who received IBR traveled significantly farther compared with those who received mastectomy alone (OR, 1.04; 95% CI, 1.02 to 1.05 for every 10 km increase). CONCLUSION: IBR is available to select patients with favorable clinical and demographic characteristics who travel farther to undergo surgery at teaching hospitals with two or more available plastic surgeons.

The Multi Centre Canadian Acellular Dermal Matrix Trial (MCCAT): study protocol for a randomized controlled trial in implant-based breast reconstruction.

BACKGROUND: The two-stage tissue expander/implant (TE/I) reconstruction is currently the gold standard method of implant-based immediate breast reconstruction in North America. Recently, however, there have been numerous case series describing the use of one-stage direct to implant reconstruction with the aid of acellular dermal matrix (ADM). In order to rigorously investigate the novel application of ADM in one-stage implant reconstruction, we are currently conducting a multicentre randomized controlled trial (RCT) designed to evaluate the impact on patient satisfaction and quality of life (QOL) compared to the two-stage TE/I technique. METHODS/DESIGNS: The MCCAT study is a multicenter Canadian ADM trial designed as a two-arm parallel superiority trial that will compare ADM-facilitated one-stage implant reconstruction compared to two-stage TE/I reconstruction following skin-sparing mastectomy (SSM) or nipple-sparing mastectomy (NSM) at 2 weeks, 6 months, and 12 months. The source population will be members of the mastectomy cohort with stage T0 to TII disease, proficient in English, over the age of 18 years, and planning to undergo SSM or NSM with immediate implant breast reconstruction. Stratified randomization will maintain a balanced distribution of important prognostic factors (study site and unilateral versus bilateral procedures). The primary outcome is patient satisfaction and QOL as measured by the validated and procedure-specific BREAST-Q. Secondary outcomes include short- and long-term complications, long-term aesthetic outcomes using five standardized photographs graded by three independent blinded observers, and a cost effectiveness analysis. DISCUSSION: There is tremendous interest in using ADM in implant breast reconstruction, particularly in the setting of one-stage direct to implant reconstruction where it was previously not possible without the intermediary use of a temporary tissue expander (TE). This unique advantage has led many patients and surgeons alike to believe that one-stage ADM-assisted implant reconstruction should be the procedure of choice and should be offered to patients as the first-line treatment. We argue that it is crucial that this technique be scientifically evaluated in terms of patient selection, surgical technique, complications, aesthetic outcomes, cost-effectiveness, and most importantly patient-reported outcomes before it is promoted as the new gold standard in implant-based breast reconstruction.

Outcomes after abdominal wall reconstruction using acellular dermal matrix: a systematic review.

BACKGROUND: Complex abdominal wall defects can present a significant challenge to the reconstructive surgeon. In 2003, acellular dermal matrix (ADM) was introduced as an alternative to synthetic materials with suggestions that it has improved capacity to integrate with surrounding tissues with less inclination towards infection, erosion, extrusion, adhesion formation and rejection compared with synthetic materials. This systematic review was conducted to evaluate the existing literature describing the use of ADM for abdominal wall reconstruction in an attempt to identify factors that may affect outcomes. METHODS: A review of the MEDLINE database using the search terms 'dermal matrix' and 'abdomen' or 'hernia' for prospective and retrospective human studies in English was performed. Exclusion criteria were animal studies, case reports, reviews and articles that dealt only with ADM for repair of congenital abdominal wall defects, hiatal, parastomal or inguinal hernias and enterocutaneous fistulae. Two independent reviewers performed the systematic review with the same a priori criteria, with discrepancies reconciled by the senior author. RESULTS: In October 2010, 3394 articles were identified as potentially inclusive based on the search term 'dermal matrix'. When filtered for 'abdomen' or 'hernia', 83 articles were found. Ultimately, 30 articles met criteria. No other systematic reviews, meta-analyses or randomised controlled trials were identified in the existing literature. CONCLUSIONS: At this current time, there is a paucity of high-level evidence comparing ADM with other methods interfering with the ability of physicians to make data-driven recommendations on clinical indications, surgical techniques and outcomes following ADM-assisted abdominal wall reconstruction.

High satisfaction rates in women after DIEP flap breast reconstruction.

BACKGROUND: Breast reconstruction (BR) is aimed at improving quality of life (QoL) after mastectomy. Patient satisfaction is an important indicator to evaluate the success of BR. This study explored patient satisfaction and its determinants in women undergoing deep inferior epigastric artery perforator (DIEP) flap BR as well as the impact of the procedure on body image, sexuality and QoL. METHODS: Patient satisfaction and QoL were studied in 72 women who underwent DIEP flap BR using a study-specific questionnaire as well as the Short Form-36 (SF-36). RESULTS: Patient satisfaction was very high. Approximately 90% of the patients reported that they had been sufficiently informed about the procedure and its consequences, that their preoperative expectations had been met, that the reconstructed breast felt like their own and that they would choose the same procedure again and would recommend this procedure to a friend. Patient satisfaction was positively and significantly related to the reconstructed breast(s) feeling like their own. Women with secondary reconstructions were more positive about changes in sexuality and femininity than women with primary BRs. There were no clinically relevant differences in QoL between our study population and a random sample of Dutch females. CONCLUSIONS: Women with DIEP flap BRs reported high satisfaction rates. However, to compare these satisfaction rates with other forms of BR, prospective studies in comparable groups are necessary.

Interstitial radiation therapy for early-stage nasal vestibule cancer: a continuing quest for optimal tumor control and cosmesis.

INTRODUCTION: This article reports on the effectiveness, cosmetic outcome, and costs of interstitial high-dose-rate (HDR) brachytherapy for early-stage cancer of the nasal vestibule (NV) proper and/or columella high-dose-rate (HDR). METHODS AND MATERIALS: Tumor control, survival, cosmetic outcome, functional results, and costs were established in 64 T1/T2N0 nasal vestibule cancers treated from 1991-2005 by fractionated interstitial radiation therapy (IRT) only. Total dose is 44 Gy: 2 fractions of 3 Gy per day, 6-hour interval, first and last fraction 4 Gy. Cosmesis is noted in the chart by the medical doctor during follow-up, by the patient (visual analog scale), and by a panel. Finally, full hospital costs are computed. RESULTS: A local relapse-free survival rate of 92% at 5 years was obtained. Four local failures were observed; all four patients were salvaged. The neck was not treated electively; no neck recurrence in follow-up was seen. Excellent cosmetic and functional results were observed. With 10 days admission for full treatment, hospital costs amounted to euro5772 (7044 US dollars). CONCLUSION: Excellent tumor control, cosmesis, and function of nasal airway passage can be achieved when HDR-IRT for T1/T2N0 NV cancers is used. For the more advanced cancers (Wang classification: T3 tumor stage), we elect to treat by local excision followed by a reconstructive procedure. The costs, admission to hospital inclusive, for treatment by HDR-IRT amounts to euro5772 (7044 US dollars). This contrasts substantially with the full hospital costs when NV cancers are treated by plastic reconstructive surgery, being on average threefold as expensive.
